Guy Callendar is proof that you don’t need a Ph.D. to make scientific models! Eighty years ago, he created a coherent model of climate change — that people were creating enough carbon dioxide to raise the world’s average temperature.

In Britain, climate scientists have determined that town planners in big cities can increase their wealth by planting more trees. Trees can increase property value, while improving a city’s overall health.

Albinism is an inherited condition present not only in humans, but in plants and animals as well. Among squirrels, there is a difference between an albino squirrel and a white squirrel, the most obvious being eye color – the former has red eyes, while the latter doesn’t. However, the white squirrel — a color variant of the eastern gray squirrel (Sciurus carolinensis) — gets help from us humans to survive in nature.

What should birds do to escape rising temperatures in the Pacific Northwest? New research shows that heading to old-growth forests could be the solution.

To protect or not to protect street trees… The results of a new study published in Ecological Engineering show that street trees in New York City protected from pedestrians by tree guards absorb more runoff water than trees with unprotected pits. These findings can help urban areas develop “green infrastructure” to drain excess water.

Wildlife advocates claim the reintroduction of the extinct eastern cougar to New York State, possibly to the Adirondack Mountains, will restore balance to the ecosystem and improve human lives. Benefits of this action would include reducing the prey population and slowing the spread of Lyme disease.
