As Arctic ice melts, massive amounts of freshwater flow into the ocean. The seawater becomes diluted and less saline, a development that reduces its density and causes it to sink more…Continue readingLong-term costs of global warming: Weaker ocean circulation could cost trillions

A collapse of the Atlantic Meridional Overturning Circulation (AMOC) would have disastrous consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South…Continue readingTotal collapse of vital Atlantic currents unlikely this century, study finds
Reykjavik, October 2024: Science increasingly confirms that the Arctic region is a “ground zero” for tipping point risks and climate regulation across the planet. In this region, the Greenland Ice Sheet,…Continue readingOpen Letter by Climate Scientists to the Nordic Council of Ministers
The pace of global heating has been significantly underestimated, according to renowned climate scientist Prof James Hansen, who said the international 2˚C limit is “dead”. A new analysis by Hansen and…Continue readingClimate change limit of +2˚C is ‘dead’, says renowned climate scientist
“Our paper says that the Atlantic overturning has not declined yet,” said Foukal, who conducted the research while at Woods Hole Oceanographic Institution (WHOI). “That doesn’t say anything about its future,…Continue readingCritical ocean current has not declined in the last 60 years, AMOC study finds
By David Spratt at Climate Code Red If an unexpected leap in the global average temperature in 2023 was described by one scientist as “gobsmackingly bananas”, are there even words to…Continue readingA(nother) year of scientific shock and awe
The dangers of a collapse of the main Atlantic Ocean circulation, known as AMOC, have been “greatly underestimated” and would have devastating and irreversible impacts, according to an open letter released…Continue reading‘We don’t know where the tipping point is’: climate expert on potential collapse of Atlantic circulation
A world where global mean surface temperature has increased 3°C will be characterized by widespread and intense heat stress, extreme weather events, ruptured and unproductive marine and terrestrial ecosystems, broken food…Continue readingEarth at risk: An urgent call to end the age of destruction and forge a just & sustainable future
Ocean currents are driven by winds, tides and water density differences. In the Atlantic Ocean circulation, the relatively warm and salty surface water near the equator flows toward Greenland. During its…Continue readingOnce melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades
AMOC, which encompasses part of the Gulf Stream and other powerful currents, is a marine conveyer belt that carries heat, carbon and nutrients from the tropics towards the Arctic Circle, where…Continue readingAtlantic Ocean circulation nearing ‘devastating’ tipping point
Most people expect that if a system, like someone’s body, an ecosystem, or part of the climate system, becomes stressed, it’ll respond fairly predictably—double the pressure, double the impact, and so…Continue readingClimate tipping points are nearer than you think. Our new report warns of catastrophic risk.
By Christoper Ketcham The Intergovernmental Panel on Climate Change has assumed Nordhaus is to be trusted. The integrated assessment models used at the IPCC are based on Nordhausian visions of adaptation…Continue readingWhen Idiot Savants Do Climate Economics
In late July, a study published in Nature Communications warned that a critical ocean system that brings warm water up the North Atlantic, also known as the Atlantic Meridional Overturning Circulation…Continue readingAtlantic collapse: Q&A with scientists behind controversial study predicting a colder Europe
Using advanced statistical tools and ocean temperature data from the last 150 years, the researchers calculated that the ocean current, known as the Thermohaline Circulation or the Atlantic Meridional Overturning Circulation…Continue readingGloomy climate calculation: Scientists predict a collapse of the Atlantic ocean current to happen mid-century
Much of the ice lost in 2022 had been present since 2000, when high-quality records began. If this trend persists, the consequences for the climate and for Southern Ocean ecosystems could…Continue readingFractured foundations: How Antarctica’s ‘landfast’ ice is dwindling and why that’s bad news
We found melting of Antarctic ice is disrupting the formation of Antarctic bottom water. The meltwater makes Antarctic surface waters fresher, less dense, and therefore less likely to sink. This puts…Continue readingAntarctic alarm bells: Observations reveal deep ocean currents are slowing earlier than predicted
The groundbreaking modeling study published by Australian and American researchers at the end of March for the first time includes a detailed assessment of the likely impact of melting ice, revealing…Continue readingNew Research Sparks Concerns That Ocean Circulation Will Collapse
The Atlantic meridional overturning circulation (AMOC), a system of ocean currents that carry warm water from the tropics into the North Atlantic, and transport cold water from the northern to the…Continue readingScientists discover mechanism that can cause collapse of great Atlantic circulation system
