Snow chaos in Europe caused by melting sea-ice in the Arctic
The April snow falling on fruit blossoms in Europe these days may be directly connected to the loss of the sea ice in the Barents Sea in the Arctic. That was definitely the case in 2018 when the sudden cold spell known as 'Beast from the East' descended on the mid-latitudes of the continent, a new study shows.

They are diligently stoking thousands of bonfires on the ground close to their crops, but the French winemakers are fighting a losing battle. An above-average warm spell at the end of March has been followed by days of extreme frost, destroying the vines with losses amounting to 90 percent above average. The image of the struggle may well be the most depressingly beautiful illustration of the complexities and unpredictability of global climate warming. It is also an agricultural disaster from Bordeaux to Champagne.

It is the loss of the Arctic sea-ice due to climate warming that has, somewhat paradoxically, been implicated with severe cold and snowy mid-latitude winters.

This Glacier in Alaska Is Moving 100 Times Faster Than Normal
The Muldrow Glacier in Alaska is moving 100 times its normal rate.

In what’s known as a glacial surge, the 39-mile-long river of ice has been moving as much as 90 feet a day over the past few months. Surges generally last only a few months and are often detected only after they’ve ended. But the Muldrow is within Denali National Park and Preserve, and planes regularly fly over it, making Muldrow ripe for observation.

Because of surge’s relative rarity, scientists haven’t been able to study surges enough to have a complete understanding of why they happen, or to gauge how climate change, which is rapidly melting glaciers in Alaska and elsewhere, may be affecting them.

Climate change is making Indian monsoon seasons more chaotic
If global warming continues unchecked, summer monsoon rainfall in India will become stronger and more erratic. This is the central finding of an analysis by a team of researchers that compared more than 30 state-of-the-art climate models from all around the world. The study predicts more extremely wet years in the future - with potentially grave consequences for more than one billion people's well-being, economy, food systems and agriculture.

A look into the past underlines that human behavior is behind the intensification of rainfall. Starting in the 1950s, human-made forcings have begun to overtake slow natural changes occurring over many millennia. At first, high sun-light blocking aerosol loadings led to subdued warming and thus a decline in rainfall, but since then, from 1980 onwards, greenhouse gas-induced warming has become the deciding driver for stronger and more erratic Monsoon seasons.

Climate change is making it harder to get a good cup of coffee
Ethiopia may produce less specialty coffee and more rather bland tasting varieties in the future. This is the result of a new study by an international team of researchers that looked at the peculiar effects climate change has on Africa's largest coffee producing nation. Their results are relevant both for the country's millions of smallholder farmers, who earn more on specialty coffee than on ordinary coffee, as well as for baristas and coffee aficionados around the world.

To improve climate models, an international team turns to archaeological data
To improve climate models, an international team turned to archaeological data. The resulting classification from the project, called LandCover6k, offers a tool the researchers hope might generate better predictions about the planet's future and fill in gaps about its past.

Climate modeling is future facing, its general intent to hypothesize what our planet might look like at some later date. Because the Earth's vegetation influences climate, climate models frequently include vegetation reconstructions and are often validated by comparisons to the past. Yet such models tend to get oversimplified, glossing over or omitting how people affected the land and its cover.

The absence of such data led to LandCover6k, a project now in its sixth year that includes more than 200 archaeologists, historians, geographers, paleoecologists, and climate modelers around the world.

Climate change, periodic modification of Earth’s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.

Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
