Research has studied the effects of climate risk on financial markets, but few studies have addressed the effect of environmental policy on those markets. A new study examined whether federal policy aimed at mitigating local air…

Even a modest sea level rise, triggered by increasing global temperatures, would place 100 airports below mean sea level by 2100, a new study has found Even a modest sea level rise, triggered by increasing global temperatures, would place…

Uncertainty about annual methane emissions from abandoned wells in US and Canada highlights need for better measurementsCredit: Mary Kang A recent McGill study published in Environmental Science and Technology finds that annual…

When Iceland's Laki volcano erupted in 1783, its effects rippled around the world. UArizona researchers have analyzed Alaskan tree rings to understand how climate responded in northwestern North America. The work will aid in fine-tuning…

New findings on the Atlantic El Niño El Niño or correctly El Niño - Southern Oscillation (ENSO) is the strongest natural climate fluctuation on time scales of a few years. Through ocean and atmosphere interactions, El Niño (Spanish for The…

Over the last half-century, the probability of heat extreme events has changed by orders of magnitude in almost every region of the world, with occurrences that are now up to a hundred times more in respect to a century ago. Of…

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago - and found…

Researchers model the regional impacts of specific anthropogenic activities and their influence on extreme fire weather risk When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, Danielle Touma, at the…
