Rising acidity erodes Alaska's fisheries
Friday, August 21 2009

Alaska's marine waters - source of 60 percent of the United States' seafood harvest - show surprising impact as greenhouse emissions undermine the base of the food web.

The Arctic's increased vulnerability to climate change is not limited to higher temperatures and melting permafrost.

New research from the University of Alaska Fairbanks suggests Arctic oceans are particularly susceptible to acidification, with potentially dire consequences to Alaska's rich crab and salmon fisheries.

"Everything is acting in unison on the environment – it's not just the ice loss or the warming or the acidification," said UAF chemical oceanographer Jeremy Mathis. "The Arctic is taking a multilateral hit."

Solar Cycle Linked to Global Climate, Drives Events Similar to El Niño, La Niña
July 16, 2009

New research shows that maximum solar activity and its aftermath have impacts on Earth that resemble La Niña and El Niño events in the tropical Pacific Ocean. The findings may pave the way toward better weather predictions.

"In AD 1000, the Earth was experiencing an episode of climate warming similar to that of the present day. Temperatures in many parts of the world seem to have risen by at least two or three degrees Fahrenheit. Although the scale of this "global warming" may seem small, its effects on human societies were profound. In Europe, several centuries of long hot summers led to an almost unbroken string of good harvests, and both urban and rural populations began to grow. These centuries are known as the Medieval Warm Period. One of the more dramatic consequences of the Medieval Warm Period was the expansion of Viking settlements in the North Atlantic. From their Icelandic base (established in AD 870), the Norse people began to move west and north to Greenland, Canada, and eventually above the Arctic Circle."

"The Medieval Warm Period was a time of warm weather around 800-1300 AD, during the European Medieval period. Initial research on the MWP and the following Little Ice Age (LIA) was largely done in Europe, where the phenomenon was most obvious and clearly documented. The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north."

"The climate at this time was very warm, much warmer than it is today, and crops were able to do well. It seems likely that the name "Greenland" was given to the country, not just as wishful thinking, but because it was a climatic fact at that time. The mild climatic period was fairly short-lived in geologic terms - by about 1200 AD, the ever-increasing cold was making life extremely difficult, and some years no supply ships were able to reach Greenland through the ice-choked seas. During this period, Norway had assumed responsibility for supplying the Norse settlers in Greenland, but as the climate worsened it became a very difficult task."

"At that time, the inner regions of the long fjords where the settlements where located were very different from today. Excavations show that there were considerable birch woods with trees up to 4 to 6 meters high in the area around the inner parts of the Tunuliarfik- and Aniaaq-fjords, the central area of the Eastern settlement, and the hills were grown with grass and willow brushes. This was due to the medieval climate optimum. The Norse soon changed the vegetation by cutting down the trees to use as building material and for heating and by extensive sheep and goat grazing during summer and winter. The climate in Greenland was much warmer during the first centuries of settlement but became increasingly colder in the 14th and 15th centuries with the approaching period of colder weather known as the Little Ice Age."

"The Medieval Warm Period coincides with the Vikings' settlement of Greenland, Iceland and possibly North America. Farmsteads with dairy cattle, pigs, sheep and goats were prevalent in Iceland and along the southern coast of Greenland. Even England was able to compete economically with France in wine production. On the other hand, agriculture steadily declined at higher latitudes during the Little Ice Age, while mortality rates and famines increased. By 1500, settlements in Greenland had vanished and the inhabitants of Iceland were struggling to survive."

"During the 9th & 10th centuries the Vikings reached Iceland and Greenland during the milder condition that prevailed during Medieval Warm Period. Norse settlers arrived in Iceland in the 9th and Greenland in the 10th century with an agricultural practice based on milk, meat and fibre from cattle, sheep, and goats. The settlers were attracted by green fields and a relatively good climate and driven there by population pressures in Scandinavia. They were able to sail to Iceland and Greenland as well as Labrador because of a decrease in sea ice in the North Atlantic."

"The Medieval Warm Period was a time of unusually warm climate in Europe from about 850 until 1250 AD. The warm climate overlaps with a time of high solar activity called the Medieval Maximum. The warmer climate caused historic events such as the spread of Viking settlements in Northern Europe. The Vikings were likely better able to explore and colonize many areas in Northern Europe during this time because the warm climate. They traveled by boats to Greenland among other places through seas that, with cooler climates are typically full of dangerous sea ice. During this time, grape vineyards, which require moderate temperatures and a long growing season, were as far north as England. In comparison, today grapes vineyards are only typically as far north as France in Europe."

"Between the 9th and 14th century there was a "Medieval Warm Period", when the average temperature in the Northern Hemisphere reached its highest point in the past 4,000 years, which was only about 1°C higher than at present. It has been documented that during this period, American oysters (Crassostrea virginica) and bay scallops (Aequipecten irradiens) formed populations as far north as Sable Island. Neither of these species exists there today. Radiocarbon dating of relict oyster and bay scallop shells compare reasonably well with the dates of the post-glacial warm period. From the 16th to the 19th century there was a "Little Ice Age", when the average temperature of the Northern Hemisphere was a degree or two cooler than now. It is during this time that salmon are hypothesized to have relocated to the New England area. Salmon may have migrated from Europe after the end of the Pleistocene, across the Atlantic. Immediately prior to the Little Ice Age, the Medieval Warm Period diminished sea pack ice around Iceland and Greenland."
