At the moment, fires burning across Indonesia since July have destroyed over burned 8,578 square kilometers (3,304 square miles and around the size of Puerto Rico) as of the end of September, blanketing the islands in thick toxic smoke which has turned the sky a violent red.
New research indicates that parts of the Amazon and other tropical forests are now emitting more CO2 than they absorb. Some scientists are concerned this development, which is not yet incorporated into climate models, could put the temperature goals set by the Paris Agreement out of reach.
Preventing global warming from becoming “dangerous” may have just got significantly harder after new research suggested climate scientists have been using the wrong baseline temperature.
Of the many threats from climate change, sea-level rise will most certainly be among the most impactful, making hundreds of thousands of square miles of coastline uninhabitable and potentially displacing over 100 million people worldwide by the end of the century. This threat is a top concern for national security experts because forced migration poses significant risks to international security and stability.
New research, published in Nature Climate Change and available on Global Forest Watch, found that the world’s forests sequestered about twice as much carbon dioxide as they emitted between 2001 and 2019. In other words, forests provide a “carbon sink” that absorbs a net 7.6 billion metric tonnes of CO2 per year, 1.5 times more carbon than the United States emits annually.
In this revelatory work, Jeffrey Moussaieff Masson shows how food affects our moral selves, our health, and the environment. It raises questions to make us conscious of the decisions behind every bite we take: What effect does eating animals have on our land, waters, even global warming?
We estimate the CDR potential of returning UK land currently used for animal agriculture to
forest cover in two scenarios. Our first scenario maximises CDR by restoring land currently under pasture and cropland used to produce farmed animal feed to forest.
Livestock uses huge amounts of land, both for grazing and for growing feed. Indeed, one estimate is that if we all went vegan, we could reduce the land used by agriculture by 75%. It is inherently inefficient to grow grain and soya to feed to animals and then eat the animals, rather than eating the grain and soya directly.
We now know that greenhouse gases are rising faster than at any time since the demise of dinosaurs, and possibly even earlier. According to research published in Nature Geoscience this week, carbon dioxide (CO₂) is being added to the atmosphere at least ten times faster than during a major warming event about 50 million years ago.
Numbers of oceanic sharks and rays have declined at what researchers describe as an “alarming” 71 per cent over almost half a century, leading to what researchers say is an unprecedented increase in risk of extinction.
Conservationists have been warning for years about the unsustainable killing of the apex predators, based on regional reports and data on individual species, but a paper published today is the first to offer an authoritative global overview
