The price tag of phasing-out coal      (via sciencedaily.com)     Original source 

Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.

How climate change will affect malaria transmission      (via sciencedaily.com)     Original source 

A new model for predicting the effects of climate change on malaria transmission in Africa could lead to more targeted interventions to control the disease according to a new study. Previous methods have used rainfall totals to indicate the presence of surface water suitable for breeding mosquitoes, but the new research used several climatic and hydrological models to include real-world processes of evaporation, infiltration and flow through rivers. This groundbreaking approach has created a more in-depth picture of malaria-friendly conditions on the African continent.

Rock steady: Study reveals new mechanism to explain how continents stabilized      (via sciencedaily.com)     Original source 

Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism may explain how the cratons formed some 3 billion years ago, an enduring question in the study of Earth's history.

Millions in costs due to discharge of scrubber water into the Baltic Sea      (via sciencedaily.com)     Original source 

Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study shows that these emissions caused pollution corresponding to socio-economic costs of more than EUR 680 million between 2014 and 2022. At the same time, the researchers note that the shipping companies' investments in the much-discussed technology, where exhaust gases are 'washed' and discharged into the sea, have already been recouped for most of the ships. This means that the industry is now making billions of euros by running its ships on cheap heavy fuel oil instead of cleaner fuel.
