Millions of monarch butterflies (Danaus plexippus) roost on the Chincua Mountain near Angangueo, Mexico. This is one of five wintering roosts for monarchs, where the cool mountain climate slows their metabolism enough for them to overwinter before migrating back northward in the spring. Logging threatens this spectacle–Already one of the five sites is no longer used by the butterflies due to the forest being cleared.

Scientists at the Toolik Research Center study the effects of global warming on the tundra. If the permafrost melts, the amount of carbon released into the air could make man-madeemissions look trivial, the scientists said. Shown are botanists studying a thermokarst in which the permafrost has melted away
