Earth warming to climate tipping point, warns study. Image copyright AP A warmer world will release vast volumes of carbon into the atmosphere, potentially triggering dangerous climate change, scientists warn.
Writing in journal Nature, they project that an increase of 1C (1.8F) will release an additional 55 billion tonnes of carbon into the atmosphere by 2050. This could trigger a "positive feedback" and push the planet's climate system past the point of no-return. Previous assessments have not taken carbon released by soil into account. Login. What is climate change? 2016 'very likely' to be world's warmest year. Image copyright Getty Images 2016 looks poised to be the warmest year on record globally, according to preliminary data.
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. “The communication of risk is something that most UN member states are not prepared to openly discuss, unless they happen to be Tuvalu or the Maldives or other South Pacific or Caribbean islands,” Lewis told the Guardian.
“Massive [climate-induced] displacement is a big problem that a lot of member states have dressed up as other kinds of issues. 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.
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. 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.
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). July was the hottest month the world has endured since records began in 1880, scientists have said, and brought a painful taste of the troubles people around the world may have to grapple with as global warming intensifies. Results compiled by Nasa showed the month was 0.84C hotter than the 1951-1980 average for July, and 0.11C hotter than the previous record set in July 2015. 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.
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. The climate crisis is already here – but no one’s telling us. What is salient is not important.
What is important is not salient. The media turns us away from the issues that will determine the course of our lives, and towards topics of brain-melting irrelevance. This, on current trends, will be the hottest year ever measured. National Oceanic and Atmospheric Administration. Evidence. BBC NEWS. Climate guide.

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. In Depth.
