    Imagine an enormous, lush rainforest teeming with life...in the Arctic. Well there was a time -- and not too long ago -- when the world warmed more than any human has ever seen. (So far)

              Too much hype. No one knows how active the sun was in the Eocene, and the Sun provides all the heat the Earth gets. No amt of greenhouse gasses can warm the planet, since the Earth doesn’t generate its own heat. All comes from the sun. The Solar flux is not constant, as the 11/22 yr sunspot cycle shows, and we seem to be in a Grand Solar minimum like last occurred 1645 - 1715, when the Earth was excessively cold. Should such a prolongued minimum occur now, it just might tip the climate into another Ice Age, since we do not know the cause of such events, nor how long they last.

                    Great clip. Glad I've found you. What I am most interested in now is looking at continental drift combined with climatology, planetary science, botany, etc. to get a better picture of how continental drift over hundreds of millions of years directly contributed to distribution of plants and animals around the world - which you do touch on here. Also, very interested in what the world was like when the sea levels were much lower and whether the sea rose bit by bit or by cataclysm. Looking forward to exploring this channel. Also, very interested in human migration.

                          The globe is currently at about 400 ppm in CO2, and has increased by only about 140 ppm since the start of the Industrial Revolution. 500,000 years ago CO2 was at about 2,000 ppm and the Earth was about 14 degrees hotter and life flourished. Even if we continued pumping massive CO2 into the atmosphere for the next 500 years Earth would absolutely habitable. In fact, it would be even more so than it is today. Global warming is not a problem, the politicization of science is the problem.

                              There won't be any. Change happening this quickly won't give life a chance to evolve. It takes thousands of years not decades. Everything will just die out because it can't evolve quick enough

                                So It's all so natural. Hotter climate/colder climate...species going extinct, or evolving. Changes constantly taking place. Warming/cooling. Extremes during certain periods of history. Just as you'd expect.

                                  Nothing natural about it--we have pushed the climate far outside normal cyclical variations:


                                  First, the problem under discussion isn’t generic “climate change,” it is man-made global warming and climate disruption. And speaking as a researcher studying this issue, the research is overwhelmingly clear that yes, humans burning fossil fuels is what caused the recent changes in the Earth's CO2 levels and temperatures--changes that go far outside the up-down-up-down-up-down natural variation that had been going on for 800,000 years.

                                  The last time the Earth warmed this rapidly, over 90% of life in the oceans and over 70% of life on land went extinct, including everything over 90 pounds. But this time, it’s US who has caused the rapid warming, so it’s our responsibility to take action to cool Earth back down.

                                  Overall, if you look across all the sciences and all the systems of the Earth, human activity is steadily destroying the Earth’s ability to support life, including human life. But I’ll leave out the toxic chemicals and micro-plastics in our beer, drinking water, food, bodies, and rainfall, and just focus on man-made global warming and climate disruption.

                                  Global CO2 levels hadn’t been above 300 ppm for 800,000 years until humans started burning fossil fuels, and as a result, global mean temperatures have been getting hotter and hotter. Globally, EIGHT of the warmest ten years since we began keeping records happening in the last ten years!

                                  July 2019 was the warmest month since they have been keeping records. Here are two illustrations of how global temps have been getting warmer:

                                  GLOBALLY, the 40s WERE warmer than the 1970s or other earlier decades, but since then, all hell started breaking loose, with the 80s being much warmer than any previous decade, the 90s being dramatically warmer than the 80s, the 2000s being warmer than any previous decade, and the 2010s so far beating all previous decades by a wide margin for warmest ever:

                                  https://en.wikipedia.org/wiki/Instrumental_temperature_record

                                  Here's how we know that burning fossil fuels and thus adding CO2 (and methane) to the atmosphere causes global warming and climate disruption. In 1827 Jean Baptiste Fourier first recognized the warming effect of greenhouse gases. In 1859, John Tyndall did the original research on the physical properties of CO2. In 1896, the first quantitative estimate of the effect of doubling atmospheric CO2 on the mean surface temperature of the Earth was made by Svante Arrhenius. In May, 1967, Journal of the Atmospheric Sciences "Thermal Equilibrium of the Atmosphere with a given Distribution of Relative Humidity." Manabe and Wetherald were the first to include all the main physical processes relevant to the problem, using a model that was no more complicated than necessary to achieve this. This led to much more realistic simulations and enabled the results to be explained in terms of processes which could be observed in the real world. Manabe and Wetherald made a number of other discoveries. First, the temperature of the stratosphere cooled markedly when carbon dioxide was doubled. This is the characteristic “fingerprint” of man-made global warming by burning fossil fuels: the troposphere warms and the stratosphere cools, with more thermal radiation at the wavelengths of CO2 and methane being kept in the lower atmosphere and less escaping into the stratosphere. So, let's look at the actual science on that.

                                  Try all three levels:

                                  CO2 is TIGHTLY correlated with global temps and lots of research shows adding CO2 leads to temp rise. https://www.theguardian.com/science/2012/apr/04/study-rising-co2-global-warming

                                  Of course, the effect goes the other way too, as the Earth warms, the permafrost melts, more methane is released, that warms the Earth even more, so even more CO2 and methane are released (It’s a feedback loop, but this time around, we got the destructive ball rolling by burning fossil fuels).

                                  In 1982, Exxon accurately predicted global warming
                                  https://skepticalscience.com/1982-exxon-accurate-prediction.html

                                  The predictions from climate scientists from the 1980s and even 1970s and ones from the IPCC have quite accurate, while the predictions of climate deniers like Lindzen were way off the mark.
                                  And various climate models have been quite accurate, especially when you factor in that they couldn't have predicted the 2008 global recession that slowed the world's economy and caused a dip in CO2 emissions.

                                  And here are multiple forms of evidence on the 97% consensus on man-made global warming
                                  https://skepticalscience.com/global-warming-scientific-consensus-intermediate.htm

                                  On a more basic level, when scientists have labeled a class of substances as "greenhouse" gases because they help hold heat from the sun in the atmosphere (Earth would be 59 degrees F cooler if now for those gases), isn't it pretty obvious that when humans start adding more of those gases to the atmosphere, things will get warmer? In physics, actions have consequences.

                                  At the moment, human-caused global warming and climate disruption (aided by chemical and plastic pollution and deforestation) are steadily pushing the point where ecosystems will collapse and human civilization and the human population will collapse with them. I wish it weren't true, but it is. However, there are hundreds of solutions for healing the ecosystems and cooling the planet back to a healthier temperature, but we need to be willing to take action.

                                  Take care.

                                                          Humans only contribute 3%. Co2 is released from the oceans after they warm. There’s some flaws here.

The collapse of ecosystems made them unable to support larger animals. And 60% of the global wheat crop is projected to be in jeopardy by 2100. Most people don't understand that this isn't like taking a vacation to somewhere that is warmer and more pleasant--we are talking about rapid and disruptive changes that collapse the web of life our own lives depend on.

                                                            And various climate models have been quite accurate, especially when you factor in that they couldn't have predicted the 2008 global recession that slowed the world's economy and caused a dip in CO2 emissions.

                                                            On a more basic level, when scientists have labeled a class of substances as "greenhouse" gases because they help hold heat from the sun in the atmosphere (Earth would be 59 degrees F cooler if now for those gases), isn't it pretty obvious that when humans start adding more of those gases to the atmosphere, things will get warmer? In physics, actions have consequences.

                                                            At the moment, human-caused global warming and climate disruption (aided by chemical and plastic pollution and deforestation) are steadily pushing the point where ecosystems will collapse and human civilization and the human population will collapse with them. I wish it weren't true, but it is. However, there are hundreds of solutions for healing the ecosystems and cooling the planet back to a healthier temperature, but we need to be willing to take action.

                                                            Take care.

The CO2 emissions of the United States have gone down while economic prosperity has risen. So the United States is doing our part. Countries like China , which is the largest emitter of CO2 and has been since 2012, should use United States standards. India should as well. Also China is the world's largest polluter of the ocean. Hemp should be used to make biodegradable products. If this would happen there would be no need to ban coal, gas or oil.

Sometimes I do really believe that Earth can recover once human activities suddenly disappeared on one day. Imagine a dry land where an entire forest is cut down, nature will repair itself. But damn I have to admit, a tropical Earth seems to be better then cold and warm seasons in the Arctic circle.
