Avoided deforestation has a high value but is hard to prevent without strong regulation and enforcement

Potential for low-cost carbon dioxide removal through tropical reforestation (Nature Climate Change) Removing CO2 from the atmosphere by planting tropical forests could be a “low cost” way of tackling climate change, a study says. The research estimates that CO2 removal from tropical reforestation could be increased by 5% at a cost of $20 per tonne of CO2. However, “avoided deforestation” – leaving forests …

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 …

Heating and risk of heatwaves are much worse

‘It is horrid’: India roasts under heat wave with temperatures above 120 degrees, 7 June 2019 The Washington Post | Joanna Slater When the temperature topped 120 degrees (49 Celsius), residents of the northern Indian city of Churu stopped going outside and authorities started hosing down the baking streets with water. Churu – home to more than 100,000 people – has …

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 …
