Severe drought spreading across Europe

June and July brought record high temperatures and big rainfall deficits in many parts of the European Union

Drought conditions were widespread across Europe during June and July.

FRISCO — The western U.S. isn’t the only part of the world experiencing severe drought this year. Across much of central Europe, extremely warm temperatures and lack of rainfall have combined to create the worst drought conditions since 2003.

Hardest hit have been France, Benelux, Germany, Hungary, the Czech Republic, northern Italy and northern Spain, according to new information released by the European Drought Observatory. The report includes data from satellite imagery showing that the areas with the largest rainfall deficits also recorded exceptionally high maximum daily temperatures, in some cases reaching record values.

Climate: Scientists warn of boreal forest ‘tipping point’

Climate zones in boreal forests are shifting northward ten times faster than the trees’ ability to migrate

More monitoring, adaptive management needed in crucial forest zones.

Staff Report

FRISCO — The world’s vast boreal forests, stretching around the globe at high latitudes, could reach a climate tipping during this century, according to a team of international researchers who said there needs to be more attention on climate mitigation and adaptation with respect to these forests.

Boreal forests make up about 30 percent of the planet’s total forest area and play a vital role in in the global climate system by capturing huge amounts of atmospheric carbon dioxide. Continue reading

Report: Little doubt that global warming will eradicate the world’s glaciers and ice sheets

‘The big picture across the world and over the long run is clear — carbon dioxide is making the ice melt’

FRISCO — Just like today, there were regional nuances in the Earth’s climate at the end of the last ice age — like solar radiation and ocean currents — that were factors in the meltdown of ice sheets and glaciers.

But the single biggest overriding cause was a global rise in temperatures caused by an increase in atmospheric carbon dioxide, a team of researchers said in a new study that measured isotopes in boulders that were uncovered during the global meltdown 11,000 years ago. Continue reading

U.S. wildfires surge to 10-year high

Staff Report

FRISCO — This year’s wildfire activity in the U.S. has surged to the highest level in 10 years, with the National Interagency Fire Center reporting that about 7.2 million acres have burned so far, and officials said they expect the wildfire season to intensify in the coming weeks.

The drought-stricken far West is hardest hit, with 16 large fires currently burning in Washington, 14 in California and 12 in Oregon. Forest Service Chief Tom Tidwell said federal agencies are currently spending about $150 million per day on fighting fires across the West. Continue reading

July 2015 was the hottest month on record for Earth

All signs point toward more record-breaking heat ahead

Only a few small parts of the planet saw anywhere near average or below average temperatures in July 2015.

There is little question that average global temperatures have been soaring since the 1970s.

Staff Report

FRISCO — July 2015 was the hottest month on record for planet Earth by any measure, federal climate scientists said this week during their monthly global climate update. What’s more, the researchers are 99 percent sure that 2015 will end up as the hottest year since humankind has been tracking the climate, going back to about 1880.

That would break the record set just last year and is sure sign that greenhouse gases are inexorably heating the planet, despite year-to-year variations in the rate of warming. Continue reading

Is western drought the new climate normal?

New study quantifies global warming effect on California drought

Staff Report

FRISCO — Researchers say there’s new evidence that global warming will push the western U.S. into the driest conditions in at least the past 1,000 years, as higher temperatures exacerbate drought condition in the region.

The new study by scientists with Columbia University’s Lamont-Doherty Earth Observatory and Cornell University focused on the current California drought, showing that warmer temps drive moisture from plants and soil into the air. Warmer temps likely worsened the California drought by 25 percent, the scientists concluded in their paper, published in the journal Geophysical Research Letters. Continue reading

Arctic sea ice dwindles to second-lowest extent ever

Antarctic sea ice extent below average for the first time in four years

Staff Report

FRISCO — In a mid-month update, researchers with the National Snow and Ice Data Center said that Arctic sea ice has dwindled to the second-lowest extent on record, with an above-average melt rate during the first half of August. The only time there was less sea ice was in 2012, which set the record for the lowest extent.

The NSIDC also reported that Antarctic sea ice extent is below the 1981 to 2010 average for the first time in nearly four years. Antarctic sea ice expanded by just 96,500 square miles between August 1 and August 17, and retreated around the Antarctic Peninsula, in the Ross Sea, and around the coast of Wilkes Land.
