High temperatures make droughts worse, right? Wrong: it's the other way around. Ahead of an El Niño summer that looks set to bring drought to much of Australia, here's a quick primer on how they form.
El Niño explained: how it works, what a mega El Niño this year could bring and how global warming might affect future El Niño-driven weather patterns.
El Niño is expected to bring heavy rains to drought-stricken California, but more rain alone won't solve the West's water crisis.
Historical analysis shows that natural forces are behind California’s drought, but global warming has contributed 8%-27% to the drought’s severity.
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.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
While global warming will continue, it's important to assess variability as well as long-term average climates.
Shifting air currents high up in the skies can have a big impact down on the ground.
Parts of the UK are sizzling thanks to Iberian air.
Forecasting successes can breed complacency in the general public. But all hurricane damage isn't necessarily contained within the "cone of uncertainty."
What explains the unusually dry and warm weather that's behind California's prolonged drought? And how is climate change contributing?
The "warm blob" of remarkably warm water in the Pacific is changing weather patterns and impacting marine life, providing clues to how ecosystems may change in a warmer future.
While eastern Australia trembles in the face of an El Niño, Western Australia's oceans could finally see relief from devastating marine heatwaves.
Antarctica's sea ice is changing in ways that scientists didn't predict, and is now causing headaches for Antarctic stations.
El Niño is officially on, and comparing it to previous events suggests it could be big one, perhaps leading to record-breaking temperatures.
This last year we were preparing for an El Niño. But then it all just fizzled out. So what happened? And could this be the year?
Extreme rainfall in Sydney is increasing - but only in summer, potentially leading to more flash floods in the city.
The recent wild weather that lashed New South Wales has been described as 'once-in-a-century'. But how often does it really happen?
What causes the wild weather that's hit Sydney and central New South Wales over the past 24 hours?
For a long time climate models have forecast increasing rainfall in tropics. Now we know part of the reason: clumpy thunderstorms.
