Some coastlines are more resilient to sea level rise, whereas others just plain drown. A new study by geologists at the United States Geological Survey evaluate how coastlines along the northeast United States will respond to sea level rise.
New research reports a change in the primary driver of global sea level rise. Natural climate influences on sea level rise are no longer at fault, and haven’t been since the middle of the 20th century.
A classic climate “Whodunit”? Can researchers get to the bottom of the mystery of the cooling eastern Pacific Ocean, three decades in the making?
Will salt marshes survive sea level rise? Previous studies have emphatically answered “No!” suggesting a 20-50% loss by the year 2100. However, Kirwan and colleagues have challenged this notion, finding that salt marshes are not nearly as fragile as previously thought, and that salt marshes will not succumb to the rising sea without a fight!
Oil seeps are naturally occurring sources of oil to the marine environment. This study looks at the impacts of oil seeps on chlorophyll concentrations near the surface of the ocean and the results are pretty slick!
Melting Antarctic glaciers have major consequences on global climate. In this study, climate simulations reveal a seesaw like behavior where cooling near the south pole means warming near the north pole.
Lower amounts of sea ice in the North Atlantic disrupts the way heat is transferred, a key factor that changes large-scale ocean circulation with major global climate consequences.
Future sea level rise poses many challenges for communities on barrier islands. However, sea level rise alone may not be the only factor that determines the fate of barrier islands in a future of rising seas.
Less frequent hurricanes can be expected due to climate change, a surprising finding considering the long list of challenges. Sound too good to be true? Unfortunately, the trade-off can be filed under that list of challenges.
Satellite altimetry: talk about a game-changer! Measurement of the oceans’ sea surface height by satellite altimetry has revolutionized the study of sea level rise. But even the most precise measurements are prone to error, which can drastically impair our understanding of sea level rise.
Two hot items in climate science today are the North American drought and the decade-long warming hiatus. This study finds a relationship between these two headliners and seeks to answer the question: Are humans responsible for the drought?
Calculating a global average change in sea-level over the twentieth-century is no walk in the park. This study uses a new technique to critically look at previous estimates of sea-level rise. The findings suggest that previous estimates may have been too high, but what does this mean for future sea-level rise projections?
From 2009-2010, the Northeast coast of North America experienced approximately four inches of sea-level rise, quite the departure from the 2.5 mm per year annual average rate of rise. Researchers link this leap in sea-level to changes in Atlantic Ocean circulation and atmospheric pressure gradients. Will extreme sea-level rise events continue to be the exception, rather than the rule?
Here at Oceanbites, we hope you have been enjoying your stay in the Holocene Epoch, a span of time ranging from present day to 11.7 thousand years ago. The Holocene has been praised for its warm and stable climate compared to the past glacial period. But more and more evidence suggests that the early Holocene was a bit more variable, with notable changes in the North Atlantic Ocean’s surface and deep water circulation.
How stable are the barrier islands that outline many coastal communities around the world? To answer this question, scientists look at the relationship between barrier island elevation and the plant life that populates the dunes.
A powerful offshore earthquake was quickly identified as the source of the catastrophic 2011 Tohoku tsunami, which devastated portions of coastal Japan. Numerous studies have shown that an earthquake was not the sole contributor to the tsunami and that an unidentified tsunami source remains at large. New research has identified a second suspect.
What is natural and what is human induced climate change? A controversial topic indeed, determining when a natural process has been drastically altered by human activities is best left to the scientists! In this study, scientists use climate model simulations and sea level projections to estimate when human induced climate change emerges from natural variability.
Researchers are using centuries of tree growth data to understand variability in upwelling, productivity and marine ecosystem health in the California Current.
From the early 1990s on, the Earth has been experiencing a global warming hiatus, where the post-industrial warming trend has effectively come to a stop. Recent research has implicated strengthening Pacific trade winds as the cause of the warming hiatus. New evidence suggests the mechanism triggering the unprecedented acceleration of Pacific trade winds has its origins in the Atlantic Ocean.
