When I think back to Super Typhoon Haiyan, I often think of this image. It was captured from space by American astronaut Karen Nyberg.
Haiyan was one of the world’s most powerful storms in history, and you can see its sheer strength in that snapshot from orbit.
The super typhoon generated a storm surge as high as five meters. It roared ashore and wiped entire communities away. In the end, more than 6,000 people were killed and almost 4 million people displaced.
But Haiyan's legacy is more than a death toll. It’s more than shocking pictures of the storm’s strength or the devastation it caused.
It’s about the fate of millions of already impoverished people who lost their homes, livelihoods and loved ones.
Cristina Gonzales Romualdez says she didn't expect that much water.
She's a city councillor in Tacloban, which took a direct hit from Typhoon Haiyan. She's also the wife of mayor Alfred Romualdez.
But more importantly, on the day of storm, she's a mother of two.
Gonzales Romualdez says she and her daughters swam to safety. She told Kristie Lu Stout that she prayed the entire time, and fought to keep calm for her children.
Watch the video for her dramatic account how it all happened.
Your smart phone is smarter than you think.
The UK-based OpenSignal has developed an app that crowd sources the weather using data from your mobile battery.
That's right, you can tell how hot it is outside thanks your cellphone's energy source. That's because smartphones have built-in thermometers to track battery temperature to help prevent overheating.
It's something the company discovered by accident. A year ago, OpenSignal discovered a strong correlation between battery temperature and daily temperatures recorded at a weather station.
Its WeatherSignal app, available for Android phones, crowd sources the temperature data from thousands of users who are running the app.
How accurate is the data? And will it be able to predict the weather one day?

Sinkholes happen fairly often in Florida. But rarely do they occur with such drama.
A 36-year-old man is presumed dead after a sinkhole suddenly opened beneath his bedroom Thursday night. The victim's brother says the crash of the collapse sounded like a car driving through the house.
The sinkhole in suburban Tampa was originally reported to be 100 feet (30 meters) across. An engineer says that is actually the diameter of the safety zone, while the sinkhole is about 20 to 30 feet across.
Sinkholes can suddenly happen when bedrock dissolves but the surface stays intact. The void eventually collapses.
Authorities in Florida currently believe this one happened naturally, meaning the rock was probably eroded away by groundwater. Sometimes manmade situations, such as water main breaks, can be responsible.
China's capital has adopted emergency response measures to deal with record smog.
People in Beijing say the air tastes like coal dust and car fumes.
According to state media, the city will remain covered in gray until Wednesday, when the wind will sweep in to the rescue and blow the smog away.
As of 2 pm EDT, Hurricane Sandy packed 145 kph (90 mph) winds. At the time, 23 states had issued a Warning or Advisory for wind related to Sandy’s circulation.
The storm is expected to make landfall later Monday evening.
Based on pressure, Sandy is likely to be the strongest storm to make landfall north of Cape Hatteras, North Carolina.
When it hits, Sandy will be undergoing a transition from a "tropical cyclone" to a "wintertime cyclone." Mari Ramos explains the difference.
Sandy’s field of tropical storm-force or greater winds extends nearly
620 1,600 kilometers (1000 miles). That's roughly twice the size of the U.S. state of Texas.
To put it another way, if that wind field were a country, it would be the 20th largest country in the world.
