Could residential heat pumps be part of the climate solution?

Deploying residential heat pumps more widely across the United States has the potential to help reduce carbon pollution while also saving homeowners money, according to a new study by a University of Michigan researcher and ...

Video: Counting carbon

The Paris Agreement adopted a target for global warming not to exceed 1.5°C. This sets a limit on the additional carbon we can add to the atmosphere—the carbon budget. Only around 17% of the carbon budget is now left. ...

Key UN climate science talks open amid floods, fires

Nearly 200 nations start online negotiations Monday to validate a UN science report that will anchor autumn summits charged with preventing climate catastrophe on a planetary scale.

Reducing industrial carbon emissions

A critical challenge in meeting the Paris Agreement's long-term goal of keeping global warming well below 2 degrees Celsius is to vastly reduce carbon dioxide (CO2) and other greenhouse gas emissions generated by the most ...

Experts: Europe floods show need to curb emissions, adapt

Just as the European Union was announcing plans to spend billions of euros to contain climate change, massive clouds gathered over Germany and nearby nations to unleash an unprecedented storm that left death and destruction ...

The shifting dynamics of temperate marine ecosystems

At Shikine Island, Japan, kelp forests and abalone fisheries were once common, but over the last twenty years they have disappeared. Now, researchers from Japan have discovered that these temperate coastal marine ecosystems ...

Greenhouse gas

Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In our solar system, the atmospheres of Venus, Mars and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33°C (59°F) colder than at present.

Human activities since the start of the industrial era around 1750 have increased the levels of greenhouse gases in the atmosphere. The 2007 assessment report compiled by the IPCC observed that "changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system", and concluded that "increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century".
