Kochi: Climate change is taking a toll on fishery resources, with the consequent ocean warming and the rise of the sea level posing multiple threats to the marine ecosystem, a leading marine scientist said here on Thursday.

“The scientific community has to take steps to develop adequate technologies to reduce carbon footprints and international collaboration is necessary to undertake advanced research to tackle the issues being faced by the marine ecosystem,” B. Madhusoodana Kurup, vice chancellor of Kerala University of Fisheries and Ocean Studies (KUFOS), said at the Indo-EU workshop on marine ecosystem and climate in India.

The workshop was jointly organised by KUFOS and the Nansen Environmental Research Centre-India (NERCI) under the EU-INDO-MARECLIM project of the European Union.

“Climate change has direct impact on ocean resources. The consequent rise of sea surface temperature and habitat destruction are causing the disappearance of commercially important fish species,” he said.

“There are scientific challenges for ecologists, economists, and other social scientists, in understanding how human actions affect ecosystems, the provision of ecosystem services, and the value of those services.

“An effective strategy should be designed to manage, monitor and provide incentives that reflect the social values of ecosystem services,” said Kurup.

N.R. Menon, coordinator of the INDO-MARECLIM project and co-Chairman of NERCI, said the objective of the workshop was to establish scientific cooperation of India and the EU member states in areas of monsoon studies, protection of marine ecosystem and coastal zone management.

“The meet is aimed at initiating a tie-up with Europe to undertake serious research in these areas,” said Menon.

The INDO-MARECLIM project envisages developing an institutional network in India to embark on joint research ventures from a case to case basis.

The project aims at facilitating and improving cooperation between the EU members states, associated countries and India.

A Warmer Winter For The United States Due To El-Nino And Climate Change

While El Nino is the biggest factor in the forecast, long-term warming from human-caused climate change is a factor.

Winter looks wet and especially mild for much of the country, thanks to a weak El Nino brewing, U.S. meteorologists said.

The National Weather Service on Thursday predicted a warmer than normal winter for the northern and western three-quarters of the nation. The greatest chance for warmer than normal winter weather is in Alaska, the Pacific Northwest, Montana, northern Wyoming and western North Dakota.

No place in the United States is expected to be colder than normal, said Mike Halpert, deputy director of the government’s Climate Prediction Center.

The Southeast, Ohio Valley and mid-Atlantic can go any which way on temperature, Halpert said.

Overall the winter looks a lot like the last few, Halpert said.

“The country as a whole has been quite mild since 2014-2015,” Halpert said.

Winter weather expert Judah Cohen, of the private company Atmospheric and Environmental Research, uses different indicators to predict winter for the National Science Foundation. He also forecasted a warm winter, heavily based on weak snowfall in Siberia.

Precipitation

Halpert said the southern one-third of the United States and much of the East Coast could be hunkering down for a wetter than normal December through January. The chances are highest in southeastern Georgia and much of northern and central Florida.

Hawaii, Montana, Michigan, parts of Idaho, Wisconsin, northern Illinois, Indiana and Ohio are forecast to be drier than normal, with the biggest likelihood in Hawaii, Montana and Michigan.

The middle belt of the nation and some of the north from California to New York can go any which way on precipitation.

The weather service’s forecast doesn’t look at snow likelihood.

El Nino

Halpert said the biggest factor in the forecast is a likely El Nino , the natural warming of parts of the central Pacific Ocean that influences weather worldwide.

The El Nino hasn’t quite formed yet, but it’s almost warm enough. Meteorologists predict there’s a 75 percent chance it’ll be around this winter. But it will be weak, not strong like the El Nino that helped lead to the record warm 2015-2016 winter, Halpert said.

Background warming

While El Nino is the biggest factor in the forecast, long-term warming from human-caused climate change is a factor, too, Halpert said.

“All things being equal, the slight kick we get out of the climate signal does tilt things toward the warm side,” Halpert said.

But it’s not enough to outweigh other factors if they push toward cold.

“Even on a warming planet,” he said, “it doesn’t mean winter goes away and it’s never cold again.” (VOA)
