From: David Fogarty, Reuters Increased melting of glaciers and snow in the Himalayas and Tibetan Plateau threatens the food security of millions of people in Asia, a study shows, with Pakistan likely to be among the nations hardest hit. A team of scientists in Holland studied the impacts of climate change on five major Asian rivers on which about 1.4 billion people, roughly a fifth of humanity, depend for water to drink and to irrigate crops.

When scientists say the planet is warming, they usually point to rising air temperatures as proof. That's reasonable enough, especially since the warmth of the air temperature affects us directly so we feel the change the scientists are measuring. But it's also misleading: while the lower atmosphere has been gradually warming over the past 50 years, it happens unevenly, rising sharply for a year or two or even ten, then flattening out.

By Syful Islam DHAKA, Bangladesh (AlertNet) - Worsening sea water storm surges and overuse of irrigation have left fields, wells and ponds in parts of southern Bangladesh too salty to grow crops, leading to a growing exodus of farmers from the region.

• Climate change hurting African crop yields
• Farmers complain rains no longer predictable
• Africa needs development to adapt, experts say

By Tim Cocks and Loucoumane Coulibaly ABIDJAN, April 20 (Reuters) - From Africa's humid jungles and cocoa plantations to its growing semi-deserts and wilting maize fields, erratic weather linked to climate change may be ruining subsistence crops and export commodities alike.

By VERENA SCHMITT-ROSCHMANN (AP) BERLIN — The European Space Agency is launching a sophisticated satellite that scientists hope will help them pin down the effects of global warming on the Earth's ice packs more precisely by accurately measuring the thickness of ice. The CryoSat 2 mission, which starts Thursday after years of delays, will be able to pinpoint details of changes in polar ice so scientists can better understand the alarming picture of the world's retreating ice caps.
