Greenhouse gases reach record highs
1d
The World Meteorological Organization said atmospheric levels of carbon dioxide, methane and nitrous oxide rose to record highs in 2025, extending a warming trend.

The growth in global greenhouse gas emissions has slowed, from 1.7%/year from 1990-2015 to 0.8%/year from 2016-2025.
Nevertheless, global GHG emissions are still at record high levels. Progress?

Greenhouse gas levels hit new record highs, locking in more long-term temperature increase.
The intensifying El Niño may lead to a further surge.

Why did GHG emissions rise in 2025?
The biggest increase was in the USA, followed by international transportation. India, Russia, & the European Union all had slight declines.
Chinese GHG emissions rose, still not peaked.

🚨 The UNs Emissions Gap Report 2026 explains the dire realities of our current emissions trajectory: we have overshot 1.5 degrees and, at this point, the 'lowest possible' overshoot scenario involves limiting peak warming to 1.7 to 1.8°C.: www.unep.org/en/news-and-...

There are many interesting stories at the country level.
The EU is the only major region with sustained reductions, the US reductions are slowing. Despite clean energy, still strong growth in China & India.
Russia has higher per capita emissions than the US!

There is hope in the elections taking place around the world and how they may usher in new leadership in many countries. Even with those changes, we all are in for a warm ride filled with climate shocks until we stabilize the concentrations of greenhouse gases in the atmosphere.

New data confirm carbon capture & direct air capture are useless opportunity costs
At the capture rate (0.59 MTCO2/y) from new CC/DAC in 2026 where the CO2 isn't used for EOR, it will take 81,000y to build enough CC/DAC to capture the current CO2 emis from fossils & land-use change (47,200 MTCO2/y)

We have come to the point in the year (ie the weeks before the climate negotiations begin) when everyone releases their state-of-the-planet reports. This year, the perspective is overwhelmingly bad:

September data for HadCRUT global temperature now available. 2026 (based on Jan-Sep) best estimate is second warmest in this record, but uncertainties overlap with all of 2023-2025 to some extent.
