Climate resilience strategies in urban, rural areas      (via sciencedaily.com)     Original source 

Local decision-makers looking for ways to reduce the impact of heat waves on their communities have a valuable new capability at their disposal: a new study on vegetation resilience. Scientists completed a study of how well vegetation survived extreme heat events in both urban and rural communities across the country in recent years. The analysis informs pathways for climate mitigation, including ways to reduce the effect of urban heat islands.

Oil palm plantations are driving massive downstream impact to watershed      (via sciencedaily.com)     Original source 

The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.

Human activity is causing toxic thallium to enter the Baltic sea, according to new study      (via sciencedaily.com)     Original source 

Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.

Climate change and mercury pollution stressed plants for millions of years      (via sciencedaily.com)     Original source 

The link between massive flood basalt volcanism and the end-Triassic (201 million years ago) mass-extinction is commonly accepted. However, exactly how volcanism led to the collapse of ecosystems and the extinction of entire families of organisms is difficult to establish. Extreme climate change from the release of carbon dioxide, degradation of the ozone layer due to the injection of damaging chemicals, and the emissions of toxic pollutants, are all seen as contributing factors. One toxic element stands out: mercury.

How can forests be reforested in a climate-friendly way?      (via sciencedaily.com)     Original source 

Europe's forests have already been severely affected by climate change. Thousands of hectares of trees have already died due to drought and bark beetles. Scientists have now investigated which trees can be used for reforestation. Their findings: only a few tree species are fit for the future, such as English oak in the UK. However, mixed forests are important for the survival of forests, otherwise the forest ecosystem as a whole could be weakened.
