<span style="font-size:12.0pt">1. PM 2.5 is a fine particulate air pollutant from burning fossil fuels and from forest fires which can cause serious health problems even from short exposure. It is responsible for 3.7 million premature deaths a year. The Trump
administrations is moving</span> <span style="font-size:12.0pt">severely to limit scientific study of this or any other public health menace. Thanks to Ed Brock for the news.

<span style="font-size:12.0pt">2. As we cease burning fossil fuels we will release less particulates to the atmosphere. Since particulates promote cloud formation, they cool the earth; the effect is called global dimming. Their absence will allow faster heating.
A new measurement indicates that the cooling effect is twice as large as we had thought.

<span style="font-size:12.0pt">3. In some of Trump’s comments he doesn’t indicate that he understands what the climate crisis is, much less what is causing it. He confuses climate issues with the concerns of popular 1970s environmentalism: general air pollution
and the ozone hole. Some right-wing propaganda attempts to confuse people in this way. It is not clear whether Trump is a propagandist or among the propagandized.<span style="mso-spacerun:yes">

<span style="font-size:12.0pt">6. A couple of short videos help us begin to comprehend a perspective of climate changes which can produce effects lasting for hundreds of thousands of years—perhaps longer than our species has been around. The Paleocene-Eocene
Thermal Maximum, PETM, about 56 million years ago, provides the closest historical analogue to the changes we are working in our climate system.

<span style="font-size:12.0pt">7. Early climate models from the 1970s through 2001 have been surprisingly accurate in predicting the heating which has occurred since then. For 10 of the 14 models studied, “there was no statistically significant difference between
their output and historic observations.” The study encourages trust in the forecasts of current models.
