... The average temperature of the earth's surface has risen by 0.6 degrees C since the late 1800s. It is expected to increase by another 1.4 to 5.8 degrees C by the year 2100 -- a rapid and profound change. Even if the minimum predicted increase takes place, it will be larger than any century-long tren ...

Does climate change affect seismic activity?
... Does climate change affect seismic activity? Scientists developed the theory of plate tectonics using significant evidence including sea floor spreading, earthquakes and volcanic activity. The theory was refined over time through a process of review by the scientific community. Sometimes claims seem ...
