Hopefully, you and I and others are reacting to reduce our carbon/energy use. When my house gets restuccoed I am seriously considering adding more exterior wall insulation and bringing attic insulation to R50 or more. That's an intergenerational energy conservation reduction in GHG emissions and builds resilience in the face of adverse events like in Texas that may likely become a more frequent phenomenon. Texas, aside from joining Tres Amigas power switching station should be embarking on long term home and business conservation funded by adopting a state climate/energy fee and dividend system. Do it soon. Oh and my south facing vertical 8'x24' solar hot air collector will have two of its 4'x8' lexan panels replaced this year as it deteriorated after 25 years.

Clearly their food change is broke. The east coast has the weakening Gulf Stream issue, measured at -15% weaker. This means the lower nutrient that requires lower colder waters to move up to provide feed is failing. Unfortunately fossil fuel use/carbon production is pumping along nicely. The Oceans will need centuries to cool & filter pollution, certainly not in our time.

As a general rule of thumb, growth rate of organisms increases with an increase of temperature. (as you mentioned) You get about a doubling of growth for every 10 degrees C rise. This carries on to just before the lethal temperature. The growth doesn't decrease above this temperature in a nice bell curve but drops off a cliff. Organisms die and there is of course no further growth. Corals, as an example, in many locations, are growing at just a degree or three below their lethal temperatures and hence coral die off.

Indeed, we know the rates of changes of atmospheric CO2 from ice cores. The Vostok Antarctic core, for example, which goes back 420,000 years, shows that the greatest RATE of change in all that time was just 30ppmv in 1,000 years. We are now increasing atmospheric CO2 by 30ppmv in little more than ten years - nearly one hundred times faster than the natural changes associated with the climatic convulsions of the ice age.

What many people fail to grasp is that, though the oceans may cover over 70% of the earth's surface, it is relatively wafer-thin. Even the deepest point is less than 1/1000th the diameter of the planet, and the average depth is less than half that.

@@helenlawson8426 How it does not work. By reflecting away 30% of the incoming solar radiation the albedo, which would not exist w/o the atmosphere and its so-called GreenHouse Gases, makes the earth cooler than it would be without the atmos/GHGs much like that reflective panel propped up on the car dash. Remove the atmos/GHGs and the earth becomes much like the moon, an arid, barren rock with a 0.1 albedo, 20% more kJ/h, hot^3 on the lit side, cold^3 on the dark. If this is correct, the Radiative GreenHouse Effect theory fails. For the GHGs to warm the surface with downwelling energy as advertised they must absorb/trap/delay/intercept “extra” energy from somewhere in the atmospheric system. According to RGHE theory the source of that “extra” upwelling energy is the surface radiating as a near ideal Black Body. As demonstrated by experiment the surface cannot radiate BB because of cooling by the non-radiative heat transfer processes of the contiguous atmospheric molecules. If this is correct, RGHE theory fails. How it does works. To move fluid through a hydraulic resistance requires a pressure difference. To move current through an electrical resistance requires a voltage difference. To move heat through a thermal resistance requires a temperature difference. (Q=UAdT) Physics be physics. The complex thermal resistance (R=1/U) of the atmosphere (esp albedo, net Q) is responsible for the temperature difference (dT=Tsurf-Ttoa) between the warm terrestrial surface and the cold edge of space (32 km). And that process involves the kinetic energy of ALL of the atmospheric molecules not just 0.04% of them.

@@nxgrs74 You need to go away and learn some science rather than just keep on typing lists. Greenhouse gases work in a number of ways but the main two are... Incoming energy from the sun passes through the greenhouse gasses as they are opaque at the incoming frequencies but on the return trip into space the same rays are now at a frequency where by they interact with the CO2 and energy is reflected off in all directions some of which is of course back down to the ground. From this the ground gets a bonus bit of warming. This is I believe (but not sure) is how greenhouse gases magnify the heat capture of water vapour. The other is the radiative forcing which is really hard to explain but here goes (I'm not a scientist)... Again the atmosphere is pretty opaque to the suns rays and again the more co2 there is the higher up the radiative transfer of heat from our atmosphere into space happens. This higher altitude is a cooler and so the speed of heat transfer is lower. Now as the energy in must equal the energy out the atmosphere warms up until the heat being released at this new altitude matches once more the rate it had at the lower height. reduce the greenhouse gases the atmosphere cools until it all equals out again. Please don't take my word for this it is really old and basic science even if I struggle to explain it. These are basic atmospheric mechanisms used to also model what is going on on other planets.

Why build wave energy machines when seagrass and other aquatic habitats can absorb wave energy. Same goes for wind turbines, tree are much more important absorbers of wind energy. Where does the money come from to spend on ecological restoration if we spend on wind and wave machines?

@@Flumstead None of those things create energy and replace greenhouse gas creating power stations we have now. It has to be a two pronged attack of stopping burning stuff and trying to get as much of our human created co2 out of the atmosphere as possible. Ecological restoration will help reduce some of the co2 and help the environment on the way, wind & wave electricity production will reduce what we produce in the first place. Restoring are seas are less a case of spending money and more a case of changing the industrialisation of fishing our seas into something less harmful.

Thank you for another really informative video! This one really gets to the heart of that old belief that we could never alter anything as big as nature.

And once we get to that limit it's much harder to remove the carbon dioxide, since there's so much of it. Our global civilization is like a man diagnosed with coronary disease, and those multibillion dollar green recovery plans you mention are like the doctor's prescription of diet and exercise.

Thanks Dave for the fizzy overview of our oceans in flux. Is there any chance of geo engineering helping??

[@JustHaveaThink]

Hi Chuck. Not sure about any geoengineering 'solution' really. We're just doing more tinkering with a system that we don't know enough about. Also the volumes of materials to effect any real change are pretty mind blowing and may require more energy, and therefore more heat /CO2 release than the good they might do.

[@Jcewazhere]

@Just Have a Think (aka Dave) We've released enough CO2 to make a measurable impact on the composition of the atmosphere. Has there been, or why hasn't there been, a corresponding decrease in the O2 content of it? We always hear about CO2 PPM, and sometimes about methane or other greenhouse gases. Is it just because of their outsized ability to trap heat compared to a minor, or no, decrease in O2 concentration?

[@JustHaveaThink]

No significant change to oxygen levels. But you've touched on the real point. Greenhouse gases just happen to have a molecular arrangement that can absorb photons of infra red light. Oxygen does not do that. Water vapour does though, which is why it is by far the most dominant greenhouse gas of all. But water vapour is pretty much in balance, which is why it is not a driver of increased warmth - at least not until recently. CO2 is increasing so quickly that it is having a forcing effect on temperature. For every 1 degree Celsius of extra heat, the atmosphere can hold 7% more moisture, so now the CO2 IS forcing an increase in water vapour which is exacerbating the problem. Just one more feedback loop to add to the list.

[@Jcewazhere]

@@JustHaveaThink I knew about water being a GHG, and the absorption of CO2, but the rest is new to me. Thanks for the response :) Yeah, as it gets warmer and the air is able to hold more water it'll become overall more insulating, which makes it hotter, which means more water... runaway cycles like that are everywhere. One thing that may help convince some fence sitting mechanically inclined people that climate change is dangerous is comparing it to a runaway diesel engine. That's a self reinforcing runaway cycle that they can easily see and understand. If you don't stop the runaway quickly it means the engine will destroy itself. Unfortunately while it's easy to stop a runaway engine if you know what you're doing it's not so simple to stop any of the climate runaways. If you're curious: Block the exhaust, use a CO2 fire extinguisher to starve the engine of air, or put it in a high gear and drop the clutch, though that last one may destroy your transmission.

[@TheSpecio]

CO2 in water is NOT an acid, just a physically dissolved gas. Carbonic acid is the product of a chemical reaction where 1 CO2 molecule and 1 H2O molecule become H2CO3. This molecule isn't acidic either. But it can dissociate to HCO3- and H+ (acidic) or (CO3)2- and 2 H+ (acidic). ALL forms are in equilibrium, depending on pH, saturation and temperature. All forms also interchange perpetually. At pH 8.3, for example, the 'Carbonic acid' is made of 50% H2CO3, 50% HCO3- + H+, almost none is (CO3)2- while the vast majority is, of course, just CO2 dissolved in water.

[@RobinTJKershaw]

[@zandemen]

Here's some food for thought; your analysis of ocean acidification is at best superficial. There are many other factors you did not even mention, like haline cycles. Increased temperatures increase evaporation, increased evaporation increases the density of water and that heavier water falls. Cold water upwellings from the deep replace the surface water. In this way heat increases the transfer of water from abysses, along with nutrients. Another factor is that increasing energy in any system increases convection currents. Another factor you didn't mention is tidal currents, which are wholly unaffected by temperature. They are the most significant factor in water exchanges and mixing, responsible for most of the displacement of surface water and movement of cold and nutrient rich water from depth to the surface. In fact, with increased volumes of water from heating tidal currents will increase in speed and will tend to mix the water columns even more. This is due in part simply to increase volume, but there is a compounding factor of laminar flow, where increased depth of water increases velocity in a super-linear fashion. The most productive fishing grounds in the world are commonly found in the areas where upwellings from tidal currents feed ecosystems. None of this is affected by temperature, or acidity. Another factor, increasing temperatures increase precipitation from that increased evaporation I talked about earlier, along with increased convection currents. When the convection currents carry up warm moist air and it cools, the condensate falls out and increases precipitation. this precipitation does a few things, one is erosion of land masses, which can increase flow of nutrients to the oceans, increasing productivity, particularly when it provides comparatively rare nutrients which are a bottleneck for phytoplankton growth. Also increases turbulence and haline cycles mixing of layers. So, you can pick one argument and counter it and act like you've proven which way things are going, but as long as you're cherry picking, stick one up your ass to stop off the bullshit you're spewing.

@7:00. That in depth presentation really show how ecosystem is complicated.

Then what can one say about reduction in amount of available light? Isn't it in contrast with faster growth?
