Climatic records put together with long-term
records of flowering and nesting times show clear warming
trends.
Increased CO2 levels cause poison ivy and
other weeds to grow “taller, lusher, and more resilient.”
Rapid temperature changes affect the
seasons, causing variations in season length effecting
feeding periods for young birds and availability of worms or
insects for food.
Something to think about:
Polar bears in the Hudson Bay area of Canada
are losing weight and getting less fit because the ice breaks up
2 weeks earlier in spring, robbing them of 2 weeks’ hunting.
