38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change      (via sciencedaily.com)     Original source 

Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.

Substantial global cost of climate inaction      (via sciencedaily.com)     Original source 

Pioneering study reveals that limiting global warming to 1.5 degrees Celsius could reduce the global economic costs of climate change by two thirds. If warming continues to 3 degrees Celsius, global GDP will decrease by up to 10 percent -- with the worst impacts in less developed countries.

From defects to order: Spontaneously emerging crystal arrangements in perovskite halides      (via sciencedaily.com)     Original source 

A new hybrid layered perovskite featuring elusive spontaneous defect ordering has been found, report scientists. By introducing specific concentrations of thiocyanate ions into FAPbI3 (FA = formamidinium), they observed that ordered columnar defects appeared in the stacked crystalline layers, taking up one-third of the lattice space. These findings could pave the way to an innovative strategy for adjusting the properties of hybrid perovskites, leading to practical advances in optoelectronics and energy generation.

Paradox of extreme cold events in a warming world      (via sciencedaily.com)     Original source 

The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.

Scientists develop framework to measure plastic emissions and bolster U.N. efforts to reduce pollution      (via sciencedaily.com)     Original source 

Scientists have developed a framework for measuring plastic emissions akin to the global standard for measuring greenhouse gas emissions. The approach boosts identification of the biggest contributors to plastic pollution from local to national levels and could help improve strategies in reducing emissions worldwide if incorporated into a global agreement on plastic pollution. Using Toronto as a model, the researchers estimated that in one year alone, Toronto emitted nearly 4,000 tonnes of plastic pollution.

Fires that devastate wildland-urban interface areas are becoming more common around the globe, a trend that is likely to continue for at least the next two decades, new research finds. Such fires are especially dangerous, both because they imperil large numbers of people and because they emit far more toxins than forest and grassland fires.

Hidden threat: Global underground infrastructure vulnerable to sea-level rise      (via sciencedaily.com)     Original source 

As sea levels rise, coastal groundwater is lifted closer to the ground surface while also becoming saltier and more corrosive. A recent study compiled research from experts worldwide showing that in cities where there are complex networks of buried and partially buried infrastructure, interaction with this shallower and saltier groundwater exacerbates corrosion and failure of critical systems such as sewer lines, roadways, and building foundations.
