HMS Challenger Expedition (1872 to 1876) — The Greatest Scientific Venture of the 18th and 19th Century

By Oceans, Uncategorized

HMS Challenger Expedition gave us exceptional baseline data for 21st century ocean warming evaluation. Average global ocean temperature change is  0.59 degrees C. The Royal Society, University of Edinburgh and Mechiston Castle School sponsored the expedition around the globe to explore the deep oceans. Led by Captain George Nares, the expedition is credited with the…

North Atlantic Current Change in Mid 20th Century

By Oceans

These biogeochemists are getting smarter everyday. Now they have determined how to identify different species of nitrogen that have been created in different areas.  Tropical waters create one kind of nitrogen, polar waters create another. Deep water corals utilize nitrogen in growth.  These researchers have sampled deep water corals in the northwest Atlantic off of…

How do we curb emissions with the way our society has evolved? Really. I mean serious curbing; enough to prevent dangerous climate change? When considering the answer, dangerous climate change must be clearly defined. So, what exactly is dangerous climate change?

The Upper 700 Meters of Ocean has Warmed More Than the Heat Generated by 2 Billion Atomic Bombs Similar to the Hiroshima Bomb

By Oceans

May 21, 2010 From Science News: "Earth’s upper ocean warmed substantially between 1993 and 2008, a new analysis reveals. The trend signals growing heat storage in oceans, researchers say, a result of human-caused warming. The new study, reported in the May 20 Nature, combined oceanographic data gathered worldwide between 1993 and 2008, the time period…

European Science Foundation – Oceans are already 30% More Acidic Than They Were 200 Years Ago. "Ocean acidification is more rapid than any time in the last 35 million years."

By Oceans

The Oceans are our largest natural sink for CO2. They absorb excess carbon dioxide from our atmosphere, but the oceans become more polluted as they absorb more CO2. It’s like a bioaccumulating toxin. CO2 is the mercury of our ocean’s water. The CO2 pollutes our oceans just like it pollutes our skies. Ocean acidity is…

Warmest Oceans Ever Recorded

By Oceans

August 14, 2009, NOAA’s global temperature report shows that our Earth’s oceans are now warmer than they have been since record keeping began in the 1880s. The combined land /ocean temperature for July 2009 was 1.03 degrees above the 20th century average of 60.4 degrees F or the fifth warmest ever recorded. The global ocean…

"We’ve lost 80 per cent of the living coral cover in the Caribbean over the last four decades" says Dr. Nicholas Dulvy of the Simon Fraser University

By Oceans

The study reviewed nearly 500 surveys of 200 different reefs all cross the Caribbean between 1969 and 2008. The causes are varied and all are directly attributable to climate change. This discovery is devastating beyond belief. We new this could happen on a warmer planet, and we new that our coral reefs were being impacted…

"Ocean acidification, one of the world’s most important climate change challenges, may be left off the agenda at the United Nations Copenhagen conference." Says the National Science Academies of 70 nations

By Oceans

The science academies of 70 nations addressed the opening of the climate talks in Bonn today concerning the seriousness of emission cuts required to keep ocean acidity under control. From the statement: Ocean acidification is irreversible on timescales of at least tens of thousands of years; At current emission rates models suggest that all coral…

More Ocean Productivity Decline

By Oceans

A study in Science on the 13th shows a 12% average decline in ocean productivity along the western Antarctic Peninsula in the last 30 years. Temperatures have increased here 4.6 times the global average. In the last few years of the study (beginning about the time the Big Melt began in Greenland – about 2004)…
