How Climate Change Is Transforming Our Planet

The Brazilian Amazon holds 40 percent of the world's remaining tropical forests. It plays a vital role in bio-diversity conservation and climate regulation. A recent study from the WWF reported that deforestation could wipe out or severely damage nearly 60 percent of the Amazon's rainforests by 2030.

UN Secretary-General Ban Ki-moon poses for photographers in front of a collapsed glacier at the atmospheric measuring station in Ny-Aalesund, a climate change research station on the Norwegian island of Svalbard.

East Africa faces a critical shortage of water and food. Climate change has aggravated the situation.

A view of the Huayna Potosi glacier in the Bolivian highlands. From the Himalayas to the Andes, faster-melting glaciers spell long-term risks for hydroelectric power generation and supplies of drinking water.

A child walks through a junkyard full of used plastic bottles on the outskirts of the northern Indian city of Chandigarh. Waste disposal and treatment can produce emissions of several greenhouse gases that contribute to global climate change.

A polar bear stands on a drifting piece of ice off the northern coast of Greenland. Ice in the region has melted much more quickly than experts had predicted.

Smoke whirls above a German lignite (brown coal) factory in North Rhine-Westphalia. Emissions from coal burning are a major cause of acid rain and air pollution and have been connected with global warming.

An iceberg melts near the Arctic Circle in Kulusuk, Greenland. Scientists say the effects of global warming in the Arctic region are increasing at an accerated rate. Glaciers are shrinking, and permafrost is thawing faster than ever, and there has been a notable increase in the temperature of the region's water.

Climate change has taken its toll on Africa's highest peak. Mount Kilimanjaro, the inactive volcano in northeastern Tanzania, has been losing its famed ice cap at a phenomenal rate. Researchers have calculated that the cap may completely disappear within 20 years.
