What Global Warming?.

[Champa]

Fact: All history reveals that time after time this planet of ours has experienced periods of warming and periods of cooling. A century of slight global warming, about half a degree, ended in 1998.
Fact: In this century a global cooling has set in. In 2008 most of the northern hemisphere, except for Western Europe, is coming out of what most scientists say has been the harshest winter in decades.
Malta, Israel, China and India’s New Delhi have been subjected to record low temperatures. In Afghanistan, more than 900 people and 316,000 head of cattle died as a result of bitter cold weather according to Reuters.
In a letter to U.N. Secretary General Ban Ki Moon 13 top scientists including one Nobel Prize winner, pointed to the fact that while CO2 levels have continued to rise, global temperatures have fallen, dramatically contradicting the claim that CO2 levels cause global warming. They wrote that the UN Climate change Panel “must be called to account and cease its deceptive practices - Policies based on False science must be ended.”

What's this? A Ron Paul Republican website hates liberals and doubts man made climate change? NEVER!

Regardless, let's push on through the article, shall we?

No, not true. This is a repeated mistake by deniers and people on Politics.ie. 1998 was a massive spike, most likely caused by freak weather events. While it is (as far as I can tell) the warmest year on record, this is not to say that global temperatures have been going down since. In fact, the upwards trend continues. Take a gander at this graph:


You can see where 1998 spikes up, but you can also see a gradual trend upwards, which continues.

Regional variations aren't, in themselves, of global temperature. If it's colder than usual in Arklow, that doesn't mean that the Earth isn't warming, since an overall increase in global temperature would have various effects on a complex weather system. Once again, the key things to watch are global climate trends. You can watch them at NASA, if you'd like. They show an upwards trend, as predicted.

They're wrong, and they base their letter on the idea that warming isn't happening, which is wrong.

The differences in local climates is very difficult to explain and model. Just because it is colder in some parts does noit mean on average that it is colder everywhere.

In a way the main effect is not actually the amount of warming but rather the redistribution of heat.
If we consider earth with no greenhouse effect would be ~35C colder and consider that the increases (currently) in temperature constitute no more than one degree, there is very little change in overall temperature. However the heat is being redistributed or moved. As the ice caps melt for example the liquid water or vapour moves causing cloud or decrease in salanity etc. This affects the climate and creates new local hot and cold spots or periods.

The ultimate (and unlikely) scenario for this is assuming that the ocean currents fail; the heat of the earth will accumulate at the central lattitudes (equator) as heat is no longer beong moved from here and the northern latitudes will freeze. So ultimately you could in theory end up with a larger area of ice but you will have a smaller habitable zone (as the equatorial lattitudes will bake).

Local veriations do not really tell much.

Indeed. One can imagine the frog saying "hey, it's a bit cooler over here - everything is going to be OK!".

Why do we need yet another thread on this? Why Champa, why? What is wrong with the other 42 threads on it? Seriously?

I wonder, do insurance companies who are dealing year-on-year with accelerating payouts of claims for weather-related damage believe in anthropogenic climate change?

It certainly looks like it.

Another example of an absolute nutter who says 98 was the warmest but yet it is getting warmer each year since.

I thought Einstein was dead

Are you going to dig him up as well?
