Scientist Stephen Hawking wants to find a way to convince people to stop voting for Trump, and to start listening to people like him again, to save the planet from climate change and national borders.

This is the most dangerous time for our planet

Stephen Hawking

We can’t go on ignoring inequality, because we have the means to destroy our world but not to escape it.

As a theoretical physicist based in Cambridge, I have lived my life in an extraordinarily privileged bubble. Cambridge is an unusual town, centred around one of the world’s great universities. Within that town, the scientific community that I became part of in my 20s is even more rarefied.

And within that scientific community, the small group of international theoretical physicists with whom…

James Hansen: We Have a Little More Time After All (Whew!)

By Robert Bradley Jr.

“Contrary to the impression favored by governments, the corner has not been turned toward declining emissions and GHG amounts…. Negative CO2 emissions, i. e., extraction of CO2 from the air, is now required.”

– James Hansen, “Young People’s Burden.” October 4, 2016.

“The ponderous response of the climate system also means that we don’t need to instantaneously reduce GHG amounts.”

– James Hansen, “We Hold Truths to be Self-Evident“ December 2,  2016.

What a difference a few months make!

Just in time for holiday season, and for the Trump Administration, the father of the climate alarm, formerly a climate scientist with NASA/GISS, and now a full-time scientist/activist, has ameliorated his grand climate alarm. The 10-year ultimatum announced in 2006, made more dire in 2009 and since, is now moderated.

This October, we were told…

Who will rid me of this junk science?

The latest attempt to prove that tornadoes are becoming more extreme:

ABSTRACT

Tornadoes and severe thunderstorms kill people and damage property every year. Estimated U.S. insured losses due to severe thunderstorms in the first half of 2016 were 8.5 billion USD. The largest U.S. impacts of tornadoes result from tornado outbreaks, which are sequences of tornadoes that occur in close succession. Here, using extreme value analysis, we find that the frequency of U.S. outbreaks with many tornadoes is increasing and is increasing faster for more extreme outbreaks. We model this behavior by extreme value distributions with parameters that are linear functions of time or of some indicators of multidecadal climatic variability. Extreme meteorological environments associated with severe thunderstorms show consistent upward trends, but the trends do not resemble those currently expected to result from global warming.
