Your next flight could be the single biggest contribution to global warming you make all year. Experts imagine how we might travel in future, without the 'flygskam'.
The use of fossil fuels has to end and be replaced by sustainable energy as quickly as possible. The Paris Agreement was a good start but states continuing to work together is key.

Geology will be key to any green transition, but its academic reputation needs an urgent makeover.
Emissions are seen from an oil refinery in Alberta.
As a wealthy nation with global diplomatic and multilateral influence, Canada is among a small subset of nations uniquely positioned to act individually and collaboratively on climate change.
Climate scientist James Hansen, who has spoken out about the dangers of climate change, was arrested in 2010 alongside Appalachian residents.
Some climate scientists have spoken out about the dangers of climate change. But a new study shows those voices may not be very influential.
Popular climate movements are gaining momentum around the world.

Populism focuses on charismatic individuals. Environmentalism is all about collective action on collective solutions. How do they come together?
Research shows the cost of damage through climate change will be much greater than the costs of reducing emissions.
New Zealand is small and generates a tiny fraction of global greenhouse gas emissions, but investment in cutting emissions is important and could influence other, larger countries.

Environmental charities are worried about speaking out about climate change during the upcoming federal campaign for fear Elections Canada will consider their activities as "partisan."
Waves in Australia’s southern coasts are likely to get bigger and faster under a warming climate.

A warming climate will affect the way waves hit over 50% of the world's coastlines, increasing erosion and the risk of flooding.
Climate change has caused pollen seasons to start sooner and last longer.
Allergic reactions to pollen may occur at different times of the year and for prolonged periods, and this will worsen with climate change.

Fossil fuels are heating the atmosphere – but the fact that we're burning them may not be the only reason.

As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.

The Haiyan Typhoon disaster is a cautionary case for climate adaptation and mitigation because it demonstrates the seductiveness of survival myths.
The inability to meet Pacific Island expectations on climate change will erode Australia’s leadership credentials and influence in the region.
Australia ensured its official communique watered down commitments to respond to climate change, gaining a hollow victory.
The IPCC is based in Geneva, Switzerland.

Every word of the 40-page summary document has to be agreed by representatives of 195 governments.
Pacific leaders don’t want to talk about China’s rising influence – they want Scott Morrison to make a firm commitment to cut Australia’s greenhouse gas emissions.
It's becoming increasingly obvious that Australia's inability – or refusal – to take firmer action on climate change is undermining its entire 'Pacific step-up'.
Since the last ice age, the ice sheet retreated over a thousand kilometres in the Ross Sea region, more than any other region on the continent.
New research shows that ocean and air temperatures both contributed to the melting of Antarctica's Ross Ice Shelf in the past, but melting from below by a warming ocean became more important over time.
Artist Albert Robida imagined in 1882 how air travel might look in future.
More than a century since humans learned to fly, we need to revolutionise how we stay up there.
