Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

If finalized, the move would escalate the Trump administration’s efforts to claw back billions of dollars in climate grants awarded under President Biden.

A string of hashtags has appeared on social media platforms using disinformation and promoting conspiracy theories about climate change. This analysis of interaction with these hashtags shows that they were mainly promoted by accounts linked to oil interests in Gulf countries. It also showed that this interaction coincided with international and regional events related to the climate issues, and was at odds with the stated positions of these countries, which claim to abide by international climate agreements.

The Trump administration has asked NASA employees to draw up plans to end at least two major satellite missions, according to current and former NASA staffers. If the plans are carried out, one of the missions would be permanently terminated, because the satellite would burn up in the atmosphere.

  • European governments are taking steps to break their dependence on critical scientific data the US historically made freely available to the world
  • Data on sea-level rise and extreme weather events put at risk by cuts to National Oceanic Atmospheric Administration [NOAA]
  • Over the next two years the EU plans to expand its own European Marine Observation and Data Network which collects and hosts data on shipping routes, seabed habitats, marine litter and other concerns.
  • In addition, the EU is considering increasing its funding of the Argo program, a part of the Global Ocean Observing System which operates a global system of floats to monitor the world's oceans and track global warming, extreme weather events and sea-level rise.
  • Nordic countries met to coordinate data storage efforts with Norway setting aside $2 million to back up and store U.S. data to ensure stable access. The Danish Meteorological Institute in February started downloading historical U.S. climate data in case it is deleted by the U.S.
  • A range of other European countries initiated complementary programs.

  • The European Central Bank (ECB) is set to introduce what it calls a 'climate factor' when lending to banks against appropriate collateral in their short and long-term financing instruments.
  • This climate factor could reduce the value assigned to the assets pledged as collateral, thus protecting the Eurosystem against a potential decline in collateral value in the event of climate-related shocks.
  • The climate factor also raises the pressure on commercial banks to direct their funds towards 'greener' investments as the bloc seeks to reduce it carbon footprint.
  • The new measure will apply to marketable assets issued by non-financial corporations, taking effect in the second half of 2026.

Of the five stations they list in their table, the one which shows the most obvious acceleration (St. Petersburg) is the one they don’t show the graph of! Of course they didn’t find acceleration in U.S. tide gauge records, because they never looked for it. They only looked for what they wanted to see, and that’s all they found. If you do analyze sea level data (and I have), in light of the most recent data (from satellites and from tide gauges) acceleration is obvious, both for the U.S.A. and the globe as a whole.

President Trump and Republicans in Congress are eliminating federal incentives to buy electric vehicles, but carmakers need to keep selling and investing in them.
