Coastal areas in West Africa are under intense pressure from demographic growth, economic expansion and ongoing climate change.
Around the world, fragile coastal ecosystems are under intense pressure, and understanding and managing their complex interactions requires an integrated and interdisciplinary approach.
A holistic view of climate change risk considers climate hazards, exposure, vulnerability and the responses to these. It also takes into account how multiple risks interact.

Countries cannot be expected to all tread the same path to net zero emissions.
Humanity can still limit global warming to 1.5°C this century. But political action will determine whether it actually does. Conflating the two questions amounts to dangerous, misplaced punditry.
Prominent academics, including a former IPCC chair, round on governments worldwide for using the concept of net zero emissions to 'greenwash' their lack of commitment to solving global warming.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2℃ will pass us by.

Discord and doubt are the last things the world needs at this critical moment.

The NSW floods are a textbook example of the theoretical impacts we can expect on Australian rainfall as climate change continues.
Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.

The WHO has been criticised for being slow to recognise the scale of the COVID-9 pandemic. We suggest a new protocol on infectious diseases to help with faster data collection and more open sharing.
Three decades of growing scientific certainty about climate change have yielded little progress.
A new assessment found substantial warming is much more solidly assured than we thought.

Humanity at risk if we keep thinking everything is under control
Without a radical change of course on climate change, Australians will struggle to survive on this continent, let alone thrive.
For decades Australian scientists have, clearly and respectfully, warned about the risks to Australia of a rapidly heating climate. After this season's fires, perhaps it's time to listen.

Promising to plant 100m trees a year is one thing; making them grow can be quite another.
Indonesia will face new challenges as current released IPCC reported states that oceans and cryosphere are melting in accelerated rate.
Climate change is causing oceans to become warmer and more acidic and to lose oxygen. Indonesian waters are not immune to these impacts.
Climate modelling at the CEA.
The climate emergency requires the full mobilisation of scientific institutions, but the persistent compartmentalization between disciplines and difficulties of adaptation hinder their action.
Low lying regions could be devastated by sea level rise this century.
If nothing is done now, seas could rise a metre by 2100, and four metres by 2300.
Morrison declared defiantly Australia was ‘doing our bit’ and ‘we reject any suggestion to the contrary’.
While a new report from the IPCC highlights the need for urgent climate change action, Morrison used his address to the UN to strongly defend the government's performance on climate change.
The IPCC report provides fresh details on scope of the effects of climate change.

A new Intergovernmental Panel on Climate Change report makes clear human-induced climate change threatens the health and function of the ocean and cryosphere - the frozen regions of the Earth.
