New national climate plans have barely moved the needle on limiting global warming. Yet there is hope.
According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

About 1500 of the approx. 2300 people that will have lost their lives across 12 European cities last week would still live, if it wasn't for our burning of oil, coal and gas. If we care about the right to life, we need to stop burning fossil fuels. www.imperial.ac.uk/grantham/pub...

The land use change (LULUCF) sector is pretty confusing, since it can be a source of emissions (deforestation, disturbances) as well as a source of removals (regrowth, management).
Including LULUCF can speed up, slow down, or change the overall dynamic of economy-wide emissions.

The EU has released its latest GHG emission inventory, with data up to 2023.
The good news, GHG emissions continue a downward trend, currently 37% below 1990 levels.
The bad news, a significant downward revision of land-use removals (LULUCF).

So the US was supposed to report its greenhouse gas emissions to the UNFCCC yesterday.
For the first time since 1997, it didn't.
This follows last week's revelation that Trump's EPA is stopping collection of GHG emission from 40 of 41 sectors

Trump’s EPA Plans to Stop Collecting Greenhouse Gas Emissions Data From Most Polluters
Climate experts expressed shock and dismay at the move. “It would be a bit like unplugging the equipment that monitors the vital signs of a patient that is critically ill,” one said.
