How does extreme weather patterns relate to global warming?

Question

Answer 1

A meteorologist explained it to me this way.

Extreme weather events are generated by the temperature difference between the equator and the poles. Since the poles heat up and cool down faster than the equator, a warmer climate will have fewer, less intense extreme weather events that a colder climate.

I realise this exactly contradicts the propaganda of the mass media, Al Gore and the political activists, but it is the opinion of a meteorologist with many years experience working in the Arctic. Which do you think is more reliable?

Answer 2

in Tabasco recently,super evaporation of a very hot sun on the forests.and seas caused freak rainfalls that made over a million people homeless overnight with water coming up to their roofs.

This was ofcourse NOT covered in North American Media

Why not ????

also hotter ground temperatures cause more frequent tornadoes and twisters  

Different and hotter ground temperatures have many interrelated effects on local weather patterns

And man is responsible for a lot of change as well,with fires gone out of control ,deforestation and subsequent desertification ,as is happening in Northern china

Answer 3

This was on ABC the other night. Apparently,the White House 'believes' Al Gore!  Check it out!

Answer 4

Global Warming adds energy to the Earth's biosphere.  Energy drives the water cycle.  The more energy there is the faster the water cycle is driven and the more extreme the weather patterns become.

Each one degree rise in the temperature of the world's oceans is the equivalent to 1.4 BILLION one Megaton atom bombs; that is a lot of energy.  It shouldn't be surprising that the result is more extreme weather.

Answer 5

Pretty simple.  Heat is the fuel of weather systems.  More heat, more extreme weather systems.

The fact that we've reduced toxic pollution has nothing to do with the fact that we're releasing way more CO2, which is not controlled by the systems that control toxic pollution.

And forget Al Gore, the mass media, and political activists.  EVERY major scientific organization has issued an official statement that global warming is real, and mostly caused by us.  The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.  They're a little more reliable than one meteorologist.

Answer 6

Clearly, extreme weather events have long been a concern of many climate scientists. No one can honestly deny that.

As you put more energy into our climate system (which is exactly what global warming entails) there will be changes to how it reacts.  And an increase in extreme weather events are one of the long predicted consequences.

More energy retained in our atmosphere means more heat.  More heat means more evaporation over the water and more drought in dry regions.  More evaporation means more precipitation in some regions. etc.

The latest (released yesterday) US government report on climate clearly states that an increase in extreme weather events is to be expected:

http://www.usgcrp.gov/usgcrp/default.php

"The increase in heavy precipitation events is associated with an increase in water vapor, and the latter has been attributed to human-induced warming."

"In the future, with continued global warming, heat waves and heavy downpours are very likely to further increase in frequency and intensity. ... The strongest cold season storms are likely to become more frequent, with stronger winds and more extreme wave heights."

Answer 7

They don't.  Can someone explain these articles?

"Malaysia is to try[ing] to generate rain using Russian equipment, in an attempt to clear the haze which has covered parts of south-east Asia for the past two months.

The Russian machinery has still to be tested, but the Malaysian authorities say it creates high winds, which then produce clouds and rainfall. They say they're confident the artificial cyclones won't damage property or the environment."

http://www.thewatcher.co.uk/weird/news.h...

...and these that followed?

"They say the rain is also putting out fires on the islands of Borneo and Sumatra which caused the smog.

The fires, mainly started by farmers clearing land for plantation, led to a haze which covered large areas of south-east Asia, and prompted warnings of serious damage to the environment and to people's health.  Officials in Singapore say they believe the haze has also cleared over their country."

The can also dry up clouds and create artificial drought conditions!

And they must think we're really, really stupid...

"...the air pollution delays the onset of precipitation, so that the intense storm clouds can build higher and larger before they start precipitating and subsequently dissipating. Therefore, these larger and more intense thunderstorm clouds produce eventually heavier rainfall on the city and the downwind areas. First is the unpolluted, then the polluted case."

Ironically, we're producing less pollution today than before (with cleaner fuels, catalytic converters, etc.), yet somehow we're affecting the climate more than before.  It doesn't make sense.
