Hurricane Intensity

Florida State
Lead author: James Elsner
Where published: American Geophysical Union
Climate change is affecting the intensity of Atlantic hurricanes, and hurricane damage likely will continue to increase because of greenhouse warming ... future hurricane hazard mitigation efforts should reflect that hurricane damage will continue to increase, in part, due to greenhouse warming

Undersea Methane

University of California Santa Barbara
Lead author: Ira Leifer
Where published: Global Biogeochemical Cycles
If the world continues to get warmer, vast amounts of methane gas trapped in ice under the sea could belch up and worsen climate change ... The study measured the amount of methane that escaped to the atmosphere ... It found that virtually all of the methane escaping from the deep water reached the atmosphere, countering some theories that methane seeps out in tiny bubbles that harmlessly dissolve in the ocean ... rising temperatures could warm the oceans, creating a feedback loop

Greenland Ice Melting

University of Texas
Lead author: Byron Tapley
Where Published: Science Magazine
New data shows that Greenland's ice sheets are melting faster than before. Researchers interpreted the data from NASA satellites ... this melting will disrupt the ocean current in the northern hemisphere, which in turn will change the global climate system

Increasing Methane Levels

Laboratoire des Sciences du Climat et de l'Environnement
Lead author: P. Bousquet
Where published: Nature
Methane is an important greenhouse gas, and its atmospheric concentration has nearly tripled since pre-industrial times ... Remarkably, this growth rate has decreased markedly since the early 1990s, and the level of methane has remained relatively constant since 1999, leading to a downward revision of its projected influence on global temperatures ... Since 1999, however, they indicate that anthropogenic emissions of methane have risen again.
