Hopes rise for green economy boom at Africa Climate Summit

Renewables are thriving, with Africa breaking solar energy records – but action is needed to plug financing gap

The first signs of a takeoff of Africa’s green economy are raising hopes that a transformation of the continent’s fortunes may be under way, driven by solar power and an increase in low-carbon investment.

African leaders are meeting this week in Addis Ababa, Ethiopia, for the Africa Climate Summit, a precursor to the global UN Cop30 in November.

Loss of koala habitat shows ‘total failure’ of nature laws, conservationists say

More habitat has been given up legally in 2025 so far than any other year since the animals were listed as threatened, analysis shows

Spain and Portugal wildfire weather made 40 times more likely by climate crisis, study finds

Wildfires were 30% more intense than would have been expected without global heating, scientists say

The extreme weather that fuelled “astonishing” blazes across Spain and Portugal last month was made 40 times more likely by climate breakdown, early analysis suggests.

The deadly wildfires, which torched 500,000 hectares (1.2m acres) of the Iberian peninsula in a matter of weeks, were also 30% more intense than scientists would have expected in a world without climate change, according to researchers from the World Weather Attribution network.

‘We’re winning a battle’: Mexico’s jaguar numbers up 30% in conservation drive

Conservationists hope that in 15 years species will no longer be at risk of extinction in Mexico – but challenges remain

In 2010, Gerardo Ceballos and a group of other researchers set out to answer a burning question: how many jaguars were there in Mexico? They knew there weren’t many. Hunting, loss of habitat, conflict with cattle ranchers and other issues had pushed the population to the brink of extinction.

Ceballos and his team from the National Alliance for Jaguar Conservation (ANCJ) thought there were maybe 1,000 jaguars across the country. They decided to carry out the country’s first census of the animal to find out exactly how many there were. They found 4,100.

Murray Watt backs ‘no-go’ zones where development is banned – but not for Tasmania’s Robbins Island

Environment minister says scientific evidence did not convince government that remote island qualified

Australia’s environment minister, Murray Watt, has backed the creation of “no-go zones” where development will be banned in some places under a revamped nature law, but said Tasmania’s remote Robbins Island – the site of a contentious windfarm proposal – does not qualify.

Watt this week said the Albanese government would accelerate its plan to overhaul the Environment Protection and Biodiversity Conservation (EPBC) Act so that legislation was introduced to parliament this year, sooner than previously suggested.
