Clearer skies may be accelerating global warming

CEDS is a peer-reviewed bottom up estimate of global emissions, & in a process-based sense, is the most robust (whether it is more accurate is hard to tell given uncertainties & poor data to verify).

Here is a comparison with the latest CEDS data and the SSP scenarios.

There has been a long term decline in SO2 emissions, potentially causing an acceleration in global warming.

Since 2020, ships have had stringent regulations on SO2 emissions, accelerating SO2 reductions.

But how much have SO2 emissions dropped since 2020?

A major part of the increase in Earth's energy imbalance observed during the period 2001-2019 can be attributed to a reduction in #anthropogenic aerosol #emissions .

📈BREAKING 📈

The most important NASA graph in the world confirms increased Earth's Energy Imbalance from aerosol reductions (+0.2 W/m²/decade) and increasing greenhouse gases (+0.34 W/m²/dec) up to 2019!

This doesn't even include 2020 shipping desulphurisation yet!!

Breaking News!

March came in at 1.68°C above the 1850-1900 pre-industrial baseline, making it the 10th consecutive month at an all time recorded high, and the 9th consecutive month breaking the Paris limit of 1.5°C.

Jump of global temperature in past year is a combination of aerosol-induced warming over a few years and a half-baked El Nino. There is no need for new climate physics to understand the warming. El Nino + next La Nina mean may approach 1.5°C. See Hopium - mailchi.mp/caa/global-war…

Just published: gmd.copernicus.org/articles/17/23…

The 12 month running average surface air temperature now up to 1.57°C relative to the historical baseline (1900-1850).

Reminder: this does not mean the Paris target has been exceeded however, it does mean that we are getting closer.

I have a commentary in Nature about our disquieting inability to explain why 2023 was so warm. nature.com/articles/d4158…

The annual atmospheric increase in CO2 was a whopping 3.4 parts per million (ppm) in 2023.

Sure, it was fueled by El Nino, but I don't think anyone had on their bingo cards this large an increase.

Global mean temperature was record high for last 9 consecutive months. The current El Nino is not super but Jan-Feb temperatures were above 2016's due to the long-term global warming. Extreme warmth in the fall 2023 was probably not by El Nino. Data sources: NASA/GISS & NOAA/CPC.
