Jet stream study set to improve future climate predictions

They then used a range of innovative methods to demonstrate that 50% of these shifts are directly attributable to global warming, with the remainder triggered by other climate-related changes, including warming of the tropical Pacific and the upper tropical atmosphere, and the strengthening of winds in the stratosphere. “We

The 2024 Election Outcome Could Boost the Case for Geoengineering

Legal Planet

Proposals for geoengineering — reducing warming after carbon emissions are already in the atmosphere — range from being almost literally garden variety to the realm of science fiction. loss of stratospheric ozone); important aspects of regional climate (e.g.,

What We’re Watching: Wildfire Smoke and Trump Administration Mirrors

Union of Concerned Scientists

When combined with summer heat and ground level ozone, conditions can worsen further. It’s a good time for a letter to the editor about what you’re experiencing during Danger Season, because it’s NOT a good time to roll back funding or staffing for FEMA and the National Oceanic and Atmospheric Administration (NOAA ).

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

2022 updates to model-observation comparisons

Real Climate

Satellite comparisons The weighted atmospheric temperatures that are retrieved from the MSU/SSU, and now AMSU , instruments are not standard CMIP diagnostics (though they should be!). The CMIP3 ensemble continues to astound! CMIP3 model ensemble compared to surface temperature observations (in ºF), showing two decades of skillful projection.

Oceans may start emitting ozone-depleting CFCs

Successful Green

As atmospheric concentrations of CFC-11 drop, the global ocean should become a source of the chemical by the middle of next century, a new MIT study predicts. The world’s oceans are a vast repository... The post Oceans may start emitting ozone-depleting CFCs appeared first on successful GREEN.

The definitive CO2/CH4 comparison post

Real Climate

But methane’s role in atmospheric chemistry and as a source of stratospheric water vapour means that it has a bigger effect on climate than just the direct effect of its concentration. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different.
