A study released by Dr. James Hansen, the dean of climate scientists and director of the Nasa Goddard Institute for Space Studies, concludes that the recent heat waves and extreme summers likely were caused by climate change.
Mangrove protection and restoration could be an economic way of mitigating greenhouse gases to curb global warming, research suggests.
Earlier study has found broad trends linking earlier spring weather, rising temperatures and increased forest fires, suggesting that climate change may play a role in fires like the Waldo Canyon blaze outside of Colorado Springs, which has burned more than 18,000 acres and consumed about 300 homes.

In most parts of the world, mountain glaciers are waning in response to global warming but the situation in Karakoram mountain range, home to the world’s second highest peak, K2, and straddling parts of China, Pakistan and India, defy the global trend and its glaciers getting thicker instead, say researchers.
The Greenland ice sheet is more sensitive to global warming than thought, for just a relatively small, but very long term, temperature rise would melt it completely, according to a study.
Globally, the United States is the second biggest polluter after China, and yet signs of progress in preventing the emission of greenhouse gases remain elusive.
Researchers from the universities of Florida and Nebraska used fossils to follow the evolution of horses from their earliest appearance 56 million years ago.
A patch of ancient seagrass in the Mediterranean sea is up to 200,000 years and could be the oldest known living thing on Earth, after scientists dated them.
