    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)

    So, more Co2 and methane in the atmosphere and the earth, on AVERAGE, gets warmer. This causes more trees to grow at higher latitudes and they trap more Co2. Overall humidity worldwide will be up, bringing more moisture to the desert areas causing them to grow more plant life, and therefore trapping even more carbon. Again, overall the AVERAGE ocean temperatures will rise allowing the growth of corals and other marine animals further north and south into the arctic zones, again trapping more carbon. Now, did we point out that over the last 10k years the earth was in a cooling trend heading to another glacial maximum? The current trend in rising Co2 levels and rising temperatures started about 7000 years ago with the advent of slash and burn agriculture, and increased again about 5000 years ago with the onset of domestication of animals, but rapidly increased in the early 1980s with the industrialization of China, effectively ending the Milankovitch cycle. We're all not going to die with global warming, it's just going to be a warmer as we return to the average temperatures as recorded over the last 50 million years. Sea levels will also rise back towards the average sea level recorded over the last 50 million years. And, oh yes, Co2 levels will rise back towards the AVERAGE levels that have been recorded over the last 50 million years or so. It's not the end of the world, just another change in the long chain of changes.

    Something that most native populations around the globe, with no fancy science attached, nor needed already know...
    humans CANNOT and NEVER WILL, be able to, control the Earth!
    Change is evident in all things-
    comes with time and other change which force change (reaction) to that which has changed (action).
    Its a natural balance with no reason to over think, only to accept and just be.

    Interesting how many people mandate that the world remains in its current form when the world has never had a static environment. It has always changed, and each species has had its effect on the environment, but humans effect on the Earth is considered not natural? I suspect that nature has allowed humans to multiply in the numbers it has because nature is using man to get to the next stage of evolution. Regardless, whatever man does to justify its existence will become part of natures purpose for this magnificent planet. Isn't life exciting?

      @heskey333 .......do you honestly believe a trace gas with a concentration of 1 molecule for every 2500 molecules of O2 and N2 is heating those 2500 molecules on average. Now bring into the equation the oceans, which have a specific heat of 200% that of CO2. This means is takes twice as much energy to raise water 1 degree per unit mass as CO2.
      If CO2 is heating the atmosphere and the oceans, which is ludicrous, then I want to know how to heat 2500 homes in the winter from just 1 home..........this would be the scientific breakthrough of the century. So please explain how do it based on your beliefs.

    CARBON DIOXIDE.DOES.NOT.DRIVE.CLIMATE. WILL YOU GET THAT IN YOUR THICK SKULLS.
    The climb in CO2 is due to the oceans warming. The CO2 is released AFTER the oceans warm. The oceans warm AFTER the atmosphere warms. The atmosphere warms when the land warms and the SUN warms the land. Climate is driven BY THE SUN.

    It is very simple. It is normal period of cold and heat. Now, since the industrial evolution, we've been putting way way too much carbon in the atmosphere, so what that means is that intervals of cold and heat will be shorter. Nothing else. But we are just at the beginning. It will take 10 of thousands of years to change things for the worse where it could affect us in any bad way.

  • Dean PD

    0.7 degree increase in temps over the last 100 years? If this bloke is a climate scientist then he is at odds with Professor Andy Pittman, a climate scientist here in Sydney who told me that the increase is 1 degree over the last hunjee years. I thought 97% of climate scientists agreed? ...so coral all but disappeared during that extreme heating event? Interesting that coral was able to bounce back because apparently, we are facing corals extinction. ...How wonderful that the planet got greener during the Paleocene/ Eocene? You'd think that greenies would be happy to see more green? Or maybe they just really want to see more red of the communist type? Imagine going for a swim in the Antarctic and seeing all that wild landscape down there go green? We are told that we are on the verge of the death of existence yet this period produced much more life than it ended...why we even saw the beginning of primates! Me think it mazing. Seems like we will all have to do something really scary...like adapt. Now there's a novel idea that life on earth has never thought of before. ...wonder how much life there was on the planet when the whole planet was a snowball?

      @Don Fields - Thank you very much for your rely. So many people simply don't understand how the planet works even after listening and reading to what the science community is telling them.

Also, the politicians on the planet are not helping by denying that Global Warming is happening.

    • Don Fields
      Don Fields 9 days ago +3

      Methane first heats the atmosphere and water, land etc, methane turns into c02 and gulp gulp says the ocean thus the ocean acidifies.

    Soo, back then more CO2 was released because it got hot. That does not necessarily mean the CO2 we emit today will cause it to get hotter. It depends on your assumptions, and this example does nothing to inform those assumptions.

      @swdhj ok i see where your coming from there, and they didnt explain this in the video, skepticalscience.com/empirical-evidence-for-co2-enhanced-greenhouse-effect-intermediate.htm

      It's like this, CO2 is a better insulator, heat passes through nitrogen and oxygen easier than through CO2, on a hot day, you go to the beach, the sand is hot and burns your feet but the boardwalk is much cooler, wood absorbs less heat than sand, same with CO2 as compaired to O2, CO2 would make a better "blanket" if you were trying to keep warm

    • swdhj
      swdhj 12 days ago

      @John g I am just trying to understand the logic here. The logic in this video is: suppose you have a lake with geese. Years ago, before humans, there were many more geese, and as a result, there was more goose poop around the lake. Today, humans dump a truckload of goose poop by the lake. But that exogenous poop does not cause more geese to be at the lake. So yes, when it was warmer, there was more CO2 in the atmosphere, but the above example cannot inform the "feedback" of the magnitude or sensitivity of CO2 on warming.

    Bring on the warming. More rainfall and longer growing seasons can't be bad. "Climate Scientist's" predictions only consistent feature is their near-universal failure to come true.

      Vast majority of scientists for the last century: the planet is warming
      Scientists whose preliminary work suggested cooling: With a proper study, yeah it's warming
      All data on climate trends from multiple competing sources and various lines of evidence: warming
      Climate without human activity: cooling
      Climate with human activity: warming

    Only someone who is totally unaware of global climatic conditions can believe that ‘climate change’ is not real, and thinking that the ‘rate of change’ in the global conditions is natural indicates a lack of knowledge that is unfortunate. For some, this is a simple lack of knowledge, while for others, it’s an act of willful ignorance engendered by fear. Now that is something I can understand. Global warming IS insanely scary!

    I think we should invest in this beautiful planet of ours that we abuse and take for granted instead of spending billions looking at other planets. We have too many problems on earth, so I think we should concentrate our efforts trying to sort all these problems out. Every animal & insect is needed to keep the planet in harmony and its only humans that are not needed to keep the earth balanced. Humans ruin nearly everything we touch, so we should put right everything we've screwed up.

  • Ultimate Classic

    There's also the Permian extinction event which killed off 96 percent of all life on Earth, majority of life was killed off in the oceans due to the vast release of methane hydrates creating a positive feedback loop. The widely accepted theory is that the Siberian traps, a major volcanic environment, raised the Earth's temperatures to very high levels, causing the oceans to warm, which depleted oxygen levels, killing life and releasing the hydrates which killed more life. The global temperatures reached 10 degrees or higher.
    What's disturbing is that global temperatures will reach at least 3-4 degrees by the end of the century if we don't do anything to curb CO2 emissions. 4 degrees might be all that's needed to release the methane hydrates. 50-100 years after this century ends the greenhouse effect will be runaway and the next extinction event will quickly annihilate us and most of life on Earth.

If only we could look back into history at the Maunder, Dalton, Wolf, Sporer Minimum. Maybe people would realize that the Minimums were the start of the collapse of complex societies.

    • Lonely Pizza Slice
      Lonely Pizza Slice 16 days ago +1

      Thats kinda what scientists are trying to figure out; from what I've seen most believe that its caused by a large expanse of plant life dying out and trapping their CO2 (the video showed an example of this). But i'd love to know of any other hypotheses that exist.

  • Peter Staples

    If C02 is at rate 5 times faster now than at the PETM and over the last 100 years the temperature rise of less than 1 degree C is in the variability rise of natural warming one would assume that C02 has very little to do with warming of the planet.

    The solution is to do the things that caused global cooling in the 1960's according to the scientists who wrote the alarming Time Magazine articles on the cool temperatures, where it was predicted we were only decades away from a new ice age. The only problem: Those are exactly the same behaviors that scientists claim now cause global warming.

      99% of all species to develop on the Earth have already become extinct. Pollution and waste are far more pressing problems than the made up one of "global warming". All life on the planet benefits greatly from lots of CO2, all life on the planet suffers from reductions in CO2, basic biology. You want to kill off all life on Earth? Get rid of CO2 from the atmosphere

      Except the supervolcano is just hypothetical. Human induced climate change is a given. The presenter glanced but didn't elaborate on another important fact: We're causing the temp change rapidly which gives virtually no time for us or other organisms to adapt. PETM took thousands of years... enough for our predecessors to evolve significantly.

    Gabriel Velasco 19 days ago +3

    The most biologically productive eras in Earth's history have been when it was warm with lots of CO2 in the atmosphere. CO2 is a fertilizer for plants and they do better in warmth than in cold. Lots of plants means lots of plant eaters. There was a time when the Earth could support HERDS of GIANT herbivores. It can't do that now because there's not enough CO2 and heat to grow enough food to support them.

    I'm curious as to how the CO2 today and the PETM? Can one explain this? I mean, in both cases we have an increase in CO2, but the increase is higher now. We don't know what caused the increase in CO2 back in the PETM, we do know now. We assume in both cases that the rise in CO2 is the cause for temperature rise. Are we seeing the same rise of temperature regarding the same amount of CO2? Is there something different?

    Dude your talking crap. Up less than a degree in a hundred years. Then you say “perhaps”, and I’ll state no perhaps because the models are a hypothetical model that that is based on guessing parameters and only the doomsday crap is kept. In 1989 chicken little screaming as Al Gored that by the year 2k. The ice caps be gone and sea level up 30 meters. In reality up maybe 1/2”. and talking about ancient ice ages and warming period. Man didn’t cause that. Blind leading the sightless.
