Human activities, including the use of fossil fuels, have contributed to global warming and the rise in sea levels. Both of these environmental changes are
threatening ecosystems and human communities worldwide. How could
scientists best cooperate to use scientific research to mitigate this problem?
A. They could look at trends in climate change to predict regions of
concern.
B. They could set regulations in their own countries to protect local
resources.
C. They could make personal choices that help reduce their carbon
footprints.
D. They could study climate change on other planets to predict its
effects on Earth.
