With 7 billion people in the world today and 9 billion by 2050, we must invest in development that will meet the growing demands for food, water and energy.
The OECD publication Putting Green Growth at the Heart of Development suggests that these investments could define a path for inclusive growth and sustainable development by focusing on people’s needs and prospects while respecting the environment. It also gives examples of developing countries’ successful initiatives to do so.
Highlighting the nature of the challenges and opportunities in this field, Angel Gurría, OECD Secretary General, said “putting green growth at the heart of the development agenda requires real political leadership to instill change at international, national and local levels.”

For the first time in human history, concentrations of the greenhouse gas carbon dioxide (CO2) could rise above 400 parts per million (ppm) for sustained lengths of time throughout much of the Northern Hemisphere as soon as May 2013.
To provide a resource for understanding the implications of rising CO2 levels, Scripps Institution of Oceanography at UC San Diego is providing daily updates of the “Keeling Curve,” the record of atmospheric CO2 measured at Hawaii’s Mauna Loa.
These iconic measurements, begun by Charles David (Dave) Keeling, a world-leading authority on atmospheric greenhouse gas accumulation and Scripps climate science pioneer, comprise the longest continuous record of CO2 in the world, Continue reading

Berlin aims to be climate neutral in the year 2050.
A team of experts from the Potsdam Institute for Climate Impact Research (PIK), on behalf of the Berlin Senate, the executive body governing the city of Berlin, will work to show how this goal can be achieved.
Hans Joachim Schellnhuber, PIK director, said “if the German capital is pioneering in climate protection to maintain the 2°Celsius limit with regard to global warming, nations will have to act as well as bold local authorities.”
Michael Müller, Berlin Senator for Urban Development and the Environment, highlighted the significance of this feasibility study.
“Berlin has to be a highly energy-efficient and modern city and Continue reading

In today’s society, the word “sustainable” has become practically meaningless, with most sustainable products just a step less bad than conventional alternatives.
Because of the power of “sustainababble,” the world has largely ignored the rich spectrum of political, cultural, and technological changes that would set us on the path to a truly sustainable future.
Although the science of sustainability is clearer than ever, we still face the question of whether transforming our society into one guided by sustainability is even possible.

Climate change may lead to bumpier transatlantic flights by the middle of the 21st century, suggests work published in the letter “Intensification of winter transatlantic aviation turbulence in response to climate change‘ in the journal Nature Climate Change.
The study reports that clear-air turbulence is likely to change significantly with the doubling of carbon dioxide from pre-industrial levels, which is expected in the next 40 years.
Dr Paul Williams from the University of Reading and Dr Manoj Joshi from the University of East Anglia‘s School of Environmental Sciences used climate simulations to investigate changing conditions in the transatlantic flight corridor in response to carbon dioxide levels.
Clear-air turbulence is linked to atmospheric jet streams, which are projected to strengthen with climate change. Continue reading

The world has suffered from severe regional weather extremes in recent years, such as the heat wave in the United States in 2011 or the one in Russia 2010 coinciding with the unprecedented Pakistan flood.
Behind these devastating individual events there is a common physical cause according to scientists of the Potsdam Institute for Climate Impact Research (PIK).
Their study published in the US Proceedings of the National Academy of Sciences suggests that man-made climate change repeatedly disturbs the patterns of atmospheric flow around the globe’s Northern hemisphere through a subtle resonance mechanism.
“An important part of the global air motion in the mid-latitudes Continue reading

Climate scientists have shown through their research that the ongoing rise in global temperature will cause the sea level to rise, which will drown coastal communities, and cause severe weather, which will kill many people.
So why don’t politicians act on these findings?
Social scientist Stellan Vinthagen shows that today’s power relations prohibit change.
The world is heading towards a catastrophic global average temperature increase of 4°Celsius.
The consequences are a rising sea level, droughts, floods and lethal heat waves.
Stellan Vinthagen, Associate Professor of Sociology at University West in Sweden, states that it is the prevailing power structures that make politicians paralyzed. And he sees social scientists as a key group for this to change. Continue reading

The research, published in the paper ‘Projected Atlantic hurricane surge threat from rising temperatures‘ in ‘Proceedings of the National Academy of Sciences of the USA (PNAS) concludes that the threat from hurricane-induced storm surges in the Atlantic will increase significantly as global temperatures rise.
Storm surges are localised increases in sea level, brought about by hurricanes, that can devastate coastal populations.

To fight climate change, corporations and consumers should have to pay for emitting greenhouse gases, speakers at a recent Stanford University energy conference agreed, but other government actions are still needed.
Several countries, as well as the state of California, have instituted a price on carbon, either by taxing greenhouse gas emissions directly or by issuing a limited number of emission permits that utilities and other heavy polluters must purchase.
Many supporters of putting a price on carbon insist that governments should otherwise drop all other climate change rules and let the free market do its work once the tax takes effect.
