Climate change conjures images of long, hot summers, melting ice caps and stranded polar bears. But as the weather gets stranger, so too does its effects on the environment, sometimes in the oddest of ways. How well do you know the signs of change?

Sea levels rose by roughly how many inches in the 20th century?









Warmer temperatures can have a peculiar effect on cold-blooded animals. Scientists have observed that an increase in temperatures from climate change has caused some fish, amphibians, and reptiles to:

Grow in size


Shrink in size


Eat more


Spontaneously combust


Shorter winters have had a negative impact on winter sports industries in some areas. To highlight the change, some clever winter athletes organized a:

Snowless ski race


Indoor bobsled competition


Artificial snowball fight

Weave elaborate, dense cocoons of webs in trees above the stagnant water


Cling desperately to floating pieces of debris


Migrate en masse to neighboring Afghanistan

What weather-related event forced a nuclear plant in Connecticut to power down in the summer?

Lightning from a major thunderstorm threatened to damage the nuclear reactor


High temperatures caused the plant’s source of cooling water to overheat


Massive floods prevented workers from accessing critical parts of the plant


High winds carried toxic gas emissions into nearby populated areas


As water temperatures rise, pink salmon have begun spawning earlier than previously recorded. Scientists have linked this change in behavior to:



A change the salmon's diet


A change in the salmon's genes


A change in tidal patterns


The rate at which the Alps are growing is increasing. Name one reason why.

Rising global temperatures heat the earth’s crust, causing it to expand upward.


Increased levels of carbon dioxide in the earth’s atmosphere promotes healthy mountain growth.


Unusually heavy precipitation has increased the size of glaciers, making the mountains appear taller than they are.


The weight of glaciers dissipate as they melt, allowing the mountains to rise more quickly.


In the summer of 2012, a plane departing Reagan National Airport in Washington was delayed for what peculiar reason?

Baseball bats

The American Magnolia Festival


In the next 100 years, scientists predict global warming may do what to the deep waters in the Atlantic Ocean?

The new, shorter sea routes allow for easier trade between Europe and Asia, according to the Guardian.

Volatile weather kills off mosquitoes and other pests
