The Democrats and mainstream media are continuing their decades-long campaign to convince Americans that continued fossil fuel use is about to cause an irreversible climate catastrophe. This theme is now a central feature of the campaigns of every single Democratic presidential candidate.
We now know that the main driver of long-term climate change on earth over the past billion years has been the varying flux of cosmic rays penetrating the earth's atmosphere and creating cloud condensation nuclei (CCNs) in the troposphere. The CCNs in turn provide the starting point for forming the cloud cover that determines how much solar energy reaches the earth's surface versus being reflected off the white tops of the clouds back into space. These long-term climate changes are modulated to a lesser extent in the short-term — human lifetimes — by solar variability, such as sunspot activity and solar flares. When the sun is in one of its active periods, its magnetic activity reaches out into the solar system and deflects some of the inbound cosmic rays from penetrating earth's atmosphere. This in turn prevents CCNs from being formed, reducing cloud cover. With clearer skies, the earth heats up more than otherwise.
