Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth’s atmosphere are not equal to the climate changes from deliberate CO2 removals—and assuming such a balance could lead to different climate outcomes that may skew climate targets, according to new Simon Fraser University-led research.

Earth bears many signs of human influence, from warming that exceeds pre-industrial temperatures to a rising sea.

Some 56 million years ago, just after the Paleocene epoch gave way to the Eocene, the world suddenly warmed.

May was arguably the worst month ever for big oil — and the best for its opponents — as courts and corporate shareholders sided with environmental activists to humble the biggest of the fossil-fuel giants, culminating in “Black Wednesday.”

Russia is the world’s largest forest country. Being home to more than a fifth of forests globally, the country’s forests and forestry have enormous potential to contribute to making a global impact in terms of climate mitigation.

Measuring ethane in the atmosphere shows that the amounts of methane going into the atmosphere from oil and gas wells and contributing to greenhouse warming is higher than suggested by the U.S. Environmental Protection Agency, according to an international team of scientists who spent three years flying over three areas of the U.S. during all four seasons.

While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as “blue-green algae” or cyanobacteria, that forms harmful floating blooms.

A first-of-its-kind large-scale study of vegetation growth in the Northern Hemisphere over the past 30 years has found that vegetation is becoming increasingly water-limited as global temperatures increase.

Temperature significantly increased and snowfall decreased in the iconic Greater Yellowstone Area since 1950 because of climate change, and these trends will likely continue through the rest of the century, according to a climate report published today.

There is a race going on high in the atmosphere above the Arctic, and the ozone layer that protects Earth from damaging ultraviolet (UV) radiation will lose the race if greenhouse gas emissions aren’t reduced quickly enough.
