The ocean has a long memory. When the water in today’s deep Pacific Ocean last saw sunlight, Charlemagne was the Holy Roman Emperor, the Song Dynasty ruled China and Oxford University had just held its very first class. During that time, between the 9th and 12th centuries, the earth’s climate was generally warmer before the cold of the Little Ice Age settled in around the 16th century. Now ocean surface temperatures are back on the rise but the question is, do the deepest parts of the ocean know that?
A new study of prehistoric hurricanes shows the intensity and frequency of hurricanes the U.S. could experience could intensify as ocean temperatures increase with climate change.
In a study published this week in Nature Geoscience, a team of researchers provides new insight into the behavior of the African monsoon at the end of the African Humid Period and the factors that caused it to collapse.
As California finally experiences the arrival of a rain-bearing Pineapple Express this week, two climate scientists from the University of Minnesota and Woods Hole Oceanographic Institution have shown that the drought of 2012-2014 has been the worst in 1,200 years.
Ten science reporters, writers, and multimedia journalists from the U.S., Canada, and India have been selected to participate in the competitive Woods Hole Oceanographic Institution (WHOI) Ocean Science Journalism Fellowship program. The program takes place September 8-13, 2013, in Woods Hole, Mass., on Cape Cod.
How will rainfall patterns across the tropical Indian and Pacific regions change in a future warming world? Climate models generally suggest that the tropics as a whole will get wetter, but the models don’t always agree on where rainfall patterns will shift in particular regions within the tropics.
When Woods Hole Oceanographic Institution (WHOI) marine paleoecologist Marco Coolen was mining through vast amounts of genetic data from the Black Sea sediment record, he was amazed about the variety of past plankton species that left behind their genetic makeup (i.e., the plankton paleome).
WHOI geologist Liviu Giosan and an international team of collaborators including environmental engineers, modelers, paleogeographers, and paleobiologists have pieced together a unique history of the Danube River delta and watershed that ultimately provides evidence for a transformative impact of humans on the Black Sea over hundreds, if not thousands of years.
A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago. The study, led by WHOI geologist Liviu Giosan, also resolves a long-standing debate over the source and fate of the Sarasvati, the sacred river of Hindu mythology.
A fundamental shift in the Indian monsoon has occurred over the last few millennia, from a steady humid monsoon that favored lush vegetation to extended periods of drought, reports a new study led by researchers at the Woods Hole Oceanographic Institution. The study has implications for our understanding of the monsoon’s response to climate change.
New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, says a research team led by the Woods Hole Oceanographic Institution (WHOI).
A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today.
Scientists have offered several competing theories for what led to the extinction of the Neanderthals, with much of the debate focusing on the relative roles of climate change versus conflict with modern humans. New research shows that Neanderthals did not die out at a time of extreme and sudden climatic change, as some researchers have suggested.
The frequency of intense hurricanes in the Atlantic Ocean appears to be closely connected to long-term trends in the El Niño/Southern Oscillation and the African monsoon, according to new research from the Woods Hole Oceanographic Institution (WHOI). Geologists Jeff Donnelly and Jonathan Woodruff made that discovery while assembling the longest-ever record of hurricane strikes in the Atlantic basin.
Arctic coastal environments are some of the most vulnerable to climate change. A team of WHOI researchers visited Canada’s Mackenzie River Delta in April 2007 to find out just how vulnerable.
Climate is often discussed in global terms, but it is the regional and local effects that will matter most to everyday people.
Scientists have found links in global variations in temperature that
may provide insight to the bigger picture of climate change.
Scientists have found evidence that tropical Atlantic Ocean temperatures may have once reached 107°F, about 25°F higher than ocean temperatures today and warmer than a hot tub. While these high ocean temperatures occurred millions of year ago, the new study suggests climate models underestimate future warming.
New scientific findings are strengthening the case that rapid climate change may be related to how vigorously ocean currents move heat between low and high latitude.
Corals from Papua New Guinea and Barbados indicate that changes in sea level, one of the key indexes for global climate change, may have been more frequent in the past than previously thought.
