BBC: What Happened to Global Warming?

What happened to global warming?

By Paul Hudson
Climate correspondent, BBC News

This headline may come as a bit of a surprise, so too might that fact that the warmest year recorded globally was not in 2008 or 2007, but in 1998.

But it is true. For the last 11 years we have not observed any increase in global temperatures.

And our climate models did not forecast it, even though man-made carbon dioxide, the gas thought to be responsible for warming our planet, has continued to rise.

So what on Earth is going on?

Climate change sceptics, who passionately and consistently argue that man's influence on our climate is overstated, say they saw it coming.

They argue that there are natural cycles, over which we have no control, that dictate how warm the planet is. But what is the evidence for this?

During the last few decades of the 20th Century, our planet did warm quickly.

Sceptics argue that the warming we observed was down to the energy from the Sun increasing. After all 98% of the Earth's warmth comes from the Sun.

But research conducted two years ago, and published by the Royal Society, seemed to rule out solar influences.

The scientists' main approach was simple: to look at solar output and cosmic ray intensity over the last 30-40 years, and compare those trends with the graph for global average surface temperature.

And the results were clear. "Warming in the last 20 to 40 years can't have been caused by solar activity," said Dr Piers Forster from Leeds University, a leading contributor to this year's Intergovernmental Panel on Climate Change (IPCC).

But one solar scientist Piers Corbyn from Weatheraction, a company specialising in long range weather forecasting, disagrees.

He claims that solar charged particles impact us far more than is currently accepted, so much so he says that they are almost entirely responsible for what happens to global temperatures.

He is so excited by what he has discovered that he plans to tell the international scientific community at a conference in London at the end of the month.

If proved correct, this could revolutionise the whole subject.

Ocean cycles

What is really interesting at the moment is what is happening to our oceans. They are the Earth's great heat stores.
“ In the last few years [the Pacific Ocean] has been losing its warmth and has recently started to cool down ”

According to research conducted by Professor Don Easterbrook from Western Washington University last November, the oceans and global temperatures are correlated.

The oceans, he says, have a cycle in which they warm and cool cyclically. The most important one is the Pacific decadal oscillation (PDO).

For much of the 1980s and 1990s, it was in a positive cycle, that means warmer than average. And observations have revealed that global temperatures were warm too.

But in the last few years it has been losing its warmth and has recently started to cool down.

These cycles in the past have lasted for nearly 30 years.

So could global temperatures follow? The global cooling from 1945 to 1977 coincided with one of these cold Pacific cycles.

Professor Easterbrook says: "The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling."

So what does it all mean? Climate change sceptics argue that this is evidence that they have been right all along.

They say there are so many other natural causes for warming and cooling, that even if man is warming the planet, it is a small part compared with nature.

But those scientists who are equally passionate about man's influence on global warming argue that their science is solid.

The UK Met Office's Hadley Centre, responsible for future climate predictions, says it incorporates solar variation and ocean cycles into its climate models, and that they are nothing new.

In fact, the centre says they are just two of the whole host of known factors that influence global temperatures - all of which are accounted for by its models.

In addition, say Met Office scientists, temperatures have never increased in a straight line, and there will always be periods of slower warming, or even temporary cooling.

What is crucial, they say, is the long-term trend in global temperatures. And that, according to the Met office data, is clearly up.

To confuse the issue even further, last month Mojib Latif, a member of the IPCC (Intergovernmental Panel on Climate Change) says that we may indeed be in a period of cooling worldwide temperatures that could last another 10-20 years.

Professor Latif is based at the Leibniz Institute of Marine Sciences at Kiel University in Germany and is one of the world's top climate modellers.

But he makes it clear that he has not become a sceptic; he believes that this cooling will be temporary, before the overwhelming force of man-made global warming reasserts itself.

So what can we expect in the next few years?

Both sides have very different forecasts. The Met Office says that warming is set to resume quickly and strongly.

It predicts that from 2010 to 2015 at least half the years will be hotter than the current hottest year on record (1998).

Sceptics disagree. They insist it is unlikely that temperatures will reach the dizzy heights of 1998 until 2030 at the earliest. It is possible, they say, that because of ocean and solar cycles a period of global cooling is more likely.

One thing is for sure. It seems the debate about what is causing global warming is far from over. Indeed some would say it is hotting up.

I buy hundreds of gallons of gasoline at once in large (contraband) tanks that I bought in Latin America... I then burn that gasoline on my front driveway for heat, because all that energy my electric heating system uses is awful for the environment.

i bought a big laser so i could blast holes in the ozone layer myself

(the laser runs on kittens and produces 500 tons of methane every second.)

Se7en, if nothing else, I'll have the noise police (ie. me) onto you for idling your car for no good reason. I'd say that the violence situation in your street is about to heat up.

I hope you are also having your 10,000 watts hi-fi stereo amped up with cheap techno. Otherwise you could as well stop the engine.

cognitive dissonance knows know bounds. that's why i've now jacked my car up on cinder blocks and am burning the tires to protest kieran's insistence that pollution is harmless. i won't rest until he is coughing blood.

This is pretty funny:

YouTube - Daring to Question Al Gore

Some counter propaganda:

YouTube - NOT EVIL JUST WRONG

It's nice to see some competition of ideas out there instead of blind hypocritical monism. The green movement isn't trying to stop idling of cars but are trying to change the economy without a cheap green alternative to gas, coal and nuclear. They hope that when the hardship happens a new alternative will spring up. Until then we are just supposed to eat the taxes. It's convenient to attack coal companies and energy companies but they are just supplying a demand and in turn they will pass their costs onto us until this new miraculous technology appears.

I really want to see Prince Charles and Al Gore downsize their lifestyles first before they tell the middle class to cut back. People are struggling to pay their bills and that's if they have a job.

Competition of ideas is fine provided the best idea wins. The reality is there are only a certain number of people with the qualifications and expertise to adjudge whether anthropogenic climate change is happening or not - and the vast, overwhelming majority of those agree that it is. In the internet age what we now seem to have is the democratisation of 'ideas' to the extent that any idiot mouthing off on a blog is to be given the same credence as people who actually devote their life careers to the subject.

The UK's most prominent climate change sceptical journalist, Christopher Booker, for example, has no scientific qualifications whatever. Bjorn Lomberg, a prominent global warming sceptic, is an economist, not a scientist. Of course, Gore is not a scientist either, but he has better scientific backing than the other side of the debate.

Some of the loudest voices in the climate change sceptics' camp seem to have no scientific expertise - and granted, to some extent, this also applies to some of the loud voices on the other side, e.g., George Monbiot's unnecessary personalised attacks on people who disagree with him, e.g. his campaign to discredit David Bellamy. In turning his blog into a hitpiece on a elderly botanist, Monbiot, even though he might have science on his side, ends up discrediting himself and the movement he supports.

There are peer reviewed journals on both sides so I don't think the competition is over. If Richard Lindzen and Roy Spencer are destroyed by the evidence then we could see something of a scientific consensus. As of yet they are publishing more works showing that the IPCC is 6 times off the mark and they still don't have a marker for longer term anthropogenic warming. How much is natural and how much is us? This has not been definitively proved yet.

We even have geologists and climatologists weighing in now talking about C02 as being green :

YouTube - Leighton Steward Interviewed on the Benefits of CO2 (FOX Business News 10-09-09)

CO2 Science

Then you get the economics and statistics side of it (how do we interpret data without statistics?) which is just as important. If there is no replacement for fossil fuels then are the Al Gore types going to admit that our standard of living has to decrease? This is a moral argument. Can we tolerate warming while we get wealthier and adjust (including the 3rd world) or are we going to have to shrink the middle class and tell the 3rd world to stop developing and fill Al Gore's green businesses with license money? Having Prince Charles talking about the environment just adds to the suspicion people have that Marxists and environmentalists have allied to create another middle ages where the important people who administer the bureaucracy have the high standard of the living and the rest get the shaft. So even if the Al Gore types are right we can't just say "to hell with wealth" and not expect hardship for people. Maybe if we have some cool new Star Trek gadget that can create energy without CO2 emissions then we can quickly move in that direction and still expand our standard of living. Until I'm as wealthy as Al Gore (in my dreams) I will continue to expand my standard of living with no guilt.
