Talk at Cancun is of 2 degrees Celsius – even 1.5 degrees would have effects lasting centuries

12/09/2010 – Even global warming of just 1.5 degrees Celsius would have consequences for centuries. The oceans store elevated temperatures for a longer time than was previously thought. This is due to a change in ocean-atmosphere heat exchange, scientists of the Potsdam Institute for Climate Impact Research discovered. Heat in lower oceanic layers is trapped by a cooling of upper layers, says a study which is about to be published in the journal Earth System Dynamics. Even if it would work to cool down the planet by extracting CO2 from the atmosphere, according to the calculations this cooling would be ten times slower than the currently observed temperature rise by greenhouse gases. Steric sea level rise under this scenario would continue for 200 years after the peak in surface air temperatures.

Global Warming could cool down temperatures in winter

Global Warming could cool down temperatures in winter

11/16/2010 – The overall warming of the earth's northern half could result in cold winters. The shrinking of sea-ice in the eastern Arctic causes some regional heating of the lower levels of air – which may lead to strong anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, a study recently published in the Journal of Geophysical Research shows. “These anomalies could triple the probability of cold winter extremes in Europe and northern Asia,” says Vladimir Petoukhov, lead author of the study and climate scientist at the Potsdam Institute for Climate Impact Research. “Recent severe winters like last year’s or the one of 2005-06 do not conflict with the global warming picture, but rather supplement it.”

Climate scientists want to better understand societal processes

11/12/2010 – Climate research needs a reorientation towards giving greater weight to the human factor, some leading figures of the international scientific community wrote in an appeal published in "Science" this Thursday. Economic, social and cultural processes have to be better integrated in models of earth system analysis that are typically geophysical. The usefulness of sustainability research is the main focus. "Research has to better understand how people respond to environmental change", Hans Joachim Schellnhuber says, director of the interdisciplinary Potsdam Institute for Climate Impact Research. "To achieve progress, we need a new balance of natural and social sciences." The physicist Schellnhuber is one of the authors of the appeal.

Land plants process 15 percent of total atmospheric carbon dioxide each year

Land plants process 15 percent of total atmospheric carbon dioxide each year

07/06/2010 - Terrestrial ecosystems draw about 123 billion tonnes of carbon (450 billion tonnes of carbon dioxide, CO2) from the atmosphere each year. Based on worldwide local measurements and data-driven model simulations, an international team of researchers led by Christian Beer of the Max Planck Institute for Biogeochemistry in Jena has for the first time provided an observation-based estimate of the largest global flux of carbon between land and atmosphere and of its climate dependencies. The researchers evaluated the result against spatially explicit process models including the leading model LPJmL from PIK. Tropical ecosystems such as rain forests and savannas account for almost two thirds of the CO2 uptake, they report in an article published by the journal “Science” on the “Science Express” web site today.

Conscious choice of food can substantially mitigate climate change

06/28/2010 - Reducing the consumption of meat and dairy products and improving agricultural practices could decrease global greenhouse gas emissions substantially. By 2055 the emissions of methane and nitrous oxide from agriculture could be cut by more than eighty percent, researchers of the Potsdam Institute for Climate Impact Research find. The results of the modelling study have recently been published in the journal “Global Environmental Change”.

Atlantic surface circulation qualifies as ‘tipped’ element

Atlantic surface circulation qualifies as ‘tipped’ element

06/25/2010 - An abrupt and persistent strengthening of the ocean currents forming the Atlantic subpolar gyre could have resulted from a large freshwater flooding event 8,200 years ago. New climate model simulations resolve the contradiction of increased freshwater inflow and enhanced deep water formation in the North Atlantic. The enhanced surface circulation could contribute to the climatic stability since the last ice age, the researchers suggest in the American Geophysical Union’s electronic journal “G-Cubed”.

Copenhagen Accord misses 2° C climate target

04/22/2010 - The current national emissions-reduction pledges accompanying the Copenhagen Accord will not limit global warming to two degrees Celsius. In fact, they imply a global mean temperature increase of more than three degrees Celsius this century. This is reported by a team of researchers led by Joeri Rogelj and Malte Meinshausen of the Potsdam Institute for Climate Impact Research in the current edition of the journal “Nature”.

Europe could create a 100% renewable electricity supply by 2050

Europe could create a 100% renewable electricity supply by 2050

03/29/2010 – Renewable energy sources could be used at scale by 2050 if supported by an efficient European transmission grid and a single European power market united with similar grids and markets in North Africa. This is shown in a new report released last week by PricewaterhouseCoopers. A group of energy and climate experts from the company in collaboration with researchers of the Potsdam Institute for Climate Impact Research (PIK), the International Institute for Applied Systems Analysis (IIASA) and the European Climate Forum (ECF) have examined possible transformation paths for the European and North African power sector. A transformation of the power sector based on one hundred percent renewables would address energy security and supply concerns while decarbonising electricity generation and at the same time reduce energy poverty, the report says.

Technological options are critical for economic viability of 2°C climate target

Technological options are critical for economic viability of 2°C climate target

03/15/2010 - Tapping renewable energy sources, capturing and storing of industrial emissions of carbon dioxide and improving energy efficiency are pivotal for holding the increase in global temperature below two degrees Celsius. In a special issue of “The Energy Journal”, a team of researchers of the Potsdam Institute for Climate Impact Research (PIK) and four other European institutions reports that atmospheric concentrations of greenhouse gases can be stabilized at correspondingly low levels at moderate costs. However, costs, as well as the dependency on specific technologies, increase with the chances to achieve the 2°C target.

Weakening Sun would hardly slow global warming

Weakening Sun would hardly slow global warming

03/10/2010 - A new Grand Minimum of solar activity would decrease the rise of global mean temperature caused by human greenhouse gas emissions only marginally. A new modelling study by researchers of the Potsdam Institute for Climate Impact Research, published online today in the journal Geophysical Research Letters, finds a temperature offset of at most 0.3 degrees Celsius until the end of the century. This is less than ten percent of the temperature rise projected under “business as usual” scenarios of the Intergovernmental Panel on Climate Change (IPCC).
