Climate change likely to uproot more Amazon trees

January 18, 20231032 Views

New study connecting extreme thunderstorms and tree deaths suggests the tropics will see more major blowdown events in a warming world Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they’re also subject to intense storms that can cause “windthrow” – the uprooting or breaking of trees. These downed trees decompose, potentially turning a forest from a carbon sink into a carbon source. Members of NGEE-Tropics visit what they named “Blowdown Gardens,” an area that experienced windthrow near one of their field sites in the Amazon.

This is one of the fe...

Deforestation slowed last year — but not enough to meet climate goals

Report finds that most nations are not on track to meet global pledge to protect Earth’s forests Countries are failing to meet international targets to stop global forest loss and degradation by 2030, according to a report. It is the first to measure progress since world leaders set the targets last year at the 26th United Nations Climate Change Conference of the Parties (COP26) in Glasgow, UK. Preserving forests, which can store carbon and, in some cases, provide local cooling, is a crucial part of a larger strategy to curb global warming. The analysis, called the Forest Declaration Assessment, shows that the rate of global deforestation slowed by 6.3% in 2021, compared with the baseline average for 2018–20. But this “modest” progress falls short of the annual 10% cut needed to end...

Deforestation in Brazil’s Amazon surged to record levels for the month of April, nearly doubling the area of forest removed in that month last year -- the previous April record -- preliminary government data showed on Friday, alarming environmental campaigners. In the first 29 days of April, deforestation in the region totaled 1,012.5 sq km (390 sq miles), according to data from national space research agency Inpe. The agency, which has compiled the monthly DETER-B data series since 2015/2016, will report data for the final day of April next week. April is the third monthly record this year, after new highs were also observed in January and February.

UCI researchers reconsider carbon storage with improved climate models, satellite data In a paper published in Nature Communications, a team led by scientists from the University of California, Irvine, using climate models and satellite data, reveal for the first time how protecting tropical forests can yield climate benefits that enhance carbon storage in nearby areas. Many climate scientists use computer simulations to mimic the planet’s climate as it exists today and how it may exist in the future as humanity keeps emitting greenhouse gases. Such models rely on accurate measurements all the moving parts of the climate system, from how much sunlight hits and warms the climate, to the response of forest biomass to changes in temperature, rainfall and atmospheric carbon dioxide leve...

For tree lovers, plantations are a poor substitute for lost forests

* Indian forests squeezed by infrastructure development* With eye on emissions, government backs tree planting* Critics say intensive plantings are a poor substitute For scientist, activist and tree lover Ravi Chopra, it is a painful sight. Where thick forest recently stood, a swathe of bare yellow earth is now dotted with road-building materials and construction workers near his home in India’s Himalayan foothills. “It’s driving us crazy,” said Chopra, who runs an environmental nonprofit in the city of Dehradun, saying thousands of trees had been cut down due to two recent road-widening projects in the area. “We’re going to pay a very heavy price for cutting down our forests,” he warned. Across India, roads, hydroelectric projects and other infrastructure construction too...

Tropical forests turn down the planet’s heat by 1C, scientists find

Tropical forests cool the world by more than 1 degree Celsius, increase rainfall, and shield people and crops from deadly heat, researchers said, showing the climate benefits of trees go beyond sucking planet-warming carbon dioxide out of the air. In a new study released on Thursday, they outlined different ways the Earth, its climate and its inhabitants rely on forests. As every tenth of a degree of warming fuels threats from extreme weather and rising seas, lead author Deborah Lawrence said it is key to “acknowledge that tropical forests have a very important role in maintaining temperatures at a safe level”. Cutting down forests puts at risk the Paris climate accord’s goal of capping the rise in global average temperatures at “well below” 2C and ideally 1.5C above pre-indu...

Deforestation in Brazil’s Amazon rainforest hits record January high

Brazil recorded the most deforestation ever in the Amazon rainforest for the month of January, according to government data on Friday, as destruction continues to worsen despite the government's recent pledges to bring it under control. Deforestation in Brazil's Amazon totalled 430 square kilometers (166 square miles) last month, five times higher than January 2021, according to preliminary satellite data from government space research agency Inpe. That's the highest for January since the current data series began in 2015/2016, equal to an area more than seven times the size of Manhattan.

In last 15 years, deforestation made outdoors unsafe for millions

The tropics is becoming hotter due to a combination of warming associated with deforestation and climate change—and that can reduce the ability of outdoor workers to perform their jobs safely. Researchers reporting in the journal One Earth on December 17 estimate how many safe working hours people living in the tropics have lost due to local temperature change associated with loss of trees during the past 15 years. “There is a huge disproportionate decrease in safe work hours associated with heat exposure for people in deforested locations versus people in forestated locations just over the past 15 or 20 years,” says first author Luke Parsons, a climate researcher at Duke University. “There is a small amount of climate change that has happened over the same 15-year period, but the incr...

Indigenous leaders push new target to protect Amazon from deforestation

Indigenous groups urged world leaders on Sunday to back a new target to protect 80% of the Amazon basin by 2025, saying bold action was needed to stop deforestation pushing the Earth's largest rainforest beyond a point of no return. Amazonian delegates launched their campaign at a nine-day conference in Marseille, where several thousand officials, scientists and campaigners are laying the groundwork for United Nations talks on biodiversity in the Chinese city of Kunming next year.

Nolan Paquette started working part-time at his local sawmill more than 20 years ago while still at school, pushing a broom on the clean-up team. Now 38, Paquette drives trucks and operates machinery at the same Western Forest Products-owned mill in Duke Point, Nanaimo, the third generation of his family to work in forestry on British Columbia’s Vancouver Island. He is one of 38,000 workers in Canada’s westernmost province whose job, according to the industry, depends on the logging of towering old-growth trees, such as cedars, Douglas firs and western hemlocks aged at least 250 years, and in some cases more than a thousand. The dispute over felling British Columbia’s ancient forests has been thrust into the limelight by a months-long blockade of private logging company Teal Jones i...
