Heatwaves can cause a large number of deaths, especially when vulnerable groups are unprepared and are not acclimatised to hot temperatures.
It was a hot year for many Australians.
An annual assessment of the health of Australia's environment shows mostly stable conditions in 2017, but ecosystems on land and at sea suffered ever higher temperatures.
The British First Fleet knew little of conditions in Port Jackson, later Sydney Cove, before their arrival.

When the First Fleet sailed into Sydney Cove in 1788, they entered an ancient and unforgiving landscape. A new book charts Australians' relationship with one of the world's most volatile climates.
Floods in South East Queensland follow a 40-year cycle, and planners should take note.
Engineering practice assumes that floods are randomly distributed but science suggests they are not. This raises questions about the reliability of flood infrastructure and management strategies.
Extreme weather led to starfish mass strandings along beaches in Kent and East Yorkshire.

But it's too early to tell whether climate change is to blame.
People collect water piped in from a mountain creek in Utuado, Puerto Rico on Oct. 14, 2017, in the aftermath of Hurricane Maria. Hundreds of thousands of Puerto Ricans were still without running water.

Climate change threatens to widen the health gap between the haves and have-nots. Here's why addressing environmental issues that drive poor health is a starting point.

Many parts of the US have experienced extreme heat or extreme cold in the past year. Recent research projects that climate change will increase deaths from both types of weather, especially cold spells.
As many as 20 people are dead and dozens missing following the Southern California mudslides.

A watershed scientist explains why post-wildfire landscapes are so susceptible to landslides – and why those risks are poised to rise.
Seriously cold: The ‘bomb cyclone’ freezes a fountain in New York City.

An atmospheric scientist who studies the Arctic explains why – because of global warming – the U.S. may be in for longer cold spells in the winter.
The storm intensified rapidly off the US east coast.
The US was hit by a 'bomb cyclone' last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.
Frost affected many crops across WA during September 2016.

We already know that climate change makes heatwaves hotter and longer. But a new series of research papers asks whether there is also a climate fingerprint on frosty spells and bouts of wet weather.

You should never try to drive through floodwater, because you never know what's beneath the surface. And new research shows some roads are more treacherous than others.
Knowing about hailstones in advance would be preferable.

New "dual-pol" weather radars promise to spot large hailstones forming inside thunderstorms, giving people a heads-up when it's about to hail.

Five years after Superstorm Sandy, we see how disadvantaged social groups suffered more from the storm before and after – much as we're seeing in Hurricanes Harvey and Maria.
The intensity of heavy downpours in Houston has increased dramatically since the 1950s, leading some people to argue the city’s disaster planning and infrastructure are not up-to-date.

It's not just about rebuilding infrastructure after storms: Cities need to systematically rethink their knowledge systems which are at the heart of urban resilience.
A solar and battery-powered microgrid got San Juan’s Children’s Hospital quickly back online after Hurricane Maria.
Yes, Puerto Rico and any other storm-vulnerable location could benefit from on-site solar and battery backup, but it's unrealistic to say these microgrids are enough to power the island.
Flooding in Port Arthur, Texas during Hurricane Harvey, Aug. 31, 2017. According to the Climate Science Special Report released on Nov. 2, heavy precipitation events are becoming more frequent and intense in most regions of the world.

On Nov. 2 the White House posted a detailed climate science report without comment. The Trump administration is unlikely to heed it, but it could boost state, local and private sector action.
A fireman tackles one of the wildfires that swept through parts of California in October.
This year is poised to go down as the hottest non-El Niño year ever recorded, with record low polar ice and extreme weather that left many regions battling bushfires and hurricanes.
Cars are submerged on a flooded road in the Sydney suburb of Marrickville in 2012.
A massive residential development in a flood-prone inner-city suburb sounds like a recipe for disaster. But good urban design can deliver higher density and reduce the flood risk.
