With the COP Climate conference in Glasgow only a few months away, the ambitions of the Paris Agreement and the importance of taking action at the national level to reach global climate goals is returning to the spotlight. IIASA researchers and colleagues have proposed a novel systematic and independent scenario framework that could help policymakers assess and compare climate policies and long-term strategies across countries to support coordinated global climate action.
The Paris Agreement defines a long-term temperature goal for international climate policy: holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C . Its achievement critically depends on actions and policymaking at the regional, national, and subnational level

No less than 10 IIASA researchers have made it onto the Reuters Hot List – the media giant’s ranking of the world’s most influential climate scientists – with IIASA Energy, Climate, and Environment Program Director, Keywan Riahi, claiming the top spot.
The Reuters Hot List of climate scientists identifies the world’s 1,000 most influential scientists, using a combination of three rankings. These are based on the number of papers a scientist has published on topics related to climate change; how often those papers are cited by other scientists in similar fields of study; and how often those papers are referenced on other channels including the lay press, social media, and policy papers.

Although violent and unpredictable, stellar flares emitted by a planet s host star do not necessarily prevent life from forming, according to a new Northwestern University study.
Emitted by stars, stellar flares are sudden flashes of magnetic imagery. On Earth, the sun s flares sometimes damage satellites and disrupt radio communications. Elsewhere in the universe, robust stellar flares also have the ability to deplete and destroy atmospheric gases, such as ozone. Without the ozone, harmful levels of ultraviolet (UV) radiation can penetrate a planet s atmosphere, thereby diminishing its chances of harboring surface life.
By combining 3D atmospheric chemistry and climate modeling with observed flare data from distant stars, a Northwestern-led team discovered that stellar flares could play an important role in the long-term evolution of a planet s atmosphere and habitability.
