Climate crisis: World's forests losing ability to absorb carbon, finds study

Hindustan Times  

A landmark study has found, the world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans. The scientists say these global variations could make it harder to predict the global impact of schemes to absorb carbon. Dr McGuire said: "We found that large regions of the world are vulnerable to sudden and dramatic changes to their landscape because the ability of their ecosystems to absorb carbon starts to destabilise. The scientists say these global variations could make it harder to predict the global impact of schemes to absorb carbon, such as planting trees, in helping the world reach carbon net zero.

Warm extremes undermine ecosystem carbon sequestration: study

China Daily  

URUMQI -- Researchers have discovered that Earth's terrestrial carbon sequestration capacity has faced challenges during warm extreme occurrences -- periods of unusually high temperatures driven by climate change -- over the past 40 years, according to a recent research article published in the journal Nature Ecology & Evolution. The net ecosystem exchange, determining the terrestrial carbon sequestration capacity, is strongly …

Post-glacial ecosystems could help slow down climate change: Study

The Hindu  

The retreat of glaciers may be one of the most evident signs of climate change, but it will leave behind new ecosystems that could help mitigate climate change, says a global study titled ‘The Development of Terrestrial Ecosystems Emerging After Glacier Retreat’. The study, published in multidisciplinary science journal Nature, suggests that deglaciation may accelerate climate change by reducing surface …

Study: Big gap in carbon removal effort key to climate goals

Associated Press  

BERLIN — Researchers say efforts to remove carbon dioxide from the atmosphere aren’t being scaled up fast enough and can’t be relied on to meet crucial climate goals. Developing countries argue that their contribution to global carbon removal — mostly in the form of forests and land management — are equally important and deserve greater recognition. The study concludes that …

India seeks common carbon budget to combat emissions

Hindustan Times  

Measures to reduce carbon emissions must be guided by science and the principle that the carbon budget is a global commons, India proposed at the UN Climate Conference during a closed-door meeting on Tuesday, people aware of the matter said. The stand signals India pressing ahead on a contentious issue – that there be a distinction between the obligations of …

On my last field visit to the Aravallis, a curiously bright creature ran over my toes. Just this year, fires have seared the forests of the Sariska tiger reserve, cyclone Asani has brushed past east India, and decadal heat records have been shattered. It is interesting, then, that India is attempting to change its suite of environmental laws, including the …

The world’s biggest such complex will capture 4,000 tonnes of greenhouse gas per year in boxes the size of shipping containers.

Climate change, deforestation turned Amazon forest into major CO2 emitter

Firstpost  

If Amazonia — with 450 billion tonnes of CO2 locked in its trees and soil — were to become a consistent source, tackling the crisis would be more challenging. Climate change and deforestation have flipped a large swathe of the Amazon basin from absorbing to emitting planet-warming CO2, a transformation that could turn humanity’s greatest natural ally in the fight …

African Rainforests Useful in Slow Climate Change Despite Record Heat, Drought: Study

News 18  

Africa’s tropical forests appear more resilient as carbon sinks than Amazonian rainforests – mopping up planet-warming carbon dioxide even when sizzling El Nino heat halted absorption in other parts of the world, researchers said on Monday. The new study found that trees in the African forests continued to remove carbon dioxide from the atmosphere, despite experiencing drought and a warming …

Brazil's Amazon forest released more CO2 than it absorbed over the last decade: Study

Firstpost  

If the region were to become a source of CO2 rather than a “sink”, tackling the climate crisis will be that much harder. The Brazilian Amazon released nearly 20 percent more carbon dioxide into the atmosphere over the last decade than it absorbed, according to a stunning report that shows humanity can no longer depend on the world’s largest tropical …

Carbon might boost forest, grassland growth but absorption capacity of soil decreases

The new study adds to growing evidence that the terrestrial carbon sink is weaker than once thought. “Either soil or plants, but not both, will absorb more CO2 as carbon levels rise,” lead author Cesar Terrer, a researcher at Lawrence Livermore National Laboratory in California, told AFP. But researchers said that when elevated carbon dioxide levels boost forest and grassland …

Two-thirds of tropical rainforests destroyed or degraded globally, NGO says

India Today  

Humans have degraded or destroyed roughly two-thirds of the world’s original tropical rainforest cover, new data reveals raising alarm that a key natural buffer against climate change is quickly vanishing. Logging and land conversion, mainly for agriculture, have wiped out 34 per cent of the world’s original old-growth tropical rainforests, and degraded another 30%, leaving them more vulnerable to fire …

Stronger, frequent forest fires effecting tree's carbon sink capabilities: Study

Firstpost  

Stronger and more frequent wildfires are reducing forests’ ability to store carbon in a trend that will likely not be offset by planting new trees, a study said Thursday. Because not all areas are suitable for mass reforestation, and because the long-term impact of fires take decades to gauge, the team said simply replanting the trees would likely fail to …

Trees that grow quickly die younger, risking a release of carbon dioxide that challenges forecasts that forests will continue to be a “sink” for planet-warming emissions, scientists said Tuesday. But in the study, led by England’s Leeds University and published in the journal Nature Communications, they warned that this faster growth was also linked to trees dying younger — suggesting …
