Extreme Weather Hits Record High in 07

According to Reuters, the world experienced a series of record-breaking extreme weather events early in 2007. Here is an exerpt of the article.
GENEVA (Reuters) - The world experienced a series of record-breaking weather events in early 2007, from flooding in Asia to heatwaves in Europe and snowfall in South Africa, the United Nations weather agency said on Tuesday.
The World Meteorological Organization (WMO) said global land surface temperatures in January and April were likely the warmest since records began in 1880, at more than 1 degree Celsius higher than average for those months.
There have also been severe monsoon floods across South Asia, abnormally heavy rains in northern Europe, China, Sudan, Mozambique and Uruguay, extreme heatwaves in southeastern Europe and Russia, and unusual snowfall in South Africa and South America this year, the WMO said.
"The start of the year 2007 was a very active period in terms of extreme weather events," Omar Baddour of the agency's World Climate Program told journalists in Geneva.
While most scientists believe extreme weather events will be more frequent as heat-trapping carbon dioxide emissions cause global temperatures to rise, Baddour said it was impossible to say with certainty what the second half of 2007 will bring.
"It is very difficult to make projections for the rest of the year," he said.
The Intergovernmental Panel on Climate Change (IPCC), a U.N. umbrella group of hundreds of experts, has noted an increasing trend in extreme weather events over the past 50 years and said irregular patterns are likely to intensify.
South Asia's worst monsoon flooding in recent memory has affected 30 million people in India, Bangladesh and Nepal, destroying croplands, livestock and property and raising fears of a health crisis in the densely-populated region.
Heavy rains also doused southern China in June, with nearly 14 million people affected by floods and landslides that killed 120 people, the WMO said.
England and Wales this year had their wettest May and June since records began in 1766, resulting in extensive flooding and more than $6 billion in damage, as well as at least nine deaths. Germany swung from its driest April since country-wide observations started in 1901 to its wettest May on record.
Mozambique suffered its worst floods in six years in February, followed by a tropical cyclone the same month, and flooding of the Nile River in June caused damage in Sudan.
Uruguay had its worst flooding since 1959 in May.
Huge swell waves swamped some 68 islands in the Maldives in May, resulting in severe damage, and the Arabian Sea had its first documented cyclone in June, touching Oman and Iran.
Temperature records were broken in southeastern Europe in June and July, and in western and central Russia in May. In many European countries, April was the warmest ever recorded.

Climate Change Doubles Hurricanes

A new study links hurricane frequency and climate change, according to the Environmental News Service.
Twice as many Atlantic hurricanes formed each year from 1995 to 2005, on average, than formed during parallel years a century ago finds a new statistical analysis of hurricanes and tropical storms in the north Atlantic. The researchers conclude that warmer sea surface temperatures and altered wind patterns associated with global climate change are responsible for the increase.

(Photo courtesy NOAA) The study, by Greg Holland of the National Center for Atmospheric Research, NCAR, and Peter Webster of Georgia Institute of Technology, is published online today by the Royal Society of London.
"These numbers are a strong indication that climate change is a major factor in the increasing number of Atlantic hurricanes," says Holland.
For the 2007 Atlantic hurricane season, NOAA scientists predict 13 to 17 named storms, with seven to 10 becoming hurricanes, of which three to five could become major hurricanes of Category 3 strength or higher. An average Atlantic hurricane season brings 11 named storms, with six becoming hurricanes, including two major hurricanes.
The analysis by Holland and Webster identifies three periods since 1900, separated by sharp transitions, during which the average number of hurricanes and tropical storms increased and then remained elevated and relatively steady.
The first period, between 1900 and 1930, saw an average of six Atlantic tropical cyclones each year, of which four were hurricanes and two were tropical storms.
From 1930 to 1940, the annual average increased to 10, consisting of five hurricanes and five tropical storms.
In the final study period, from 1995 to 2005, the average reached 15, of which eight were hurricanes and seven were tropical storms.
This last period has not yet stabilized, which means that the average hurricane season may be even more active in the future.
Holland and Webster say it is not possible at this time to predict the level at which the frequency and intensity of storms will stabilize.

Weather Channel Tackles Climate Change

A story in the New York Times reports on The Weather Channel's take on Climate Change. Here is an excerpt:
“If The Weather Channel isn’t talking about climate change and global warming, who is?” said Kaye Zusmann, the vice president for program strategy and development for the network. “It’s our mandate.”
The network, which had been gearing up for the opening of hurricane season on Friday, sees the engagement with the issues surrounding climate change as important for content and for business.
“We have a point of view, and we think it’s really important to articulate why it’s happening. Secondarily, it’s good business,” said Ms. Wilson, the network president. “Many consumers want to know, ‘What should I do?’ ”
The lightning rod for controversy, so to speak, is Heidi Cullen, the network’s resident climate expert.
In December, she raised the ire of Fox News and others by writing on her
weather.com blog that the American Meteorological Society should not give its “seal of approval” to any meteorologist who “can’t speak to the fundamental science of climate change.” (There are now more than 1,700 comments on that one post.)
Dr. Cullen, a tiny woman who speaks with conviction, said she believed that people were “finally seeing climate connected to weather,” but that a lot of information still needs to be disseminated. “If you turn on the local forecast, you wouldn’t necessarily know that global warming exists,” she said.
Far from being intimidated by the political backlash, Dr. Cullen and executives at the channel say they have embraced the issue of global warming. Dr. Cullen is host of the weekly show “Forecast Earth,” formerly named “The Climate Code” where she has entertained such guests as former Vice President
Al Gore. She also appears on the channel’s other programming with segments on hybrid taxicabs in New York City and the development of more fuel-efficient aircraft.
The network’s other programs have also directly engaged the elephant in the room — or, in this case, the polar bear on the melting ice cap: a recent anniversary roundup of “The 100 Biggest Weather Moments” listed global warming as No. 1. And the network is training its meteorologists so that they can discuss long-term trends as well as five-day forecasts.
“Weather information on an on-demand basis is the foundation of what we do, and a deeper experience on an emotional level brings us to life.” Ms. Wilson said.
Besides sections devoted to travel, golf and pets (yes, pets), the weather.com Web site also has interactive features like blogs and user-submitted videos — as well as consumer-information sections that give users tips on how to prepare for a severe storm, or how to reduce a carbon footprint.

Is Climate Change Killing Bees?

Salon has a long, informative article about Colony Collapse Disorder. While it raises more questions than it answers, the questions it raises are important.
The media has done a very good job of telling all sides. But the problem is, how do you motivate people to change the way they are? Where I live, I try to live pretty low on the food chain and avoid the temptation of most of the things that people have. People are just incredible consumers and runners of fuel and buyers of gadgets. How do you change that? It's as if there's an ethical or a moral blank spot there. I don't like to preach, but it's pretty obvious: When you're killing the corn belt by growing fuel to run SUVs, there's a very bad disconnect somewhere along the line.

Clouds and Climate Change

"Scientists are peering into the clouds near the top of the world, trying to solve a mystery and learn something new about global warming. The mystery is the droplets of water in the cluds. With the North Pole just 685 miles away, they should be frozen, yet more of them are liquid than anyone expected. So the scientists working out of a converted blue cargo container are trying to determine whether the clouds are one of the causes — or effects — of Earth’s warming atmosphere. " Read the rest of this story here.
