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.

Last year saw plenty of warm weather around the country, but other notable events included dry months in the southeast, some very cold winter nights, and record-warm dry season days in the north.

2017 brought wild, wacky and even deadly weather. Australia was hit by heatwaves and torrential rains, plus some surprisingly cool spells. Hurricanes hit America, and a killer monsoon lashed Asia.
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.
Pictures of ocean bays emptied of water as Hurricane Irma moved through the Caribbean and Florida show that storm surges can move away from the coast, as well as onto it.
This winter had some extreme low and high temperatures.

In 2017 Australia’s winter had the highest average daytime temperatures on record. This extreme is 60 times more likely to occur under the influence of greenhouse gas emissions.
Rainbows get their round shape from a process called reflection.

Meteorology researchers across the country are prepping experiments for the mini-night the eclipse will bring on August 21 – two minutes and 36 seconds without the sun in the middle of the day.
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.
Farmers don’t get efficient information on weather changes, improving data can change this.

Information to weather changes is often unavailable to Africa’s farmers and even if it does exist, the quality is poor or inaccessible to those who need it most.
‘Tropics’ may conjure images of sun-kissed islands, but the expanding tropical zone could bring drought and cyclones further south.

Climate Council CEO Amanda McKenzie told Q&A that heatwaves were ‘worsening’ in Australia and ‘hot days’ had doubled in the last 50 years. Let’s take a look at the evidence.
It might feel nippy, but look out for winter heatwaves.

Australia is looking at another mild winter – but while it sounds pleasant, it can increase bushfire risk and worsen drought. Winter heatwaves are actually (enjoyable) extreme weather events.
Does it make sense any more to talk about the weather – like record heatwaves in Sydney – as separate from the developing climate patterns we are seeing?
