Storing carbon dioxide (CO2) deep below the seabed is one way to counteract the increasing concentration of CO2 in the atmosphere. But what happens if such storage sites begin to leak and CO2 escapes through the seafloor? Answers to this question have now been provided by a study dealing with the effects of CO2 emissions on the inhabitants of sandy seabed areas.

Renewable energy solutions are often hindered by the inconsistencies of power produced by wind, water and sunlight and the continuously fluctuating demand for energy. New research by Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, and colleagues at the University of California, Berkeley, and Aalborg University in Denmark finds several solutions to making clean, renewable energy reliable enough to power at least 139 countries.

Depending on your location, January brought a warmer or colder start to the year. Data show that much-above-average temperatures in the West offset below-average conditions in the East and made for a slightly warmer-than-average January for the nation as a whole.

Pine trees become temporarily sterile when exposed to ultraviolet radiation as intense as some scientists believe the Earth experienced 252 million years ago during the planet’s largest mass extinction, lending support to the theory that ozone depletion contributed to the crisis.

Ultrafine aerosol particles found in polluted urban air can contribute to more intense storms in the Amazon rainforest, with potential knock-on effects for weather and climate patterns in the region and beyond, researchers have warned.

Vertical wind shear was still affecting Tropical Cyclone Cebile when NASA's Terra satellite passed over the Southern Pacific Ocean on Feb. 6. Cebile is undergoing a transition into a subtropical cyclone.

Hydrogen is the most abundant element in the universe. And as the race to find energy sources to replace our dwindling fossil fuel supplies continues, hydrogen is likely to play a crucial role.

Hundreds of methane flares observed offshore Western Svalbard in the Arctic are caused by a process that started at the end of the last ice age, according to the study. The methane release happens because the gas is freed from melting hydrates – an icy substance found below the ocean floor, containing methane in a cage of frozen water.

Global ozone has been declining since the 1970s owing to certain man-made chemicals. Since these were banned, parts of the layer have been recovering, particularly at the poles.

The 2017 hurricane season is one for the record books. A seemingly relentless line of storms tore, one after another, across the Caribbean and into the Gulf Coast. Seventeen of them were strong enough to be named, with the strongest – Hurricanes Harvey, Irma, Maria, and Nate – conspiring to inflict an estimated 350 deaths and some $400 billion in property damage.
