Australia’s climate in 2015: cool to start with a hot finish

El Niño dominated global climate in 2015, but in Australia the story was more complicated. 2015 was Australia's fifth warmest year on record, and saw the return of very dry conditions to parts of Australia.

Odds keep rising for a big El Niño in 2015

El Niño has arrived, it's getting stronger, and it's not about to go away soon. And already there are rumblings that this could be a big one.

The climate ‘hiatus’ doesn’t take the heat off global warming

Over the past decade, warming air temperatures at Earth's surface appear to have slowed. But that ignores the vast majority of heat going steadily into the ocean. And, a new paper shows, that makes no difference to the long-term prognosis.

Global warming trend unaffected by ‘fiddling’ with temperature data

Attacks on institutions that keep records of global temperatures, such as NASA, the US National Oceanic and Atmospheric Administration, the UK Met Office, and Australia’s Bureau of Meteorology, continue…

Bureau’s weather records to be reviewed again – sure, why not?

The federal government’s new “Technical Advisory Forum” on weather data, announced by parliamentary environment secretary Bob Baldwin last week, will “review and provide advice on Australia’s official…

Why scientists adjust temperature records, and how you can too

An article in The Australian today has once again raised the question of why scientists, in trying to estimate how the global and regional surface temperatures of Earth may have changed over the past century…

Why room temperature needed to be taken down a notch

What is a healthy room temperature? On releasing its Cold Weather Plan for 2014, Public Health England has recently revised its recommended minimum levels to keep in good health. No longer, they say, do…

The journey to the other side of absolute zero

Absolute zero is the temperature (-273.15C) at which all motion in matter stops and is thought to be unreachable. But recent experiments using ultracold atoms have measured temperatures that are, in fact…

Smart urban design could save lives in future heatwaves

Heatwaves — Australia’s biggest natural killers — are getting more frequent and hotter thanks to climate change. One day cities such as Melbourne may see unprecedented heat, perhaps 48C or higher. But…

Human hands are all over Australia’s hottest ever year

2013 was Australia’s hottest year on record, but how much of that was due to human-caused climate change? Today scientists publish five research papers that reveal the extent of human influence on Australia’s…
A new study finds overwhelming odds that humans have contributed to higher global temperatures – so how much are we willing to gamble that it’s wrong? Kraevski Vitaly/Shutterstock

99.999% certainty humans are driving global warming: new study

There is less than 1 chance in 100,000 that global average temperature over the past 60 years would have been as high without human-caused greenhouse gas emissions, our new research shows. Published in…
