High temperatures and a lack of rain spread serious drought conditions across Europe this summer.
Study tracks increase in extreme conditions
FRISCO — Scientists taking a close look at the last 50 years — the modern global warming era — found that droughts and heat waves are happening simultaneously much more frequently than in the past.
The climate experts at the University of California, Irvine analyzed data gathered from ground sensors and gauges since 1960 and crunched the numbers with a statistical model to track the upswing.
“Heat waves can kill people and crops while worsening air quality, and droughts exacerbate those serious impacts,” said senior author Amir AghaKouchak, assistant professor of civil & environmental engineering. “With these two extremes happening at the same time, the threat is far more significant.” Continue reading

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.
By Bob Berwyn
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.

Study tracks eastern Mediterranean climate trends

FRISCO — Rapidly warming sea surface temperatures are resulting in more extreme coastal rainstorms, Russian and German researchers said after analyzing climate data from the eastern Mediterranean and the Black Sea.
The impetus for the study was a deadly 2012 flash flood in the Russian city of Krymsk, near the Black Sea coast that killed 172 people. The Black Sea and eastern Mediterranean have warmed by about 2 degrees Celsius since the early 1980s.
The study was led led by scientists at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, and published in the international journal Nature Geoscience. Continue reading

A new study documents a distinct increase in extreme rainfall events linked with global warming.
Southeast Asia sees biggest increase in dangerous rainstorms
FRISCO —There’s clear evidence that global warming is causing more frequent record-breaking rainstorms, according to scientists with the Potsdam Institute for Climate Impact Research.
The upward trend in extreme rainfall events has been striking in the last 30 years, and particularly noticeable in Southeast Asia, the researchers said in a new study, explaining that the spike lies outside the range of natural variability.
The worldwide increase is consistent with rising global temperatures, which are caused by greenhouse-gas emissions from burning fossil fuels, the scientists said. Continue reading

Above average temperatures are expected to persist across the Far West for the next three months.
Global warming is here …
FRISCO — With El Niño still strengthening in the Pacific Ocean, many parts of the northern hemisphere are breaking all-time heat record this week, including England, where tennis players in the early Wimbledon rounds have to contend with the hottest temperatures ever recorded in the UK.
The ongoing heatwaves parts of Asia, North America and Europe may be a clear sign that 2015 will, as expected, end up as the hottest year on record for the globe, and a sign of trouble ahead, as deadly heatwaves are expected to increase and put millions of people at risk, with the threat growing every year, according to a recent climate study.

Global temperatures have reached record levels the past few months, with 2015 on track to be warmest year ever.
Heat waves, increased air pollution seen as key climate risks for Colorado
FRISCO — A new EPA report suggests that failing to curb greenhouse gas emissions could cause up to 57,000 additional deaths across the U.S. in coming decades due to poor air quality.
The study was released as part of the run-up to the finalization of the controversial Clean Power Plan, which aims to cut greenhouse gas emissions from power plants. The EPA is set to finalize the plan later this summer.
The report’s findings were part of the discussion at a Denver roundtable convened by Environment Colorado this week, as EPA experts joined with state leaders and health experts to bring the message home to Colorado.
“Climate change is already having an impact on human health and is challenging EPA’s ability to fulfill its mission,” said EPA regional climate change coordination Laura Ferris. “We know that taking action to reduce global greenhouse gas emissions will significantly benefit Americans by reducing health impacts, saving lives and avoiding more costly damages across the economy.” Continue reading
