The Great Lakes may be drying up


Grist

On Earth, cycles are the norm. Tides, carbon, water, life — they ebb and flow. Change, by itself, isn’t necessarily strange. What is strange is when cycles are broken.

In other words, it’s not strange on its own that the level of the Great Lakes is dropping. It is strange that, when the lakes’ levels normally change over a 13 year cycle, they’ve now been going down for 16 years straight. That’s 10 more than they should have been dropping for.

LiveScience:

Water levels have been declining since 1998, [climate scientist Carl] Watras told Live Science. “Our lakes have never been lower than they are.”…

Climate change means more wildfires, and that means lots more air pollution


Grist

Wildfires not only jeopardize lives and property. They also cause air pollution — from planet-warming carbon dioxide to health-endangering soot and nitrogen oxides. This pollution can trigger hospital visits. It can also hamper agricultural output, and damage forests and other ecosystems.

This will be a particular problem in California, according to new research published in the journal Environmental Science & Technology.

Scientists analyzed future climate and population scenarios for the state and forecast that air pollution from wildfires in California could increase by between 19 and 101 percent by the end of the century. They found that the worst effects will likely be experienced in Northern California, particularly in the Sierra Nevada Mountains and in the Klamath-Siskiyou region at Oregon’s border.

Get ready for more “extreme” El Niños


Grist

Batten down the worldwide hatches. Scientists say baby Jesus’ meteorological namesake will become a thundering hulk more often as the climate changes.

The latest scientific projections for how global warming will influence El Niño events suggest that wild weather is ahead. El Niño starts with the arrival of warm water in the eastern Pacific Ocean, and it can culminate with destructive weather around the world. It was named by Peruvian fishermen after the infant Jesus because the warm waters reached them around Christmas.

We’ve previously told you that El Niños appear to be occurring more frequently as the climate has been changing. The authors of the latest paper on this subject, published Sunday in the journal Nature Climate Change, don’t project that El Niños will become more common in future. What they do project, though, is that twice as many El Niños will be of the “extreme” variety.
