Climate affects us all

The global temperature seems to be in a record-breaking mood. While temperature began to rise more than a century ago, around the 1940s, it started to dip. There was a speculation of another ice age. It continued to dip until the mid-1970s, and, thereafter, it has been gradually increasing albeit with some variability in different years (top graph). The year 1998 was declared the warmest year in history. But the subsequent years were not as warm and it held its title until 2005, when again the record was broken by an extra rise of 0.02 °C.
