Methane hot spot in US is 3x expected size: Study

One area in the southwestern United States is spewing vast amounts of methane, a potent greenhouse gas, into the atmosphere far faster than expected, US space agency researchers said Thursday.

China pledges to cut carbon intensity by 45 pc by 2020
China pledges to cut carbon intensity by 45 pc by 2020

China, the world's biggest emitter of greenhouse gases, has pledged to reduce its carbon emission intensity by 40-45 per cent by 2020 from the 2005 level in a new plan unveiled just ahead of a UN climate summit in New York.

Greenhouse gas levels in atmosphere hit new high
Greenhouse gas levels in atmosphere hit new high

The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide, the World Meteorological Organisation warned today.

Sunderbans mangrove trees losing capacity to absorb CO2: Study

The vast mangrove forest in the Sunderbans is fast losing its capacity to absorb carbon dioxide, one of the main greenhouse gases, from the atmosphere due to rise in the salinity of water, rampant deforestation and pollution, a study has found.

Human-induced water vapour next climate threat

The rising levels of water vapour in the upper troposphere - a key amplifier of global warming - owing to greenhouse gases will intensify climate change impacts over the next decades, scientists said.

Smartphone charging contributes to global warming

A new study has revealed that smartphones charging emits greenhouse gases that cause global warming.

Climate talks: `Raise your voice, not sea level` – UN

The United Nations seized World Environment Day today to demand action on climate change to protect small island states threatened by rising seas, drought and floods.

`Time is running out` as CO2 levels hit new high: UN

Atmospheric carbon dioxide concentrations have crossed a new threshold, the UN`s weather agency said today, highlighting the urgency of curbing man-made, climate-altering greenhouse gases.

Why Antarctica isn`t warming as much as other continents

Researchers have explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts.

Biofuels from corn less beneficial than reported: Study

Biofuels from corn residue may be less beneficial than previously thought as a study has found using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline.

Global warming could be accelerated by permafrost thawing

Researchers have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.

Causes, consequences of global climate warming 56 mn years ago revealed

Researchers are studying the causes and consequences of global climate warming that took place 56 million years ago.

Weather extremes `consistent` with man-made climate change: UN

Extreme events of 2013 like the Philippines` devastating Typhoon Haiyan and drought in Australia were consistent with man-made climate change, the UN`s weather agency said today.

Aerosols in atmosphere tend to weaken hurricanes and cyclones

A new study has shown that aerosols in the atmosphere produced from human activities tend to weaken hurricane or tropical cyclones.

World`s forests could hold 20% more carbon than previously thought: Study

The world`s forests could hold 20 percent more carbon than previously thought, according to a study released on Tuesday.

Urban adaptation may help curb future climate warming

Researchers have suggested that using urban adaptation strategies like green roof, cool roof, and hybrid technologies can help offset not only future climate warming due to urban expansion but also temperature increases driven by greenhouse gases.

New catalyst turns greenhouse gases into useful chemicals

Scientists have discovered a new method to convert harmful greenhouse gases into chemicals which can produce synthetic fuels, while reducing industrial carbon dioxide emissions by up to 40 percent.

New laser scans for greenhouse gases

Researchers have developed a new type of laser that can be used to detect greenhouses gases in the atmosphere.

New laser that can detect disease in your breath!

Here comes an exciting new laser that can detect very low concentrations of gases - paving the way for accurately analysing breath for disease diagnosis and remote sensing of critical greenhouse gases.
