(Via David Boaz):
This year's Nobel peace prize justly rewards the thousands of scientists of the United Nations climate change panel (the IPCC). These scientists are engaged in excellent, painstaking work that establishes exactly what the world should expect from climate change.
The other award winner, former US vice-president Al Gore, has spent much more time telling us what to fear. While the IPCC's estimates and conclusions are grounded in careful study, Gore doesn't seem to be similarly restrained.
Gore concentrates above all else on his call for world leaders to cut CO2 emissions, yet other policies would do much more for the planet. Over the coming century, developing nations will be increasingly dependent on food imports from developed countries, not primarily as a result of global warming, but because 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.
With attention and money in scarce supply, we should first tackle the problems with the best solutions, thereby doing the most good throughout the century. Focusing on solving today's problems will leave communities strengthened, economies more vibrant, and infrastructures more robust. This will enable us to deal much better with future problems - including global warming - whereas committing to massive cuts in carbon emissions will leave future generations poorer and less able to adapt to challenges.
To be fair, Gore 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.
