Setiment in Louisiana


NASA satellites continually monitor the Earth, snapping photos and sending information to researchers on the ground.

Most of the time, things seem to be more or less the same as they were the day before, but the Earth is actually constantly changing. Sometimes it changes through discrete events, like landslides and floods. Other times, long-term trends, such as climate change, slowly reshape the land in ways that are difficult to see.

Extreme meteorologist Reed Timmer's drone footage offers incredible detail of an F3 tornado.

I'd never seen a green sky before living in the Midwest. I also didn't know the difference between a tornado watch and a tornado warning, and it took me a while to keep it straight. (A "watch" means the conditions are ripe for a tornado to form, a "warning" means one has been spotted.)

I learned that green sky spelled trouble, so when we saw ominous greenish clouds gathering one afternoon, we knew to turn on the TV. A tornado watch had been issued in our area, which then turned to a warning.

Then the tornado siren sounded outside. Time to take cover.

We didn't have a basement, so my husband and I grabbed our 4-year-old and shut ourselves into our first-floor bathroom, the only room in our townhome without any windows. The wind began to howl, getting louder and louder until it didn't sound like wind anymore. Imagine static blaring on a TV, only with more layers, both deeper and higher-pitched. The sliding glass door in our dining room rattled. Our daughter cried and I prayed. It lasted maybe five or ten minutes.

The UK is experiencing record-breaking weather this week. England reached its hottest temperature of the year on Tuesday when it hit 32.2°C at Heathrow Airport in west London. Temperatures in Northern Ireland reached an all-time high when 31.3°C was recorded at Castlederg the next day.

However, when you translate Celsius to Fahrenheit, the temperatures don't seem to be that extreme, at least to an American. Thirty-two degrees celsius is only 89.6° F. When you compare the temperatures in the UK to an average July day in Las Vegas, Nevada where it'll hit 107°F, the British seem a little weak.

A polar vortex swept through the southern United States this week, bringing snow and ice storms and record low temperatures that have debilitated the region. Texas in particular has been hit hard, and with an energy infrastructure that's not designed or prepared for such weather, millions of people have been without power for days.

People who aren't used to cold weather, who live in homes that aren't designed to retain heat, who don't have winter gear to keep them warm, are struggling to stay warm without power and heat. Some don't have water, either.

While politicians bicker over who is to blame for the dire situation, Americans are doing what they can to help. For those of us in the north, that means sharing knowledge and experience for how to stay warm when the heat goes out.

Several viral threads on Twitter have proven incredibly helpful as people offer their best tips for handling the frigid temperatures while staying safe. (Sadly, we've seen several deaths from carbon monoxide poisoning—running a car in a garage and heating a home with a charcoal grill are things you should avoid at all costs.)
