GREENHOUSE GAS EMISSIONS
EPA - Environmental Protection Agency (U.S.)

Greenhouse Gas Emissions
2012 Inventory of Greenhouse Gas Emissions and Sinks
Prepared annually by EPA, the national greenhouse gas inventory report presents estimates of U.S. greenhouse gas emissions and sinks for the years 1990 through 2010. This report also discusses the methods and data used to calculate the emission estimates.
Greenhouse Gas Overview
Gases that trap heat in the atmosphere are often called greenhouse gases. This section of the EPA Climate Change Site provides information and data on emissions of greenhouse gases to Earth’s atmosphere, and also the removal of greenhouse gases from the atmosphere. For more information on the science of climate change, please visit EPA's climate change science home page.

DOLPHINS WERE SAVED BY BEACH GOERS IN BRAZIL
Dolphins in Arraial do Cabo beach in Rio de Janeiro, may have gone astray due to fishing net, or sonar effect, or just were washed ashore by a strong current.
An expert in dolphins said that pulling them up by their flippers could damage some of their bones; and that an expert should have been brought to the beach to save those lovely mammals. He probably does not know that nor would be easy to find an expert in dolphins neither to bring him/her quickly to the beach, while the dolphins would struggle for survival in shallow water.
Please watch the video and conclude by yourselves if the alternative of bringing an expert would be advisable!
