Cartoons and children’s books that show penguins and polar bears coexisting together perpetuate a widespread myth about their geographic distribution. Polar bears are found only in the far northern hemisphere. Penguins are found only in the southern hemisphere. Unlike the Arctic, with its bears, foxes, and humans, there are no land-based predators in Antarctica. This is why penguins and elephant seals are fearless of humans whereas ringed seals are not.

For example, since the early twentieth century the western United States has suffered a 73% loss in the coverage area of alpine tundra. H. F. Diaz et al., “Disappearing ‘Alpine Tundra’ Koppen Climatic Type in the Western United States,”

Under the high-end A2 emissions scenario, 12%-39% and 10%-48% of the Earth’s terrestrial surface is projected to experience novel and disappearing climates by 2100 A.D.; corresponding projections for the low-end B1 scenario are 4%-20% and 4%-20%.

There’s more to it than just temperature and rain. A key issue is the so-called CO
2
fertilization effect. Plants like CO
2
, so having more of it in the air tends to increase crop yields. Most agro-climate models build in a hefty benefit for this, based on early greenhouse experiments using enclosed chambers. This enables the models to offset a large share of the damages of summer heat and drought, owing to the anticipated fertilizing benefit from elevated CO
2
levels. However, more realistic experiments staged outdoors, using blowers over actual farm fields, show a much lower fertilization benefit. This suggests that the models may be seriously underestimating the negative impacts of climate change to world food production. S. P.

2
Concentrations,”

The 2007-09 International Polar Year (IPY,
www.ipy.org
) was an international science program focused on the Arctic and Antarctic that lasted from March 2007 to March 2009. More than two hundred projects, sixty countries, and thousands of scientists participated in IPY. It was actually the fourth such Polar Year, following earlier ones in 1882-83, 1932-33, and 1957-58.

2007 was the astonishing record year in which nearly 40% of the Arctic’s late-summer Arctic sea disappeared. See Chapter 5.

Canada asserts that the “Northwest Passage” (it actually contains several possible routes) constitutes a domestic waterway, whereas the United States, Russia, and European Union maintain it is an international strait. At present the tacit policy between the United States and Canada is to agree to disagree on this issue.
