WE ARE ALL WITNESSES - PEOPLE IN A CHANGING CLIMATE

The 24 panels of the "We are all witnesses - People in a Changing Climate" exhibition illustrate how climate change is already taking place in 16 countries in four countries.

CASE STUDY<br />

August 2010. A massive flood<br />

ravaged all of Leh, killing<br />

257 people in the district, injuring<br />

thousands, and destroying<br />

property, infrastructure and<br />

livelihoods. The flood was the<br />

result of very heavy rain falling<br />

over a small area. There were<br />

other factors: bright sunshine in<br />

June and July melted the snow<br />

faster than usual, leading to<br />

more humidity. The temperature<br />

remained low, leading to the<br />

formation of dense clouds at<br />

a low height. As these clouds<br />

moved over glaciers, they<br />

condensed further, resulting in<br />

a cloudburst. Cloud bursts and<br />

thunder showers, unprecedented<br />

in the history of Ladakh, caused<br />

flashfloods in almost all the<br />

valleys along the Indus river of<br />

the Leh district.<br />

REGIONAL CONTEXT AND BACKGROUND<br />

Ladakh is located at the northwestern side of the Himalayas, flanked by four mountains<br />

ranges namely Himalayan, Zanskar, Ladakh and Karakoram with extremely elevated snow<br />

capped peaks. These mountain chains and the Tibetan plateau are home for 45 000<br />

individual glaciers, covering an area of 90,000 sq km. They are the biggest storehouse for<br />

fresh water outside the polar caps, sometimes called “the water tower of Asia” or the<br />

“third pole”, and feed the major rivers of Asia. But the Himalayan glaciers, the source of<br />

water for billions, are retreating faster than glaciers in any other part of the world<br />

EVIDENCE OF <strong>CLIMATE</strong> CHANGE <strong>IN</strong> LADAKH<br />

Ladakh is a cold desert, with precipitation limited to as little as 2 days a year. In the<br />

past 20 to 25 years there has been a trend towards greater precipitation, but in a highly<br />

irregular pattern. For example, in 2002, there was almost no rainfall, but a large amount<br />

of snow. By contrast, the total precipitation recorded in 2006 was 150mm rain against<br />

an average over 1995 to 2007 of 32mm rain (Field Research Laboratory in Leh).<br />
