Is global warming occurring or not?

Yes, global warming is still happening. After the record average global temperature set in 1998, there were several years of slightly lower temperatures, and some sceptics said that temperatures had reached a new plateau and were now stabilising, while others claimed that the world was actually cooling. However, the 1998 record was matched again in 2005 and slightly exceeded in 2010. Climate scientists say that the last ten years were the warmest since instrumental records began in 1850.
