The three myths of climate change | Linda Mortsch | TEDxToronto

Even if you believe climate change is real, you probably still hold a few myths in your head about the impact a changing climate will have on your life. A leading climate scientist helps sort fact from fiction and stresses the importance of adapting to an uncertain future. Linda Mortsch has devoted her career to addressing climate change issues. Since 1989, she has played a role in the Intergovernmental Panel on Climate Change (IPCC), and is a co-recipient of the 2007 Nobel Peace Prize. In 1992, her research project “Adapting to climate variability and change in the Great Lakes Basin” was one of the first to explore adaptation to climate change in Canada. Today, Linda has an adjunct appointment in the Faculty of Environment at the University of Waterloo, and has been recognized by a number of associations, including the International Joint Commission, American Geophysical Union, Environment Canada, and more. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

There has never been any time in human history when people didn't have to adapt to climate change. This is what we do no matter what the cause so let's get over ourselves and stop politicizing it.

[@Magik1369]

umm...duh. The entirety of human history and civilization has taken place in a stable climate that has never varied more than +/- .5 deg C. From the 1750's baseline, the planet is now at 2.2 deg C above the original baseline. This is catastrophic warming that we are experiencing right now and it is a portent of what is coming. That is, heat death from wet bulb conditions, starvation, and dehydration...for every human being. NO human being can survive what is quickly unraveling now. We are lucky if there is another human being standing on Earth by 2026. Abrupt exponential climate change does not care whether you understand it or believe in it. Climate change will kill you anyway...within 5 years.

This is not not to compare - Mars is much further from Sun than Earth and the atmosphere is also muuuch thinner than that on the Earth. But other than that I agree with Jacob Meyerson and I believe, that there are many holes in the "human caused boiling" theory and the we as humanity have to persist in seeking truth and do it in scientific way and not in political way. Politicians and alarmists are not here to talk about climate change at all. Most of them do not have any education in science at all.

[@michaelclark4876]

Someone should have answered your questions by now. I can see why someone would have them and there are what I think are straightforward answers I hope you are OK with a little reading.. This is a really long post. SO long it has to be broken in two. My reasons for being willing to spend the time may become more clear by the end . Question #1. The climate in the Jurassic WAS much warmer than it is today. While solar output was lower, the much higher levels of greenhouse gasses kept things warmer. Greenhouse gas levels are not the only factor in how warm the climate is, but they are one of the most important. Even at the poles conditions were temperate and there were no polar ice caps. Where temperate climates are today, conditions were tropical if wet, hot deserts if dry. Sea levels were higher. And life thrived, just like life also thrives (if less lush) under colder conditions during the post-ice age Holocene. But the very warm conditions in the Jurassic did not get that way in hundreds or even thousands of years, but millions. If we went from Jurassic climate to Holocine climate or vice versa in a few hundred years, life would be devastated. Most forms of life would die out due to not being adapted to the environment they found themselves in. Like a mammoth in the tropics. There would be drastic changes in sea level, large changes in ocean currents, drastic decreases in food availability as conditions settled into their new state. That first hundred thousand or so years would be brutal, especially as climate underwent the most rapid changes initially but before life started adapting and evolving. But in 10-15 million years, you'd need a paleontologist or molecular biologist (which is my scientific training) to know it ever even happened. Life would look just fine as though it had always been that way. The forms of life that survived the initial crash will radiate and speciate to fill the empty niches as they did after past mass extinctions. Which is why when people say we need to save the earth, they are wrong. The earth doesn't need saving, 10 to 15 million years is nothing on a geologic time scale. The point is that life can thrive under much higher CO2 levels, conditions under which plant life may be much more lush that today. We are actually in a relatively cold period. But a sudden (sudden meaning less than over hundreds of thousands of years) change from current conditions to Jurassic conditions will cause many if not most species of plants and animals to die out, and would devastate human populations,, produce a 100+ meters of sea level rise that would put our mostly coastal cities under water, and cause drastic reductions in our ability to produce food destroying moist cropland. The faster it happens and the larger the difference from start to end state the more damaging it will likely be. The issue isn't that there is a problem with life at a higher CO2 level but that the change to that state in a short time will be extremely difficult for animals that evolved in the past few hundred thousand years to adapt to and will devastating to us at worst, and be outrageously expensive at best in its effects a civilization used to the relative stability of the past 10,000 years. And when we burn fossil fuels we are releasing CO2 into the air that was there when CO2 levels were much higher and climate was much warmer and it pushing our climate in that direction . And we are doing it at a rate that is pretty much unprecedented as far as we can tell. It's less the end point that is the problem, but rather the difference between start and end climate and rate of change. And that's why life flourished when steady state CO2 levels were 5 times higher, but much more modest CO2 increases over decades to a few centuries are so concerning. Question #2 I haven't seen that claim, but if we are talking about a few degrees warmer than our planet TODAY, I would suspect that is a reasonable hypothesis. The reason is that we are actually in a cool period for the earth compared to its conditions over geologic history, and certainly plant life has been more abundant under somewhat warmer conditions. But we're back to BEING warmer vs GETTNG warmer. Being warmer isn't a problem, getting substantially warmer over human time scales is a big f#*!ing problem, Question #3. Global warming was the usual term used initially. Some skeptics mostly in the fossil fuel industry wanted to call it climate change because they thought it sounded less alarming and would be less effective in promoting change (turns out it doesn't have much if any effect on anything). It was a technically accurate term, although of the more general process of changing climate parameters. Anthropogenic global warming (AGW) being the specific driver of current rapid climate change. Some climatologists and many environmental activists objected to the change in terminology, mostly because people in the fossil fuel industry were advocating it and they certainly couldn't consider agreeing with them. But ultimately most climate scientists didn't have a big problem as it was still accurate language and doesn't really change anything. There is even the potential advantage that it might make it easier to reduce a public impression that global warming is just about hotter summers. But there is no connection between the strength (or weakness for that matter) of the evidence base regarding AGW and what terms were used. It's mostly about refusing to get drawn into a pointless battle over terminology. Question #4 +1°C to average temp doesn't seem like all that much. Average temperature is now about 1°C over preindustrial baseline (this was partially hidden by the effects of sulfate aerosol pollution unit recently). But would you also say 3.5°C isn't much? I mean it's the difference between 70°F and 76.3°F, and that's nothing. But it IS a lot for average temperature. It's the difference in average temps between the preindustrial baseline and when there was over a kilometer of glacial ice on top of what is now Boston. Just 3.5°C. Even +1°C to average means a lot of extra energy, about 5.95x10^21 joules (1.3 million megatons TNT equivalent) in the air and 5.3x10^24 Joules (1.3 billion megatons TNT equivalent) in the oceans. The heat makes seawater expand, has the capacity to drive greater jet stream oscillations driving extreme cold isn winter as the polar jet dips south, larger el nino/la nina events, and generally drive things to 11 on a previously 10 point scale. 1°C seems like it should barely matter, but it represents a huge increase in available energy to drive planetary cycles. end part 1

The scientists predictive models were deeply flawed. They did not consider the exponential effects of multiple tipping points. They underestimated the timing of severe change. The math and the science now shows clearly and unambiguously that abrupt exponential climate change is unraveling much faster and much sooner and with much more severity than predicted.

Germany is in the top ten for it's usage of "renewable energy", but still is the 6th highest emitter of CO2, in the world. Deforestation makes up to 25-29% of CO2 emissions, almost doubling that of transportation, but is never talked about as a cause for CO2 emissions. The geological devastation of land and animals would be 10 fold that of CO2 emissions, if we got rid of nuclear power and replaced with wind and solar, because of the land mass needed to produce the level of energy consumed.

He was a good astronomer, did legit PhD work, before he became a talk show host and public speaker. He does more good as a public speaker, so I'm not saying this as a critisism, but that's what climate change needs - a Neil deGrass Tyson to deliver their message. Michael Mann is boring. This lady, even though I agree with what she said, yes, she's not a compelling speaker, though I did enjoy her "would you give up your child story". But it shouldn't be too hard to find compelling speakers in the scientific community. When asked "are you an astrophysicist", Neil d'g Tyson can say "Yes I am", then he can continue his story.

So first they deny the realiy of ethics, and then they demand that we apply ethics to climate change. Good luck with that! Which is absurd. What material are numbers made of?

Affect is the critical word. Everyone underestimates the effect. Sea level rise is the worst example to give. The example to use is widespread starvation. The grain crops in central asia have already started to falter (cause of the Arab spring was food prices due to insufficient supply in asia). North America will feel it soon and see catastrophic crop failures every 3 years and a worsening of wildfires. Global economy will drop significantly instantly raising the temperature by at least 1 degree C (previous 1 degree rise took 20 years) due to reduced global dimming. At that point there will be no turning back. Feedback loops will take over. For those thinking we'll just do industrial farming in more northern latitudes.

To all that insanity, we add the fact that the IQ's of geologists and dozens of other fake professionals are uploaded - online - by Psychologists for all the world to see which means we are prompted to realize the 85 to 115 IQ's of geologists are the intellectual equivalent of the smart kids in fifth and sixth grades which then prompts us to realize the public is getting their history of Earth from those with the mind of a child - very few realize this and very few realize the true timeline for our Earth's continents, oceans, mountains, cataclysms, Earth's expansion and Earth's climate is documented by our ancestors in hundreds of historic documents who tell us the "scientific community" is a pack of insane imbeciles - so much for "peer review".

Heat energy travels through the air as infrared light. It does not interact with oxygen or nitrogen, but does with the heavier atmospheric molecules of carbon dioxide, methane and other such greenhouse gases that absorb and re-emit the infrared heat at the quantum level. This occurs innumerable times, thus delaying heat’s escape into space. This act of heat retention keeps our planet from freezing solid; however, increasing greenhouse gas density thickens the thermal blanket already insulating the planet.

Also fundamental aspects of adaptation will continue. The prediction of complete absence of ice is a Hollywood one and not common in the scientific community. Will seas continue to rise as they have for ten thousand years? Yes they will. Climatologists and Alarmists predict that most of the warming will happen closer to the poles as this follows the historical cycle. And indeed that is what appears to be happening. Growth zones expanding northward and southward are positive in food and habitat production and diversity will certainly expand in those areas. If sea rise forces migration it will likely be a very gradual occurrence and the human animal will continue to move to higher ground as it has since the last glacial event.

It is estimated that sea level rise of 10 metres occurred over a 20 year period in the PETM and we are warm the climate system MUCH faster. PETM carbon release was, according to a recent study, suggest a modest 0.2 gigatonnes per year (at peaks 0.58 gigatonnes); humans today add about 10 gigatonnes per year!

I think your estimates are high. Glaciers are very difficult to predict and we'd need a very rapid increase in glacial movement to get 2-5 meters in 10-30 years. It's possible, but it's unlikely. 2 meters by 2200 sounds wrong to me too, but it's pretty much impossible to predict glacial shifting. The IPCC tends to be conservative on sea level rise with a footnote that it could be quite a bit higher. 2 meters by 2200 would affect a lot of people, but you're right, it should come with an asterisk that it could be considerably more than that. 2 meters in 10-30 years, however . . . that's higher than any scientific estimate Ive seen, though Michael Mann says that 5-10 meter rises in 50 year periods are possible, but he doesn't say the next 50 years, he just says that rapid rise can happen.

Wind generators cost £1.4 million each. We have somewhere near 9400 turbines and would need a further 65000 to be self sufficient. Costs would be a further £90 billion.

At 76 I've experienced Climate Change turn into Climate Breakdown, In the UK I felt colder winters in my youth over decades that no longer exist. Hotter longer summers. In Greece, 74 to 84, the weather patterns that are traceable back through into Ancient Greek lit, in 75 from March into broken weather violent tropical rain storms never seen.The seas around Dawlish, my home town, are higher now then I ever saw before in my life. That goes with a disappearance of at least 90% of small birds and animals with a Massine lessening of fish catches. Then the pollutions! Apart from the reports from all around the world.

I don't doubt the veracity of your observations. However, you need to keep things in perspective. The Earth has gone through many ice ages followed by warming, all without human input. Thousands of years ago Greenland was covered with forest but you won't hear that from climate scientists/activists, because it doesn't fit their gloom and doom narrative. You should fact check me about Greenland if your in disbelief. Be safe and in good health.

@DE$CHAIN "the climate changing extremely rapidly." How do you know that? How do you know the climate didn't change rapidly in the past? Aren't you speculating the climate is changing faster today than in the past? What proof do you have?

@@tyronekim3506 there is a lot of evidence for this. If you cared about whatever sources I could link you, you would research it yourself

[@tyronekim3506]

@DE$CHAIN Don't do the cop-out. If you look at Earth's climate history there have been droughts and floods for millions of years. Even the Bible mentions floods and droughts. Who knew? Greenland used to be covered with forest thousands of years ago. Hundreds of years ago, you were crucified if you said the Earth was not the center of the universe. The Earth is coming out of the ice age. It has a long way to go to fully warm up. Do your own research.

imagine this space shuttles fuel to be burned every time it is launched The external tank held 143,000 gallons of liquid oxygen (1,359,000 pounds) and 383,000 gallons of liquid hydrogen (226,000 pounds). The fuel weighed almost 20 times more than the Shuttle. At launch, the Shuttle, external tank, solid rocket a prime global warmer isn't boosters and all the fuel combined had a total weight of 4.4 million pounds. is this the reason why the us exited the climate agreement? space exploration then is the main cause cause of global warming what's the benefit of these space exploration to humanity please educate me anyone :)

If we stop all carbon emissions and start massively NETs today : the sea level rise locked in is : +1m by 2100 +6m by 2100-2200 +1m 2200-2300 that is 8m total. I don't see the point in adapting to 1 meter if more meters are in the pipe. If you put billions into a sea wall you expect to serve at least one century, that is just non sense to adapt for 1 meter. Moving uphill is a way better solution. All those beautiful properties are future sea rectangles.

Alexandre Lollini, would you prefer to see a beach disappear or a whole continent.

[@kenvandeburgt1232]

The tide gauge data shows current sea level rise is 1 - 2mm per year and it has been averaging that ... with periods of rise and fall ... for the past 8000 years. The satellite record shows 3 mm per year ... and there are controversy about calibration. Even if you accept the 3 mm per year ... you get 24 cm by 2100 ... far short of 1 m by 2100. Where is the sea level rise going to come from? Antarctic is currently -60C and Greenland is -20C. Ice doesn't melt at those temperatures.

[@YTEdy]

I'd like to know where you get your numbers. There can't be a high level of certainty to what you propose. 2100 is maybe close, but even that, hard to say for sure. 2200 - too hard to say.

[@patricklincoln5942]

Spray the atmosphere near the poles with sulfates at the layers that wont destory the ozone layer to refreeze the arctic and antarctic. Then we will be o.k, (but only if we cut emissions too).

[@YTEdy]

Sulfates would spread, would cause acid rain, would hurt the Ozone. The sulfate method would also be temporary and need to be repeated, and thousands of tons of sulfates would probably be needed. That's a lot of cost and work. I don't want to call it impossible, but it's an extreme approach and a kind of last resort. In addition to expensive, it would be messy. Never say never, but nobody is seriously considering that approach today.

The climate is changing - always has, always will. There is nothing unusual or human-driven about any climate change we've observed over the past 1,000 years, with the exception of LOCAL and REGIONAL changes based on land use changes. Global and long term trends are still driven primarily by the sun, modulated by the oceans.

Very good presentation intended to make climate change relatable to the many people who are confused and put off by the idea. Imo it succeeded quite well. It"s sad that so many commenters seem to be so profoundly uncomfortable with the fact that emotions were included in the talk. Because the emotional level is exactly where people are having trouble grasping the reality of this phenomenon. Which, I'm sure is why Dr Mortsch presented it this way.

[@matthauslill4577]

This lady is not a scientist and does not even know what SCIENCE is. More and more ordinary people are fed up with these utterly boring sermons of believers in this artificial IPCC religion. We did not even reach the optimal global mean temperature of 15 degree C inspite of increase of CO2 concentration in the atmosphere. Hopefully it will warm up soon. We are coming from the little ice age and had 1850 the coldest temperatures and the biggest glaciers since 12 000 years! Sea levels are rising with the same 2-3 mm as for centuries - not even noticeable and there will be no big change. The IPCC uses housewives to present their Scientific fraud.

Suppose Climate Activists are correct. Then the total carbon budget for the Earth means all countries, including China, India, Indonesia, and other third-world countries need to also massively reduce their carbon production. Not just United States, Europe, and other 'first-world' countries. There is a brutal, cold truth that these Activists are not willing to confess. There are too many people, who need too much energy, and any level of civilization that would approach modern 'first-world' conditions would require a population under about 1.0-1.5B people. And even at that level of population, energy usage would need to be drastically reduced from the current high levels of consumption. The alternative is (nearly) everyone would need to live on an energy budget far below 2KWhr per day - which means basically forget refrigeration, heating, air conditioning, transportation, modern medicine, et al. Which means massive starvation and disease (and a massive die-off beyond anything anyone can imagine). Which elites get to decide which people are allowed to live in their "Brave, New World"? Certainly the wealthy and politically well-connected expect their "place". They are all hypocrites, flying from conference to conference, driving large SUVs, because they are privileged. Has anyone studied history, has everyone forgotten the lessons of the early 20th Century?
