    Warning: Wildfires might make you itch

    Western wildfires are on the rise due to climate change and land use. Now a study adds eczema to the list of health risks that smoke might trigger.

    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.

    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.

    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.

    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.

    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.

    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.

    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.
