2013 was Australia’s hottest year, warm for much of the world

The Bureau of Meteorology has confirmed 2013 as Australia’s hottest year since records began in 1910. Average temperatures over the continent have been 1.2C above the 1961-1990 average, breaking the previous…

Explainer: what is climate sensitivity?

Humans are emitting CO2 and other greenhouse gases into the atmosphere. As these gases build up they trap extra heat and make the climate warmer. But how much warmer? Scientists have long understood that…

How cold has it really been in the northern hemisphere?

If you are one of the many people with a larger than normal heating bill for recent months, you would probably be under the impression that it has been exceptionally cold in the northern hemisphere. We’ve…

Hot summer? Yes: the hottest

This summer hasn’t just felt hot. It’s been hot. In fact, the summer of 2012-13 is now the hottest on record. Average temperatures beat the record set in the summer of 1997-98, and daytime maximum temperatures…
Australia has always had heat waves, but the current one is far from typical. Daniel Alexander Head

What’s causing Australia’s heat wave?

Australia has started 2013 with a record-breaking heat wave that has lasted more than two weeks across many parts of the country. Temperatures have regularly gone above 48°C, with the highest recorded…

On global temperatures, Berkeley’s BEST is similar to the rest

The Berkeley Earth Surface Temperature (BEST) study recently found that global land-surface temperatures have increased by about 1°C since the 1950s — and 1.5°C since the mid-18th century. These results…
