Australian Bureau of Meteorology

The Bureau of Meteorology is Australia’s national weather, climate and water agency. Its expertise and services assist Australians in dealing with the harsh realities of their natural environment, including drought, floods, fires, storms, tsunami and tropical cyclones. Through regular forecasts, warnings, monitoring and advice spanning the Australian region and Antarctic territory, the Bureau provides one of the most fundamental and widely used services of government.

What is the relationship between carbon dioxide and temperature rise? Werner Wittersheim

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 much can we burn? That depends on the future we want. Aaron Muderick

Setting a carbon budget to keep below two degrees

We have already committed the planet to a certain amount of warming due to past carbon emissions. But efforts to reduce emissions now and over the next few decades will critically affect the degree of…

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…
