2017 is set to be in top three hottest years, with record-breaking extreme weather: finds report
Washington, Nov 6 (IBNS): It is very likely that 2017 will be one of the three hottest years on record, with many high-impact events including catastrophic hurricanes and floods, debilitating heatwaves and drought.
Long-term indicators of climate change such as increasing carbon dioxide concentrations, sea level rise and ocean acidification continue unabated. Arctic sea ice coverage remains below average and previously stable Antarctic sea ice extent was at or near a record low.
The World Meteorological Organization’s provisional Statement on the State of the Climate says the average global temperature from January to September 2017 was approximately 1.1°C above the pre-industrial era.
As a result of a powerful El Niño, 2016 is likely to remain the warmest year on record, with 2017 and 2015 being second and/or third. 2013-2017 is set to be the warmest five-year period on record.
The WMO statement – which covers January to September - was released on the opening day of the United Nations climate change conference in Bonn.
It includes information submitted by a wide range of UN agencies on human, socio-economic and environmental impacts as part of a drive to provide a more comprehensive, UN-wide policy brief for decision makers on the interplay between weather, climate and water and the UN global goals.
“The past three years have all been in the top three years in terms of temperature records. This is part of a long term warming trend,” said WMO Secretary-General Petteri Taalas. “We have witnessed extraordinary weather, including temperatures topping 50 degrees Celsius in Asia, record-breaking hurricanes in rapid succession in the Caribbean and Atlantic reaching as far as Ireland, devastating monsoon flooding affecting many millions of people and a relentless drought in East Africa.
“Many of these events – and detailed scientific studies will determine exactly how many – bear the tell-tale sign of climate change caused by increased greenhouse gas concentrations from human activities,” he said.
Patricia Espinosa, Executive Secretary of UN Climate Change which is hosting the Bonn conference, said: “These findings underline the rising risks to people, economies and the very fabric of life on Earth if we fail to get on track with the aims and ambitions of the Paris Agreement”.
“There is unprecedented and very welcome momentum among governments, but also cities, states, territories, regions, business and civil society. Bonn 2017 needs to be the launch pad towards the next, higher level of ambition by all nations and all sectors of society as we look to de-risk the future and maximize the opportunities from a fresh, forward-looking and sustainable development path, “she added.
Extreme events affect the food security of millions of people, especially the most vulnerable. A review of the Food and Agriculture Organisation (FAO) found that, in developing countries, agriculture (crops, livestock, fisheries, aquaculture and forestry) accounted for 26% of all the damage and loss associated with medium to large-scale storms, floods and drought.
According to the World Health Organisation (WHO), the global health impacts of heatwaves depend not only on the overall warming trend, but on how heatwaves are distributed across where people live. Recent research shows that the overall risk of heat-related illness or death has climbed steadily since 1980, with around 30% of the world’s population now living in climatic conditions that deliver prolonged extreme heatwaves. Between 2000 and 2016, the number of vulnerable people exposed to heatwave events has increased by approximately 125 million.
In 2016, 23.5 million people were displaced during weather-related disasters. Consistent with previous years, the majority of these internal displacements were associated with floods or storms and occurred in the Asia-Pacific region. In Somalia, more than 760 000 internal displacements have been reported, according to the UN High Commissioner for Refugees and International Organisation for Migration (IOM).
The latest International Monetary Fund (IMF) World Economic Outlook indicates that adverse consequences are concentrated in countries with relatively hot climates and which are home to close to 60% of current global population.
