Arctic sea ice may be declining faster than expected -study

Arctic sea ice may be thinning faster than predicted because salty snow on the surface of the ice skews the accuracy of satellite measurements, a new study from the University of Calgary said on Tuesday.

The report from the Canadian university’s Cryosphere Climate Research Group published in the academic journal Geophysical Research Letters found satellite estimates for the thickness of seasonal sea ice have been overestimated by up to 25 percent.

That means the Arctic Ocean could be ice-free much sooner than some scientific predictions, which forecast sea ice will first disappear completely during summer months between 2040 and 2050, according to lead author Vishnu Nandan.

Ice-free summers in the Arctic Ocean would impact global weather patterns by increasing the magnitude and frequency of major storms, and alter the Arctic marine ecosystem, making it harder for animals like polar bears to hunt.

Microwave measurements from satellites don’t penetrate the salty snow very well, so the satellite is not measuring the proper sea ice freeboard and the satellite readings overestimate the thickness of the ice.

Wildfires

Forest fires stoke record loss in world tree cover

Forest fires in Brazil and Indonesia contributed to a record loss in global tree cover in 2016, equivalent to the size of New Zealand, that could accelerate deforestation blamed for climate change, an independent forest monitoring network said on Monday.

Man-made global warming increased the risks of wildfires by adding to extreme heat and droughts in some regions, according to Global Forest Watch (GFW). This year, California and Portugal have been among places suffering deadly blazes.

The combination of forest fires with land use change and climate change could speed destruction in areas like the Amazon and contribute to emissions of carbon dioxide, one of the gases that contribute to global warming, the report said.

Worldwide, global tree cover losses rose 51 percent in 2016 from the previous year to 297,000 square kilometers (114,672 square miles), according to data from the University of Maryland compiled by Global Forest Watch (GFW). That was a record high for GFW records stretching back to 2000.

Disease

Marburg virus – Uganda

On 17 October 2017, the Ugandan Ministry of Health notified WHO of a confirmed outbreak of Marburg virus disease in Kween District, Eastern Uganda. The Ministry for Health officially declared the outbreak on 19 October 2017.

As of 24 October, five cases have been reported – one confirmed case, one probable case with an epidemiological link to the confirmed case, and three suspected cases including two health workers.
