Closing critical gap in weather forecasting
Scientists working on the next frontier of weather forecasting are hoping that weather conditions 3-to-4 weeks out will soon be as readily available as seven-day forecasts. Having this type of weather information--called subseasonal forecasts--in the hands of the public and emergency managers can provide the critical lead time necessary to prepare for natural hazards like heat waves or the next polar vortex.

Peatlands trap CO2, even during droughts
Scientists studied the two species of moss that make up the peatland. They discovered that in hot weather and drought conditions, one species resists, whereas the other is negatively impacted. In wet weather conditions the opposite takes place. Peatland however survives in the end. Although peatlands make up only 3% of the Earth's surface, they store one third of CO2 present in soil.
