Detroit Flooding Previews Risks from a Warming Climate

Circle of Blue

It’s hard to pin individual storms on climate change, but the science is clear that atmospheric warming leads to more events like last weekend’s rainfall. This may be a trivial sum for small temperature changes, but with climate projections forecasting a few degrees of atmospheric warming, it starts to add up. “You

AR6 of the best

Real Climate

Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climate change was scant. As one example, the rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. 692-697, 2012.

FIRO to Avoid Water FOMO: How to Save Every Drop with Smart Reservoir Operations in California

Union of Concerned Scientists

FIRO started in California and has since gone worldwide Once upon a time, there was (and still is) a megadrought in California that peaked in the acute drought of 2012 to 2016. In other words, FIRO avoids the fear of missing out (FOMO) on water that you could have stored if you had better forecasting.

Evaluation of GCM simulations with a regional focus.

Real Climate

I use GCMs to provide information about large-scale conditions, processes and phenomena in the atmosphere that I can use as predictors in downscaling future climate projections. The benchmark for the evaluation was the recent ERA5 reanalysis , which probably is the best data for describing the historical state of Earth’s atmosphere.

The issue here is a disturbed carbon cycle that now is out of balance because carbon has been taken from Earth’s crust and injected into the atmosphere. 2012) to understand why such small samples give non-robust and insufficient information for making regional future projections. 775-779, 2012.

Sea Level Rise is Already Threatening Communities

Union of Concerned Scientists

The primary cause of accelerating sea level rise is human activity As people burn fossil fuels and emit heat-trapping gases like carbon dioxide, our atmosphere and our oceans warm up. As the ocean warms, it expands. Historically, this was the dominant cause of sea level rise. Source: Metropolitan Transportation Authority.
