you know there were Vikings in Greenland raising barley, wheat and cattle? And they did so for -~400 years between 850 CE and 1250 CE. Then it got cold. it is still too cold. Northern Europe used to produce wine as fine as anything from France. Then, in ~1300 CE they stop growing grapes. Why? It became too cold (Little Ice Age), and it still too cold. Oh, btw, grape vines take decades to grow large enough to be useful. That means it has to be WARM enough for DECADES to grow vines large enough for commerical application. Hasn't been and gives no sign that it will. When it is warm enough for cattle and barley on Greenland and has been for 300 years or so, call me.

[@rovertrobert3180]

this is the most noticeable change I have seen since I was a in my 20's. Winds have changed direction on the east coast of canada and we are having longer wind events and many more days over 50kph winds just in the past 5 years. I lived in the western end of Canada for 8 years, but was blocked in my mountains so the weather was relatively stable from the first time in went out west until a I left. Upon returning home the weather on the east coast was much different and more erratic than I had remembered. Winter with little snow then winter with 18 feet of snow ( a record). I see the jet stream slowing and oscillating to the north more and carrying warm air into the ice zones. This happened in the mid west US years ago. That event had people leaving once rich farm lands and former oasis' drying up and becoming environmental disasters (this is still a problem with air quality in the region today) This change was brought on by Jet stream changes. No one wants to consider this because there is no correlation with increased CO2 and jet stream change. Also humans dont know shit about this planet anyways so why do we listen to government agencies and paid propaganda campaigns forcing us to pay for a natural non man made problem.

[@christinearmington]

Rovert Robert Jennifer Francis from Rutgers University has predicted for the last decade that increasing temperatures in the arctic will cause deep waves or amplitude in the jet stream. This is caused by the decrease in temperature difference between the equator and the North Pole. The lower gradient in temperature causes the jet stream to slow down so that not only are the troughs and ridges deeper (that amplitude), but they linger longer , keeping weather patterns in place longer. Since CO2 raises temperatures, there’s the connection to the jet stream.

Well Veronica as long as you've got a couple of cases of wine before it goes to $500 a bottle, you can keep the mood a little more cheerful at your place. Don't forget a couple of solar panels on the roof and a small air conditioning unit in the window can keep at least one room cool while it's 120 to 130 degrees Fahrenheit outside. You'll become the hit of the neighborhood with that rig. Add wine, and ice maker, perhaps a water filter, since that infrastructure will likely collapse also and you'll be a lot more than a party.

Well I spent 20 years buying Beachside homes in Southern California, and finally threw it all away to move into a school bus and travel the coast, then made the transition to a sailboat at anchor where I make all my own power, as much water as I want, and I'm building my little garden onboard. It'll be enough food for me and I highly recommend everybody follows that pass. You can get a sailboat big enough for a family of 5 for a couple hundred bucks at any Marine Harbor lien sale auction. If you're on the west coast there's a magazine called Latitude 38, but anyone near a coastline can make a list of 20-50 Harbors, call each one and ask when their next lien sale will be. Go there with $500 in your pocket and someone who knows how to sail, walk away with a home that will last you for the rest of your life. Make sure it has good rigging and sales and a Rudder. You can always fix the engine and the electrical components later. Slap an outboard on the back and Away you go. Stock it with a year or two of food, build a water maker or two that works entirely off solar, then put the rest of your money into small solar panels and eventually larger ones and a small wind generator rig with some spare brushes and bearings. That will give you power for the next 10 to 20 years. And when temperatures go off the charts you can take your new home down to the southern hemisphere where you'll be close to the last ice on Earth that exist, and unlike your Northern Hemisphere Neighbors, you won't boil your brains out on a lazy summer day.

@@enerzise3161 I've yet to see anybody deny the validity of ice cores for telling us the CO2 content of the air all the way back to 2.7 million years, a thousand times longer than humans have been around but not very far when it comes to the age of the earth. I've yet to see anybody claim the melting of sea ice will raise sea level. There are 3 rising sea level arguments (1), the melting of land supported ice e.g. Greenland ice, Antarctic land ice (2) thermal expansion of sea water (3) the rising of land that has been relieved of the weight of ice it once supported. We have entered into what would be a cooling phase of our present Milankovitch Cycle and indeed temperatures were slowly falling prior to the industrial revolution that got underway around 1750, they have been steadily rising since and at ten times the rate they were falling. Too much other stuff to comment on other than to say temperatures are rising at a rate evolution cannot cope with and that is before you factor in the methane bomb (which may not happen but probably will) from shallow Arctic seas and thawing Tundra (methane already counts for a third of the warming with CO2 and some trace gases accounting for the rest).

Co2 moves around in pockets and then there is the overall average. It must stay above 149 PPM or all live on earth will start to die because the trees, grass and plants need it to be above that or they start to die. Then everyone and all the animals start to die because the trees, grass and plants converts Co2 into Oxygen. Skyence is fake and Denies Real Science.

@@myra7273 Tim is being sarcastic. He knows it was warm because the Jet Stream went south as it does from time to time. During the last great ice age, the same area was warm, while there was a 1+ mile thick ice sheet covering most of Canada and the North East USA. The Jet Stream goes south and eventually north again and it does that no matter what the Co2 is doing. Droughts are worst during an ice age and flooding is worst in an ice age and freezing long term unending winters are worst in an ice age and they are in specific locations on earth all at the same time. The ocean is about 400 foot lower than it is now and sometimes the Co2 is higher than it is now. The Co2 is about 410 PPM and has been up to 4,000 PPM in the past. The Co2 has never in history prevented the 50,000 year glacial period from starting. No matter how high is has been. 400+ PPM Co2 is not high, it is low for the earths history of Co2. Co2 in the 1930's was about 300 PPM, yet the North ice was melting and the USA thought an Ice Age was starting. You can read it in the 1930's papers of the time. The most EF-4 and EF-5 Tornadoes in American history in the 1930's also and the most expensive hurricane to hit the USA was in the 1930's also(Miami, Florida). The most bridges lost to flooding and storm surges damaging cities and killing people in the 1930's. All in the papers of the 1930's. In 1926 the volcanic activity in Hawaii were erupting just like it had been for the last few years. These eruptions in 2017 and 2018 were considered worst than the 19026 eruptions. So we might guess the next ten years or in 6 to 7 years the same cycle would hit, though it could have started a couple years ago because these cycles are not exact. They can vary by ten to twelve years either direction.

And no, it's not just gonna affect some far away 3rd world countries (which happen to produce most of the stuff you consume), it's gonna hit you right here. All the past recessions, hunger and wars can't compare to the scale of impact we are in for. Our economy is not built to deal with an accelerating crop loss as well as exponential intensity and frequency of extreme weather events. It's not a temporary event that can be waited out and gonna fix itself somehow. This is real, big, and happening now. The 6th mass extinction, accelerated 10-fold by homo sapiens. And no, it won't take thousands or hundreds of years to unfold. A decade at best, but I wouldn't count of the second part of this decade as livable anywhere on this planet. Once we start losing crops, we will start losing people, and once we lose 20-30% of the population, we will start losing the nuclear and chemical plants around the world. We have over a thousand nuclear facilities that need 24/7 maintenance and monitoring. To safely decommission even a single one takes millions to billions of US dollars!

[@latitudetwentyfive]

@ Huitzilo Pochtli.... Hmmmm nice rant and no facts. Please visit today " Trading Economics" Commodities section and check out the agricultural section which shows how prices are moving and check out history of grain price movements as climate has changed. You will find during cooling episodes (Dark Age) grain prices soared and empires imploded and during warm periods (Medieval Warm Period) grain prices declined and humanity thrived along with empires. Please review history of humanity. We should be celebrating the warm times we now experience and the incredible advancement of humanity in the last 200 years because these times will not last. The next cooling event is with us now and will become more apparent in the next twenty to thirty years. Please do some proper climate research over at least the last 100,000 years and study the long term cycles instead of what has happened in the last 170 years. A good place to start would be with reviewing some you tube video's of the late professor Bob Carter formerly of James Cook University and look into the East Anglia climate email scandal and the infamous Michael Mann hockey stick scandal. Nobody doubts that there has been warming since The Little Ice Age ended and humanity has via CO2 emissions made a small contribution to warming but it has not been proven to be dangerous global warming. You should be skeptical of the IPCC which is an instrument of governments and who can trust governments these days. Unfortunately governments have their global warming narrative now tarted up as "climate change" so they can tax the air we breathe and big business can profit from green energy. The climate scientists rely on government grants so they can eat too and their skewed findings are further manufactured to fit the narrative when compiling the IPCC reports. It should be noted that I am personally against emissions of actual particulate pollutants, and agree fossil fuels should be left in the ground. Unfortunately, there is too much money to be made in the fossil fuel industry and alternative sources of free energy are being suppressed. Good luck with your research. Cheers from OD

[@samlair3342]

I appreciate you introducing the concept of “latent heat of fusion”. (and more material, in such an actual factual way). Truly, I’d had no idea about this. The more I read about the particulars of global warming, the more I realize how complicated the overall ‘artificially induced climate change’ situation is. Your raising all of our levels of consciousness is a valuable contribution towards mitigating global warming. If I understand correctly, the amount of heat energy that is needed to melt ice in contact with water (sea ice) is the same amount of heat energy that would be required to raise that newly melted ‘0 degree Celsius water’ to ‘79 degrees Celsius’ (scalding hot water). Thus, when sea ice is no longer acting as a heat sink, the ocean water takes on the full thermal warming effect of the sun (plus, the reflectivity of the ice is gone). Here’s some sites I visited to help understand it better: Heat of fusion - example problem - melting of ice: www.thoughtco.com/heat-of-fusion-melting-ice-problem-609498 Enthalpy: en.m.wikipedia.org/wiki/Enthalpy How to measure heat of fusion of ice: sciencing.com/measure-heat-fusion-ice-8097648.html Latent heat: www.britannica.com/science/latent-heat

[@samlair3342]

Note: I shared this something ‘new to me’ with my middle aged daughter knew all about it already. She’d learned about latent heat of fusion during her freshman year in high school. She admitted, though, that she hadn’t thought about it in relation to climate change. Thus, she says that she appreciates your sensible approach to bringing scientific knowledge to bear on the subject of climate change.

This is why the 50,000 year warming peaks will get progressively weaker. #7 NEVER in the past has the Co2 stopped the earth from cooling back into an ice age over the 50,000 year glacial period cycles. Not even when the Co2 was 1,000 PPM and it is only a measly 410 PPM. #8 If you take the top 4,000 PPM and estimate an average from the known low of 250 PPM during World War II, the current 400+ PPM of Co2 is considered low for earth. LOW, not HIGH. Recap; A. The Co2 is low, not high for 400+ PPM B. This warming is weaker than in the past 50,000 year warming cycles. C. Co2 does not stop the 50,000 year glacial cycles. D. The warming over the last 250 years is part of the 50,000 year inter-glacial cycle. E. No, it is not a threat, it is 100% natural and remember it is weaker. F. Satellite Data does not show the billions of years of KNOWN data on climate cycles. G. The 50,000 year warming cycle ended about 20 year ago. H. A 50,000 year glacial cycle is starting and this is why the earth is experiencing the shifts. I. There could be up to 8,000 years of energy built up in the earth that needs to bleed off. J. The Oceans will not rise from sea ice melting because it is already in the ocean. That glass could be filled with ice and then top it off with water and if all that ice melts, the water will not rise. That is known scientific fact. K. The current climate conditions are not out of the ordinary for a 50,000 year inter-glacial period, at the peak of a warming period, for earth. There have been millions and millions of them that were warmer than this and the Co2 was higher than this. L. The ice sheet was over a mile thick and covered most of Canada and some of the North East states of the USA, back 45,000 years ago. Where is it now? It has been warming for the last 50,000 years,not just 250 as the Science Deniers claim. This is how Real Science is Presented. The video is Cult Religion SKYence teaching.

The fact is, solar forcing models HAVE been studied, to death. Every climate model worth its salt is tested against all kinds of forcings, including solar. If there was any one which showed a significant correlation signal, we'd know about it. More importantly, those studying it would get all the funding they needed to do so. >They all know this very simple fact so they don"t try because the game is rigged by IPCC and all the BIllions of research dollars. The IPCC has no control over any funding whatsoever. That is controlled by national governments and both public and private institutions. You seem to have a misunderstanding as to how science works. People don't get grants and research dollars for rediscovering the same thing over and over again. They get money for things that upset the applecart of the norm. Yes, I know it doesn't always work out that way, but most of the time, human behavior and capacity for screwing up being what it is, the incidence of its effects in the pursuit of science shows it has the least effect overall. If someone comes along and publishes research which shows that current climate science has it all wrong, and their explanation of the evidence is provably better than what currently exists, they'd be lauded. Nobel Prize material. It may take years or even decades for it to be thoroughly reviewed and tested to the same degree as current theories, but that's what should and does happen. >Can you honestly state that current research knows all the solar radiation effects on our planet thermal cycle? ALL of it? No. Science never assumes it knows ALL of anything. That's what makes the scientific method so powerful. People (scientists) can go back to review things that were previously researched and find new evidence and postulate different or even better theories that fit ALL of the evidence better. They can also improve the methodologies as technology to do so advances, improving the quality and accuracy of the data. There are Nobel Prizes and grants a-plenty for ANY scientist who comes up with better research and explanations for how the world works. That said, the question then becomes "Do we know it well enough?". You (and others) argue that we don't. The thing is, radiation and its effects has been researched by thousands upon thousands of scientists for hundreds of years. I think that we know it well enough to make useful and accurate measurements and postulate theories about its effects upon the natural world, even on the grand scale of the entire planet's energy budget. Is it going to be accurate down to the 20 9s degree? No, but it doesn't have to be, because that level of accuracy isn't necessary to make useful models and predictions. >Realize that only 0.01 % increase or decrease in total solar radiation would invalidate any climate model. You obviously don't know what you're talking about. The 11-year solar cycle causes TSI to vary by 0.1% by itself, and variations in Milankovich cycles can be up to 25% locally over long periods, though global averages are much smaller. Climate models are /specifically designed/ to take into account TSI and observed variations in it, but even the real data doesn't show a correlation signal for values less than what the solar cycle causes for its length. TSI has been measured for decades now, and there is no evidence that it is increasing sufficiently to be a significant contributor to climate change. However, if you have some evidence to the contrary (that you actually understand which is relevant, and not cherry-picked garbage from denier blogs), please do share it. >The sun's energy and ALL frequencies of energy transport to the earth is still not fully understood even though all the energy comes from the sun for heating/cooling "climate change". Nothing is ever "fully" (read: absolutely, 100%) understood. The question is whether or not it is understood "well enough". The research is showing, after many decades now, that is indeed the case. >Yet, "climate scientists" state that CO2 is the ONLY reason for any "climate change". No they don't. They say that GHG (not just CO2, btw) emissions from human activity are the *most likely* cause of the current shift to warmer temperatures. Literally thousands of lines of evidence seem to back it up. No other explanation that has been tested has shown anywhere near as strong a correlation as CO2 and other GHGs. You can't just hand-wave it all away, unless you have some SERIOUS evidence or testable hypothesis to back it up, and you don't. >Any thinking person realizes this is total nonsense to ignore the lack of understanding of solar forcing for ALL frequencies (x-ray, gamma, etc etc) Yet, they *HAVE* been studied, REPEATEDLY. Their effects are understood well enough to know what their effect is on a warming atmosphere. The vast majority of the Earth's heat budget comes from a very small part of the EM spectrum, specifically in the UV and infrared regions. They absolutely dwarf other sources by many orders of magnitude. Variances in those other sources are far too small to contribute significantly to the observed warming. It's a simple matter of physics. >and then tell everyone to spend Trillions of dollars per year (which most proposals will ultimately cost) says only CO2 levels are to blame for climate change Again, NO ONE says CO2 is the "only" source of global warming. It *IS* the most significant contributor, and GHG increases contribute to the vast majority of it. It is the single most effective one we can address, too. Sure, it will cost a lot, but it will also create jobs, contribute to the economy, and we're going to have to do it eventually anyway, because fossil fuels WILL be used up at some point. Might as well get started now, EVEN IF climate change from global warming is all a hoax, as you and other deniers claim, we'll have created a better world for "nothing". >and the solar minimum/maximum have nothing to do with perceived global warming.

Changes in ice volume at the poles and in land-based glaciers over time are a normal effect of cyclical changes in climate. No one can dispute that. The theory that human made CO2 is the cause of it lacks any kind of proof if you are serious about science. There are just two models. One calculates the global temperature anomaly (HADCRUT4) and the other (35 of them) calculate a climate response to greenhouse gases. None of these models correlate with real measured temperatures. The hottest year on record is when the calculated anomaly is 0,05 degrees warmer. When that does not work they call it the hottest decade meaning they average out temperatures even more. But all this information does not prove in any way that the change that we see now is in any way going to be a catastrophic change. It is proven that GREENland was much warmer in the middle ages and the climate did not catastrophically collapse. The climate models all use a guess of water vapour feedback forcing that is not observed. They constantly have to adjust the parameters for areosols and have no clue how they influence the climate. The human emissions of CO2 have risen dramatically but the rise in global CO2 every year is completely steady. This proves that the amount of CO2 in the atmosphere is not proportional to human emissions and therefore not causal for temperature change. The Bern model simply assumes that human made CO2 will stay in the atmosphere for 200 years while the C14 measurements prove it is for sure less than 20 years. So the proposed accumulation of human CO2 is simply nonsense. The effect of the Milankovich cycles in solar radiation is in the range of 100W while CO2 can be at most 3W. The Milankovich cycles correlate perfectly with the speed of change in ice mass. The temperature changes over thousand of years correlate closely in the Fourier analysis with the cycles of the planetary motions of the largest planets that cause a change in the suns internal plasma flows and as such the suns radiative energy. All that has to be taken into account and clarified before we start to kill our energy production and thus our prosperity. Everyone knows that humans will not manage to reduce CO2 in any effective way as long as the population grows. So now they talk about humans having to stop to have children. And the Western youth has been indoctrinated to believe that. The rest of the World does not know and does not care. So what will be the consequence of CO2 reduction in the West???

Peter spent decades in the arctic measuring the decline of ice. His view is that a blue ocean event will most likely not happen this year, but is very possible indeed before 2030.

[@jk35260]

Here is the "good news". Latent heat of vaporisation is 2260kJ/kg. That is 6.8 times more energy required than latent heat of fusion. So evaporation will help slow down the rate of heating at the surface. But that is going to cause air to be more humid which will condense once it reaches the higher atmosphere. That also means the upper atmosphere will heat up faster than any other region. Mountain glacier especially those at the Himalayas as rate of melting will increase due to an increasingly warmer atmosphere. Other effect includes more severe storm, flood and hurricanes.

This is a rare instance in which mixing in old imperial measurements make it easier to follow that using SI units. By definition the heat to raise the temperature of one gram of ice by one degree is one calorie (small 'c'). So the heat to melt a gram of ice is 79 calories or as he said the same heat as it would take to heat that water up to scalding. Now here is the real kicker. The heat to evaporate that gram of water is enough to raise it 5 times from zero to 100 degrees C and then, in addition, from freezing to 40 degrees C. Think of the implications of this.

[@MiniLuv-1984]

Thanks, excellent info, well presented as usual. I was blown away by the fact of the latent heat of fusion, were it be used to heat liquid water from 0oC would raise its temperature to 79oC. I knew of the effect, but had no idea of the scale. I wonder if you could also do a similar flip-side report - the state of the Antarctic sea ice?

[@batzing]

The problem is the lack of long term data. 150 years makes it statistically impossible to derive conclusions from this short term pattern. We also have historical sources that document transits between coasts in summer as early as 1904 (and older). This indicates open water in the arctic in the near past.

[@davecan1103]

Absolutely true. Moreover I would really like to see a detailed analysis showing what effect would there be on naturally occurring climate change if every single provision of the Paris Accord were met by every nation. What you say is very true though, the extent to which CO2 is affecting the course of naturally occurring climate change is vastly exaggerated in the current climate models which has been shown to be true by the very scientists that created this model in the first place. I sincerely have my doubts that currently existing climate models are close to being any kind of valid or proven working predictive model. It's a start but I think there's many many years to go before we have a really truly robust model of our climate system. Of course we all know that Greenland used to be completely ice-free, and it will one day again be ice-free. Naturally occurring climate change is not in any way completely understood, the role of CO2 in anthropogenic warming is vastly exaggerated in the currently existing models. I would be much more interested in seeing studies of the model itself such a sensitivity analysis and predictive accuracy, rather than a bunch of data about melting ice caps that simply presumes that it is man-made inputs that are causing it. This video merely shows what is happening in the current state of climate change, but by no means does it show any correlation whatsoever between man-made CO2 production and climate change. Perhaps for the more scientifically educated folks I'm much more interesting and valid discussion would be centered on the models themselves, their validity, the data that was used to derive the models, their predictive accuracy, and the remaining factors that do not even get accounted for in the current sparsely derived climate models from very limited data. I realize that many may find this boring and prefer to just automatically believe that man is making the ice caps melt, but more time spent on discussing the climate model and how we can improve it would be much more productive in my opinion

[@alexjackson1863]

@@davecan1103 You can already observe how bad a predictor the climate models are. Just take the early IPCC arctic ice predictions and compare it to actual arctic ice. The models vastly UNDERSTATE the actual ice loss. This is because the models do not take into account the albedo effect (loss of), methane releases, water vapour etc etc. The IPCC mainly focused on CO2 and did not include other warming positive feedbacks. In essence the IPCC vastly understates global warming, that is why their prenouncements are coming out more frequently with more dire implications. The IPCC is playing catch up with reality.

[@batzing]

@@alexjackson1863 In 2018 we saw an increase in Arctic sea ice. This year is colder so we expect even more growth. Regardless evidence exists that suggests this may be a natural cycle unrelated to global warming. Hard to make a call due to small data set. We've only been tracking it a short time. Keep in mind CO2 emissions have been steadily increasing since the mid 1940's. Yet we are seeing a cooling period. The Alarm in this case is very likely unwarranted.

[@HushemFlupskluk]

Unfortunately the arctic sea ice volume is well within the 2004 - 2013 median polarportal.dk/fileadmin/polarportal/sea/CICE_curve_thick_LA_EN_20190314.png and the sea ice extent is getting into the 1981 - 2000 median polarportal.dk/fileadmin/polarportal/sea/SICE_curve_extent_LA_EN_20190313.png

[@bigJovialJon]

When I look at the ice volume graph, the first thing that I notice is that it has been below average almost all of the several years, and the ice extent graph has been below two standard deviations almost all of the last several years. Neither of these are good. The latter is like your kid's teacher saying, "If they work *really hard* the could get get their grade up to a D." The DMI's trend graph makes it pretty clear that we are well below historical values. ocean.dmi.dk/arctic/icecover_30y.uk.php

[@OldScientist]

This isn't aging well. NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades, and May 2023 was the coldest on record in the Arctic.

"Just have a think", thank you very much for your great work. While it's great to speak with open people that have a radically different opinion on controversial issues, the kind of quarreling of the kind I see plentiful in this section, is a waste of time. If nobody is learning anything in a conversation, then quit it.

Hi Giancarlo. Thanks for your feedback. I haven't noticed the quarrelling to be honest. I don't actually bother to read the comments from the industry sponsored deniers.

[@chrysalicechristopheranderson]

Any point in making the following suggestion? Use Graphene, Graphene Nanotubes and Aerogel made in a vaccuum. Build billions of billions of (billions of...) micro sunlight-reflecting umbrellas (say, sub-mm). Each has top surface near-flat to reflect, a weighted handle to make the top stay floating horizontally and the say 45deg cone body filled with the Aerogel, sealed with low pressure air (maybe all GHG filtered out...) so each "sunbrella" has a very accurate overall density to float up to a set altitude when/where released. These would be released from Spring through Fall/Autumn around the shores of the Arctic Ocean whenever the winds are northerly. Someone-else can decide the best altitude for these, but airplanes should survive flying through these things but should avoid doing so... Objective is of course to shield the Arctic to halt temperature rise there, to halt melting of permafrost and heating of the Arctic seabed to prevent tripping any mass-release of GHG there - while we buy time to wind back the upper atmosphere GHG concentrations to pre-1960 levels ( or lower...). Might work, eh...

Thank you for that very informative video. I have been pondering on the climate lately as I grow my own organic food . I never use chemicals and encourage beneficial predators such as ladybirds lace wings hover flies predatory spider mite and parasitic wasps, to control the pests such as greenfly,thrifts, 2spoted spider mite, caterpillars etc .So I'm extremely use to stepping outside and spotting a insect in seconds. But that is not the case this year. They have all vanished. I can honestly say I have knot seen one ladybird, lace wings or parasitic wasps all summer (I am in the southern hemisphere 11 march 2019 ) even the porch light has no moths beetles or lacewings.I real fear this is knot looking good.

Hi Timmy. Your hands on experience chimes quite well with the conclusions in the report I looked at last week from the Institute of Public Policy Research here in the UK. kzbin.info/www/bejne/j3uqn4x3n7prhbs Not a very optimistic picture for insects I'm afraid. And of course that has the inevitable knock-on effect for all species, including us.
