The world wastes roughly a sixth of the food produced each year
A new United Nations report shows where wastes can be reduced, which would decrease hunger and emissions of climate-warming greenhouse gases.

Analyze This: Cows burp less methane after early-life treatment
Calves that receive the 14-week treatment belch less of the greenhouse gas, possibly due to shifts in their gut microbes.

Changing climate now threatens northern lakes year round
Lakes in northern climes are getting warmer, and that’s not good for people, plants or animals.

COVID-19 cut pollution in 2020, warming the atmosphere
Pandemic-related lockdowns briefly warmed the planet. The reason: The cleaner air carried fewer planet-cooling aerosols.

Training AI to be really smart poses risks to climate
As artificial intelligence models grow larger and consume more energy, experts have begun to worry about their impact on Earth’s climate.

Scientists Say: Weather
The state of the atmosphere in a specific place and time is weather. Over a long time, the weather conditions in an area will reveal its climate.

Can wildfires cool the climate?
Severe wildfires are becoming more common. Science is showing that the tiny particles they release into the air can alter Earth’s temperature — sometimes cooling it.

2020 was warmest year on record for Earth’s oceans
2020 continued the trend of record-breaking heat for the world’s oceans. The three previous warmest years on record were 2019, 2017 and 2018.

Let’s learn about snow
Snow is more than just frozen water vapor. Scientists are studying everything from its shape to other planets where snowflakes fall.

Analyze This: 2020 ties with 2016 for hottest year on record
Last year capped the warmest decade on record. It coincided with a growing increase of warming greenhouse gases in Earth’s atmosphere.

A new catalyst turns greenhouse gas into jet fuel
The catalyst is an improvement over its predecessors. Made of cheap materials like iron, it produces jet fuel in a single step.

Surprising long-haul dust and tar are melting high glaciers
Dust and tar blown onto high mountains, like the Himalayas, boost the melting of snow and ice far more than scientists had realized. Here’s why.
