No plain sailing for marine life as climate warms
Direct effects of climate warming on biodiversity pose a serious conservation challenge for marine life, according to new research published today in Science. Marine life may need to relocate faster than land species as well as speed up alterations in the timing of major life cycle events. This challenges previous thinking that marine life in the ocean would respond more gradually than species ...

Ocean Wind Wave Climate Responses to Wintertime North Atlantic Atmospheric Transient Eddies and Low-Frequency Flow
Atmospheric transient eddies and low-frequency flow contributions to the ocean surface wave climate in the North Atlantic during boreal winter are investigated (1980 - 2016). We conduct a set of numerical simulations with a spectral wave model (WAVEWATCH III) forced by decomposed wind fields derived from the ERA-Interim reanalysis (0.7° horizontal resolution). Synoptic-scale processes (2-10 ...

Carbon neutral goal for aviation won’t neutralise its climate impact
Latest research shows that the International Civil Aviation Organisation (ICAO) and industry goal of carbon neutral growth in 2020 will not, as the name might suggest, neutralise aviation’s climate impact. ICAO is meeting this week in Montreal to attempt to conclude 16 years of negotiations on a set of measures to tackle climate-change emissions from international aviation. Even if ICAO ...

Climate is warming – despite `ups and downs`
“Despite 2010 being a very warm year globally, the severity of the 2009-2010 northern winter and a wetter and cooler Australia in 2010 relative to the past few years have been misinterpreted by some to imply that climate change is not occurring,” Mr Hunt said. “Recent wet conditions in eastern Australia mainly reflect short-term climate variability and weather events, not ...

Cooling without climate warming: Environment MEPs recommend F-gas bans
Use of climate-unfriendly fluorinated gases should be banned in new air-conditioning appliances and refrigerators by 2020, according to a vote on draft legislation in the Environment Committee on Wednesday. Overall use of potent hydrofluorocarbon (HFC) greenhouse gases should be reduced 84% by 2030, MEPs say. Following bans on chlorofluorocarbons (CFCs) in the 1980s to stop depletion of the ...

Sea level rise of 3.3 metres from West Antarctic Ice Sheet collapse
The West Antarctic Ice Sheet (WAIS) is vulnerable to even moderate climate change and could collapse rapidly, pushing up sea levels around the world. A new study concludes that the global sea level rise (SLR) from the collapse of the WAIS will not be as high as predicted by previous studies, but still substantial at around 3.3 metres on average. Previous studies have suggested that if the WAIS ...

Spring Furies Unleashed by La Niña (et. al.)
After a long, cold winter, spring has finally arrived in the northern hemisphere. People who are not weather buffs tend to think of spring in terms that are gentle and sweet, like fluffy baby bunnies and daffodils nodding in a gentle shower. But when a weather buff thinks of spring, the images are likely to be a lot more ferocious -- like tornadoes, floods, hurricanes and thunderstorms. Spring, ...
