Methane Gas Flares May be Caused by Natural Processes

Methane hydrates are fragile. At the sea floor the ice-like solid fuel composed of water and methane is only stable at high pressure and low temperature. In some areas, for instance in the North Atlantic off the coast of Svalbard, scientists have detected gas flares regularly.

Warming Global Oceans Maybe Targeting Antarctica's Pine Island Glacier

Pine Island Glacier is one of the biggest routes for ice to flow from Antarctica into the sea. The floating ice shelf at the glacier's tip has been melting and thinning for the past four decades, causing the glacier to speed up and discharge more ice.

Comfortable Water Temperature for Washing Hands Can Help Lower Greenhouse Gas Emissions

Signs in many bathrooms across the country recommend washing hands in hot or warm water. In fact, if Americans could be persuaded en masse to use a comfortable water temperature when washing their hands, it could prevent the annual greenhouse gas emissions totaling the equivalent of the United States’ lead industry or the entire output of a small nation such as Barbados.

New Long-Lived Greenhouse Gas Discovered in the Atmosphere

Scientists from U of T's Department of Chemistry have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical – perfluorotributylamine (PFTBA) – is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate.

Global Warming Shrinks Massive Plates of Sea Ice in the Arctic Ocean

For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: In 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980.

Previous Studies Underestimate Emissions from Cattle Farming and Fossil Fuel Production

The United States emits 1.5 times more of the greenhouse gas methane than leading estimates, according to a new study by a team of Earth and atmospheric scientists.

Global Emissions Due to Fossil Fuel Set to Reach Unprecedented Level in Human History

Global emissions of carbon dioxide from the combustion of fossil fuels will reach 36 billion tonnes for the year 2013 – a level unprecedented in human history – according to the annual Global Carbon Budget, produced by an international team of researchers including Dr Jo House of the Cabot Institute at the University of Bristol.

Natural Reserve System’s Climate Monitoring Network Helps Answer Climate Questions

Climate shapes the life around us. At the poles, thick fur coats and layers of blubber enable animals to withstand bitter cold. In deserts, small and drought-resistant leaves help plants survive extreme aridity.
