Some people are mis-using IPCC Table 12.12 to falsely claim that the latest IPCC assessment is that most types of extreme weather have not increased. Thread to explain why they're wrong.

How much carbon budget do we have left if we want to stay below 1.5˚C?
Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C.

Many important weather and climate data streams have gone silent as the U.S. government shutdown continues on.
As just one example, NOAA’s Global Monitoring Laboratory did not release its regular monthly update for greenhouse gases, such as for carbon dioxide, methane, and nitrous oxide.

Interesting study from researchers at UCL on how wind power has held down energy costs in the long term.
The key argument is that it has lowered gas prices in Europe by reducing demand for gas. And actually most of the savings are on gas, not electricity bills
