Lyme disease isn't the only illness we need to worry about spreading to new parts of the globe as temperatures rise. Oliver Schmoll, is the manager responsible for climate at the World Health Organization's Regional Office for Europe. He explains which diseases are likely to become more common in Europe.

Black-legged ticks used to be virtually unknown in Canada, but that's no longer the case. As their population spreads north, so does the threat of Lyme disease. A notoriously difficult disease to diagnose, Lyme disease is carried by an insect that can be as small as a poppy seed.

The Aravali mountains are a lifeline for many communities in northern India, serving as a natural barrier against desertification and replenishing groundwater. But activists warn mining and construction are dramatically changing the region's landscape, and putting the mountains' future at risk.

Renowned Danish-Icelandic artist Olafur Eliasson has been named a UN Development Program Goodwill Ambassador for climate action. Manuela Kasper-Claridge spoke to him in New York about his new role and the changes he wants to see in the world.

Climate change is causing glaciers to melt at much faster rates than in the past.

That could mean trouble for Switzerland, which has more glaciers than any other European country and gets more than half of its power from hydroelectric dams.

Glaciers are already disappearing, and drastically in the Himalayas - home to the largest amount of snow and ice after the Artic and Antartic.

And with millions of people relying on mountain water resources, concerns are being expressed about the future water supply of people there.

Environmental activists are becoming increasingly vocal about our overheating world and are putting further pressure on governments and industry to take action. Many of them are also learning new tactics at so called climate camps. At one such camp in eastern France, over a thousand people attended.

Professor Alex Rogers of Oxford University says the latest climate observations should be a wake-up call. He is one of the world's pre-eminent marine biologists and has been analyzing the impacts of climate change on Antartic marine ecosystems.
