  1. I'm not that confident that the genZ-ers are gonna change anything, simply because there is no real democracy anywhere in the world- the only goal of every government is to keep capital safe. There are a lot of quite young billionaires who still have many years to go ahead, Zuckenberg, Musk, Altman, the Saudi prince is only 38…The old ones also have their children who are going to try everything to protect their wealth…
    I love the cat btw ❤

  2. I've read in an article that if the temperature rises by 2.8 degrees, there will be a food crisis and the possibility of world war will increase.
    The other day, I watched a video by NASA that visualized the increase in atmospheric CO2 in chronological order.
    This video made it clear that in the Northern Hemisphere, where many industrialized countries are located, CO2 is gradually flowing to the North Pole, and that the temperature rise in the Arctic Circle is greater than in other regions.
    I may be wrong, but since the Arctic Circle has midnight sun, it must have been affected by CO2 for a long time, causing the permafrost in Siberia to thaw, accelerating global warming.
    At the latitudes of the Arctic and Antarctic, the distance that sunlight travels through the atmosphere is longer, and warming increases proportionately.
    We need to conserve energy and reduce CO2 emissions, even if just a little.

  3. The only thing consistent about the baby boomers approach to climate change since Carl Sagan testified in congress in 1985 is that we keep making it worse faster than models could expect.

  4. For greedy exploiters. Let's see if it will be possible to drink oil instead of water. In one part of the earth Everything sinks under the Waters in another part everything becomes a desert… Maybe we can eat Money and Gold!!

  5. Now, in the climate establishment, you know, saying that all the models are warming too much and that there is not a disaster arising causes great consternation because of the narrative that has been built over the last 30 years that we are supposed to be in a catastrophe and to come out and say, “Well, here’s the data, and the data show there is no catastrophe looming. We’re doing fine. The world is doing fine. Human life is thriving in places it’s allowed to. So what’s the problem here you’re trying to solve?”

  6. Any Scientist knows this is explained by a very early ecology concept "The Tragedy of Commons" and the churches that preach falsely. It's the The Dunning-Kruger effect

  7. She sounded like the most optimistic scientist I've heard in a long time.

    People will migrate at 3°? Lol
    I'm afraid it's going to be quite a bit worse than that.

    Still downplaying it once again. This silly talk will go on for just a few more years.

    Don't look up.

  8. People, just live out your lives and try to find joy and well being. The Earth has existed for 99,9% of it's existence without humans and it will go on after us..There is an inevitable ice age coming and it will happen no matter what you do…Just enjoy your lives and nevermind the coming chaos.

  9. IPCC's (Scenario A) modelled predictions are junk. Back in 1990 the IPCC predicted a warming of 0.30-0.34°C per decade. Of course we've only had about 0.1°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them. The attribution of all warming to human activity by the IPCC is junk science as well. Take AR5: that says all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative!!! So many scientists/politicians may have reached a consensus, but the science on which that has been built shows no such agreement.

  10. Man-made atmospheric C02 is a driver for temperature, it follows lock step with the carbon curve just like a shadow following you walking down the sidewalk. We can predict C02 levels based on an average 2.3% growth rate per year. It's an exponential equation, which means that temperatures are going to accelerate at least as fast as the carbon being dumped into the atmosphere.

    In less than twenty years I calculate. 500ppm of carbon. Assuming a strictly linear graph, I get 2.89 C. in that year 2042 with a 95% confidence interval. Simple linear regression y=mx +b, y (temp) = 0.017 x (carbon – 330.0 ) That temperature prediction should work with most carbon values from the last ten years.

    This is significantly greater than the predicted 2.5 deg. C. and it's coming 50 years earlier. And it's probably not going to be a straight line. Which suggests higher global temps faster than even this rate is forecasting. Humans and most marine life will go extinct at 3 deg. C.

  11. It's over! The die is cast. Because of reductions in S content of maritime fuels stratocumulus cloud formation over the TCZ has decreased markedly. This so called global dimming from aerosols was actually a larger contributor to a reduction in heat than anticipated. James Hansen got it right. We are careening towards a tripping of all tipping points before 2050. 3 C will hit before 2060 as the earth's heat imbalance is skyrocketing as is methane emissions from natural sources. We are screwed! Do you really think there is any possibility of slowing down this gigantic global economic engine? NO. Only nuclear war will slow it down fast enough to avoid ecological collapse. And solar and wind are not going to save us as we don't have the mining infrastructure or even the high yield ores left…we've used all the good stuff up. Consider we are using about 100 million barrels of oil PER DAY! Given current proven reserves of 1.4 trillion we use it all up in about 45 yrs. But demand is growing as we've added about 2 billion to the consumer class in less than 20 yrs. In less than 2 decades the cost of liquid fuels and natural gas will be far too high. We are headed for a train wreck economically and environmentally. Club of Rome predicted this more than 50 yrs ago. We are totally screwed…as Hansen has said the heat is in the pipeline. If we don't start cooling the Arctic rapidly we are finished. We need cooling equivalent to three Pinatubos per decade otherwise we lose our grain belts in the life of our children!

  12. going by the current rate of 0.3 degrees of warming per decade. 2100 at a baseline will be 3 degrees hotter. If warming accelerates, which it is, we are looking at much more warming than that. With ice melting there's less sunlight getting reflected, deforestation, methane from permafrost melt, its all going to lead to a very different global climate, many places on earth will become completely uninhabitable for humans.
