Effects of Global Warming

Global Warming effects
Green house gases stay can stay in the atmosphere for an amount of years ranging from decades to hundreds and thousands of years. No matter what we do, global warming is going to have some effect on Earth. Here are the 5 deadliest effects of global warming.
5. Spread of diseaseAs northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. Indeed some scientists believe that in some countries thanks to global warming, malaria has not been fully eradicated.
4. Warmer waters and more hurricanesAs the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. We saw in this in 2004 and 2005.
3. Increased probability and intensity of droughts and heat wavesAlthough some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate Change, global warming will exacerbate the conditions and could lead to conflicts and war.
2. Economic consequencesMost of the effects of anthropogenic global warming won’t be good. And these effects spell one thing for the countries of the world: economic consequences. Hurricanes cause do billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.
1. Polar ice caps meltingThe ice caps melting is a four-pronged danger.
First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise.
Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English - make it less salty. The desalinization of the gulf current will “screw up” ocean currents, which regulate temperatures. The stream shutdown or irregularity would cool the area around north-east America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area!
Third, temperature rises and changing landscapes in the artic circle will endanger several species of animals. Only the most adaptable will survive.
Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect sunlight, much of which is relected back into space, further cooling Earth. If the ice caps melt, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.
So what is the solution? Are we just being negative? Are there any positive effects of global warming? What about all the stupid global warming solutions. We welcome your thoughts.

Global Warming May Stop

Global warming will stop until at least 2015 because of natural variations in the climate, scientists have said.
Have your say: Do you believe in global warming?
Arctic ice melting 'faster than predicted'
Weather Channel boss calls global warming 'the greatest scam in history'
Researchers studying long-term changes in sea temperatures said they now expect a "lull" for up to a decade while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions.

Melting icebergs: The study predicts the IPCC's 0.3ºC temperature rise for the next decade may not happen
The average temperature of the sea around Europe and North America is expected to cool slightly over the decade while the tropical Pacific remains unchanged.
This would mean that the 0.3°C global average temperature rise which has been predicted for the next decade by the UN's Intergovernmental Panel on Climate Change may not happen, according to the paper published in the scientific journal Nature.
However, the effect of rising fossil fuel emissions will mean that warming will accelerate again after 2015 when natural trends in the oceans veer back towards warming, according to the computer model.
Noel Keenlyside of the Leibniz Institute of Marine Sciences, Kiel, Germany, said: "The IPCC would predict a 0.3°C warming over the next decade. Our prediction is that there will be no warming until 2015 but it will pick up after that."

He stressed that the results were just the initial findings from a new computer model of how the oceans behave over decades and it would be wholly misleading to infer that global warming, in the sense of the enhanced greenhouse effect from increased carbon emissions, had gone away.
The IPCC currently does not include in its models actual records of such events as the strength of the Gulf Stream and the El Nino cyclical warming event in the Pacific, which are known to have been behind the warmest year ever recorded in 1998.
Today's paper in Nature tries to simulate the variability of these events and longer cycles, such as the giant ocean "conveyor belt" known as the meridional overturning circulation (MOC), which brings warm water north into the North East Atlantic.
This has a 70 to 80-year cycle and when the circulation is strong, it creates warmer temperatures in Europe. When it is weak, as it will be over the next decade, temperatures fall. Scientists think that variations of this kind could partly explain the cooling of global average temperatures between the 1940s and 1970s after which temperatures rose again

Global Warming Predictions

Climate models attempt to predict the future. They work like this. Climatologists must first consider umpteen climate variables which play a part in affecting long-term weather patterns (eg variations in the concentration of greenhouse gases in the atmosphere, the cloud cover, humidity, how heat energy from the ocean interacts with the atmosphere). These parameters are then fed into a computer model of the atmosphere, built from standard physics principles.
When all the parameters have been entered, the model begins number-crunching, letting every variable interact and 'stew'. The model typically calculates the outcome for a 30-minute interval. But obviously, predicting the climate 30 minutes from now is pretty pointless, so the computer crunches for 30-minute intervals over a longer simulated period of time, typically 30 years. It advances the new data from the last 30-minute run into the next 30-minute run, and so on. Hence the need for powerful computers – a 30-year time period means over half a million 30-minute solutions for every location on the planet! At the end of the simulation, climatologists can analyse what effect occurred over specific areas, known as grids.
