Six Answers to Questions You’re Too Embarrassed to Ask about the Hottest Year on Record

You may have seen the news that 2023 was the hottest year in NASA’s record, continuing a trend of warming global temperatures. But have you ever wondered what in the world that actually means and how we know?We talked to some of our climate scientists to get clarity on what a temperature record is, what happened in 2023, and what we can expect to happen in the future… so you don’t have to! You may have seen the news that 2023 was the hottest year in NASA’s record, continuing a trend of warming...

Confirmed: Summer 2023 Hottest in NASA’s Record

All three months of summer 2023 broke records. July 2023 was the hottest month ever recorded, and the hottest July. June 2023 was the hottest June, and August 2023 was the hottest August.NASA’s temperature record, GISTEMP, starts in 1880, when consistent, modern recordkeeping became possible. Our record uses millions of measurements of surface temperature from weather stations, ships and ocean buoys, and Antarctic research stations. Other agencies and organizations who keep similar global temper...

Why Isn’t Every Year the Warmest Year on Record?

This just in: 2022 effectively tied for the fifth warmest year since 1880, when our record starts. Here at NASA, we work with our partners at NOAA to track temperatures across Earth’s entire surface, to keep a global record of how our planet is changing.The warming comes directly from human activities – specifically, the release of greenhouse gases like carbon dioxide from burning fossil fuels. We started burning fossil fuels in earnest during the Industrial Revolution. Activities like driving c...

We Need to Talk About Migraine Stigma

The first day I set aside to write this article, I instead spent curled up on my couch, in the dark, with Netflix playing softly in the background. I had a migraine, and it made writing impossible. Really, it made it impossible to do anything more than lie under my weighted blanket and shuffle back and forth to the kitchen for seltzer. If you've never had a migraine, it might seem surprising that a headache could knock me down so hard. But migraine is so much more than a headache. It’s a serio

Life Hack for People With Chronic Illness: Write an Elevator Pitch. Here’s Why.

A few months ago, I popped a blood vessel in my eye. I was in the middle of a migraine—a common experience for me—but the eye thing was new. I panicked. Was I having a stroke? I wanted a qualified medical professional to tell me I wasn’t dying. The telehealth doctor I called spent most of our 10-minute virtual appointment assuring me that migraines aren’t fatal. I was scattered and scared, and I couldn’t get across to him that I know what a migraine is. I have chronic migraines, but I felt too

Taking in Some Arctic Air – NASA Earth Expeditions

by Katy Mersmann / SKIES OVER ALASKA AND CANADA / The Arctic Boreal and Vulnerability Experiment (ABoVE) covers 2.5 million square miles of tundra, forests, permafrost and lakes in Alaska and Northwestern Canada. ABoVE scientists are using satellites and aircraft to study this formidable terrain as it changes in a warming climate. In some ways, NASA’s DC-8 feels like a commercial airplane, with its blue leather seats and tiny bathrooms in the back. But once the plane starts to spiral down over

In Arctic Tundra, It’s Getting Easy Being Green – NASA Earth Expeditions

As I walk up the Alpine Trail in Denali National Park, I can see the vegetation changing before my eyes. Deciduous plants, like willows and smaller shrubs, start huge, as tall as my head and shoulders. But as the trail leads up, and as the altitude grows, the vegetation shrinks. Over the course of the roughly 1,300-foot elevation gain, the plant life gets shorter and shorter until suddenly it’s almost gone—we’ve reached the tundra. By climbing up the side of this hill, we’ve mimicked traveling

The Fact and Fiction of Martian Dust Storms

For years, science fiction writers from Edgar Rice Burroughs to C. S. Lewis have imagined what it would be like for humans to walk on Mars. As mankind comes closer to taking its first steps on the Red Planet, authors' depictions of the experience have become more realistic. Andy Weir's "The Martian" begins with a massive dust storm that strands fictional astronaut Mark Watney on Mars. In the scene, powerful wind rips an antenna out of a piece of equipment and destroys parts of the astronauts' c

How we created our Futures Lab update in a vertical video format | RJI

From the beginning we knew we wanted our report on non-horizontal video to be presented in a vertical frame. This would enable us to provide an example of how an entire show would look in that shape, since few news organizations have deliberately created video this way. (The closest things we could find were the square videos in places like Instagram, Vine, Facebook, etc.; vertical content posted in SnapChat, which contains mostly on-the-scene footage; and a single vertical video example posted

Q&A: Stalking and Moving On

As women in media, we often face unique threats to our well-being and safety, both in person and online. That’s why we’re hosting Stepping Up Safety: A Panel on Personal Security in the Field and Workplace on October 7. Leading up to the panel, we’ve asked industry professionals to share their stories, advice and personal experiences. Lola Alapo works in public relations for a university in the South.
