A study by mathematicians has used new techniques to address the long-running debate over whether battle deaths have been declining globally since the end of the Second World War.
Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean’s ability to absorb carbon dioxide from the atmosphere into the deep ocean and store it there.
Study reveals drainage, deforestation of the region’s peatlands, which leads to fires, greenhouse emissions, land subsidence.
(Potsdam Institute for Climate Impact Research (PIK)) To make climate scenarios work for decision-makers, an international team of researchers developed a comprehensive interactive online platform. It is the first of its kind to provide the tools to use those scenarios — from climate impacts to mitigation and energy options — to a broader public beyond science.
(Science China Press) Deep learning is driven by big data, which brings new opportunities for target classification, detection, semantic segmentation, instance segmentation, and regression in ecological resource research. However, there are still great challenges in the standardization and sharing of data, the universality and interpretability of algorithms, and the enrichment and intelligence of applications. A recent study clarified the aforementioned frontier issues, which was published in the ‘Science China Terrae’ journal.
Global warming is adding more moisture to the atmosphere, providing more fuel for big storms like hurricanes. But tropical cyclones are extremely complicated. How much can we really link them to human-induced climate change? It depends on the link. We…
Engineers have found a way to train deep neural networks for a fraction of the energy required today. Their Early Bird method finds key network connectivity patterns early in training, reducing the computations and carbon footprint for training deep learning.
Arctic sea ice helps keep Earth cool, as its bright surface reflects the Sun’s energy back into space.
