We still don’t know enough about questions such as where the tipping points are for Arctic ice melt.

The Paris agreement has given us some solid targets to aim for in terms of limiting global warming. But that in turn begs a whole range of new scientific questions.
Indigenous Australians continue to manage fire in a way that reduces the risk to property and people.

Every year homes are lost in bushfires. But what if we build our houses to withstand fire?
We don’t have to know exactly how high the sea might rise to start doing something about it.

Cuts to CSIRO climate jobs will see a reduction in effort on monitoring and measuring climate change, and an increase in efforts to do something about it. That's the most politically-sensible option.
Clearing mulga woodland in Queensland to open up land for cattle during drought.
We're going to have to adapt to climate change, but some of the options on the table could do more harm than good if they destroy the ecosystems that protect us.

Hundreds of cities worldwide have pledged to act against climate change. New York City's experience rebuilding after Hurricane Sandy offers useful lessons about making urban areas more resilient.
The Paris climate summit was historic as a political achievement but it's not clear how and when the hard problems of emission cuts and climate finance get tackled.
Climate change is predicted to hit Africa hard unless the continent puts in place adaptation plans.
Africa needs to work on adaption strategies if it is to overcome the harmful effects of climate change.
It can be hard to know how best to adapt to climate change.
Projects to help people adapt to climate change are essential. But no one really knows how much to spend, or even how to tell which projects are working.

We can live comfortably and sustainably in hot places – but we'll have to ditch the glassy skyscrapers.
Temperatures are set to rocket throughout the 21st century, but design lessons from history could help the gulf states stay cool.

Viewing human migration through the lens of natural history makes one thing clear: society needs to prepare for more migrations of people and the species we depend on.
Obama made a trip to Alaska to steer the national conversation to the effects of climate change.
Obama's trips to vastly different areas – New Orleans and Alaska – laid bare the rising costs of adapting to climate change, now and in the future.
Levees in New Orleans were unable to prevent flooding during Hurricane Katrina in 2005.
Delta cities in both rich and poor countries face uphill, and potentially costly, battle in containing risk from flooding.
London’s famous Shard is one big window, but bricks and wood are more efficient.
Air conditioning alone won't make global warming more bearable – architects must reinvent the window.
South Australia’s McLaren Vale is leading the way in adapting to climate change, but the future for vineyards is still uncertain.

The wine industry is sensitive to climate change, but grape growers also have the funding and knowledge to put themselves at the forefront of climate adaptation. Other farmers should watch with interest.
Only a small portion of Porto Novo, Benin, is built-up. The city is taking steps to combat climate change.
Porto Novo in Benin, Rouen in France and Da Nang in Vietnam are taking steps to mitigate the harsh effects of climate change, which will hit them hard if they don't.
A zebra crossing melts in Delhi during extreme heat.
The latest heatwaves in India have claimed at least 1,100 lives.
Cyclone Pam struck the developing island nation of Vanuatu in March 2015. Poorer nations are more exposed to environmental dangers so are more concerned about impacts that might increase the risk.

Who cares more about environmental issues: people in rich countries, or not-so-rich countries? A survey suggests it's those in poorer places who are more vulnerable to issues like climate change.
Drought-reduced crop yields could threaten food supply in Australia.
The Australian Academy of Science has warned that sick, older, poor and isolated Australians are at most risk from the health impacts of climate effects such as drought, fires, floods and heatwaves.
Climate change is affecting gender ratios in fish, and could hamper their ability to return to a 50:50 balance.
Warmer temperatures can throw off the gender balance in some species. But some fish can adjust their offspring's gender to compensate, but only if temperatures don't rise too high.
