Could Global Warming Make Life on Earth Better? 923
mikee805 writes "A lengthy article in Spiegel explores the possibility that global warming might make life on Earth better, not just for humans, but all species. The article argues that 'worst-case scenarios' are often the result of inaccurate simulations made in the 1980s. While climate change is a reality, as far as the article is concerned, some planning and forethought may mean that more benefits than drawbacks will result from higher temperatures. From the article:'The medical benefits of higher average temperatures have also been ignored. According to Richard Tol, an environmental economist, "warming temperatures will mean that in 2050 there will be about 40,000 fewer deaths in Germany attributable to cold-related illnesses like the flu." Another widespread fear about global warming -- that it will cause super-storms that could devastate towns and villages with unprecedented fury -- also appears to be unfounded. Current long-term simulations, at any rate, do not suggest that such a trend will in fact materialize.'"

Although arguing based on authority is something I don't usually do, but in the case of global warming most common people just display ignorance about the matter. That in itself is not a problem, but writing articles proclaiming truths which show signs that the guy didn't even bother to do basic research is bad. I wish people would try to inform themselves before trying to form the opinions of others.
Science is complex, deal with it. Naive, overly simplistic ideas set off my bullshit alarm, like in the case of "paranormal" stuff.

I don't know if you're right about the sun (though there is evidence to suggest you are), but you're certainly right to be skeptical about CO2 causing global warming. Worse is that the lack of balanced scientific debate on the topic, and the number of lemmings who blindingly need to point a finger without any actual evidence, is undermining the ability to observe and make rational opinions.
However, it's Slashdot. It's a populous opinion. Don't take it personal when the lemmings come and mod you down for, God forbid, positing something contrary to the convenience of their finger-pointing!

I have no doubts that life will adapt to global climate change, fewer corals but lots of algae and red tide in the new warm oceans.
I think maintaining the status quo of historical climates seems to have many economic benefits that should not be ignored. And major global climate change would likely shift most markets fast towards the red. The markets would be forced to adapt quickly, which they are not very good at doing without a lot of suffering by the people at the bottom. Perhaps this is the conservative in me talking.

Also, with respect to the warming is good for life argument, the Earth has most certainly been warmer, and likely more violent weather-wise. Our distinct problem is that we have virtually eliminated the possibility of more life spawning by killing its potential habitat and introducing toxic waste of various forms.
I wrote an article 15 years or so ago arguing that global warming wasn't the biggest issue, but rather that desertification and the elimination of biodiversity was. Whether we can live in a world without a functional ecology is going to be something we quickly find out. If it's warmer doesn't really matter, unless you are in a stressed area. My opinion is that a lot of people are going to perish, but as usual YMMV. As if they already are not perishing! It may simply be more permanent for many regions.
Predicting those regions is like predicting the weather!

Change is Bad (for us) (Score:2, Interesting)
I would make the argument that significant change in an ecosystem will usually be bad for the dominant species that have adapted to live in that ecosystem. Change can of course give opportunities to other species that have struggled to live in an ecosystem. The obvious examples are the past mass extinctions, especially the one that gave rise to the dinosaurs, as well as the one that destroyed the dinosaurs and gave rise to mammals.
Significant change destroys. It destroys existing systems. It plays havoc on most species. It creates starvation for species that have grown to need the existing systems that are being swept away. Of course, this allows new species to rise and fill the vacuum. Change is the prime driver of evolution. Evolution works at its fastest when there is mass death and destruction.
And today, we are the dominant species on the Earth. The agricultural systems that we rely on are built on our current climatic conditions. Farms are located in certain places that have the perfect combinations of good soil, and good weather. Too much rain, or too little, or rain at the wrong time can destroy crops. If the rain moves from an area with good soil to an area with bad soil, then this will reduce crop yields, even if our farmers follow the rain. Moving the water by canal or pipeline is an option, but it is expensive (how much did the Panama Canal cost to build?).
I can think of no better an example of the problems of climate change than the Australian drought. Australia has already lost 1% of its GDP due to drought conditions. And without significant rain in the coming weeks, the country faces draconian water restrictions: Brisbane is at stage 5 water restrictions right now, which effectively means flushing the toilet every 7 uses and keeping shower water in a bucket for later use. Agriculture along the Murray Darling River (the main agricultural river system) faces a complete cutoff of irrigation. That means the death of the many grape vines that form the basis for Australia's wine industry.
Here is a map [nasa.gov] that shows how rainfall patterns have changed. The interior (where no one lives) is receiving more rain. The coasts (where almost everyone lives) are receiving less rain. The rainfall patterns have changed, and the Australians are struggling to adapt to the new conditions.

* Because of over a century of adding carbon dioxide to the atmosphere, the average temperature in Earth is increasing.
* This has foreseeable negative impacts.
* The scariest impacts are from subtle effects that we can't even predict.
* Models say we are approaching a tipping point where the changes become self-sustaining and self-feeding.

Conservative talking points
* Global warming is not happening. It's a liberal myth.
* It's a normal cycle, not caused by man.
* It's pointless for us to try to slow global warming because India and China are putting much more carbon dioxide in the atmosphere than the United States is, and they won't stop.
* What's the big deal? It's only a few degrees change, and will make life better on Earth. Don't you like nicer weather?
* It's too late to stop the major effects of global warming. Better for the the government to encourage and subsidize business to adapt to and profit from the major changes that will inevitably occur.

Nobody, of course. The same does apply though about me dropping a stone to the ground - I can not say with absolute certainty that it will actually reach the ground. However I'm a lot more certain about this, than about global warming. So can we agree at least, that degrees of certainties (i.e. probabilities) do matter?
all we have are computer models and theories
I can write a model of the climate with a simple 10-line perl script, but it won't be very good. I would think the quality of the model is vital. All of science is just theory, but I trust it with my life each time I enter a plane, and each time I use my car. Even the methods used to evaluate the statics of the house I'm in are based on scientific theory, and not absolute certainty.
It is my belief that money, time, and energy are better spent in actively reducing air, ground, and water pollution than throwing money into global warming research.
I don't think that the money spent on climate _research_ is significant in comparison to what's needed to reduce pollution. In any case - that using the money to reduce polution would be beneficial is a belief with a very low degree of certainty. (Quite fairly you used "my belief" not "I'm 100% certain".) You base it on your private doubts about a theory which you (and me too, for sure) do not fully understand. Now if I build a house, I would listen to the engineer doing the statical calculations. Similarly, if I hired a professional in that field to check whether my house is still statically sound, I would listen to his advice if he concludes that it's not and make the required repairs.
I realize that there must be at least some people in the field who are not competent, so the chance that this engineer would be one of them is not zero. Nevertheless unless I'm able to do the calculations myself, I would go with the professional opinion. Now with global warming, the vast majority of experts agree. The probability that they are part of a huge conspiracy is not zero, but it has to be low considering the number of people who'd have to be involved. The risk of not taking their advice if they are not part of a huge conspiracy, is high. Given that we can not be 100% certain it seems sensible to err on the side of caution.

My personal opinion (without studying the matter) is that we probably don't have enough evidence to guess whether there were more or fewer species. (Well, except that clearly there were fewer, e.g., right after the asteroid hit. And right after whatever caused the Permian Catastrophe. Etc.) Most species never leave any discovered and recognized fossil record, and we don't know what percentage "most" means, just that it's large relative to 50%. (There may, of course, people who have reasons to believe some particular number is "about right", but I'm not one of them.)
Re:Yeah not sure it's caused by 'cold'. (Score:3, Interesting)
"Catching cold" is accurate. You lose 60-80% of body heat through your head in cold weather without a hat. Heating your body is a significant energy stress on your body, so if you are in a cold weather situation without a hat, your caloric requirements go way up. Running your immune system has energy requirements as well, but on a scale of priorities, preventing immediate death by freezing is higher than maintaining your immune system at 100%. So if you put a very heavy load on your body for heating, you lose efficiency in the immune system and because pathogens are very efficient customers, this can easily put you below the threshold where you are not catching all the shots that are fired at you.
At which point you catch a cold.
In the elderly this is seen most clearly because their heating system starts to wear out and becomes much less efficient. Which is why many elderly people complain of being hot or cold all the time, and why so many older people die from pneumonia from something simple like being caught in the rain on a chilly day. The cold wet clothes leech energy right out of their system and the immune system takes a big hit which allows sickness to take hold and then they don't have the strength to bounce back.

Health benefits? (Score:3, Interesting)
Even modest increases in temperatures can have non-linear effects in transmission of vector borne diseases. For example Mexico City, while in a latitude where Malaria is endemic, is free of it because its altitude makes it too cool for the Anopheles mosquito to establish itself; that is to say the range of the disease vector is limited by latitude and altitude. Once conditions at its 2240m elevation become inhabitable, the tenth most populous city in the world becomes vulnerable.
In the US,there have been serious outbreaks of Yellow Fever as far north as Boston. The 1793 Philadelphia epidemic killed 10% of the population and was only checked by cold weather in November. Philadelphia was an interesting case because it epidemic came in with slave trading ships; international trade is now a major transporter of disease vectors such as the asian tiger mosquito.
Infectious agents are now thought to play a role in both maintaining and disrupting ecological stability. New organisms who move into an already occupied are immunologically naive to pathogens present in the habitat, which forms a kind of natural defense. Likewise they may bring new pathogens in; the European settlement of the Americas would have gone differently were it not for smallpox.
The disruptions caused by both climate change and the human response to it are likely to spill a number of novel tropical infectious agents (such as Ebola) from their currently limited geographic ranges. International trade will transport them around the world. In particular vector borne diseases that have a capacity to establish themselves in wild animal populations have the potential to become endemic in temperate regions (as West Nile did, although WNV is relatively benign as such things go).
That's not to say global warming won't have some health benefits. But we can expect a number of novel diseases to emerge, many well known diseases to become more of a problem.
