Did the drop in COVID-related emissions affect the climate?

As social and economic activity ground to a halt around the world in 2020 in the face of the COVID-19 pandemic, emissions of greenhouse gases and aerosols dropped. In the United States, where lockdowns that began in March ...

Climate action potential in waste incineration plants

Over the coming decades, our economy and society will need to dramatically reduce greenhouse gas emissions as called for in the Paris Agreement. But even a future low-carbon economy will emit some greenhouse gases, such as ...

The surprising power of chicken manure

Each year, American farmers raise billions of chickens, more than enough for a "chicken for every pot," as Herbert Hoover's campaign once promised.

Climate change: Amazon may be turning from friend to foe

The Brazilian Amazon released nearly 20 percent more carbon dioxide into the atmosphere over the last decade than it absorbed, according to a stunning report that shows humanity can no longer depend on the world's largest ...

Northern forest fires could accelerate climate change

New research indicates that the computer-based models currently used to simulate how Earth's climate will change in the future underestimate the impact that forest fires and drying climate are having on the world's northernmost ...

EU climate law a step in the right direction, researchers say

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".
