How scientists wrestle with grief over climate change

With climate change altering our world at an increasing pace, scientists who monitor and study nature are frustrated and grieving.

Climate

Economic costs of rising seas will be steeper than we thought, unless we prepare

A study estimates 4 percent in annual global GDP losses by 2100 due to sea level rise, unless people curb emissions and prepare for flood risks.

Climate

Climate change is slowly drying up the Colorado River

Annual water flow in the Colorado River decreased by over 11 percent due to warming in the 20th century, a new study estimates.

Climate

Fossil fuel use may emit 40 percent more methane than we thought

Ice cores suggest natural seeps release less methane than was estimated, meaning industry produces nearly all of today’s geologic methane emissions.

Tech

The U.S. power grid desperately needs upgrades to handle climate change

The climate is changing faster than the U.S. power grid is adapting. Smarter grids and smaller grids could help.

Ecosystems

Will Australia’s forests bounce back after devastating fires?

Intense bushfires that have blazed down Australia’s eastern coast could have long-lasting effects on the continent’s unique plants and animals.

Oceans

Noise pollution from ships may scare Arctic cod from feeding grounds

Melting Arctic sea ice is opening up northern waters to increased shipping, and the vessel noise is taking a toll on Arctic cod.

Climate

Climate change may be speeding up ocean circulation

Circulation in the top 2,000 meters of the world’s oceans has increased as a result of faster winds around the globe, a study suggests.

A new roadmap shows how the U.S. could be carbon-neutral by 2050

A new report charts a roadmap for the U.S. to have zero carbon footprint by 2050, but only with heavy and immediate investment in carbon removal technologies.

Tiny meteorites suggest ancient Earth had a carbon dioxide–rich atmosphere

Simulations of reactions between 2.7-billion-year-old micrometeorites and atmospheric gases hint Archean Earth’s atmosphere had high levels of CO2.

A 2.2-billion-year-old crater is Earth’s oldest recorded meteorite impact

The newly dated Yarrabubba crater in Western Australia extends Earth’s impact record by more than 200 million years.
