Climate change deniers hope that the current scientific
consensus is a fad that will pass in time. They hope to obstruct
action long enough for the scientific consensus to change.
Scientists, on the other hand, point out that every passing year
adds more evidence that the planet is warming and the
consequences will be catastrophic. They point to warnings made
in the 1960s by scientists who probably wore bell bottom

Today, every national government and every national science

Physical Society (the association for physicists) says: The
evidence is incontrovertible: Global warming is occurring. If no

Earth’s physical and ecological systems, social systems,
security and human health are likely to occur. We
