Unless the international community agrees to cut carbon emissions by half over the next generation, climate change is likely to cause large-scale human and economic setbacks and irreversible ecological catastrophes, a United Nations report says on Tuesday....
"We could be on the verge of seeing human development reverse for the first time in 30 years," Kevin Watkins, lead author of the report, told Reuters.
Dangerous climate change will be unavoidable if in the next 15 years emissions follow the same trend as the past 15 years, the report says.
To avoid catastrophic impact, the rise in global temperature must be limited to 3.6 degrees Fahrenheit (2 degrees Celsius). But carbon emissions from cars, power plants and deforestation in Brazil, Indonesia and elsewhere, are twice the level needed to meet that target, the U.N. authors say.
