Climate change in the news

By Zaina Adamu, CNN

Whispers about global warming got louder in 2012 after a string of unforgiving natural disasters and rising global temperatures. Here’s a look at some recent stories regarding climate change.

2012 drought: just the beginning?

More anxiety surrounding climate change arose with the release of the “Iowa Climate Statement (PDF),” announced in Des Moines this week. It predicts that Iowa’s harsh drought season was a precursor of what is to come for the top grain-producing state.

The statement, signed by 138 scientists and 27 Iowa colleges and universities, suggests that if there is little rain this winter and spring, “it would become a multiyear drought that would be serious,” according to Jerry Schoor, professor of civil and environmental engineering at the University of Iowa.

But fret not, the scientists added: The drought should – and possibly will – prompt innovation in renewable energy, which would limit the number of greenhouse gases, regulating temperatures.

CIA closes its environment wing

The Central Intelligence Agency will permanently close the doors of its Center on Climate Change and National Security unit, formed in 2009 to examine the relationship between global warming and security measures.

The short-lived branch drew criticism in its grass-roots stage, particularly from Wyoming Republican Sen. John Barrasso, who said in a statement that he “offered an amendment on the Senate floor to eliminate the center because it was unnecessary, wasteful and totally out of place.”

CIA spokesman Todd Ebitz told the New York Times that the agency will continue to observe intelligence challenges that may arise, but not in an individualized office.

Fracking a ‘no-go’ for NY in 2012

Remember “fracking”? It was an often-used term during the 2008 presidential race. The controversial drilling process, also known as hydrofracking, entails injecting large quantities of chemicals and other fluids into the Earth’s surface in order to crack rocks surrounding oil wells, allowing for more gas resources.

On Tuesday, New York Gov. Andrew Cuomo confirmed that the state will miss its deadline on fracking regulations because of environment and health concerns surrounding the drilling.

“It has potential economic benefits if the state goes forward with fracking,” Cuomo said. “But we want to make sure that it’s safe.”

Rising CO2 levels

A report released by the World Meteorological Organization revealed that carbon dioxide emissions increased to 390.9 parts per million (ppm), up 30% since 1990.

“What it shows isn’t surprising, but it obviously has very important implications for the future well-being of the planet,” said Richard Allan of the Department of Meteorology at the UK's University of Reading.

Carbon dioxide is the No. 1 greenhouse gas emitted into the Earth’s atmosphere.

Kyoto Protocol resumes week-long conference

The Kyoto Protocol, an international agreement among 37 industrialized countries to reduce greenhouse gas emissions, will convene for its annual weeklong conference Monday to discuss new ways of combating climate change.

The protocol was signed in 1997 and is scheduled to end in 2012.

Extending the protocol will be discussed, but if a compromise is not reached, there may not be another international environment-related pact until 2020.

Lemmings extinct because of Ice Age warmth

New research shows that rapid climate change led to the extinction of lemmings, small rodents that inhabited the Arctic during the last Ice Age.

Their presence came in waves during the Late Pleistocene, 11,700 to 126,000 years ago. Experts believe they died out and then reappeared on several occasions in the span of 114,300 years.

The findings go against some suspicions suggesting that humans play a key factor in global warming.
