Earthquakes May Endanger New York More than Thought
August 21 — A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. (The Earth Institute at Columbia University press release) More

Satellite Images Show Continued Breakup of Two of Greenland's Largest Glaciers
August 20 — Researchers monitoring daily satellite images here of Greenland's glaciers have discovered break-ups at two of the largest glaciers in the last month. (Ohio State University press release) More

Drier, Warmer Springs in U.S. Southwest Stem from Human-Caused Changes in Winds
August 19 — Human-driven changes in the westerly winds are bringing hotter and drier springs to the American Southwest, according to new research. (University of Arizona press release) More

Dirty Smoke From Ships Found to Degrade Air Quality in Coastal Cities
August 18 — Chemists have measured for the first time the impact that dirty smoke from ships cruising at sea and generating electricity in port can have on the air quality of coastal cities. (University of California - San Diego press release) More

Greenland Ice Core Reveals History of Pollution in the Arctic
August 18 — New research finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions. (National Science Foundation press release) More

Study Shows Continued Spread of 'Dead Zones'
August 14 — A new study shows that the number of "dead zones" – areas of seafloor with too little oxygen for most marine life – has increased by a third between 1995 and 2007. (Virginia Institute of Marine Science press release) More

Climate Change: When it Rains it (Really) Pours
August 7 — A new study provides the first observational evidence to confirm the link between a warmer climate and more powerful rainstorms. (University of Miami Rosenstiel School of Marine & Atmospheric Science press release) More

Rare Antarctic Fossils Reveal Extinction of Tundra Before Full Polar Climate Arrived
August 5 — An unusual and amazing discovery of fossilized plants and insects in an ice-free region of Antarctica reveals the last traces of tundra before a dramatic and abrupt cooling some 14 million years ago. (Boston University press release) More

Patagonian Glacier Yields Clues for Improved Understanding of Global Climate Change
August 4 — Patagonia was thought to be subjected mainly to westerly winds off the Pacific, but a dual ice core analysis yielded the first evidence that this region also comes under the influence of meteorological regimes that arise further south, in the Antarctic. (Institut de Recherche Pour le Développement press release) More

Pacific Shellfish Ready to Invade Atlantic
August 4 — As the Arctic Ocean warms this century, shellfish, snails and other animals from the Pacific Ocean will resume an invasion of the northern Atlantic that was interrupted by cooling conditions three million years ago. (University of California - Davis press release) More

Tracking Down Abrupt Climate Changes
August 1 — Research suggests that extreme cooling that occurred within a short number of years 12,700 years ago was associated with a sudden change in the wind systems. (Helmholtz Association of German Research Centres press release) More
