  • The inexorable rise of the waters of the earth’s oceans since 1880 has already contributed almost 20 cm (nearly a foot) since 1880, and more recently the rise continues at an accelerating pace . The IPCC (2007) predicts an increase of sea level of between 0.5 to 1.5 m by the year 2100
  • Island nations under threat include Bermuda and the Bahamas in the Atlantic, the Pacific Islands of Palmerston, Tuvalu, Kiribati, Vanuatu, Marshall Islands, Cook Islands, Fiji, Solomon Islands, and the Maldives in the Indian Ocean
  • in terms of numbers of persons impacted, the oceanic islands pale in comparison with the slow-motion disasters that will occur in densely populated, low-lying coastal cities like New Orleans, New York, Los Angeles, Tokyo, Amsterdam, Mumbai, Shanghai, Singapore, Jakarta and Dhaka.

  • The extraordinary warming of 2.5°C (4.5°F) over the past 50 years on the Antarctic Peninsula is both the world’s greatest temperature change and least opportune venue for warming on the planet. Warmer air and currents penetrating deep into West Antarctica could initiate collapse of the marine based West Antarctic Ice Sheet ice sheet (Joughin and Alley, 2011), rapidly elevating global seas by as much as 3-6 meters.

  • whole countries such as Mauritius and Tuvalu will need to evacuate due to rising sea levels. But while coastlines in much of the world may suffer, climate change will be a positive development in some areas. Specifically, Canada; northern Europe; Russia; Alaska; Patagonia, Argentina; and southern Africa may all experience real estate booms.
  • Continuing with the New York example, Mayor Michael Bloomberg recently proposed a $20 billion climate change plan for the city.
  • The plan is designed to mitigate damage from another Sandy-sized storm and would drastically change everyday life for New Yorkers, with sharply increased taxes and large construction projects in most seaside neighborhoods.

  • new cities, which would cater to the “well-heeled,” would be built in places where rising sea levels would actually improve local climates. Rising temperatures and an increase in arable land as a result of climate change is expected to occur in Russia, Canada, Scandinavia, Chile, Argentina, southern Africa, the Great Lakes region
  • cities would also make use of newer technologies. Self-driving cars, for example, will transform living patterns due to convoy features that sharply reduce both commute times and greenhouse gas consumption

    Scientists in Australia have reported the discovery of huge freshwater reserves preserved in aquifers under the world's oceans. The water has remained shielded from seawater thanks to the accumulation of a protective layer of sediment and clay. And it's not a local phenomenon. Such reserves are to be found under continental shelves off Australia, China, North America and South Africa.Scientists in Australia have reported the discovery of huge freshwater reserves preserved in aquifers under the world's oceans.

  • A newly-discovered bacterium that feeds on plastic could help develop new recycling methods.
  • The discovery was made by researchers from Japan, who say that the microorganism is remarkable for its ability to breakdown completely a common type of plastic known as PET. This digestive process is slow, and the short-term implications of the discovery are uncertain, but studying the bacterium — which has been given the name Ideonella sakaiensis — could lead to new ways to safely get rid of junk material.
  • It's thought that plastic bottles take 450 years to break down, and although some plastics do degrade quicker in the ocean, this just leads to more chemical pollution.
