Governments should examine even small chances of the most severe impacts of global warming, study says

* Do more to understand worst warming scenarios - report

* Treat climate more like health, security-UK-backed study

OSLO, July 13 (Reuters) - Governments should treat climate change as seriously as threats to national security or public health, partly by focusing more on the worst scenarios of rising temperatures, an international report said on Monday.

Crop failures, extreme heat waves or high rates of sea level rise could be so harmful that governments should examine even small chances of the most severe impacts, according to the study by about 60 experts from 11 nations.

"The risks of climate change should be assessed in the same way as risks to national security or public health," according to the experts from countries that included Britain, the United States, China, Russia and India.

"When we think about keeping our country safe, we always consider the worst case scenarios," British Foreign Office Minister Joyce Anelay, whose government was among the report's sponsors, said in a statement.

"That is what guides our policies on nuclear non-proliferation, counter-terrorism and conflict prevention. We have to think about climate change the same way," she said.

Too often, risks of climate change are viewed more narrowly, "as if it were a long-term weather forecast", she said.

Almost 200 governments will meet in Paris in December to try to work out a global deal to slow climate change.

The study said U.N. reports about climate change focused mainly on moderate warming and rarely mentioned the impacts of five degrees Celsius (9 Fahrenheit) or more, which are far less likely but would be far more damaging.

The Greenland ice sheet, Arctic ecosystems and tropical coral reefs are systems vulnerable to big rises in temperatures.

Governments have long been at odds about how to present the risks of climate change, partly because some voters doubt scientific findings that warming is man-made. Spending on national security or health is less controversial.

The report said the world was not on track to limit greenhouse gas emissions to keep temperatures within a U.N. goal of two degrees Celsius (3.6 F) above pre-industrial times.

"It is very likely that the world will continue to follow a medium to high emissions pathway for the next few decades," the authors wrote. (Reporting By Alister Doyle; Editing by Gareth Jones)
