Well, of course climate change is happening. The only constant about climate is change
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)
Well, of course climate change is happening. The only constant about climate is change. It changes all the time. If it didn’t, we would still be stuck in the last glacial period when the Laurentide Ice Sheet covered most of Canada and reached as far south as present-day Illinois, Ohio, and New York. Thank God there is climate change.
If it were true that “the greenhouse gases emitted by human activities are the primary driver,” it still wouldn’t make any difference since the primary driver of a small change, namely a 1.1-degree Celsius warming since 1880, is unimportant from a policy perspective.
American Association for the Advancement of Science (AAAS):
"Based on well-established evidence, about 97% of climate scientists have concluded that human-caused climate change is happening." (2014)
Well, duh, of course it is happening. Witness the urban heat island effect where it is warmer in cities than in the countryside. But, unless “human-caused climate change” is a serious problem, there are no policy implications of the AAAS statement.
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)”
Again, so what? (for the reasons discussed above).
American Geophysical Union (AGU):
"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 alternative explanation supported by convincing evidence." (2019)
