The summer of 2015-2016 was the hottest on record for Australia's oceans.
Nice day for the beach. In fact there have been rather a lot of those in Sydney lately.

Sydney is in the process of smashing the record for the longest run of days above 26℃. Weather, El Nino and climate change are all playing their part.

Cyclone Winston produced wind speeds of around 300 km per hour, making it one of the strongest storms to make landfall.
Lake Mead in Arizona – water demand is outstripping supply in the Southwest as the weather has gotten warmer and the population has grown.
The U.S. Southwest drifted into a drier state during the last 35 years due to fewer rain-producing weather patterns and hotter temperatures.
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.
Pencil pines are found nowhere else in the world, and are extremely sensitive to fire.
Bushfires are threatening Tasmania's World Heritage area and ancient plants, warning us of a possible future under climate change.
Rural southern Australia has been drying out over the past several decades. Pictured here, Burra in South Australia.
Australia is the land of drought of flooding rains, driven by events such as El Nino. But despite this variability, some parts of Australia are clearly drying out.

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.
Despite a decade of drought and declining rainfall in parts of Australia, there’s still plenty of water to go around.

The Millennium Drought ended more than five years ago, but several years of below-average rainfall and El Niño have brought drought back to many parts of Australia. Our latest report on water in Australia shows rainfall is continuing to decline in eastern Australia and increase in the north.
Cumbria 2015 shows how we have failed to learn from two other 'one in 100-year events' in the past 15 years.
2015 looks set to be the hottest year on record.
2015 will likely be the hottest year on record, according to a preliminary analysis released by the World Meteorological Organization.

2014 saw heatwaves of all kinds and other wild weather. Research can now explain that climate change made these events much more likely.
From hot to cold and cold to hot, the weather can make a difference to our health.
Changes in temperature and season do affect our health – and not just when the weather turns cold.
A new real-time measuring buoy can change the way the maritime industry operates.
Enhanced data collection capabilities will ensure that information collected from the coastline will be seamless.
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.
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.
Really dry: a Colorado River aqueduct in southern California.
Historical analysis shows that natural forces are behind California’s drought, but global warming has contributed 8%-27% to the drought’s severity.
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.
