A carbon sink shrinks in the Arctic

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.

Making sense of climate scenarios: Toolkit for decision-makers launched

(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.

Deep learning: A new engine for ecological resource research

(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.

NASA Snow campaign wraps 2020 survey

(NASA/Goddard Space Flight Center) As spring and summer temperatures return to the Northern Hemisphere, winter’s snow is melting, releasing precious fresh water into Earth’s streams, rivers and oceans.

Are hurricanes linked to global warming?

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…

Early Bird uses 10 times less energy to train deep neural networks

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.
