2016 'very likely' to be world's warmest year

With data from just the first nine months, scientists are 90% certain that 2016 will pass the mark set by 2015. Temperatures from January to September were 1.2C above pre-industrial levels, according to the World Meteorological Organization (WMO). The body says temperatures should remain high enough for the rest of the year to break the previous record. El Nino has had an impact, but the most significant factor driving temperatures up continues to be CO2 emissions. Global sea levels are rising fast, so where does that leave the cities most at risk? Current projections of global average sea level rise are now expected to double by 2100, which would be severely damaging – if not disastrous – for many of the world’s coastal cities, from Ho Chi Minh City and Mumbai to New Orleans and Miami.

Yet the upcoming United Nations conference on sustainable urban development, Habitat III, is unlikely to create the international platform needed to tackle such a global threat, according to Dan Lewis, head of UN Habitat’s urban risk reduction unit. Ethiopia May Paradoxically Benefit From Climate Change. Suffering from corruption, poor sanitation, malnutrition, and enormous economic inequality, Ethiopia is a troubled nation to say the least.

Ethiopia May Paradoxically Benefit From Climate Change

However, a new study reveals that it may be getting a welcome boost from a most unlikely source – climate change. Writing in the journal Climatic Change, a team from Virginia Tech (VT) has concluded that the flow of water to the Ethiopian Blue Nile Basin (BNB) will likely increase as the world inexorably warms. This will allow crops to be grown throughout multiple seasons of the year, potentially rescuing its faltering agricultural sector. “For all the catastrophic impacts of climate change, there are some silver linings,” coordinating researcher Zach Easton, an associate professor of biological systems engineering at VT, said in a statement.

Climate change explained in six graphics. Climate change: 'Monumental' deal to cut HFCs, fastest growing greenhouse gases. More than 150 countries have reached a deal described as "monumental" to phase out gases that are making global warming worse.

Hydroflurocarbons (HFCs) are widely used in fridges, air conditioning and aerosol sprays. Delegates meeting in Rwanda accepted a complex amendment to the Montreal Protocol that will see richer countries cut back their HFC use from 2019. But some critics say the compromise may have less impact than expected. Three-way deal US Secretary of State John Kerry, who helped forge the deal in a series of meetings in the Rwandan capital, said it was a major victory for the Earth. Global sea levels are rising fast, so where does that leave the cities most at risk? Lives in the balance: climate change and the Marshall Islands. Watch the full video7 minutes There may be music in the roar of the sea, as Byron eulogized, but the waves can also bring creeping unease.

Lives in the balance: climate change and the Marshall Islands

On low-lying fragments of land like the Marshall Islands, the tides are threatening to take away what they previously helped support: life. Hilda Heine surveys the latest temporary sea wall that cleaves her property from the waves. It has been knocked down twice since February by floods and she frets about her plants that will probably face a salty demise. Climate Time Machine.

Ice loss labelled as 'extreme' 10 years ago is now considered commonplace. In March, the Arctic Ocean and surrounding seas recorded a low maximum extent, with rapid ice loss continuing through May.

While this rate of ice loss would have been considered extreme 10 years ago, Nasa now says it's 'kind of used to these low levels of sea ice’ and it should be considered the 'new normal.' World's hottest month shows challenges global warming will bring. In Siberia, melting permafrost released anthrax that had been frozen in a reindeer carcass for decades, starting a deadly outbreak.

In Baghdad, soaring temperatures forced the government to shut down for days at a time. In Kuwait, thermometers hit a record 54C (129F). Home : Volcanoes and Climate. Scientists warn world will miss key climate target. Leading climate scientists have warned that the Earth is perilously close to breaking through a 1.5C upper limit for global warming, only eight months after the target was set.

Scientists warn world will miss key climate target

The decision to try to limit warming to 1.5C, measured in relation to pre-industrial temperatures, was the headline outcome of the Paris climate negotiations last December. The talks were hailed as a major success by scientists and campaigners, who claimed that, by setting the target, desertification, heatwaves, widespread flooding and other global warming impacts could be avoided. However, figures – based on Met Office data – prepared by meteorologist Ed Hawkins of Reading University show that average global temperatures were already more than 1C above pre-industrial levels for every month except one over the past year and peaked at +1.38C in February and March. Keeping within the 1.5C limit will be extremely difficult, say scientists, given these rises.

What causes climate change? Just as the world’s most respected scientific bodies have confirmed that the Earth is getting hotter, they have also stated that there is strong evidence that humans are driving the warming (2). Scientists agree the main cause of climate change is human activities which magnify the ‘greenhouse effect’ – a natural process in which gases in the atmosphere warm the Earth by trapping heat that is radiating towards space (2) (4). A layer of greenhouse gases, including water vapour and smaller amounts of carbon dioxide, methane and nitrous oxide, act as a thermal blanket surrounding the Earth.

This absorbs heat and warms the surface to a life-supporting average of 15°C. As energy slowly escapes out of our atmosphere, some of it is absorbed by the greenhouses gases, which warms the Earth further. Carbon dioxide (CO2) is the main greenhouse gas of concern. Fossil fuels. National Centers for Environmental Information (NCEI) IntroductionWarming ClimateHuman InfluenceMore Information Introduction Many lines of scientific evidence show the Earth's climate is changing. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming. It is worth noting that increasing global temperature is only one element of observed global climate change. Precipitation patterns are also changing; storms and other extremes are changing as well.
