Deutsche Bank has erected a seven-story sign in the heart of New York City that ticks off the tons of carbon dioxide being emitted into the atmosphere — a public relations move designed to raise awareness of global warming.

The ocean is warming about 50 per cent faster than reported two years ago, according to an update of the latest climate science. A report compiling research presented at a science congress in Copenhagen in March says recent observations are near the worst-case predictions of the 2007 report by the United Nations' Intergovernmental Panel on Climate Change.

NASA has successfully blasted two probes into space on a landmark lunar exploration mission to scout water sources and landing sites in anticipation of sending mankind back to the moon in 2020. The launch marked "America's first step in a lasting return to the moon," a NASA official said moments after a rocket carrying the probes launched at 5:32 pm (2132 GMT), one day after the US space agency scrubbed the shuttle Endeavour launch for the second time in a week because of a nagging hydrogen fuel leak.

A team of NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University, and the University of Michigan is forecasting that the “dead zone” off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be one of the largest on record. The dead zone is an area in the Gulf of Mexico where seasonal oxygen levels drop too low to support most life in bottom and near-bottom waters.

Based on new research that shows shredded tires may release arsenic, lead and mercury into the products they are used in, the EPA is examining the safety of using them in applications such as playground surfacing.

Advocates for the cement industry in the U.S. and environmentalists are facing off in hearings this week as federal regulators call for comment on new rules to limit emissions from the energy-intensive kilns that are core to the business.

Scientists have been puzzled by the lack of sunspots on the surface of the sun. But now they may have figured out an explanation.

Extracting carbon dioxide from power plant exhaust and storing it underground may be the only hope to avoid a climate change catastrophe caused by burning fossil fuels

Pollution in the Mekong River has pushed the local population of Irrawaddy dolphins to the brink of extinction, a new report by WWF has revealed.

Sewage treatment plants fail to remove artificial sweeteners completely from waste water. What’s more, these pollutants contaminate waters downstream and may still be present in our drinking water.

A Senate committee on Wednesday approved an energy bill that would open large tracts of the Gulf of Mexico to oil and gas drilling and provide federal loan guarantees for a gas pipeline project in Alaska. The measure, which cleared the Senate Energy and Natural Resources Committee on a 15-to-8 vote, would also require utilities to produce up to 15 percent of electricity from renewable sources like wind and solar power by 2021. That standard is somewhat weaker than one in a House energy and climate change bill that is headed for a floor vote as early as next week.

A press conference was held Tuesday to discuss a climate study prepared by the U.S. Global Change Research Program. The study lays out the effects of global warming on specific U.S. regions and sectors, and calls for immediate action.

Although worlds apart, the way fish learn could be closer to humans' way of thinking than previously believed, suggests a new research study.

Russia will create a new 1.5 million hectare park in the Arctic, a central area for the Barents and Kara Sea polar bear populations.

Temuco, with a population of 300,000, has the fourth most polluted air in the country, according to local media. The burning of firewood for heating, cooking, and other uses is the main source of soot particulates, known as "black carbon," that enter the air at levels 150 percent higher than the national standard and more than four times the World Health Organization's recommended limit.

Engineering our climate to stop global warming may seem like science fiction, but at a recent National Academy of Sciences meeting, scientists discussed some potential geoengineering experiments in earnest.

The US Federal government released a major report today. The report summarizes the science and the impacts of climate change on the United States, now and in the future. It focuses on climate change impacts in different regions of the U.S. and on various aspects of society and the economy such as energy, water, agriculture, and health. The report is the work of 12 federal agencies including the EPA, DOD,COMMERCE, NASA, and others.It’s written in plain language, with the goal of better informing public and private decision making at all levels.

Besides the obvious reason, TNT is not good for you. But grass, it turns out, might be dynamite for the problem.

As the United States debates how it should tackle climate change, "Big Business" has generally received the most political attention. Small companies are mostly disengaged from the climate debate, businesses advocates say, yet environmentally conscious, small enterprises could become influential supporters of climate legislation.

A blue butterfly died out in Britain 30 years ago because of disruptions to a life cycle that includes pretending to be an ant, according to a study published Tuesday that points to smarter ways to protect wildlife.
