Yesterday we reviewed a study published one year ago which concluded that the total loss of Arctic summer sea ice would result in a temperature increase equal to 0.19C, which will be added bit by bit to the annual average … Continue reading →

COP26 is now over with. Many publications have summarized the outcome in much the same manner, and I’m sure most readers are already familiar with this basic viewpoint. In short, some real progress, outweighed by too much disappointment. The progress … Continue reading →

Take a good look at the next two charts, and save them somewhere.  These are the new landmarks of climate history.  As explained in yesterday’s letter, the old ones are now obsolete, based on reconstruction of evidence made by a … Continue reading →

New research provides a significant reconstruction of global temperature increases since the last ice age.  This work does not appear to be controversial, and should set new standards from which to measure the progress of climate change.  There are three … Continue reading →

If you have not read yesterday’s letter please take the time to do so.  It provides a perfect example of what could be called compelling evidence, first of all, that precipitable water (PW) has a greenhouse effect, and that the … Continue reading →

Yesterday I summarized four significant reasons, all based on scientific research recently conducted but not yet recognized in climate models, for why near-term global temperatures can be expected to rise to levels considerably higher than the COP26 “goals” being talked … Continue reading →

The principal motivation behind my writing of these letters, which began over eight years ago, has simply been to discover and explain whatever I could about things most likely to be true, mainly based on the current state of scientific … Continue reading →

More map reading today. We want to know everything we can possibly learn about the formation and life cycle of atmospheric rivers (ARs). We know for sure that they originate as water vapor coming off the planetary surface in certain … Continue reading →

Today’s Weather Maps offer a fine example of what atmospheric rivers (ARs) can do when they find a way to carry their content of concentrated precipitable water (PW) into the heart of the polar region. These images will show you … Continue reading →

I have learned quite a bit about atmospheric rivers (ARs) in the last few days by perusing relevant studies. You have access to the same information through links in the letters. You should be able to understand the dangers that … Continue reading →
