When it comes to climate change, the questions people have are limitless.
Some of these questions are scientific, some are economic, some are
political, and some are moral. Some questions have answers today,
and some won’t be answerable for decades.
In this column, the Earth Observatory offer answers to some of the
questions people ask us about the science of global warming and climate
change. We have also included some questions and answers about climate
science topics that people often misunderstand. All posts are written or
reviewed by Earth and climate scientists.
We choose questions based on several factors, including how frequently
we receive them, how relevant they are to NASA Earth science research,
and how unique they are. We don’t intend for this column to provide a
comprehensive picture of climate science; for a complete review of
global warming and climate change, please see our
Global Warming Factsheet.
