Global environmental challenges
Nicholas Stern, the British economist who warned five years ago that global warming could cost the world’s GDP as much as 20 percent a year by 2050, hasn’t given up on the United States taking action on climate even though he’s down on Washington for not passing a bill that would do just that.
“If you look around the world, of all places to sit and wonder where (climate policy is) going, this is probably the most pessimistic place — this city,” he told a small gathering of reporters at the World Bank’s headquarters in Washington, D.C. late this week.
But all one has to do is travel out of the U.S. capital to see enormous potential for taking action, he said. Stern is optimistic about U.S. companies in Silicon Valley and Boston and other places developing low-carbon technologies such as batteries for electric cars, or new biofuels that aren’t made out of food crops.
“There are so many technological ideas on the table that you don’t need all of them to work, just some,” he said.
No question about it: this has been a wild weather year so far in the United States, with record rains, droughts, wildfires and tornadoes. But a new study indicates that even routine weather events like rainstorms and cooler-than-normal days could pack a huge annual economic wallop.
Weather’s effect on all sectors of the U.S. economy may total $485 billion a year, as much as 3.4 percent of U.S. gross domestic product, according to research published in the current Bulletin of the American Meteorological Society. It is the first study to apply qualitative economic analysis to estimate the U.S. economy’s weather sensitivity.
Every workstation has a view. Much of the lighting comes from reflected sunshine. It’s so naturally quiet that unobtrusive speakers pipe in “white noise” to preserve a level of privacy. The windows open, and they’re shaded in such a way that there’s no glare. Even with the windows closed, fresh air circulates through vents in the floor. Extreme recycling prevails, not just of bottles, cans and kitchen refuse but beetle-blighted wood.
Welcome to the U.S. National Renewable Energy Laboratory, which contains some of the greenest office space on the planet.
OK, OK, enough fun with acronyms. HIPPO and ICE-T are flying climate laboratories, one in a Gulfstream V jet, the other in a refurbished C-130 military cargo plane.
A word has entered the language — at least, the language of environmental concern — that may be ready for prime-time. That word is Anthropocene. It’s the epoch we’re apparently living in, roughly translated as the Age of Man. The theory behind the name is that human beings have made such an impact on Earth’s geology that we should have an era named for us that differentiates this time from the tired old Holocene period.
Holocene means “entirely new,” but it’s been some 10,000 years since it started. Scientists and others meeting in London figure it may be time to move on.

The ongoing crisis at the Fukushima Daiichi nuclear plant in north-eastern Japan, seriously damaged by a March 11 earthquake and tsunami, has led to anti-nuclear protests in several countries and forced governments to rethink their energy policies.
The UK currently has 10 nuclear power stations, representing 18 percent of the country’s energy supply according to Energy UK. Should British Prime Minister David Cameron, like German Chancellor Angela Merkel, reverse his position on the safety of nuclear power?
How green is the Amazon?
Not as green as it used to be, as shown in an analysis of satellite images made during last year’s record-breaking drought.
Because greenness is an indication of health in the Amazon, a decline in this measurement means this vast area is getting less healthy — bad news for biodiversity and some native peoples in the region.
It took just 30 seconds to fell the tree. Hendri, 27, a skinny Indonesian from Central Kalimantan on Borneo island, skilfully wielded the chainsaw more than half his height. The result is a thunderous crash and a tree that is quickly cut into planks on the forest floor near by.

The devastating tsunami that struck the Indonesian islands of Mentawai may have caused about 450 deaths, with hundreds more still missing, and compounds the disaster caused in the country by the eruption of Mount Merapi in Java. Following a magnitude 7.7 earthquake, the Mentawai Islands were engulfed with estimated three-metre waves that affected thousands of households.
