A new modeling approach can help researchers, policymakers, and the public better understand how policy decisions will influence human migration as sea levels rise around the globe, a paper published today in Nature Climate Change suggests.
The fabled use of canaries in coal mines as an early warning of carbon monoxide stemmed from the birds’ extreme sensitivity to toxic conditions compared to humans.
"In independent studies, two Princeton University research teams recently identified surprisingly large sources of methane, a powerful greenhouse gas, being leaked into the atmosphere. Pound for pound, methane causes a far greater warming effect in the atmosphere than does carbon dioxide — 86-fold more heating over 20 years, and 35-fold more...
C-PREE postdoc, Stuart Riddick, worked with Prof. Denise Mauzerall (C-PREE), Prof. Michael Celia (PEI), and an international team of researchers to measure powerful greenhouse gas emissions from oil and gas rigs in the North Sea, discovering that current counts underestimate the amount of methane being released into the atmosphere.
"By 2050, the world must feed many more people, more nutritiously, and ensure that agriculture contributes to poverty reduction through inclusive economic and social development, all while reducing greenhouse gas (GHG) emissions, loss of habitat, freshwater depletion and pollution, and other environmental impacts of farming.
"A verdant, nearly roadless place, the Western Amazon in South America may be the most biologically diverse place in the world. There, many people live in near isolation, with goods coming in either by river or air. Turning to crops for profit or sustenance, farmers operate small family plots to make a living.
"Princeton researchers have provided the first estimation of the potential damage from back-to-back, or compound, heat waves, which the authors found will increase as global warming continues. But government warning systems and health care outreach do not currently calculate the risks of sequential heat waves.
C-PREE Research Scholar, Tim Searchinger, and his colleague, Richard Waite, discuss the promise of plant-based burgers to decrease the impact that cattle and other grazing animals have on the environment.
