World map showing risk assessment of future changes in potential tree cover. (A) Illustration of expected losses in potential tree cover by 2050, under the “business as usual” climate change scenario (RCP 8.5), from the average of three Earth system models commonly used in ecology (cesm1cam5, cesm1bgc, and mohchadgem2es). (B) Quantitative numbers of potential gain and loss are illustrated by bins of 5° along a latitudinal gradient. Graphic: Bastin, et al., 2019 / Science

Expert reaction to study looking at trees, carbon storage, and climate change – “It is time to stop suggesting there is a ‘nature-based solution’ to ongoing fossil fuel use. There isn’t. Sorry.”

4 July 2019 (Science Media Centre) – A new study, published in Science, reports on the capacity for trees to reduce atmospheric carbon levels. Dr James Borrell, Researcher at the Royal Botanic Gardens, Kew, said: “Global forest restoration clearly has remarkable potential to address climate change, but restoring forest on this scale is a significant […]

As oceans warm, microbes could pump more carbon dioxide back into the air

By Kevin Krajick 29 April 2019 (Columbia University) – The world’s oceans soak up about a quarter of the carbon dioxide that humans pump into the air each year — a powerful brake on the greenhouse effect. In addition to purely physical and chemical processes, a large part of this is taken up by photosynthetic plankton as they incorporate carbon into their […]

Scientists warn NSW tree-planting scheme does more harm than good – “The main goal of the project is to actually plant as many trees as you can fit into the ground”

By Jonathan Hair 26 May 2019 (ABC News) – There are fears national parks in NSW are being damaged by a revenue-making tree-planting scheme, after revegetation works were carried about in the Capertee National Park. About three hours’ drive west of Sydney, Capertee National Park was a working cattle property until 2010, when it was […]

Scientists say halting deforestation “just as urgent” as reducing emissions – “Our planet’s future climate is inextricably tied to the future of its forests”

By Oliver Milman 4 October 2018 (The Guardian) – The role of forests in combating climate change risks being overlooked by the world’s governments, according to a group of scientists that has warned halting deforestation is “just as urgent” as eliminating the use of fossil fuels. Razing the world’s forests would release more than 3 […]

In southeastern U.S., industrial-scale logging drives loss of forest cover – “A highly degraded ecosystem of forests that just get continuously logged over and over again”

By Christina Hoover Moorehead 25 July 2018 (ChavoBart Digital Media) – The southeastern United States is losing trees fast. Between 2000 and 2012, trees in the region were cut up to four times faster than in South American rainforests. Smith: “In the southeastern U.S., what’s driving the loss of forest cover is industrial-scale logging.”That’s Danna […]

Earth Overshoot Day 2018 is August 1, the earliest date since ecological overshoot started in the early 1970s – “Our current economies are running a Ponzi scheme with our planet”

OAKLAND, California, 13 June 2018 (Global Footprint Network) – On August 1, humanity will have used nature’s resource budget for the entire year, according to Global Footprint Network, an international research organization that has pioneered the Ecological Footprint resource accounting metric. The Ecological Footprint adds up all of people’s competing demands for productive areas, including […]

Forests “essential” for the future, UN agriculture chief spells out in new report

6 July 2018 (UN News) – Time is running out for the world’s forests, warns a new report by the United Nations agriculture agency, urging governments to foster an all-inclusive approach to benefit both trees and those who rely on them.Halting deforestation, managing forests sustainably, restoring degraded forests and adding to worldwide tree cover all […]

2017 was the second-worst year on record for global deforestation – “We are trying to put out a house fire with a teaspoon”

By Damian Carrington, Niko Kommenda, Pablo Gutiérrez, and Cath Levett 27 June 2018 (The Guardian) – The world lost more than one football pitch of forest every second in 2017, according to new data from a global satellite survey, adding up to an area equivalent to the whole of Italy over the year.The scale of […]

UN forest accounting loophole allows CO2 underreporting by EU, UK, US – “There may not be a pathway to 1.5 degrees anymore — at all. Carbon capture and storage is a fantasy.”

By Justin Catanoso 2 May 2018 (Mongabay) – For the past ten years, Mary Booth, an ecologist with the Partnership for Policy Integrity in Pelham, Massachusetts, has immersed herself in the complex, nuanced, politically charged world of international carbon emissions accounting models as if the planet’s fate depends on it. In many ways, it does. […]

Why current negative-emissions strategies remain “magical thinking”

21 February 2018 (Nature) – Decarbonization of the world’s economy would bring colossal disruption of the status quo. It’s a desire to avoid that change — political, financial and otherwise — that drives many of the climate sceptics. Still, as this journal has noted numerous times, it’s clear that many policymakers who argue that emissions […]
