Repeat after me... there is no empirical evidence that CO2 causes climate changes. None, nada, zip.If you listen to it, you might learn something.Then when one of those guys shows up we can have an intelligent discussion.
We are in the middle of an ice age that began 2.7 million years ago.If you listen to it, you might learn something.Then when one of those guys shows up we can have an intelligent discussion.
The transition to a greenhouse planet was due to plate tectonics which isolated the polar regions from the warmer marine currents and the rise of the Himalayan mountains which altered weather circulation patterns and the rise of the Panama isthmus which altered ocean circulation patterns.If you listen to it, you might learn something.Then when one of those guys shows up we can have an intelligent discussion.
The planet is uniquely configured for bipolar glaciation. A configuration which has never existed before in the earth's history.If you listen to it, you might learn something.Then when one of those guys shows up we can have an intelligent discussion.
There is no empirical data, just eternally flawed computer models and back-slapping "peer review" dreck that have never ever been correct.Your reminder that science is self-correcting, based upon the accrual of empirical data, reminds us that the dogmatists who deny science are out of their depth.
I don't know who trained you to parrot that, but you might wish to acquire a megaphone and educate NOAA, among other institutions. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.Repeat after me... there is no empirical evidence that CO2 causes climate changes. None, nada, zip.
From 1850 to 2018, 440 ± 20 Pg C (1 Pg C = 10¹⁵ g C) were emitted as CO₂ from fossil fuel burning (Friedlingstein et al. 2019). For 2018 alone, global fossil fuel emissions reached 10 ± 0.5 Pg C yr−1 for the first time in history (Friedlingstein et al. 2019). About half of the CO₂ emitted since 1850 remains in the atmosphere. The rest of it has partially dissolved in the world’s oceans… . While the terrestrial biosphere is currently also a sink for fossil fuel CO₂, the cumulative emissions of CO₂ from land use changes such as deforestation cancel terrestrial uptake over the 1850–2018 period (Friedlingstein et al. 2019).

The southern polar region is more susceptible to extensive continental glaciation than the northern polar region because the southern polar region has a continent parked over it whereas the northern polar region has an ocean parked over it which is largely land locked.CO2 – the major cause of global warming

CO2 emissions are the major cause of global warming
Global warming is caused by the emission of greenhouse gases . 72% of the totally emitted greenhouse gases is carbon dioxide (CO2), 18% Methane and 9% Nitrous oxide (NOx).

Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. Fossil fuels like coal and oil contain carbon that plants pulled out of the atmosphere through photosynthesis over the span of many millions of years; we are returning that carbon to the atmosphere in just a few hundred years. According to State of the Climate in 2019 from NOAA and the American Meteorological Society,

Climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.
AMERICAN SCIENTIFIC SOCIETIES
Statement on Climate Change from 18 Scientific Associations"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)2
American Association for the Advancement of Science"Based on well-established evidence, about 97% of climate scientists have concluded that human-caused climate change is happening." (2014)3
American Chemical Society"The Earth’s climate is changing in response to increasing concentrations of greenhouse gases (GHGs) and particulate matter in the atmosphere, largely as the result of human activities." (2016-2019)4
American Geophysical Union"Based on extensive scientific evidence, it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century. There is no alterative explanation supported by convincing evidence." (2019)5
American Medical Association"Our AMA ... supports the findings of the Intergovernmental Panel on Climate Change’s fourth assessment report and concurs with the scientific consensus that the Earth is undergoing adverse global climate change and that anthropogenic contributions are significant." (2019)6
American Meteorological Society"Research has found a human influence on the climate of the past several decades ... The IPCC (2013), USGCRP (2017), and USGCRP (2018) indicate that it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-twentieth century." (2019)7
American Physical Society"Earth's changing climate is a critical issue and poses the risk of significant environmental, social and economic disruptions around the globe. While natural sources of climate variability are significant, multiple lines of evidence indicate that human influences have had an increasingly dominant effect on global climate warming observed since the mid-twentieth century." (2015)8
The Geological Society of America"The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2011), the Intergovernmental Panel on Climate Change (IPCC, 2013) and the U.S. Global Change Research Program (Melillo et al., 2014) that global climate has warmed in response to increasing concentrations of carbon dioxide (CO2) and other greenhouse gases ... Human activities (mainly greenhouse-gas emissions) are the dominant cause of the rapid warming since the middle 1900s (IPCC, 2013)." (2015)9
SCIENCE ACADEMIES
International Academies: Joint Statement"Climate change is real. There will always be uncertainty in understanding a system as complex as the world’s climate. However there is now strong evidence that significant global warming is occurring. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)." (2005, 11 international science academies)10
U.S. National Academy of Sciences"Scientists have known for some time, from multiple lines of evidence, that humans are changing Earth’s climate, primarily through greenhouse gas emissions."11
U.S. GOVERNMENT AGENCIES
U.S. Global Change Research Program"Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities." (2018, 13 U.S. government departments and agencies)12
INTERGOVERNMENTAL BODIES
Intergovernmental Panel on Climate Change“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.”13
“Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems.”14
