    That's the attitude that'll get people to change their mind!!

    Rhetoric like that will just cause people to dig in their heels more.

Look how long it took for the earth to recover from that and the ice to recede. We're warming way faster now than we did then. Thank you for proving my point and also confirming this is, in fact unprecedented.

    Definitely not lying about the costs of a 100% renewable non carbon energy system.

    Rolling your eyes at the back of your empty head?? All of these ice ages were caused by extreme events, including the one that killed the dinosaurs. What, 60 million years ago. The freezing is usually pretty quick, months.. the thawing takes MILLIONS of years... until now..

    The Pleistocene Epoch is typically defined as the time period that began about 2.6 million years ago and lasted until about 11,700 years ago. The most recent Ice Age occurred then, as glaciers covered huge parts of the planet Earth.

    8. Methane, Nitrous Oxide, CFC Fluorinated gases, HFCs.

    Methane has 28 times the global warming potential as CO2. Nitrous Oxides are 265 times CO2. CFCs are even worse with Sulfur Hexaflouride having 23,500 times the global warming potential as CO2. HFCs are referred to as “super greenhouse gases.”

    Despite being in very low concentrations, these gases are trapping heat in the Earth’s atmosphere. It's physics. We know that greenhouse gases are changing the atmosphere. These are physical facts.

    We are at present in the early stages of what will become a much larger CO2, CH4, N2O, CFC, HFC experiment.

    Nope. "The causes of ice ages are not fully understood for either the large-scale ice age periods or the smaller ebb and flow of glacial–interglacial periods within an ice age. The consensus is that several factors are important: atmospheric composition, such as the concentrations of carbon dioxide and methane (the specific levels of the previously mentioned gases are now able to be seen with the new ice core samples from EPICA Dome C in Antarctica over the past 800,000 years); changes in the earth's orbit around the Sun known as Milankovitch cycles; the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the earth's surface, which affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth–Moon system; the impact of relatively large meteorites and volcanism including eruptions of supervolcanoes." https://en.wikipedia.org/wiki/Ice_age

    Earth’s ice ages are thought to be caused by the wobbling of the planet’s orbit changing its orientation to the sun and causing more or less sunlight to hit higher latitudes, especially the polar regions. Under the right conditions as the earth warms up more CO2 is released into the atmosphere which explains, in part, why CO2 sometimes appears to lag a warming trend. The opposite happens, the planet cools, if atmospheric carbon dioxide is low enough and polar regions receive less sunlight.

    What we've seen from past global temperature reconstructions is the warming and cooling is not uniform across time and space for the planet. Sometimes Antarctica begins warming or cooling for thousands of years before northern latitudes like Greenland do the same, and vice versa.


    The late 20th century stands out, however. In the most recent decades, record-high temperatures are found simultaneously over almost the entire globe. In contrast there is no evidence for globally coherent warm and cold periods over the preindustrial Common Era.


    And those findings are based on 700 climate records in an open-access database. The come from glacial ice, ocean sediments, tree rings, corals and other sources. The resource allows scientists to recreate wide snapshots of global climate that would have been extremely difficult just a few short years ago.

    People have already made feeble attempts at rebutting this latest research (2019) by presenting selectively chosen graphs – each presented in isolation – and then claiming that as proof even though those climate records are also included the open-access database.

    Back to extreme and catastrophic events causing the large scale climate changes.. Everything else is well over the 50-100 years this shift has taken.. What's the large scale event causing the warming this century?? Best you can do is show a chart with THOUSANDS of years in 50s and 100s increments? Gotta do better than that LOL

    A quick note, your chart(s) sometimes give the impression that past warming/cooling events were global, occurring at the same pace and highly correlated. But that's not necessarily what we see in the records:

    You keep stating this as fact based on one study which has only been out for a month. We have a number of other studies that I have shown you in another post that do not agree with the conclusions of that study.

    Nope. You presented a webpage with selectively chosen graphs – each presented in isolation – which is hardly a rebuttal.


    And it's not just the Neukom paper[1] suggesting the late 20th century stands out (for the most recent decades, record-high temperatures are found simultaneously over almost the entire globe).

    Another recent (2019) paper[2] suggests the 20th century, not unexpectedly, is unique during the common era: it has the largest global-mean warming trends over periods of at least 20 years.


    Both studies show that the warmest period of the last 2,000 years was most likely in the 20th century. They also show that this was the case for more than 98 percent of the surface of the earth. This shows – once again – that modern climate change cannot be explained by random fluctuations, but by anthropogenic emissions of CO2 and other greenhouse gases.

    What we didn’t know until now is that not only average global temperatures in the 20th century are higher than ever before in at least 2,000 years, but also that a warming period is now affecting the whole planet at the same time for the first time. And the speed of global warming has never been as high as it is today.

    Science and Environmental Communication on YouTube: Strategically Distorted Communications in Online Videos on Climate Change and Climate Engineering

    ‘A toxic mix’
    YouTube isn’t the only online platform where climate denial is rampant. There are numerous blogs, Facebook groups, Twitter accounts, and thinktank websites spreading misinformation about climate change, its impact, and solutions.

    “We know that polluting interests and state actors like Russia (one of the countries likely to profit from climate change) are involved in creating troll farms and bots whose sole purpose is to promote climate change disinformation and denial and foment online discord and conflict,” said Michael E. Mann, director, Earth System Science Center at the Pennsylvania State University, US, in an email to ThePrint.

    “How much of the climate denial noise we see is due to that, and how much is due to misguided individuals taken in by this misinformation is hard to say,” he added. “But the simple answer: It’s a toxic mix of both.”

    Climate deniers project warming as a matter of debate despite the fact that scientists have unequivocally established through long-term data records and analysis that the Earth is indeed warming at an unprecedented rate because of human activity.

    A survey of over 12,000 peer-reviewed climate science papers found a 97 per cent consensus that humans are causing climate change by emitting carbon dioxide and other greenhouse gases into the atmosphere primarily through the burning of fossil fuels.
    https://www.frontiersin.org/articles...019.00036/full
    Scientists now have decisive molecular evidence that humans and chimpanzees once had a common momma and that this lineage had previously split from monkeys.

    Things like the Milankovitch cycle, solar output, and earth-moon orbit are not considered extreme events. The Milankovitch cycle is believed to be responsible for the very large ice ages you see every ~100k years: https://www.sciencedaily.com/release...0807134127.htm

    There is no large scale event causing the warming this century. I've already told you a half degree warming in 60 years is not abnormal.

    My chart with a timescale in thousands of years is there to show you that it doesn't take "millions of years to thaw out of an ice age."

    EPICA is a Greenland ice core. Vostok is an Antarctic ice core. Notice the time scale. When we go back hundreds of thousands of years we don't have a lot of good options for proxies. Here's a deep sea sediment proxy which correlates well with the ice cores: Click image for larger version.

    No, each of those graphs are from separate studies.

    I'm highly skeptical of a paper that tacks on our most accurate temperature recordings (instrumental record of the past 150 years) to a historical record of hundreds of poorer temperature recordings (proxies). Averaging hundreds of proxies is bound to smooth out past temperatures. To compare that to modern temperatures they should be averaging the same proxies, not using the instrumental record of recent years.

    You have continuously presented Greenland's GISP2 – in particular Easterbrook's misrepresentation – as a proxy to conflate Greenland with past worldwide global climate conditions.

    But that's not even true with Greenland as a whole. For example, DYE-3 in southern Greenland indicates a Holocene warming trend while Renland and Agassiz in central and northern Greenland show a cooling trend over similar time frames. Other sites in Greenland show warming and cooling that occurs at different times and are nonsynchronous.

    And that's just Greenland in the North Atlantic where a person might expect temperatures to correlate, and yet they often have different inflection points occurring at different times.

    If I've used GISP2 as a proxy for worldwide temperatures then that would be a mistake, but I believe I have been using it specifically in relation to Greenland, or to show how quickly temperatures have spiked in the past. It is the highest resolution we have for Greenland ice cores looking at the past 20,000 years. Is there any source other than skepticalscience that claims Easterbrook messed up the timescale of the graph? You would think with how much use the GISP2 data gets there would be more than a skepticalscience post on it.

    It is alarming the differences in the various ice cores for Greenland alone, although the majority show the Holocene to be trending colder. Perhaps our temperature records aren't especially reliable?
