Flooded Future: New elevation maps triple estimates of global risk from sea-level rise and coastal flooding – “By 2100, land now home to 200 million people could sit permanently below the high tide line”

29 October 2019 (Climate Central) – Sea level rise is one of the best known of climate change’s many dangers. As humanity pollutes the atmosphere with greenhouse gases, the planet warms. And as it does so, ice sheets and glaciers melt and warming sea water expands, increasing the volume of the world’s oceans. The consequences […]

If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 meters in coming centuries

By Georgia Rose Grant and Timothy Naish 2 October 2019 (The Conversation) – We know that our planet has experienced warmer periods in the past, during the Pliocene geological epoch around three million years ago. Our research, published today, shows that up to one third of Antarctica’s ice sheet melted during this period, causing sea levels to rise […]

Shocked scientists find 400 km of dead and damaged mangroves in Australia’s Gulf of Carpentaria – “We are getting these compounding effects that we just didn’t expect”

By Graham Readfearn 3 October 2019 (The Guardian) – A cascade of impacts including rising sea levels, heatwaves and back-to-back tropical cyclones has created 400 kilometers [249 miles] of dead and badly damaged mangroves in the Gulf of Carpentaria, a scientific monitoring trip has discovered. Prof Norman Duke, of James Cook University, spent 10 days […]

Landmark “United in Science” report brings together world’s leading climate science organizations

NEW YORK, 22 September 2019 (WMO) – The world’s leading climate science organizations have joined forces to produce a landmark new report  [pdf] for the United Nations Climate Action Summit, underlining the glaring – and growing – gap between agreed targets to tackle global warming and the actual reality. The report, United in Science, includes details on the […]

“What death smells like”: Dorian’s toll expected to soar in Bahamas – Official warns people to prepare for the “unimaginable” – “Literally hundreds, up to thousands, of people are still missing”

By Nick Brown 6 September 2019 MARSH HARBOUR, Bahamas (Reuters) – The smell of death hangs over parts of Great Abaco Island in the northern Bahamas, where relief workers on Friday sifted through the debris of shattered homes and buildings in a search expected to dramatically drive up the death toll from Hurricane Dorian. Dorian, […]

Hurricane Dorian leaves neighborhoods flattened and homes shredded in the Bahamas – “We are in the midst of one of the greatest national crises in our country’s history”

4 September 2019 (CBS News) – As Hurricane Dorian accelerates up the Florida coast, the magnitude of the storm’s destruction in the Bahamas is coming into view. Parts of the island nation are in ruins. Much of Grand Bahama Island is underwater. Two more deaths were confirmed overnight, bringing the official total now to seven. The country’s prime minister […]

Indonesia announces site of capital city to replace sinking Jakarta – Choice of Borneo for £27 billion project raises fears of forest destruction and pollution

By Jonathan Watts 26 August 2019 (The Guardian) – Indonesia has announced plans to move its capital from the climate-threatened megalopolis of Jakarta to the sparsely populated island of Borneo, which is home to some of the world’s greatest tropical rainforests. President Joko Widodo said the move was necessary because the burden on Jakarta was […]

Large rivers of melting water form on an ice sheet in western Greenland on 1 August 2019 and drain into moulin holes that empty into the ocean from underneath the ice. The heat wave that smashed high temperature records in five European countries a passed over Greenland, accelerating the melting of the island's ice sheet and causing massive ice loss in the Arctic.

Bizarre happenings in the Arctic: Lightning, tropical moisture, and more

By Bob Henson 14 August 2019 (Weather Underground) – You’ll have to forgive the Arctic. It’s had a rough summer. Sea ice is running neck and neck with 2012 for the lowest values on record for this time of year. Wildfires are ringing the Arctic, pouring more carbon dioxide into the air than in any comparable period in 17 […]

First evidence of human-caused climate change melting the West Antarctic Ice Sheet

12 August 2019 (British Antarctic Survey) – A new study published this week reveals the first evidence of a direct link between human-induced global warming and melting of the West Antarctic Ice Sheet. UK-US researchers say that curbing greenhouse gas emissions now could reduce the future sea-level contribution from this region. Ice loss in West […]
