The Daily Mail has a distinct political agenda when it comes to climate change, and should not be relied upon to present an accurate assessment. It's also simplistic to think that global average temperatures are going to follow a remorseless upward trend, year by year. However, it is the case that there a whole host of indicators of changes in climate around the world. One notable indicator this year was the record low level of ice extent in the Arctic summer.

This is an interesting project, because it's a project that was set up under the leadership of a physicist who was sceptical about man-made climate change, and who got project funding from the Koch brothers. The Koch brothers made their money through oil and gas and fund a number of right-wing groups and are definite climate change deniers.
The outcome of the BEST has been to confirm the results of pretty much every other climate research group, and Richard Muller, the lead scientist, has reversed his sceptical position and is now convinced about man-made climate change.
