It is the position of many scientists that the predictions being made by the United Nations in regards to catastrophic climate change are wrong. They do not claim, however, that climate change does not happen, and they do not claim that humanity has zero impact. What they assert is that humanity has far less of an impact than is thought, and that natural variations have far more to do with global warming and climate change than anything humans do.
These natural variations include cloud cover, Pacific weather patterns such as El Nino and La Nina, and also variations in the power of the sun. A new study predicts that in between the years 2020 and 2030 solar activity will fall by 60%; leading to low temperatures that have not been seen since “The Mini Ice Age” in 1645. During this period of history the River Thames actually froze over.
Should these predictions be accurate, it will be interesting to see what approach global warming alarmists take. Will they claim that humanity’s impact on the environment is somehow causing extreme cooling instead of warming, and they simply got the effect wrong? That would be a bold claim. Or will they instead say that the low temperatures do not matter, because humanity’s affect on the climate can still be increasing temperatures once the natural cold variations finish. To pursue such a claim, however, would be perilous for global warming alarmists. To assert that belief, alarmists would have to then admit that natural variation in climate change does happen, and thus admit what many scientists have been pointing out all along, that natural variation has far more to do with temperature than humans’ initiatives.
All we can do is to wait and see what happens with future temperatures, and global warming assertions.
