Scientists have a new name for a weather pattern reshaping how the West gets its water: so-called “snow-eater” heat waves.

Twelve fires are over 100,000 acres.

As communities across the West keep a close eye on water supplies and wildfire risk, a new federal drought forecast highlights where relief may be on the way, and where dry conditions are likely to continue.

Coal-fired power generation jumped 13% in the U.S. last year, according to a recent report from the federal Energy Information Administration. That helped push carbon emissions from the power sector up about 4% — the first rise after years of declining emissions.
