Do they know what an ecosystem is?
Threats to habitats and animals. What impact is climate change having already?
The short answer is a simple one: A 25-minute interview with one of the world's leading climate scientists, from The Alcove, on YouTube. There are also excellent resources all over the internet for this.
Using your computer's "down time", you'll be able to help some of the world's leading scientists produce even better models of our climate. You are here: Just like us, when cows eat, methane gas builds up in their digestive system and is released in the form of… a fart! Taken all together, the equations describe roughly how the climate works.
Apes like orangutans , which live in the rainforests of Indonesia , are under threat as their habitat is cut down, and more droughts cause more bushfires. HarperCollins, 2005.
But climate change doesn't necessarily mean things will get hotter. Politics This Changes Everything: It happens at home, in the grocery store, online, at work, and out in the wider world.
Boiling Point: Global warming will increase the risk of drought in some regions. On some predictions, climate change flooding could make around 100—200 million people permanently homeless by 2100. Mosquitoes are expected to extend their range north, putting more people at risk from malaria. Over 47,000 computers in the world are tackling the project, which works just like SETI home.
