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.…Continue readingOnce melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades
Tag: amoc
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…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,…Continue readingClimate tipping points are nearer than you think. Our new report warns of catastrophic risk.
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 to…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…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…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…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.…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…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…Continue readingScientists discover mechanism that can cause collapse of great Atlantic circulation system
