Capping warming at 2 degrees: New study details pathways beyond Paris

 FR,US
Even if countries adhere to the Paris climate agreement hammered out last fall, capping global warming at 2 degrees Celsius (4 degrees Fahrenheit) would likely require net zero greenhouse gas emissions by 2085 and substantial negative emissions over the long term, according to an in-depth analysis by scientists at the National Center for Atmospheric Research (NCAR) in Boulder,

Forecasting Climate, with Help from the Baobab Tree

To improve climate forecasts, scientists study the complex interactions and mechanisms within the climate system. But they also need to hear from potential users of climate information, such as farmers, to get a better understanding of how people may use that information in their decision

Saturn moon Enceladus’ ice shell likely thinner than expected

A vast ocean of water beneath the icy crust of Saturn’s moon Enceladus may be more accessible than previously thought, according to new research. A new study has revealed that near the moon’s poles, the ice covering Enceladus could be just two kilometers (one mile) thick—the thinnest known ice shell of any ocean-covered moon. The discovery not only changes scientists’ understanding of Enceladus’ structure, but also makes the moon a more appealing target for future exploration, [...]

The challenge is that the scientists have had great difficulty finding evidence that we are indeed on the plume. Amicable discussions often take place in R/V Falkor’s Dry Lab or the Library. Joseph might think that the satellite images give evidence a certain location is within the reaches of the plume, but oceanographer Annalisa Bracco might reply the data could also be related to coastal upwelling, and not the plume

This week’s imaggeo on Monday’s photography is Godrevy Lighthouse in North Cornwall (UK) experiencing the full force of the 2013/14 British Winter Storms which caused damage across the south west of the country. During mid-December 2013 to mid-February 2014 the UK was hit by six major storms bringing record precipitation, strong winds, huge waves and generating overall hazardous conditions. Despite the overall consensus being that these winter months were very wet, the question arose: did [...]

Ever since it was discovered wrapped in the folds of Tutankhamun's mummy in 1925, an ancient Egyptian dagger has puzzled historians. How did the boy pharaoh's craftsmen make an iron blade of such quality that it survived more than 3,000 years inside a sarcophagus without turning to rust?Scientists have now reached an extraterrestrial answer: the dagger was forged from the metal of a fallen meteorite. A team of Egyptian and Italian researchers used X-rays to analyse the iron in the knife and [...]

You can't mystify scientists of the Earth with questions of latitude. I had numerous answers pretty darn quick about why this stop sign reveals my location. The sign pole is casting no shadow! The only way that can happen is if the sun is directly overhead, and that can only happen if one is within 23 degrees of the equator, and only at noon. I have never thought to seek such a picture on

Guest post by Emmanuel Vincent While 2016 is on track to easily surpass 2015 as the warmest year on record, some headlines, in otherwise prestigious news outlets, are still claiming that “2015 Was Not Even Close To Hottest Year On Record” (Forbes, Jan 2016) or that the “Planet is not overheating…” (The Times of London,

The history of Greenland’s snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the passing years. Using this ancient record, scientists are attempting to reconstruct how Arctic precipitation fluctuated over the past several millennia, potentially influencing the size of the Greenland Ice Sheet as the Earth warmed and

Earth system scientists from the University of California, Irvine have taken water samples from the north Pacific, north and south Atlantic, and Arctic oceans in search of repositories of black carbon, soot from burning biomass and diesel engines, among other sources. They’ve found considerably less of the material than expected, and they’ve discovered that it exists in at least two varieties, a younger pool closer to the ocean’s surface that is absorbed into the environment in a roughly [...]

The EGU General Assembly was bigger than ever this year. Over 16,500 people attended more than 500 sessions. Although many sessions featured policy-relevant science, the short course entitled ‘Working at the science policy interface‘ focused purely on the role of scientists with the policy landscape. For those of you that couldn’t attend, this month’s GeoPolicy post takes a closer look at what was discussed. The short course consisted of three panellists; Katja Rosenbohm, [...]
