As the USA simmers through its hottest March on record — with more than 6,000 record high temperatures already set this month — a new study released Sunday shows that average global temperatures could climb 2.5 to 5.4 degrees by 2050 if greenhouse gas emissions continue unabated.

Africa has been urged to play an enhanced role in further negotiations on climate change to aid quick consensus building on a number of issues that still needs to be resolved following the Durban Climate Conference last December.

Of important concern to Africa is the review of the long-term temperature goal agreed at the Cancun Conference in Mexico in ensuring that the global goal of temperature rise (2 degrees Celsius) does not expose Africa to unacceptable risks.

ScienceDaily (Mar. 25, 2012) — The past decade has been one of unprecedented weather extremes. Scientists of the Potsdam Institute for Climate Impact Research (PIK) in Germany argue that the high incidence of extremes is not merely accidental. From the many single events a pattern emerges. At least for extreme rainfall and heat waves the link with human-caused global warming is clear, the scientists show in a new analysis of scientific evidence in the journal Nature Climate Change. Less clear is the link between warming and storms, despite the observed increase in the intensity of hurricanes.

Islamabad: Climate Change could cost the economy of Pakistan up to 14 billion dollars annually for natural disasters and other losses, which are almost 5% of the GDP, said former state minister for environment, Malik Amin Aslam.

An "unprecedented" March heat wave in much of the continental United States has set or tied more than 7,000 high temperature records, and signals a warming climate, health and weather experts said on Friday.

While natural climate variability plays a major role, it is the addition of human-spurred climate change that makes this particular hot spell extraordinary, the scientists said in a telephone and web briefing.

The EU has called on European governments to include data on CO2 emissions from farming and forestry in their efforts to tackle climate change.

The draft law on accounting rules is in line with what was agreed at the Durban climate change conference in December.

But the EU does not yet plan to include farming and forestry in its CO2 Emissions Trading Scheme (ETS).

An unprecedented rise in the demand for food, rapid urbanization and climate change are significantly threatening global water supplies, according to a United Nations report released on Monday, which stresses that a radical new approach to managing this essential resource is needed to be able to sustain future consumption levels.

The status of the world’s seabirds has deteriorated rapidly over recent decades and several species and populations are now perilously close to extinction, according to a new review by BirdLife International, a partner of the IUCN Red List of Threatened Species™. Across the globe, commercial fisheries pose the most serious threat to seabirds.

Bursts of torrential rain lash the idyllic white beaches of the Seychelles, where conservationists fear that rare species such as the giant tortoise are at severe risk from climate change.

As changing season patterns bring harsher storms and much longer dry spells, international organisations are helping fight climate change in the tiny nation, the only one in the world where 50 percent of the land is a nature reserve.

Greenland's ice sheet is more sensitive to global warming than previously thought and may already be approaching a critical threshold, researchers in Spain and Germany found.

The ice sheet may lose its ability to grow once warming reaches 1.6 degrees Celsius since pre-industrial times, according to a study today in Nature Climate Change. That's below the previous best estimate of 3.1 degrees, the scientists at Madrid's Complutense University and Germany's Potsdam Institute for Climate Impact Research found.
