Ever wanted to fly over the eye of a hurricane? NASA's unmanned plane, the Global Hawk, did just that, last week. It's not just for fun - it's all in the name of storm research.

09.08.10 |
What do fires and mountain pine beetles have in common? More than you might think. In recent years, pine beetle numbers have skyrocketed. So has the risk of wildfires. University of Wisconsin forest ecologist Phil Townsend uses Landsat satellite data to suggest that climate change might be the missing link.

| No calm, just storm |
09.02.10 |
With the peak of the 2010 Atlantic hurricane season still 10 days away, the relative calm of the first half of the season has quickly evaporated. There are now three named tropical cyclones in the Atlantic-Hurricane Earl and Tropical Storms Fiona and Gaston. NASA is hard at work forecasting and tracking these monster storms.

08.10.10 |
As Earth's global temperature continues to rise, water vapor — the most abundant greenhouse gas on Earth, which traps heat much as carbon dioxide does — will continue to build, with uncertain results. What does this mean for the future of clouds?

| Burning question |
08.03.10 |
Our ability to predict the future climate is far from certain, but research suggests that the question of whether global warming will turn out to be less severe than scientists think may be less relevant than whether it may be far worse.

Antarctica may not be the world's largest landmass -- it's the fifth-largest continent -- but resting on top of that land is the world's largest ice sheet. That ice holds more than 60 percent of Earth's fresh water and carries the potential to significantly raise sea level.

| Just 5 questions: What lies beneath |
06.01.10 |
Permafrost is not your garden-variety soil. Beneath the frozen depths of the Arctic, the icy soil stores an estimated 1.5 trillion tons of carbon - methane and other hydrocarbons - twice as much as is found in the atmosphere.

The ocean has helped slow the effects of global warming by absorbing much of the excess heat-trapping carbon dioxide that has been going into the atmosphere since the start of the Industrial Revolution. All that extra carbon dioxide, however, has been a bitter pill for the ocean to swallow.

Efforts to harness the energy potential of Earth's ocean winds could soon gain an important new tool: global satellite maps from NASA. Scientists have been creating maps using nearly a decade of data from NASA's QuikScat satellite that reveal ocean areas where winds could produce energy.

Size doesn't always equal importance, but in the case of Earth's ocean, it does. So when a college student piped up with “It’s big!” as the answer to a question about why one should study the ocean, his professor agreed. In fact, he would argue that “it’s big” is one of the most significant things we should know about the ocean.

Scientists hope a new follow-on mission to the Jason-1 and Topex/Poseidon satellite missions, equipped with the latest high-tech instruments, will bring them closer to answering broad fundamental questions: How does ocean circulation vary from season to season, from year to year and from decade to decade? How much can the ocean change from natural and human-induced causes? In what ways does the ocean impact human activities?
