Flood clusters are not unknown - but what’s new about the floods hitting Lismore is the unprecented height.
Climatic drivers over the past 80 years have resulted in flowering season starting in late winter instead of spring.

The US is shifting to a new set of climate ‘normals’ – data sets averaged over the past 30 years. But normal is a relative concept in a time of climate change.
Humans are not very sensitive to changes in air pressure, but they can have a big effect on the weather.
Extreme temperatures in Cordoba, Spain in June 2017.
In an unchanging climate, we would expect record-breaking temperatures to get rarer as the observation record grows longer. But in the real world the opposite is true - because we are driving up temperatures.

Three years ago The Australian newspaper launched a broadside at the Bureau of Meteorology. But when it did it again this week, it seemed to get less traction from the top echelons of government.
A new paper improves our estimate of the climate’s sensitivity to carbon dioxide.
A new analysis suggests that weather records have not yet had time to capture the full effects of climate change, some of which are likely to take centuries to play out.

Weather forecasting stopped looking for patterns in the past, and started using numbers to look solidly at the future.

The record floods of 1954 and 1974 still stand as Lismore’s high-water marks. But Tropical Cyclone Debbie delivered her deluge far more abruptly than the rains that triggered those historic floods.

New South Wales has just had its hottest summer on record – an event that was made 50 times more likely by humans’ impact on the climate.
Heatwaves killed thousands of people in India and Pakistan in 2015.
Across the globe, extreme heat events are linked with climate change, although El Niño provided a boost in 2015 leading to more records being broken.
The past century hasn’t seen the worst drought that Australia’s climate can throw at us.
A new millennium-long record reveals that Australia has suffered longer droughts and wet periods than those recorded in the past century’s weather observations.
It’s all a matter of perspective.

Former PM’s business advisor Maurice Newman recently claimed that satellite temperature data tell a different story to data collected on the ground. He’s right - but that’s how it’s meant to be.
Tennis fans at the 2014 Australian Open were treated to days of temperatures above 40C.

2014 saw heatwaves of all kinds and other wild weather. Research can now explain that climate change made these events much more likely.
Yes, it’s been cold. But the hot weather just keeps on getting hotter.

Melbourne, Canberra and much of southern Australia have shivered through a cold winter. But on a longer view, record cold snaps are disappearing, while Australian heat records continue to be broken.
Despite adjustments to temperature data in the Arctic, the overall global warming trend remains the same.

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…
Adjusted data from Australian weather stations has been peer-reviewed before. But the government’s new technical panel could still offer useful advice.
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…
What does Paraguay have to do with the global temperature record?
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…
El Niño means drought in Australia – and floods in America.
It’s confirmed: 2014 produced the highest global temperatures since records began in the 1880s. As if that’s not cause enough for concern, this year threatens to see the return of El Niño, which like some…
Nationals MP George Christensen told Parliament that the hot temperatures of 1896 have been “wiped from the official record”. It’s a bit more complicated than that.
