Climate: February 2014 cooler than average in U.S.

Dry conditions persist in far West

asf

February 2014 emperatures varied widely across the country.

Staff Report

FRISCO — The average February temperature across contiguous United States was well below the 20th century average. With an average reading of 32.2 degrees Fahrenheit (1.6 degrees below average), last month will go down in the books at the 37th-coldest February on record, the National Climatic Data Center reported in its regular monthly update.

The winter season overall (December to February) was 1.0 degrees Fahrenheit below average, making it the coldest winter since 2009-2010. This winter stood in sharp contrast to the last two winters, and most winters of the past two decades, when temperatures were predominately warmer than the 20th century average, the climate data center said.

Climate: How will Europe cope with growing flood risks?

New study outlines adaptation options

FRISCO —Europe needs to update its risk management strategy to adapt to the growing threat of floods, an international team of experts said this week, projecting that flood costs will climb dramatically during the next few decades.

By 2050, average annual flood-related costs could soar to €23.5 billion, up from the €4.9 billion in average annual losses for the 2000 to 2012 period, according to a new study published in the journal Nature Climate Change by researchers from the International Institute for Applied Systems Analysis and other European institutions.

Eying the widespread transnational threat, the team of economists and hydrologists advocated for restructuring pan-European funding mechanisms to better manage flood risks. Continue reading

Climate: Is there a link between this winter’s extreme weather and global warming?

FRISCO — Climate scientists and weather experts are edging ever-closer to linking between more frequent extreme weather events and global warming. In a mid-month bulletin, the World Meteorological Organization focused on persistent flooding in the UK and extreme cold weather in the Eastern U.S.The organization also pointed out that some southern hemisphere land areas were near record warm during the first several weeks of 2014.

Climate: World’s hottest areas getting even warmer

‘The hottest extremes got hotter and the events happened more often’

FRISCO — While the rate of increase in average global surface temperature varies, there’s a more steady upward trend in extreme heat events over land, according to scientists with the ARC Centre of Excellence for Climate System Science.

The international research team published their findings after studying the rise of temperatures at the extreme end of the spectrum where impacts are felt the most.

“It quickly became clear, the so-called “hiatus” in global average temperatures did not stop the rise in the number, intensity and area of extremely hot days” said one of the paper’s authors Dr Lisa Alexander. Continue reading

Will global warming drive more extreme Arctic storms?

FRISCO — A changing air pressure regime over the Arctic resulting from warmer temperatures may be driving an increase in extreme storms in the region. The hurricane-like cyclones that traverse the northern waters from Iceland to Alaska may foreshadow even more intense weather ahead, according to Dr. Stephen Vavrus, of the University of Wisconsin-Madison.

“This research shows that the Arctic appears to be expressing symptoms expected from ongoing climate change,” Vavrus said, explaining the findings of the study published in Geophysical Research Letters.

“The long-term decline in atmospheric pressure over most of the Arctic is consistent with the response typically simulated by climate models to greenhouse warming, and this study finds a general corresponding increase in the frequency of extreme Arctic cyclones since the middle 19th century,” he said.

Colorado: Sen. Bennet calls for climate change action

Senator from Colorado says massive switch in energy policy needed to address climate impacts to Colorado

By Summit Voice

FRISCO —U.S.  Sen. Michael Bennet, a Colorado Democrat, is calling on state residents to support a far-reaching renewable energy plan as a way to tackle global warming.

According to Bennet, Colorado’s economy is already feeling the effects of extreme weather, including shorter ski seasons, the constant threat of wildfire, and multi-year droughts that threaten Colorado’s $40 billion agriculture economy.

Bennet says the nation must take action to address a changing climate.

“One big step we can take is to create an energy plan that is relevant to our needs and interests in the in the 21st century and not stuck deep in the 1900s. It means investing in new energy technologies — and the jobs that come with it — that will actually allow us the luxury of not importing oil from the Persian Gulf anymore,” Bennet said in an email aimed at getting people to sign a petition in support of a forward-looking energy plan.

Climate: Storm surge damage costs forecast to soar

‘If we ignore this problem, the consequences will be dramatic’

FRISCO — Watching damage from individual megastorms like Hurricane Sandy and Typhoon Haiyan is bad enough, but the outlook for coming decades is downright scary.

According to new research, global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century without significant adaptation measures.

“If we ignore this problem, the consequences will be dramatic,” said Jochen Hinkel, a researcher with the Berlin-based think-tank Global Climate Forum. Continue reading
