Susan Lozier Appointed to Climate Security Roundtable
By Jess Hunt-Ralston At the direction of Congress, the National Academies of Sciences, Engineering, and Medicine is establishing a Climate Security Roundtable convening experts from academia, the private sector, and civil society to provide support to the Climate Security Advisory Council (CSAC). CSAC is a joint partnership between the U.S. Intelligence Community and the Federal Science Community and seeksContinue reading “Susan Lozier Appointed to Climate Security Roundtable”
2021 brought a wave of extreme weather disasters. Scientists say worse lies ahead.
By Sarah Kaplan and Brady Dennis There are millions of tips out there on “The weather of the past will not be the weather of the future,” says a NOAA scientist. “As long as we are emitting greenhouse gases at a historically unprecedented rate, we should expect this change to continue.” Scores of studies presented this week atContinue reading “2021 brought a wave of extreme weather disasters. Scientists say worse lies ahead.”
The Atlantic’s vital currents could collapse. Scientists are racing to understand the dangers.
By James Temple On a Saturday morning in December of 2020, the RRS Discovery floated in calm waters just east of the Mid-Atlantic Ridge, the massive undersea mountain range that runs from the Arctic nearly to the Antarctic. The team onboard the research vessel, mostly from the UK’s National Oceanography Centre, used an acoustic signaling system to trigger theContinue reading “The Atlantic’s vital currents could collapse. Scientists are racing to understand the dangers.”
How the climate crisis played a role in fueling Hurricane Ida
Louise Boyle Hurricane Ida made landfall last weekend near New Orleans as a Category-4 storm, lashing the region with winds of up to 150mph (240kph), heavy rains and several feet of storm surge on the 16th anniversary of Hurricane Katrina. […] Several factors linked to the climate crisis are helping to fuel more powerful, destructiveContinue reading “How the climate crisis played a role in fueling Hurricane Ida”
A Crucial System of Ocean Currents Is Faltering, Research Suggests
By Heather Murphy The water in the Atlantic is constantly circulating in a complex pattern that influences weather on several continents. And climate scientists have been asking a crucial question: Whether this vast system, which includes the Gulf Stream, is slowing down because of climate change. […] Now, scientists have detected the early warning signsContinue reading “A Crucial System of Ocean Currents Is Faltering, Research Suggests”
OSNAP and Earth’s Heat Pump: The Ocean Conveyor Belt
By Allison Shirreffs The ocean covers more than 70% of the Earth and operates in a state of equilibrium with the atmosphere to regulate climate and CO2 levels. As a result, dynamics that affect the uptake of CO2 across the ocean surface affect global atmospheric temperatures. Lozier, who ( in addition to her duties as dean andContinue reading “OSNAP and Earth’s Heat Pump: The Ocean Conveyor Belt”
In the Atlantic Ocean, Subtle Shifts Hint at Dramatic Dangers
By MOISES VELASQUEZ-MANOFF and JEREMY WHITE The warming atmosphere is causing an arm of the powerful Gulf Stream to weaken, some scientists fear. […] It’s one of the mightiest rivers you will never see, carrying some 30 times more water than all the world’s freshwater rivers combined. In the North Atlantic, one arm of the GulfContinue reading “In the Atlantic Ocean, Subtle Shifts Hint at Dramatic Dangers”

Why is an ocean current critical to world weather losing steam? Scientists search the Arctic for answers.
BY CHERYL KATZ A conveyor belt of ocean water that loops the planet and regulates global temperatures could be heading for a tipping point. THE HIGH ARCTIC, ABOARD THE R.V. KRONPRINS HAAKON Summer sea ice has been shrinking so dramatically here in the Fram Strait, high in the Arctic between Norway and Greenland, that researchersContinue reading “Why is an ocean current critical to world weather losing steam?
