Gore told the world in his Academy Award-winning movie (recently labeled “one-sided” and containing “scientific errors” by a British judge) to expect 20-foot sea-level rises over this century. He ignores the findings of his Nobel co-winners, the IPCC, who conclude that sea levels will rise between only a half-foot and two feet over this century, with their best expectation being about one foot. That’s similar to what the world experienced over the past 150 years.
Likewise, Gore agonizes over the accelerated melting of ice in Greenland and what it means for the planet, but overlooks the IPCC’s conclusion that, if sustained, the current rate of melting would add just three inches to the sea level rise by the end of the century. Gore also takes no notice of research showing that Greenland’s temperatures were higher in 1941 than they are today.
Gore also frets about the future of polar bears. He claims they are drowning as their icy habitat disappears. However, the only scientific study showing any such thing indicates that four polar bears drowned because of a storm.
The politician-turned-movie maker loses sleep over a predicted rise in heat-related deaths. There’s another side of the story that’s inconvenient to mention: rising temperatures will reduce the number of cold spells, which are a much bigger killer than heat. The best study shows that by 2050, heat will claim 400,000 more lives, but 1.8 million fewer will die because of cold. Indeed, according to the first complete survey of the economic effects of climate change for the world, global warming will actually save lives.
The IPCC has magnanimously declared that it would have been happy if Gore had received the Nobel Peace prize alone. I am glad that he did not, and that the IPCC’s work has rightfully been acknowledged.
Gore has helped the world to worry. Unfortunately, our attention is diverted from where it matters. Climate change is not the only problem facing the globe. Our blinkered focus on it – to the detriment of other planetary challenges – will only be heightened by the attention generated by Gore’s Nobel Peace Prize.
Gore concentrates above all else on his call for world leaders to cut CO2 emissions, yet there are other policies that would do much more for the planet. Over the coming century, developing nations will be increasingly dependent on food imports from developed countries. This is not primarily a result of global warming, but a consequence of more people and less arable land in the developing world.
The number of hungry people depends much less on climate than on demographics and income. Extremely expensive cuts in carbon emissions could mean more malnourished people. If our goal is to fight malnutrition, policies like getting nutrients to those who need them are 5,000 times more effective at saving lives than spending billions of dollars cutting carbon emissions.
Likewise, global warming will probably slightly increase malaria, but CO2 reductions will be far less effective at fighting this disease than mosquito nets and medication, which can cheaply save 850,000 lives every year. By contrast, the expensive Kyoto Protocol will prevent just 1,400 deaths from malaria each year.
While we worry about the far-off effects of climate change, we do nothing to deal with issues facing the planet today. This year, malnutrition will kill almost four million people. Three million lives will be lost to HIV/AIDS. Two and a half million people will die because of indoor and outdoor air pollution. A lack of micronutrients and clean drinking water will claim two million lives each.
With attention and money in scarce supply, what matters is that we first tackle the problems with the best solutions, doing the most good throughout the century. If we focus on solving today’s problems, we will leave communities strengthened, economies more vibrant, and infrastructures more robust. This will enable these societies to deal much better with future problems – including global warming. Committing to massive cuts in carbon emissions will leave future generations poorer and less able to adapt to challenges.
Gore has an unshakable faith that climate change is the biggest challenge facing the world. To be fair, he deserves some form of recognition for his resolute passion. However, the contrast between this year’s Nobel winners could not be sharper. The IPCC engages in meticulous research where facts rule over everything else. Gore has a very different approach.
