Late blight, which caused the Irish Potato Famine of the 1840s and 1850s, is killing potato and tomato plants in home gardens from Maine to Ohio and threatening commercial and organic farms, U.S. plant scientists said on Friday. "Late blight has never occurred this early and this widespread in the United States," said Meg McGrath, a plant pathologist at Cornell University's extension center in Riverhead, New York.
She said the fungal disease, spread by spores carried in the air, has made its way into the garden centers of large retail chains in the Northeastern United States. "Wal-mart, Home Depot, Sears, Kmart and Lowe's..."

Chaos

A recent drought completely shut down the Amazon Basin's carbon sink, by killing trees and slowing their growth, a ground-breaking study led by researchers at the Universities of Exeter and Leeds has found.
Previous research has suggested that the Amazon - the most extensive tropical forest on Earth and one of the "green lungs" of the planet - may be gradually losing its capacity to take carbon from the atmosphere. This new study, the most extensive land-based study of the effect of drought on Amazonian rainforests to date, paints a more complex picture, with forests responding dynamically to an increasingly variable climate....
Co-author Professor Oliver Phillips, from the University of Leeds, said: "For more than 20 years the Amazon has been providing a tremendous service, taking up hundreds of millions more tonnes of carbon every year in tree growth than it loses through tree death. But both the 2005 and 2010 droughts eliminated those net gains."

Vancouver Island is home to the wettest place in North America--and right now it's on fire.
Drought has plunged the the Port Alberni-Clayoquot Region, part of Canada's only rainforest, into one of the worst dry seasons on record. Forest fires are spreading quickly through sun-scorched woods that, in the past, have received almost seven metres--or 22 feet--of precipitation per year.
The fire, which has been burning since last Saturday on Dog Mountain near Sproat Lake, has reached over 245 hectares and is still spreading....

Las Vegas is parched. A 14-year drought has left Lake Mead, the local water source, dangerously low. It has dropped 100 feet in the past decade. If it drops 12 more feet, federal water rationing rules will kick in. Some climate scientists predict that will happen in the next year. And most believe the situation will only worsen over time.
The view from inside Las Vegas' Mandalay Bay Resort and Casino, however, is considerably rosier. That's where scientists, activists, and bloggers have assembled this week for the Heartland Institute's 9th International Conference on Climate Change, which I've been following via live stream. It's the world's largest gathering of "climate skeptics"--people who believe, for one reason or another, that the climate change crisis is overblown....

An effort on the scale of the Apollo mission that sent men to the Moon is needed if humanity is to have a fighting chance of surviving the ravages of climate change. The stakes are high, as, without sustainable growth, "billions of people will be condemned to poverty and much of civilisation will collapse". This is the stark warning from the biggest single report to look at the future of the planet -- obtained by The Independent on Sunday ahead of its official publication next month. Backed by a diverse range of leading organisations such as Unesco, the World Bank, the US army and the Rockefeller Foundation, the 2009 State of the Future report runs to 6,700 pages and draws on contributions from 2,700 experts around the globe. Its findings are described by Ban Ki-moon, Secretary-General of the UN, as providing "invaluable insights into the future for the United Nations, its member states, and civil society".

Depletion

New Envisat images highlight the dramatic retreat of the Aral Sea's shoreline from 2006 to 2009. The Aral Sea was once the world's fourth-largest inland body of water, but it has been steadily shrinking over the past 50 years since the rivers that fed it were diverted for irrigation projects. As the Aral Sea evaporated, it left behind a 40 000 sq km zone of dry, white salt terrain now called the Aral Karakum Desert. Each year violent sandstorms pick up at least 150 000 tonnes of salt and sand from the Aral Karakum and transport it across hundreds of km, causing severe health problems for the local population and making regional winters colder and summers hotter. In an attempt to mitigate these effects, vegetation that thrives in dry, saline conditions is being planted in the former seabed.
