Attribution science for tornadoes and a range of other physical events

The figure below shows how well the effects of climate change on different extreme events are understood. It ranks each type of extreme event based on how well the effects of climate change are understood (the x-axis) and on the extent to which any individual event can be attributed to climate change (the y-axis). Understanding and attribution of climate change …

Climate change visualized: How Earth’s temperature has changed since 1970

Data: NASA GISS; Graphic: Harry Stevens/Axios 2018 was Earth’s 4th-warmest year on record, coming in behind 2016, the planet’s warmest recorded year, as well as 2015 and 2017, according to information released by NOAA, NASA and the U.K. Met Office. Why it matters: The yearly rankings don’t tell the whole story of long-term climate change, since natural variability can still push or …

Trends in plankton communities

DeSmogBlog, May 16, 2019   Share By Olivia Rosane, EcoWatch. Yet another study has shown that glaciers in Antarctica are melting at accelerating rates. Almost 25 percent of the West Antarctic ice shelf is now thinning, and the Pine Island and Thwaites glaciers are losing ice at five times the rate they were in the early 1990s, CNN reported. “In parts of Antarctica, the ice sheet has thinned by …

CO2 hits over 415 ppm

The concentration of carbon dioxide, the main, long-lived greenhouse gas causing global climate change, in Earth’s atmosphere has reached new heights, according to scientists at Scripps Institution of Oceanography. Why it matters: The new reading of 415.26 parts per million (ppm) on May 11 was the first daily baseline at Hawaii’s Mauna Loa Observatory to eclipse 415 ppm. That observatory has …

Part of world’s largest ice shelf melting 10x faster than the rest. Gorillas showing elevated stress levels in months with higher than average temperatures and rainfall

Part of the world’s largest ice shelf is melting 10 times faster than the rest, reports BBC News. A new study of Antarctica’s Ross Ice Shelf, published in Nature Geoscience, reveals that one area is melting due to warm ocean water getting into a cavity under the shelf. The rapidly melting zone is at the front of the Ross Ice …

New climate models predict a warming surge

By Paul Voosen, Science Mag, Apr. 16, 2019 , 3:55 PM New climate models predict a warming surge For nearly 40 years, the massive computer models used to simulate global climate have delivered a fairly consistent picture of how fast human carbon emissions might warm the world. But a host of global climate models developed for the United Nations’s next major assessment of …

The costs of the current business-as-usual path could be more than $2,000 trillion

As National Geographic reported, the “$25 to $70 trillion cost of Arctic warming adds four to six percent to the total cost of climate change—which is estimated to reach $1,390 trillion by the year 2300 if emissions cuts are not better than the Paris Agreement. However, the costs of the current business-as-usual path could be more than $2,000 trillion.” April 23, 2019 by Jake …

Why results from the next generation of climate models matter: higher and faster global heating means less time to make the energy transition

Carbon Brief, 21 March 2019 Prof Stephen Belcher is chief scientist at the UK Met Office; Dr Olivier Boucher is head of the Institut Pierre Simon Laplace (IPSL) Climate Modelling Centre; and Prof Rowan Sutton is director of climate research at the UK National Centre for Atmospheric Science (NCAS), University of Reading. The first results from a new generation of global climate models, which are valuable tools for understanding climate change, are …
