Future population growth is expected to take place almost entirely in cities. We won't fight climate change without them.
Modern science can be difficult or complex for one person to understand and verify, especially a non-scientist. So who should we believe when scientific evidence is met with denial?
Sceptics are not necessarily less intelligent or knowledgeable.
Without understanding why the 'fingerprint' has failed to appear our predictions about global warming - as carbon dioxide concentrations increase - are uncertain.
Cold polar water can stop the Arctic sea ice from melting – but what happens if it warms up?
Recently published research has found that the concentration of poorer people in hotter places is a real problem for cities' capacity to cope with climate change.
Lee: 'Business will be far from usual in a world of four, five or six degrees of warming.'
From solar canopies to wind towers, Masdar City provides a living laboratory for the latest sustainable design and technology.
A volcanic eruption in 1815 triggered a year without a summer – prompting a flowering of nature writing that is all too relevant today.
Atmospheric, marine, environmental, biological and medical scientists join in calling for more focus on the damage being wrought by climate change.
A new report published by the Climate Institute says Australia could avoid lengthy heatwaves and help save the Great Barrier Reef by meeting the Paris Agreement's 1.5C global warming goal.
Global temperatures are poised for another record-breaking year. As incomes rise around the world and global temperatures go up, the use of air conditioning is poised to increase dramatically.
For birds migrating to the top of the world, the warming climate could severely contract the available space they have to breed.
Was Malcolm Turnbull right to say that larger and more frequent storms are one of the predicted consequences of climate change – but that you can't attribute any particular storm to global warming?
The rhetoric of 'smart cities' is dominated by the economic, with little reference to the natural world and its plight. Truly smart and resilient cities need to be more in tune with the planet.
The level of carbon dioxide in the atmosphere is rising faster than at any point in the past 55 million years.
The city of Phalodi has set a temperature record for India, hitting 51℃. Until now, India's smog problem has curbed extreme temperatures. But that could be about to change.
A warming Earth could see invading species arrive in Antarctica via the floating "taxi service" of the sea. That could be a threat to the southern continent's delicate ecosystem.
New mapping shows how Antarctica's huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
