Society’s defining issues are rarely presented as raw facts and stats, and climate change is no exception.
In shouting “system change not climate change”, young people understand that the 3-4℃ warmer world we’re headed for would be far more painful, costly and disruptive than any short-term costs or inconvenience we face from taking rapid, bold action.
Climate plans are the order of the day in the presidential primary campaign because carbon pollution is a global threat of unique proportions.
Cities are on the front line of climate change. While their footprints cover a mere two per cent of the Earth’s surface, they consume 78 per cent of global energy and account for over 60 per cent of greenhouse gas emissions.
Spring and summer 2017 were among the wettest on record in eastern North America.
Droughts are a natural feature of the Australian environment. But the Millennium drought (or “Big Dry”), which ran from 1997 to 2010, was a wake-up call even by our parched standards.

Climate Change: Having The Right Combination Of Tree Personalities Could Make Forests More Resilient
Every tree in a forest has a neighbour. In many forest neighbourhoods, the same species are often found living together, especially when the growing conditions are similar. Sometimes these neighbours are close and sometimes far apart, but collectively they form part of a community, with some species naturally being more dominant than others, especially in terms of biomass production.
New Orleans averted disaster this month when tropical storm Barry delivered less rain in the Crescent City than forecasters originally feared.

Local people collect water from a muddy waterhole in 2006 in San Marcos Tlacoyalco. The Tehuacan Valley South-East of Mexico City has long experienced severe water shortages. Drought and climate change have contributed to this but recent industrial growth has also strained the very limited ground water resource. Water resources in the area are largely based on a weekly delivery by truck as well as collecting water from small pools known as Jagueys.
A more strategic approach to urban growth can ensure our cities maintain adequate green space and become low-carbon, efficient and affordable.
Far from protecting U.S. interests, the tariffs are bound to stifle the current solar boom, destroying American jobs and dragging down clean energy innovation. As economists who research climate and energy policies that can foster a greener North American economy, we argue the government should instead create targeted subsidies that support innovation and lower costs across the supply chain.
You don’t need a supercomputer to predict how the weather above your head is likely to change over the next few hours – this has been known across cultures for millennia. By keeping an eye on the skies above you, and knowing a little about how clouds form, you can predict whether rain is on the way.
Most of us have a range of white goods (refrigerators, washing machines, etc.) in our homes. These white goods provide a host of benefits, but they also have significant environmental impacts, and it’s important to consider these when using and choosing white goods.
To maintain our capacity to address climate change, we need to recognize and address the trauma it creates.
