California is particularly earthquake-prone, hosting the great San Andreas fault zone.
Can California's wet weather make earthquakes more likely? Scientists are still learning about what triggers these events. Even human activity can be a culprit.

2016 is the third consecutive hottest year on record. How can we adapt?
Sixteen of the 17 hottest years have occurred this century and we know it’s because of a changing climate, not changes in weather.
For the third consecutive year, it's the hottest year ever. A climate scientist explains how these predictions are made and why they're completely different from forecasting the weather.

Very powerful, try to avoid.
Lightning strikes are powerful – but we haven't had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.
After the storm … Researchers are working together to predict future outbreaks of thunderstorm asthma.
Researchers from a range of disciplines need to work together if we are to predict and prepare for the next thunderstorm asthma event.
