Earth Hour! (today, 8:30 pm)

Yoga and more at this year's Earth Hour

On Mar. 27, 2010, people around the world are expected to join in a one-hour rally against climate change -- Earth Hour. For an hour starting at 8:30 pm, they will refrain from using electricity.

Participating organizations will shut their power to remind the world to conserve electricity. Before that, participants can join a free one-hour yoga session in the park... Earth Hour is organized by the Swiss-based non-profit environmental organization, World Wide Fund For Nature.

Change Thinking, Change Environment

We live on a finite planet. Sometimes our impact on it is greater than we realize. The choices we make every day — from our morning beverage to our business practices — are links in a chain of awesome connections we rarely imagine. But the bottom line is, our health is directly connected to the health of business and the health of the natural world. All three wither or grow and flourish together.

Himalayan nations to hold 1st climate talks

KATHMANDU (AFP) — South Asian ministers will gather in Nepal next week for talks on the threat that climate change poses to the Himalayas and to the 1.3 billion people dependent on water flowing from the mountains.

Experts say the Himalayan glaciers are melting at an alarming rate and with months to go before a key summit in Copenhagen, mountain nations are hoping to highlight the myriad of problems facing the region. Climate change campaigners refer to the Himalayas as the "third pole" and say the melting glaciers are the biggest potential contributors to rising sea levels after the north and south poles.

But until now Himalayan governments have not come together to lobby for ambitious emission reduction targets at December's Copenhagen summit, which aims to seal a new international climate change accord. "Nepal's message needs to be heard, and the message of the mountains needs to be heard," said World Bank water and climate expert Claudia Sadoff, who is helping Nepal's government organise the August 31-September 1 conference.

"The Himalayas have their own very real set of challenges, but there are also a lot of adaptation and mitigation opportunities in the mountains." Glaciers in the Himalayas, a 1,500-mile (2,400-kilometer) range that sweeps through Pakistan, India, China, Nepal, and Bhutan, provide headwaters for Asia's nine largest rivers, a lifeline for the 1.3 billion people who live downstream.

But temperatures in the region have increased by between 0.15 and 0.6 degrees Celsius (0.27 and 1.08 degrees Fahrenheit) per decade for the last 30 years, and the effects are already being felt.

In Nepal and Bhutan, the melting glaciers have formed vast lakes that threaten to burst, devastating communities downstream. Low-lying Bangladesh has always been prone to flooding, but leading environment scientist Atiq Rahman said the speed at which the Himalayan glaciers were melting meant floods were now "more frequent and more vigorous." Last year Nepal suffered its driest winter in 40 years, bringing the first widespread forest fires the country has experienced and destroying crops that depend on the winter rains.

Campaigners say that while the effects of climate change on low-lying South Asian countries such as Bangladesh and the Maldives are now well known, there is little international awareness of the vulnerability of the Himalayan region. "The general impression is that the Himalayas are huge, impregnable, pristine spaces no one can hurt. But the fact is that they are melting," said Tariq Aziz, leader of the WWF's Living Himalayas initiative.

"The Himalayas are not just mountains. They are a source of sustenance for millions and their most valuable commodity is water." Nepal's government, which has invited environment ministers from across South Asia to attend the talks, said it hoped to "take a regional voice on climate change to Copenhagen." "The glaciers are melting and the temperatures are rising in the Himalayas," said environment secretary Uday Raj Sharma. "This will ultimately affect people's livelihoods not only in Nepal but also downstream."

Some observers have expressed concern that India, which opposes binding carbon emission cuts, will drown out the voices of smaller countries such as Nepal, Bhutan and Bangladesh at the Copenhagen talks. More>>
