Clean energy grids and electric vehicles key to beating climate change and air pollution
Any uptake in electric vehicle use must be mirrored by the development of clean energy grids to mitigate both climate change and air pollution. That is the key finding of a new study by researchers at the Lawrence Berkeley National Laboratory, California, and Stanford University, California. Published in the IOP Publishing journal Environmental Research Letters, […]

Aviation emissions’ impacts on air quality larger than on climate, study finds
New research from the Massachusetts Institute of Technology (MIT) has quantified the climate and air quality impacts of aviation, broken down by emission type, altitude and location. The MIT team found that growth in aviation causes twice as much damage to air quality as to the climate. Writing today in IOP Publishing’s Environmental Research Letters, […]

New study investigates the important role of Tambora eruption in the 1816 ‘year without a summer’
A new study has estimated for the first time how the eruption of Mount Tambora changed the probability of the cold and wet European ‘year without a summer’ of 1816. It found that the observed cold conditions were almost impossible without the eruption, and the wet conditions would have been less likely. 1816 recorded exceptionally […]

Study offers verdict for China’s efforts on coal emissions
Researchers from China, France and the USA have evaluated China’s success in stemming emissions from its coal-fired power plants (CPPs). CPPs are one of the main contributors to air pollution in China, and their proliferation over the last 20 years has had significant impacts on air quality and public health. These impacts led authorities to […]

Paris Agreement hampered by inconsistent pledges, new research finds
Some countries’ Paris Climate Agreement pledges may not be as ambitious as they appear, a new study has found. The Paris Agreement takes a bottom-up approach to tackling climate change, with countries submitting pledges in the form of nationally determined contributions (NDCs) to greenhouse gas emissions. However, writing today in Environmental Research Letters, researchers from […]

Could climate change make Siberia more habitable?
Large parts of Asian Russia could become more habitable by the late 21st century due to climate change, new research has found. A study team from the Sukachev Institute of Forest, Krasnoyarsk Federal Research Center, Siberian Branch, Russian Academy of Sciences, and the National Institute of Aerospace, USA, used current and predicted climate scenarios to […]

Summer extremes of 2018 linked to stalled giant waves in jet stream
Record breaking heatwaves and droughts in North America and Western Europe, torrential rainfalls and floods in South-East Europe and Japan – the summer of 2018 brought a series of extreme weather events that occurred almost simultaneously around the Northern Hemisphere in June and July. These extremes had something in common, a new study published today […]

NASA study verifies global warming trends
A new study by researchers from NASA has verified the accuracy of recent global warming figures. The team used measurements of the ‘skin’ temperature of the Earth taken by a satellite-based infrared measurement system called AIRS (Atmospheric Infra-Red Sounder) from 2003 to 2017. They compared these with station-based analyses of surface air temperature anomalies – […]
