1. What are a couple of examples of how
animals have changed because of climate
A: Insects are moving the time that they come out
of overwintering earlier. Birds are changing their
migration patterns. Polar bears are moving back
into the encroaching forest and mating with brown
bears to create hybrids. Plants are also changing
the time that they flower, fruit, etc. which
affects when food becomes available for animals.
2. What is some evidence that proves that
climate change is happening?
A: Glaciers are retreating (almost) all over the
world. Thermometers in weather stations are
measuring increasing average temperatures with
each passing decade.
Contrary to popular belief, year-to-year changes
in weather are NOT climate change. The variability
in weather from one year to the next are larger
than the change in climate from one year to the
3. Can people die because of too much carbon in
A: No. Carbon dioxide is not toxic to humans at
the levels that we are putting it into the
atmosphere (although volcanic eruptions can kill
humans with carbon dioxide!). What is dangerous to
humans is changes in the climate and, thus, the
weather. Life in the ocean may be a different
story, though, as carbon dioxide in water does
make the water more acid.
4. Where is climate change effecting in the world
the most? In your opinion, can climate change be
A: Climate change affects different areas
differently. In parts of the world that are cold,
it raises temperature. In parts of the world that
are warm, it changes rainfall patterns.
Climate change itself is a natural process and
cannot be stopped. We humans are making it
worse through our actions, however.
5. What year is climate change going to
A: Climate will continue to change for as long as
the sun continues to shine - about six billion
years. This is because the sun is a variable star
and changes in the power of the sun will change
climate on the planets that orbit it.
