Global Warming is a hoax

with the Co2 ppm it was 7000ppm in the Cambrian but it should be decreasing not increasing http://globalwarming.berrens.nl... "Even if greenhouse emissions stopped overnight the concentrations already in the atmosphere would still mean a global rise of between 0.5 and 1C. A shift of a single degree is barely perceptible to human skin, but it"s not human skin we"re talking about. It"s the planet; and an average increase of one degree across its entire surface means huge changes in climatic extremes. Six thousand years ago, when the world was one degree warmer than it is now, the American agricultural heartland around Nebraska was desert. It suffered a short reprise during the dust- bowl years of the 1930s, when the topsoil blew away and hundreds of thousands of refugees trailed through the dust to an uncertain welcome further west. The effect of one-degree warming, therefore, requires no great feat of imagination. "The western United States once again could suffer perennial droughts, far worse than the 1930s. Deserts will reappear particularly in Nebraska, but also in eastern Montana, Wyoming and Arizona, northern Texas and Oklahoma. As dust and sandstorms turn day into night across thousands of miles of former prairie, farmsteads, roads and even entire towns will be engulfed by sand." What"s bad for America will be worse for poorer countries closer to the equator. It has beencalculated that a one-degree increase would eliminate fresh water from a third of the world"s land surface by 2100. Again we have seen what this means. There was an incident in the summer of 2005: One tributary fell so low that miles of exposed riverbank dried out into sand dunes, with winds whipping up thick sandstorms. As desperate villagers looked out onto baking mud instead of flowing water, the army was drafted in to ferry precious drinking water up the river " by helicopter, since most of the river was too low to be navigable by boat. The river in question was not some small, insignificant trickle in Sussex. It was the Amazon. While tropical lands teeter on the brink, the Arctic already may have passed the point of no return. Warming near the pole is much faster than the global average, with the result that Arctic icecaps and glaciers have lost 400 cubic kilometres of ice in 40 years. Permafrost " ground that has lain frozen for thousands of years " is dissolving into mud and lakes, destabilising whole areas as the ground collapses beneath buildings, roads and pipelines. As polar bears and Inuits are being pushed off the top of the planet, previous predictions are starting to look optimistic. Earlier snowmelt means more summer heat goes into the air and ground rather than into melting snow, raising temperatures in a positive feedback effect. More dark shrubs and forest on formerly bleak tundra means still more heat is absorbed by vegetation. Out at sea the pace is even faster. Whilst snow-covered ice reflects more than 80% of the sun"s heat, the darker ocean absorbs up to 95% of solar radiation. Once sea ice begins to melt, in other words, the process becomes self-reinforcing. More ocean surface is revealed, absorbing solar heat, raising temperatures and making it unlikelier that ice will re-form next winter. The disappearance of 720,000 square kilometres of supposedly permanent ice in a single year testifies to the rapidity of planetary change. If you have ever wondered what it will feel like when the Earth crosses a tipping point, savour the moment." every 1 degree gained at the equator is 12 degrees gained at the poles "the end of the world is nigh. A three-degree increase in global temperature " possible as early as 2050 " would throw the carbon cycle into reverse. Instead of absorbing carbon dioxide, vegetation and soils start to release it. So much carbon pours into the atmosphere that it pumps up atmospheric concentrations by 250 parts per million by 2100, boosting global warming by another 1.5C. In other words, the Hadley team had discovered that carbon-cycle feedbacks could tip the planet into runaway global warming by the middle of this century " much earlier than anyone had expected. " we may be only 3.5% of the problem with our output but our output is also making nature output more by 2100 north America will have the same water problem as Africa war will break out for the last bits of fresh water with the water rising they measure the water level at the equator and water flows from the equator to the poles and water is rising 7m there. Rome is in danger of flooding. http://www.rollingstone.com... just plain terrifying
