11Issues related to the management of energy consumption and energy efficiency in municipal buildings are the main theme of a joint ISEDC/UNDP/GEF training course for young international specialists, which will be held in July this year.

The crucial changes that took place in the modern world in the recent decades, the rapid development of scientific knowledge and information technologies pose absolutely new problems for the world community. Under these conditions, the role of professional education with the use of practical aspects grows enormously.

forest8On the International Day of Forests, United Nations Secretary-General Ban Ki-moon is calling on governments, businesses, civil society and other partners to adopt holistic policies and practices to protect, restore and sustain healthy forests.

“Investing in forests is an insurance policy for the planet,” said Mr. Ban in a message on the day, marked annually on 21 March.

earth1In a comprehensive new study published in the journal Nature Climate Change, researchers propose a limit to future greenhouse gas emissions—or carbon budget—of 590-1240 billion tons of carbon dioxide from 2015 onwards, as the most appropriate estimate for keeping warming to below 2°C, a temperature target which aims to avoid the most dangerous impacts of climate change.

The study finds that the available budget is on the low end of the spectrum compared to previous estimates—which ranged from 590 to 2390 billion tons of carbon dioxide for the same time period—lending further urgency to the need to address climate change.

arctic5Results from a new climate reconstruction of how Antarctica's ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought.

Details appear in two papers in the current Proceedings of the National Academy of Sciences.
