‘The ETS2, aims to reduce carbon dioxide (CO2) emissions from fuel combustion in buildings, road transport and other sectors like small industry not covered by the existing EU Emissions Trading System (ETS1).’

Social fairness key to success of the EU’s new ETS2 cap and trade system

The introduction of the EU’s second ‘cap and trade’ emissions trading system (ETS2) for the road transport and buildings sectors will help spur Europe’s decarbonisation ambitions, accelerating the shift to cleaner fuels and technologies. Providing early financial support to vulnerable households and businesses, policy coherency, strong public backing, transparency and clear communication will be key to its success, according to two European Environment Agency (EEA) briefings published today.

Tonga eruption increases chance of temporary surface temperature anomaly above 1.5 °C - Nature Climate Change

The Hunga Tonga–Hunga Ha’apai eruption in January 2022 injected large amounts of water vapour into the atmosphere. Here, the authors show that this can cause additional warming over the next years, which increases the likelihood of exceeding 1.5 °C warming over a short time period.

The unexpected radiative impact of the Hunga Tonga eruption of 15th January 2022 - Communications Earth & Environment

Perturbations to the global climate system changed from net cooling to net heating during the first month after the 2022 Hunga Tonga-Hunga Ha-apai eruption, according to radiative forcing estimates based on satellite, ground-based, in situ and radiosonde observations.

Global perturbation of stratospheric water and aerosol burden by Hunga eruption - Communications Earth & Environment

The eruption of the submarine Hunga volcano in January 2022 led to a 13% increase in global stratospheric water mass and a 5-fold increase in stratospheric aerosol load, according to satellite data complemented by ground-based observations and atmospheric transport modelling.

#Methane on my mind

20y ago, methane concentrations stabilized, giving hope we’d at least addressed one greenhouse gas, but then its concentrations took off again, esp the last 3yrs.

The U.S. Geostationary Operational Environmental Satellite (#GOES) can detect methane leaks, and their geostationary orbit allows them to monitor these leaks, yielding better estimates for volume (provided cloud free skies).

🌍🌡️ According to the joint State of the Climate in Europe report from the World Meteorological Organization and #CopernicusClimate, in Europe, temperatures have warmed significantly during the industrial era. The 2022 annual average temperature for Europe was between the second and fourth highest on record. Europe as a whole also saw its warmest summer on record.

As an end of the month reminder, look at how much faster the land is warming (where we live) - this point can be obscured in the global mean plots...
