One cold winter doesn't negate more than a century of global warming. We need the political leadership to set the world on a safer path. Ill-informed tweets by government senators won't help.
Yes, some of this is normal seasonal transition. But at least a portion of it is due to a particularly vigorous cold front that swept across southeast Australia over the weekend.
Understanding when there will be extreme heat and extreme cold can help people prepare.

Going out in the cold won't necessarily lead to you getting a cold. But cold weather in general is more hospitable to viruses, so it's wise to take steps to keep your immune system strong.
Exercise improves physical health, immunity, and can reduce fatigue.
Exercise can improve mood and mental health, which may drop during the winter months.
We’ve learned much more about the novel coronavirus over the last few months, including that most spreading events occur inddoors.
As the coronavirus pandemic continues, and the colder weather approaches, new mathematical models are needed to study changing social behaviours and indoor spaces.
The study examined patterns of Twitter rage in hot and cold weather. Given anger spreads through online communities faster than any other emotions, the findings are important.
Although colder weather is linked to lower levels of physical activity, changing seasons provide unique opportunities to be active.

Keeping kids active in winter can be a challenge, as cold temperatures and icy conditions often mean more time indoors. Here's how to maintain a healthy activity level throughout Canadian winters.
It’s an age-old battle between parents and kids.
Leaving your coat at home on a cold winter day doesn't automatically mean you're going to get sick. But it could make you more susceptible to germs.

Life-threatening cold temperatures in the central US are caused by changes in wind circulation in the Arctic that bring cold air south. Climate change could make these events more frequent.
Snowpack protects tree roots and soil from harmful freeze/thaw cycles.
Climate change is shrinking winter snow cover in Northeast forests, which protects tree roots and soil from repeated freezing and thawing. This could stunt tree growth and forest carbon storage.
Heart attacks increase with lower air temperature, lower atmospheric air pressure, higher wind velocity, shorter sunshine duration and colder weather.
Doctors have long acknowledged heart attacks are more likely to occur in cold weather. But now a major study has confirmed it.
