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 …

Energy demand around the world grew by 2.3% over the past year, marking the most rapid increase in a decade, according to the report from the IEA. Fossil fuels filled nearly 70%

Several publications report on the International Energy Agency (IEA)’s latest annual report on global carbon emissions. The Washington Post focuses on the “grim findings”, which show “that not only are planet-warming CO2 emissions still increasing, but the world’s growing thirst for energy has led to higher emissions from coal-fired power plants than ever before”. The Post adds: “Energy demand around …

Stiglitz urges joint EU-China trade sanctions against the US on climate change

By Frédéric Simon | EURACTIV.com Mar 28, 2019 Joseph Stiglitz argues that Europe and China should consider climate-related trade sanctions against the US, saying there is a legal precedent at the World Trade Organisation providing them with the legal grounds to do so. [EPA/GIAN EHRENZELLER] Languages: Deutsch  Nobel Prize laureate Joseph Stiglitz has called on Europe and China to join forces against the United States …

Evidence of Human-Caused Climate Crisis Has Now Reached ‘Gold Standard’-Level Certainty, Scientists Say

This article was originally published by Futurism. Read the original article. New analysis of 40 years’ worth of satellite data shows that it’s a near-certainty that humanity is actively causing global climate change. Climate deniers often claim, in the face of overwhelming evidence, that the planet is heating up and natural disasters are becoming more intense and common just because that’s the way it is …
