The models used by the IPCC are yet to provide realistic predictions for nitrogen emissions from the land to the air and water. Natural isotopic benchmarks offer a simple solution to this emerging global imperative.

The decline of the Great Barrier Reef can be reversed by improvements to governance and management: current policies that promote fossil fuels and economic development of the Reef region need to be reformed to prioritize long-term protection from climate change and other stressors.

Adaptation and geoengineering responses to climate change should be taken into account when estimating the social cost of carbon.

Builder of the global carbon budget.

Reform of carbon trading in Europe could help claw back its credibility as an instrument to cut emissions. Sonja van Renssen reports.

Fingers are often pointed directly at the news media for their powerful influence and ineffective reporting of climate change. But is that the best place to point? And are there more effective ways to conceptualize the power of the media and to consider whom they serve?

The shipping industry expects ongoing growth in CO₂ emissions to 2050, despite an apparent recent decline. Opportunities for decarbonizing the sector in line with international commitments on climate change need to be re-evaluated.

Climate change reports have been increasingly covered by the media but what drives the news stories and what is their power?

IPCC assessments present an unparalleled opportunity for climate science to speak directly to power. Re-thinking the summaries written for policymakers would enable scientists to communicate far more effectively with political leaders and the public.

In the light of its potential benefits, some scientists have been using the concept of risk to frame their discussions of climate change. At the moment, the media hardly pick up on risk language, so can anything be done to encourage them?

Current climate engineering proposals do not come close to addressing the complex and contested nature of conceivable 'climate emergencies' resulting from unabated greenhouse-gas emissions.
