Open letter to arch-enemy Billionaire Charles Koch now on Youtube! Charles Koch you suck!

This i found on Youtube when i was ACTUALLY researching the StreetArtist BANKSY,DeWeaver and Banksy are old mates and oddly enough have the same sort of furious rage against big corporations.This was on DeWeaver's blog.
He's taking on BILLIONAIRES people!we need to get behind people like him and others if we're ever gonna get some change!
DeWeaver:"I felt this video completely necessary for the Koch brothers, my feelings on these two are hardly any secret by now, the video is completely appropriate for these two low lifes"!

Global warming intensifying global water cycle by double current climate model projections

New research into ocean salinity levels has revealed a strong global water cycle intensification during the period of 1950 to 2000. The researchers report the rate of change in the global water cycle is double the rate projected by current-generation climate models. The study found "robust evidence of an intensified global water cycle at a rate of about eight per cent per degree of surface warming," said study co-author Dr Durack, a post-doctoral fellow at the Lawrence Livermore National Laboratory in the US.

Scientists warn we have a 20 metre sea level rise coming due to Global Warming

Scientists studying the geological record have determined that at slightly above current temperatures we are about 20 metres below what the sea level equilibrium should be. Sea levels are increasing and forecast to rise at least a metre this century (although there is a low probability they could be higher than this), the change in sea level will occur over several hundred or thousands of years.

Scientists looking at the Pliocene period from 2.7 to 3.2 million years ago, the last time temperatures were at a similar range of 2 degrees C above average, estimated peak sea level was 22 ± 10 m higher than modern levels (extreme likelihood). This rise in sea level would require the equivalent of the Greenland and West Antarctic ice sheets disintegrating, and some volume loss from the East Antarctic Ice Sheet. We are already seeing substantial mass loss from Greenland and West Antarctic Ice sheets.

Carnaby's Cockatoo suffers 37 per cent population decline in one year

Flocks of Carnaby's Black Cockatoo are iconic sights for the people of Perth, the Swan River Region and the forests of the South west. But comparing two population surveys in 2010 and 2011 showed a 37 percent decline in numbers across the Swan river region. That is a 37 per cent decline in one year.

According to Statistical modelling based on the 2011 Great Cocky Count the population of Carnaby’s cockatoos (Calyptorhynchus latirostris) in the Swan Region was between 5200 and 8600 birds. A year earlier it was estimated that the population was 8000 to 10,000.

Climate drying trend still evident despite wettest two year period on record

Back-to-back La Niña events has produced the wettest two year period on record for Australia according to the Bureau of Meteorology (BOM). The two year rainfall total for 2010-2011 of 1409 mm, eclipsed the old record of 1407 mm set during the big wet of 1973-1974. But underlying this wet record is a strong drying trend in the southeast and southwest of the continent with a consistent reduction in Autumn and winter rainfall and streamflow which are important for both agriculture and water storage.


Biodiversity a crucial climate change buffer for ecosystem and cultural diversity

A new multi-author scientific study says that preservation of plant biodiversity provides a crucial buffer to negative effects of climate change and desertification in drylands. Preventing ecosystem degredation in a warming world is significant with drylands particularly vulnerable to environmental changes and desertification. Dryland ecosystems cover 41% of the land surface of the Earth and support 38% of the human population.

Species biodiversity under threat from the velocity of climate change

Scientists have been able to calculate the velocity of climate change on land and ocean environments using temperature records to determine isotherms and their change in a fifty year period from 1960 to 2009. So how fast are climate envelopes moving? The general median answer is 27.3 km/decade on land, and 21.7 km/decade in the ocean. This equates to a speed needed to outrun climate change on land (2.7 kilometers per year) and in the oceans (2.2 kilometers per year). This rate of movement of thermal climate envelopes poses problems for species facing a high speed migration, or a difficult and abrupt adaptation or extinction.

Global Warming: Attenborough warns of ice shelf destruction in Antarctica

UK Naturalist and documentary maker David Attenborough has warned about the implications of climate change melting ice sheets in the polar regions but emphasised the changes under way in Antarctica "is likely to have the most dramatic effects of all".


Global warming in Antarctica: Glaciers accelerating, west Antarctic ice sheet losing mass

Scientists have been studying the climate change impact on ice shelfs and glaciers for some time in Antarctica, and particularly around the Antarctic Peninsula where there is substantial warming occurring increasing ice shelf melt and the speed and discharge of glaciers. The most recent studies predict a faster retreat for the Thwaites Glacier and that warm ocean currents are already speeding the melting of the Pine Island Glacier and Ice Shelf and Getz Ice Shelf. A NASA Icebridge flight detected a major new rift in the Pine Island ice shelf on October 14 - the start of the calving of a massive iceberg. A recent paper in Nature Geoscience discusses the Stability of the West Antarctic ice sheet in a warming world and the likelihood of collapse that would raise sea level by more than three metres over the course of several centuries or less.
