no, collective elvoution has been quite conservative

@1patriot Does it agree with accepted science?

@Pand0ro no and how much science is settled....most ceritainly not global warming

@1patriot Global warming is a fact. What is causing it is debatable. Certainly adding carbon dioxide to the atmosphere has some affect. Again. how much is debatable. Hot button issues like global warming become political, which has no place in science. In order for supporters to get their point across, they magnify the problems and push the worst case scenario, which is at the best dishonest and does nothing to identify conditions.

@Pand0ro you have taken the coolaid on the global warming debate you will need to educate your self i have spent 40 years on it! i don't blame you as the media sell the bullshit every day! carbon dioxide we need and it at the lowest level we have in the history of this planet! we even at it to our green houses!

@1patriot We add it to our greenhouses because plants use it to build carbohydrates. One of the waste products of that reaction is oxygen. I am a skeptic as all people should be. Skeptics test ideas against known facts and the facts say we are warming globally. We need to cut out the political hype from both sides to get an a more consistent understanding.

@Pand0ro show your articles that prove we are warming fast as we are warming but it's been thousand of years warming not years cause if your getting info from TED, Greenpeace, World Wildlife Fund, Amnesty International, Doctors Without Borders, Oxfam these are activist organization and the information can not be trusted.....FACT: The HadCRUT4 surface temperature index, produced by the Hadley Centre of the UK Met Office and the Climate Research Unit of the University of East Anglia, shows warming to 1878, cooling to 1911, warming to 1941, cooling to 1964, then warming. The warming rate from 1908 to 1938 of 0.13 ºC/decade was almost as large as the recent warming from 1983 to 2013 of 0.17 ºC/decade, each 30-years, despite the CO2 increase of the latter period was 4.7 times greater than the former period. Satellite data show cooling from 2002 through mid 2015, then this warming pause ended with a large El Nino event starting late 2015. The UAH analysis of satellite data gives a trend from 1979 to Aug. 2020 of 0.14 ºC/decade, which is half of the corresponding trend of 0.27 ºC/decade of the climate models. The mild warming of about 0.7 ºC over the 20th century is well within the natural variations recorded in the last millennium. The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands" ), which show substantially higher readings than adjacent rural areas ("land use effects" ). Two science teams have shown that correcting the surface temperature record for the effects of urban development would reduce the reported warming trend over land from 1980 by half.

There has been no catastrophic warming recorded.
