The Mediterranean region, with its biodiversity, climate, demographics, and economic activities such as tourism, agriculture and fisheries, is particularly vulnerable to environmental risks.
Iconic ecosystems, from coral reefs to Tasmania’s ancient forests, are collapsing across the continent and into Antarctica. It’s not too late to act — in fact, our lives depend on it.
The electricity sector is expected to play a key role in Canada’s push to net-zero emissions. Enhancing long-distance transmission can be lower the cost of providing clean and reliable electricity.
While Australia doesn’t generally experience such extreme winter temperatures, our electricity systems are still vulnerable to climate change, extreme weather and power outages.

New Zealand has put just over half of its NZ$50 billion pandemic stimulus towards clean energy, but several fossil fuel powered projects will slow down the country’s shift to a low-emissions economy.
The weather-related impacts of climate change will increasingly threaten critical infrastructure in the future. Shifting electricity grids towards microgrids could help.
The unprecedented intensity of two summers of bushfires, first in the east and then in the west, offered harsh lessons for Australians. One is that some settlements must retreat from high-risk areas.
Permanently protecting large, mature forests is a faster and cheaper way to stabilize Earth’s climate than complex carbon capture and storage schemes, and more effective than planting new trees.
