Suspension of Soy moratorium could open up area of rainforest the size of Portugal to destruction
Forests have historically acted as a reliable planetary thermostat. They regulate Earth’s temperature by removing carbon dioxide (CO2) from the atmosphere and locking it in trees, roots and soil — carbon that is emitted if trees are cut down. In a typical year, forests and other vegetation absorb roughly 30% of the carbon that humans emit from burning fossil fuels — a vital climate service performed at virtually no cost by trees around the world, from tropical rainforests to temperate and boreal forests.

‘We are perilously close to the point of no return’: climate scientist on Amazon rainforest’s future
(29/06) - Jonathan Watts,Carlos Nobre,For more than three decades, Brazilian climate scientist Carlos Nobre has warned that deforestation of the Amazon could push this globally important ecosystem past the point of no return. Working first at Brazil’s National Institute for Space Research and more recently at the University of São Paulo, he is a global authority on tropical forests and how they could be restored.
Brazil records 62% jump in area burned by forest fires: monitor
Identifying the socio-economic drivers behind greenhouse gas emissions is crucial to design mitigation policies. Existing studies predominantly analyze short-term CO2 emissions from fossil fuels, neglecting long-term trends and other GHGs. We examine the drivers of all greenhouse gas emissions between 1820–2050 globally and regionally. The Industrial Revolution triggered sustained emission growth worldwide—initially through fossil fuel use in industrialized economies but also as a result of agricultural expansion and deforestation. Globally, technological innovation and energy mix changes prevented 31 (17–42) Gt CO2e emissions over two centuries. Yet these gains were dwarfed by 81 (64–97) Gt CO2e resulting from economic expansion, with regional drivers diverging sharply: population growth dominated in Latin America and Sub-Saharan Africa, while rising affluence was the main driver of emissions elsewhere. Meeting climate targets now requires the carbon intensity of GDP to decline 3 times faster than the global
Researchers found that between 2002 and 2015, a 3.2% reduction in Brazilian forest cover led to a 5.4% reduction in precipitation levels.
Donald Trump has ordered that swathes of America’s forests be felled for timber, evading rules to protect endangered species while doing so and raising the prospect of chainsaws razing some of the most ecologically important trees in the US. The president, in an executive order, has demanded an expansion in tree cutting across 280m acres (113m hectares) of national forests and other public lands, claiming that “heavy-handed federal policies” have made America reliant on foreign imports of timber.
La destruction de l'Amazonie est un phénomène qui s’étend au-delà de la déforestation mais les neuf pays qui partagent cette ressource naturelle sont engagés à la protéger.
The EU Observatory on deforestation and forest degradation aims to monitor changes in the world’s forest cover and related drivers. Besides providing access to global forest maps and spatial forest and forestry-related information, this Observatory will facilitate access to scientific information on supply chains, linking deforestation, forest degradation and changes in the world’s forest cover to Union demand for commodities and products. Data and information provided on this Observatory play a supporting role but do not assure compliance or imply non-compliance with EU Regulations, other legal frameworks or commitments, or international agreements.
Past governments blamed the growing of coca – the base component of cocaine – for clearcutting, but a recent study shows otherwise
The EU have introduced a new regulation on the import of products linked to deforestation – but will this reduce deforestation globally?
Deforestation coupled with the rampant destruction of natural resources will soon have devastating effects on the future of society as we know it, according to two theoretical physicists who study complex systems and have concluded that greed has put us on a path to irreversible collapse within the next two to four decades.
The destruction of global forests slowed in 2021 but the vital climate goal of ending deforestation by 2030 will still be missed without urgent action, according to an assessment. The area razed in 2021 fell by 6.3% after progress in some countries, notably Indonesia. But almost 7m hectares were lost and the destruction of the most carbon- and biodiversity-rich tropical rainforests fell by only 3%. The CO2 emissions resulting from the lost trees were equivalent to the emissions of the entire European Union plus Japan.
From the seemingly inexorable increase of carbon dioxide in the atmosphere to the rapid growth in green energy
Over the past 60 years, the global forest area has declined by 81.7 million hectares, a loss that contributed to the more than 60% decline in global forest area per capita. This loss threatens the future of biodiversity and impacts the lives of 1.6 billion people worldwide, according to a new study published today by IOP Publishing in the journal Environmental Research Letters.
From the Amazon to the Andes and the snowy depths of Patagonia, extreme weather and climate change are causing mega-drought, extreme rainfall, deforestation and glacier melt across the Latin America and the Caribbean (LAC) region, according to a UN report published on Friday.
Climate analysts are astounded by such a high reading during the rainy season, and is the third monthly record this year
The most widely publicized threat to the Amazonian rainforest is deforestation. Less well understood is that public lands are being converted to private holdings in a land grab we’ve been studying for the past decade... Much of this land is cleared for cattle ranches and soybean farms, threatening biodiversity and the Earth’s climate.
in a new study, we discovered that secondary forests across the Amazon are absorbing just 9.7% of the emissions created by the destruction of old-growth forests in the region. That’s despite these regrowing habitats occupying 28.8% of all deforested land.
At the global level, tropical areas are losing forests at a rate of 10 million hectares per year according to the FAO’s latest report on forest resources, and temperate areas, which are gaining forest area at a rate of 5 million hectares per year. Of the 10 million hectares of forest lost each year, just under two-thirds can be unambiguously attributed to agricultural expansion, with the remaining third being a combination of forest fires, logging and other factors.
