Green economy provides way out of economic and environmental debt

November 22nd, 2012 by United Nations Environment Programme

Action on climate change needs to be scaled-up and accelerated without delay if the world is to have a running chance of keeping a global average temperature rise below 2° Celsius this century. The Emissions Gap Report, coordinated by the UN Environment Programme (UNEP) and the European Climate Foundation, and involving 55 scientists from more […]

World Bank President says a 4°C warmer world must be avoided

November 20th, 2012 by Potsdam Institute for Climate Impact Research

Humans’ emissions of greenhouse gases are breaking new records every year. These emissions are setting the atmosphere on a path towards an average 4°Celsius increase probably by 2100. This would cause risks beyond the experience of our civilization – including heat waves, especially in the tropics, a sea-level rise affecting hundreds of millions of people, […]

World Bank report states climate change is one of the single biggest challenges facing development

November 19th, 2012 by World Bank

The world is barreling down a path to heat up by 4°Celsius by 2100, if the global community fails to act on climate change, triggering a cascade of cataclysmic changes that include extreme heat-waves, declining global food stocks and a sea-level rise affecting hundreds of millions of people, according to a scientific report “Turn Down […]

More accurate climate modelling predicts greater global warming

November 10th, 2012 by The University Corporation for Atmospheric Research

According to analysis by scientists at the National Center for Atmospheric Research (NCAR), climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The report “A Less Cloudy Future: The Role of Subtropical Subsidence in Climate Sensitivity” published in Science, could provide a […]

PWC shows that decarbonisation of global economy far too slow to limit global warming to 2° Celsius

November 5th, 2012 by PwC

The annual rate of reduction of carbon emissions per unit of GDP (or the carbon intensity of the economy) needed to limit global warming to 2°C, has passed a critical threshold according to new analysis from PwC. The carbon intensity of an economy is affected by a country’s fuel mix, energy efficiency, and the proportion […]

Sir Bob Watson, DEFRA Chief Scientific Advisor, speaks about climate change to Channel 4 News

August 24th, 2012 by Channel 4 News

Tom Clarke, Channel 4 News Science Editor, interviews Sir Bob Watson, DEFRA Chief Scientific Adviser, about the peril of human induced climate change. Sir Bob Watson steps down from his role at DEFRA at the end of August 2012.  Professor Ian Boyd has been appointed to replace Sir Bob Watson as DEFRA’s Chief Scientific Adviser.

Expect significant sea level rise unless carbon emissions curtailed

June 24th, 2012 by Potsdam Institute for Climate Impact Research

Sea levels around the world can be expected to rise by several metres in coming centuries, if global warming carries on. Even if global warming is limited to 2° Celsius, global-mean sea level could continue to rise, reaching between 1.5 and 4 metres above present-day levels by the year 2300, with the best estimate being […]

Upward revision of greenhouse gas emission projections increases prospect of greater temperature rise

May 1st, 2012 by PBL Netherlands Environmental Assessment Agency

The United Nations climate negotiations in Cancún in 2010 and earlier in Copenhagen in 2009, called for urgent action to limit global warming to 2° Celsius. In order to reach this climate goal, 42 industrialised countries submitted quantified economy-wide emission reduction targets for 2020, and 45 developing countries submitted nationally appropriate mitigation actions. All these […]

Greenhouse gases altering patterns of rainfall and ocean salinity

April 27th, 2012 by Lawrence Livermore National Laboratory

A clear change in salinity has been detected in the world’s oceans, signaling shifts and acceleration in the global rainfall and evaporation cycle tied directly to climate change. In a paper, ‘The Greenhouse Is Making the Water-Poor Even Poorer‘ published on 27 April 2012 in the journal Science, Australian scientists from the Commonwealth Scientific and […]

WMO reports that last decade saw climate changing more rapidly

March 24th, 2012 by World Meteorological Organization

The World Meteorological Organization’s Annual Statement on the Status of the Global Climate said that 2011 was the 11th warmest since records began in 1850. It confirmed preliminary findings that 2011 was the warmest year on record with a La Niña, which has a cooling influence. Globally-averaged temperatures in 2011 were estimated to be 0.40° […]
