Harbin Ice Festival 2019: Rising temperatures in China cause Harbin ice sculptures to melt. Ice and snow sculptures carved by nearly 10,000 artists in the city of Harbin have melted during a sudden warm spell, forcing the earliest closure of the main venue at China's biggest winter festival.

Harbin Ice Festival 2019: Rising temperatures in China cause Harbin ice sculptures to melt

Daytime temperatures have poked above freezing in northern China's warmest week this winter, prompting the closure of the Harbin Ice and Snow World after Sunday, more than 10 days ahead of schedule. "Of course, we do have a sense of crisis," a park official said, adding that it was closed for safety reasons because the sculptures had started to melt. The winter park in Harbin, a northeastern city known for its bitterly cold weather, had attracted more than one million visitors since it opened on December 23. Some visitors who made bookings to marvel at mini ice replicas of the Colosseum and the Milan Cathedral were disappointed by the early closure.

Climate and economic risks 'threaten 2008-style systemic collapse' The gathering storm of human-caused threats to climate, nature and economy pose a danger of systemic collapse comparable to the 2008 financial crisis, according to a new report that calls for urgent and radical reform to protect political and social systems.

Climate and economic risks 'threaten 2008-style systemic collapse'

The study says the combination of global warming, soil infertility, pollinator loss, chemical leaching and ocean acidification is creating a “new domain of risk”, which is hugely underestimated by policymakers even though it may pose the greatest threat in human history. “A new, highly complex and destabilised ‘domain of risk’ is emerging – which includes the risk of the collapse of key social and economic systems, at local and potentially even global levels,” warns the paper from the Institute for Public Policy Research.

“This new risk domain affects virtually all areas of policy and politics, and it is doubtful that societies around the world are adequately prepared to manage this risk.”

Shortly after Hurricane Helene formed off the coast of West Africa on September 7, it did something unusual.

Rogue hurricanes that head northwards may be new normal

Instead of following most hurricanes westward across the Atlantic, Helene turned north towards the UK and Ireland. Now downgraded to an “ex-hurricane”, Storm Helene is nonetheless expected to bring strong winds across much of England and Wales when it hits on September 17. Something similar happened in October 2017 when ex-Hurricane Ophelia turned north and hit the British Isles, causing three deaths and more than 200,000 homes to lose power.

At the time, Ophelia seemed like a very unusual storm due to the direct course it took across the Atlantic. Container ship crosses Arctic route for first time in history due to melting sea ice. Warming oceans are changing the world's rainfall. Global warming means truly global warming.

Warming oceans are changing the world's rainfall

The atmosphere, the oceans, and the ground are all warming. As a result, ice is melting, seas are rising, storms are getting more severe, and droughts are getting worse. The 2015 landslide and tsunami in Taan Fiord, Alaska. Climate change is driving worldwide glacial retreat and thinning1 that can expose unstable hillslopes.

The 2015 landslide and tsunami in Taan Fiord, Alaska

The removal of glacial ice supporting steep slopes combined with the thawing of permafrost in alpine regions2 increases the likelihood of landslides3,4,5,6. Glaciers undercut slopes, priming them for failure by deepening and widening valley bottoms, and by producing steeper valley walls7. Additionally, ice loading produces stress fractures in the underlying bedrock, further preparing slopes for failure8. - The Washington Post.

Summer weather is getting 'stuck' due to Arctic warming. Summer weather patterns are increasingly likely to stall in Europe, North America and parts of Asia, according to a new climate study that explains why Arctic warming is making heatwaves elsewhere more persistent and dangerous.

Summer weather is getting 'stuck' due to Arctic warming

Rising temperatures in the Arctic have slowed the circulation of the jet stream and other giant planetary winds, says the paper, which means high and low pressure fronts are getting stuck and weather is less able to moderate itself. The authors of the research, published in Nature Communications on Monday, warn this could lead to “very extreme extremes”, which occur when abnormally high temperatures linger for an unusually prolonged period, turning sunny days into heat waves, tinder-dry conditions into wildfires, and rains into floods.

British farmers in turmoil as delayed spring plays havoc with growing season

This spring, they are not expecting to harvest their open-field crop until the last week of April – a week later than the official start of the season, St George’s Day, 23 April. Welcome to just one of the consequences of Britain’s disastrously delayed spring. “We have had a very challenging time,” said Guy Smith, vice president of the National Farmers’ Union (NFU). “March breezed in with the ‘beast from the east’ and went out with the worst bank holiday on record.”

For asparagus-lovers there is at least an upside. Climate change dials down Atlantic Ocean heating system. Image copyright WHOI A significant shift in the system of ocean currents that helps keep parts of Europe warm could send temperatures in the UK lower, scientists have found. They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years - and has changed significantly in the past 150. Floods and erosion are ruining Britain’s most significant sites. Climate change is already wrecking some of Britain’s most significant sites, from Wordsworth’s gardens in Cumbria to the white cliffs on England’s south coast, according to a new report. Floods and erosion are damaging historic places, while warmer temperatures are seeing salmon vanishing from famous rivers and birds no longer visiting important wetlands. The report was produced by climate experts at Leeds University and the Climate Coalition, a group of 130 organisations including the RSPB, National Trust, WWF and the Women’s Institute.

“Climate change often seems like a distant existential threat [but] this report shows it is already impacting upon some of our most treasured and special places around the UK,” said Prof Piers Forster of Leeds University.
