Scientists call for careful use of time scales, reference dates and statistical approaches in analyzing climate change trends to avoid distortion and hampering of response

Green Car Congress

Demonstrating that the use of different time scales, reference dates, and statistical approaches can generate highly disparate results in climate reports, scientists at the University of Alaska Anchorage argue that careful use of these tools is critical for correctly interpreting and reporting climatic trends in Alaska and other polar regions.

Study links increased black carbon pollution to increase in cases of lung adenocarcinoma worldwide

Green Car Congress

An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. This study, done in collaboration between NTU and the Chinese University of Hong Kong, showed that a 0.1 LSCC is often linked to a history of smoking. micrograms per cubic meter (?

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO 2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois. The carbon-related costs of converting the land to sugarcane fields were included in the analysis.

Study: air pollution causes 800,000 extra deaths a year in Europe and 8.8 million worldwide

Green Car Congress

—Co-author Professor Thomas Münzel, of the Department of Cardiology of the University Medical Centre Mainz. When we use clean, renewable energy, we are not just fulfilling the Paris Agreement to mitigate the effects of climate change, we could also reduce air pollution-related death rates in Europe by up to 55%.
