Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century.
- Climate
Climate may have sent drift of the North Pole toward Greenland
This mid-1990s shift in the pole’s movement was driven by glacial melt. And that was triggered in part by climate change, a new study reports.
- Earth
Here’s how lightning may help clean the air
Airplane observations show that storm clouds can generate huge quantities of air-cleansing chemicals known as oxidants.
- Climate
Surfing the winds would make future jet travel greener
Simple route changes could drastically cut fuel use and greenhouse-gas emissions, a new study finds.
- Animals
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.
- Climate
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.
- Tech
Greening your digital life
The less electricity you use while playing video games or using your devices, the less impact you’ll have on climate change.
- Environment
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.
- Earth
Explainer: What are aerosols?
We may not see them, but tiny particles and droplets cloud the air, affecting its properties. Some may be pollutants, others all-natural products.
- 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.
- Climate
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.
- Environment
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.
- Computing
Explainer: What is an algorithm?
These step-by-step instructions underlie social media, internet searches and other computer-based activities. But what are they exactly? We explain.
