South Africa has been experiencing odd weather patterns during the month of November. It can be attributed to three culprits.

When disaster strikes, more people than ever are turning to social media to find out if they're in danger. But Australian emergency services need to work together more to learn what works to save lives.
Hurricane Patricia as it made landfall on the Pacific coast of Mexico.
False complacency: Hurricane Patricia didn't devastate Mexico as feared, but provides more evidence that warming waters raise the chances of more intense storms.
There were no fatalities from Hurricane Patricia, which was downgraded to a tropical storm after making landfall in Mexico.
Research shows that El Niño creates conditions for a certain type of hurricane – and offers clues as to how climate change can affect the severity of hurricanes.
Pretty, but also pretty nasty.

With El Niño ramping up, Australia is in for a long, hot, dry summer - perfect conditions for blue-green algae. And that innocuous-looking pond scum can pack a toxic punch if you're not careful.

Lake Kariba’s water evel is down to under 30% – and it may worsen.
The upcoming El Niño event may see an even bigger drop in the water level of Lake Kariba. This will have terrible consequences for the people using the river.

We thought the big El Niño might not bring drought. And then the climate turned dry. And hot.
New surveys show Australians don’t mind if the water coming from their tap is recycled.

Would you drink recycled water? New surveys suggest Australians concerned about water shortages are ready for alternative sources.
Drought is a quintessentially Australian experience, yet many of us don’t properly know how they form.

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 Nino brings drought to Indonesia, and warmer weather to almost the entire globe.
El Niño has a hugely pervasive effect on global temperatures - for every degree the tropical Pacific warms, land temperatures warm by 1.5 degrees. How? Because the tropical ocean is a very good heater.
This summer’s El Niño is likely to bring more frequent heatwaves to a large swathe of Australia’s north and east.
The link between El Niño and heatwaves is complicated. But what we can say is that this summer's strong El Niño conditions are likely to bring more heatwaves to much of Australia's north and east.

Storm clouds for California?
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.
Storms coming? El Niño is projected to lead to much-needed rain in California next year.
El Niño is expected to bring heavy rains to drought-stricken California, but more rain alone won't solve the West's water crisis.
Children from a village in Papua New Guinea’s Western Highlands Province stand in one of countless sweet potato gardens destroyed by frost across the country, August 2015.
Papua New Guinea is now facing a drought and frosts that look set to be worse than 1997, when hundreds of people died. So how can memories of 1997 save lives over the next few months?
People in the Philippines have been warned to brace for wet and wild weather, as this year’s El Nino shapes up to be the strongest since 1998.

The seesaw between El Niño and La Niña is set to get stronger with global warming. Signs are that this year and next will deliver a big swing from one to the other, prompting fires and floods across the world.
The large 1982 El Niño contributed to the Ash Wednesday bushfires that killed 75 people in south east Australia.
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.
