How can we feed a growing world population while protecting the environment? One key strategy is to improve yields on small farms, which produce much of the food in the world's hungriest countries.
Warmer temperatures are likely to cause heat stress in cattle raised on natural pastures and in feedlots.
Drought is a massive problem for southern Africa. The region requires adaptation and mitigation strategies if it's to cope with the changing climate.
Iceland’s geothermal power plants are an ideal place to test pumping carbon dioxide underground.
An Icelandic trial shows carbon dioxide can be pumped underground and stored as rock.
Countries such as Mauritania have contributed little to climate change, yet face the worst impacts such as crop failure.
The countries that have contributed the least to climate change will experience the worst of its effects.
CSIRO still needs to focus on preventing the impact of climate change, such as drought, in Australia.
Any shift in the focus of climate change research at CSIRO should look at how to stop the problem and reduce its impact on Australia.

A key sticking point may be resolved at the Paris climate talks: but at what cost to developing countries?

Climate change leads to increased likelihood of drought, but strategies for mitigation could make things even worse. How can we resolve the conundrum?
Worldwide, the livestock industry is a bigger source of greenhouse gases than transport.

The recent Lancet Commission report rightly pointed out that climate change is a huge risk to global public health. But it shied away from one of the main issues: the world consumes far too much meat.
Acehnese fishers are among the quarter of the world’s population who live on the coast, and for whom climate-driven changes to the oceans would make life much harder.

Failing to stick to the world's agreed global warming limit of 2C won't just affect the atmosphere - it will play havoc with the oceans too, potentially ruining ecosystems on which much of humanity depends.
Unless Africa can manage the effects of climate change, the agricultural future for many African’s looks bleak.

Australia risks becoming a ‘fossilised’ economy unless we take action on climate change without delay.
Economic studies on the costs of climate action share a common message: action on climate change is cheap, and delaying it will be costly.

We need political intervention if southern African countries are to mitigate the effects of climate change.
How much money has Greg Hunt been given for Australia’s environmental programs?

Environment minister Greg Hunt hasn't asked for any more money for the Emissions Reduction Fund. So what is actually in the budget, as far as climate change is concerned?
Mitigation efforts could help alleviate the impacts of climate change on food security and agriculture in Africa.
Climate change is affecting all regions of the globe. But some places, such as Africa, are more vulnerable than others.
Countries are working towards meetings in Paris in November that could see the first global climate deal since the Kyoto Protocol.
Ahead of meetings at the end of this year in Paris, countries will submit draft contributions for a global climate deal. The goal: reducing greenhouse gases beyond 2020, and ultimately keeping global warming below 2C.

Some people might argue that the greatest moral challenge of our time is serious enough to justify deliberately tampering with our climate to stave off the damaging effects of global warming. Geoengineering…
The Gold Coast is one of Australia’s climate “hot spots” — vulnerable to rising seas, storms and erosion.
The world’s population could reach almost 10 billion by 2050. Most people will live in cities. To accommodate an additional 3 billion people, we’ll need to build the equivalent of one new city, that can…
