Alaska, Southwest could see early season forest fires
April precipitation may have helped dampen the potential for a severe wildfire season in parts of the Rocky Mountain region and in the adjacent Great Plains, according to a new outlook from the interagency Rocky Mountain Area Coordination Center.
The projections is based on various seasonal indicators including precipitation, snowpack average, temperatures, wind, plant and soil moisture, and the timing of green-up. These indices support a below average to near average fire season in 2016.
Flooding, droughts and wildfires all expected to increase
New European climate modeling doesn’t paint a pretty picture for the decades ahead. With global warming, Europe is facing a progressively stronger increase in multiple climate hazards, according to the European Commission’s Joint Research Centre.
Global warming has killed half a billion trees across the U.S.
Scientists tracking massive forest die-offs say a new study may help forest managers learn how to predict which trees will succumb to global warming — and what the implications are for the global carbon balance.
“There are some common threads that we might be able to use to predict which species are going to be more vulnerable in the future,” said University of Utah biologist William Anderegg, explaining that recent tree-killing droughts in the western U.S. were marked more by elevated temperature than by a lack of rainfall.
“These widespread tree die-offs are a really early and visible sign of climate change already affecting our landscapes,” Anderegg said.
NASA, Harvard scientists study wine harvest dates in cool-weather countries
Global warming is changing centuries-old climate patterns that are crucial for wine production in cool-weather regions, a new study from NASA and Harvard concludes. After analyzing climate records and grape harvesting dates from 1600 to 2007, the scientists found that harvests started happening much earlier during the second half of the 20th century.
These shifts were caused by changes in the connection between climate and harvest timing. Between 1600 and 1980, earlier harvests were linked to years with warmer and drier conditions during spring and summer. After that, global warming caused earliers harvests in years without droughts.

El Niño didn’t exactly go gangbusters in southwest Colorado last month, where the key river basins received only about 35 percent of average February precipitation. Statewide mountain precipitation was only slightly better, at 56 percent of normal.
“February in the mountains of Colorado is typically a slightly drier month than compared to say, April. But a dry February like this could have big ramifications should April and May not pan out” said Brian Domonkos, Snow Survey Supervisor with the Natural Resources Conservation Service.

Current regional dry spell appears to be the most severe in more than 900 years
The Mediterranean region may already be feeling the impacts of human-caused climate change, according to a new tree ring study that compared an ongoing drought in the region with historic climate conditions.
Although there are still a few months left in the rainy season, this year’s El Niño hasn’t exactly been the drought buster California was hoping for. Thus far, plentiful precipitation in the northern part of state will go a long way toward replenishing reservoirs, but central and southern California have remained relatively dry.
The “exceptional drought” footprint is now spread across about 38 percent of the state, as compared to 45 percent three months ago, and precipitation in the key snowpack areas of the Sierra Nevada has been about average. Farther south, especially in the L.A. Basin, precipitation is still well below average for the rainy season to date.
