How Extreme Weather affects by global warming (Climate change)

How Extreme Weather affects by global warming (Climate change) ?

There is currently a massive storm churning over the Atlantic that spans the entire ocean basin, stretching all the way from Canada to Europe, and from Greenland to the Caribbean.

It's the same weather system that brought a massive spring blizzard to much of the United States and Canada earlier this week (on Tuesday (March 26), 44 of 50 states had some snow on the ground), and which has now ballooned in size, according to Jason Samenow, chief meteorologist with the Washington Post's Capital Weather Gang.

Robert Oszajca, lead forecaster for the National Weather Service's Ocean Prediction Center, explained that the storm got this big by merging with several low-pressure systems that were hanging out over the Atlantic Ocean. The merging weather systems gave it more power, which was accentuated by a gradient between warm moisture from the southeast, delivered by the Gulf Stream, and frigid air from the north. This intensified the storm, causing it to spin, elongate and grow in size, Oszajca told OurAmazingPlanet.

Normally, the system would have drifted into Europe several days ago. However, a high-pressure system over Greenland blocked the low-pressure system's advance, which allowed it to strengthen further, fed by cold air from the north. This created winds (which move from high pressure to low pressure) up to 75 mph (120 km/h), equivalent to a Category 1 hurricane, Oszajca said. 

"We're impressed with the size of this storm," he said. Nevertheless, storms this big form about once or twice every winter.

The storm, which looks like a large comma whose tail stretches into the Caribbean, ranges from Eastern Canada all the way to Spain and north to Greenland. It has created waves up to 42 feet (13 meters) high, Oszajca said.

The storm has already begun to weaken, however, as the high-pressure "blocking" system to the north has eased. Oszajca said the central low-pressure system that has powered the storm will soon break up into several separate centers, and the storm will fragment before hitting Portugal in about four days. The storm isn't expected to be very intense by the time it reaches Europe.

man-caused global warming a hoax

Plant scientist, I am concerned that Idaho and most states are planning to limit and reduce Carbon Dioxide (CO2) emissions. This is being done to supposedly reduce global warming. The states are adopting the 1997 Kyoto Climate Treaty which the U.S. Senate rejected 95-0 because it would destroy our economy while exempting developing nations like China which do not control pollution.

CO2 is not a pollutant and is not causing global warming. CO2 is necessary for life on the planet, as plants utilize CO2 to produce the oxygen we breathe and the food we eat! Global warming now and cooling of the 40’s to mid-seventies is caused by solar activity. We have an active sun now! The earth has been warming for 300 years with most of the increase prior to increased CO2 levels.

Also, 279 research project reports have shown that increasing CO2 increases crop production. Higher levels of CO2 is creating a lush environment for plants and animals and will improve the health (more oxygen), longevity and prosperity of all people.

Over 20,000 U.S. scientists have signed a petition opposing man-caused global warming and the benefits of increased CO2 levels, but the mass media totally ignore them. John Coleman, founder of The Weather Channel, stated that man-caused global warming is the biggest hoax ever perpetrated on mankind.

The biased United Nation’s panel and Al Gore are promoting a lie to scare us into a U.N. global government. The bottom line is that we need to produce more energy, not less. We have a 300 year U.S. supply of crude oil and unlimited nuclear power. There is no scientific reason to limit CO2 production because it is not causing global warming

Effects of Global Warming

The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move.

Some impacts from increasing temperatures are already happening.

•Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
•Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
•Sea level rise became faster over the last century.
•Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
•Precipitation (rain and snowfall) has increased across the globe, on average.
•Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
.Other effects could happen later this century, if warming continues.

•Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).
•Hurricanes and other storms are likely to become stronger.
•Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
•Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
•Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
•Some diseases will spread, such as malaria carried by mosquitoes.
•Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier. Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay. He fears that if sea ice disappears, the polar bears will as well.
