The Earth is halfway to dangerous climate change, scientists say

ENDS (Environmental Data Services);May2009, Issue 412, p24
The article discusses a report published in "Nature" that said limiting atmospheric carbon dioxide levels to avoid drastic climate change is risky and recommends using a cumulative emissions budget of one trillion tonnes of carbon as a safer approach. This would reportedly cover emissions from the industrial revolution to 2500, with half already spent. According to the report, the maximum increase in global average temperature caused by greenhouse gases should be limited to 2 degrees Celsius to avoid dangerous climate change.
