Trees have died in Rocky Mountain National Park, Colo., as climate change has intensified bark beetle infestations and drought.
As climate change alters temperature and precipitation patterns across the US, it is having especially severe impacts on national parks. These changes could happen faster than many plants and animals can adapt.
Morrison’s brush strokes on his own portrait are designed to create the image of a leader tuned to the voters’ concerns, rather than the “Canberra bubble”.
Morrison is tactically quicker than Turnbull, just as in his messaging he can cut through more sharply. He's more attuned to the emotional and knee-jerk drivers of today's politics.

It’s unlikely NSW will get the sustained rain needed to break the drought.
A new outlook from the Bureau of Meteorology forecasts a dry, warm spring – and not the sustained rain we need.
The 2016 Maple fire (photographed in July 2017) reburned young forests that had regenerated after the 1988 Yellowstone fires. More frequent high-severity fires are expected in the future as climate warms, which may change patterns of forest recovery.
Huge fires roared through Yellowstone National Park in the summer of 1988, scorching one-third of the park. Since then the park has been a valuable lab for studying how forests recover from fires.

Having an envoy for drought and a prime minister keen to visit drought-affected areas puts the government under pressure to do the wrong thing.
Morrison’s ministry and his comments when announcing it tell us his orientation in the energy area.
The Coalition's primary vote has plunged 4 points to 33%, and Labor's vote has jumped from 35% to 41%, in The Australian's poll, which comes as Morrison moved quickly to announce his ministerial team.
Fires burning in NSW are harbingers of what’s to come.

From Greece, to the UK, to Japan and even Sweden, a slew of places in the Northern Hemisphere are suffering extreme heat. And the chances of extreme heat records tumbling are growing all the time.
Globally consumers are increasingly taking charge of their own drinking water supply.
Unless African cities improve water management many will face severe water problems by 2035.
Cape Town narrowly avoided “Day Zero,” but that doesn’t mean the city is resilient to future water shortages.
Cape Town faced down "Day Zero" earlier this year, but that doesn't mean its water system is resilient. Other cities should also take note.
