Forests may cause global warming
Trees are designed to soak up massive amounts of energy from the sun. Much of this, he argues, is gradually released in the form of heat, especially in dark evergreen forests in the north, but also in temperate forests of maple, poplar and beech. Unlike tropical forests, Canadian forests don't release much cooling moisture. . . .

"I like forests. They provide good habitats for plants and animals," he said. . . .
