A coral reef in the Red Sea that can resist rising water temperatures could be the key to saving dying reefs in others parts of the world, a team of scientists from Switzerland and Israel has discovered. In a study conducted by Lausanne University, Lausanne federal technology institute EPFL and scientists at two institutions in Israel, corals in the Gulf of Aqaba, in the Red Sea, were found to be resistant to the effects of global warming and ocean acidification, EPFL said in a statement as the results were published in the Royal Society Open Science journal on Wednesday. Over a six-week period researchers exposed the corals to higher water temperatures and acidification to mimic the summer conditions of a future ocean in that region if sea temperatures continue to rise at their current rate. Most corals put under the same stresses “would probably bleach and have a high degree of mortality,” said EPFL scientist Thomas Krueger. However with the Gulf of … [Read more...] about Swiss scientists help discover coral reef that could survive global warming
Temperature rise due to global warming
Nasa has revealed that 2016 was the hottest year on record and this year could be hotter still thanks to raising levels of carbon dioxide.Soaring temperatures will cause floods, droughts, superstorms and wildfires to wreak utter havoc on our planet, leading scientists have warned.It is the third consecutive year of record-breaking heat, a first in the modern era.Data from Nasa and the UK Met Office shows temperatures were around 0.07 degree Celsius above the 2015 mark.Including the year 2016, 15 of the hottest 16 years on record have occurred since 2001, according to the National Oceanic and Atmospheric Administration (NOAA).The El Niño phenomenon played a role but scientists suggest the main factor was human emissions of CO2."2015 has been the warmest year on record up until now, so 2016 has just beaten that and and it's beaten that by about 0.1- 0.12 of a degree Celsius, which doesn't seem like a lot, but in terms of the year to year variations it's actually huge," Dr … [Read more...] about NASA reveals that 2016 was the hottest year EVER and 2017 could bring floods, droughts, SUPERSTORMS and wildfires if temperatures rise
Without mentioning Donald Trump by name, US Secretary of State John Kerry said during a two-day visit to Antarctica that Americans may have to take to the streets to persuade the president-elect that global warming is real and poses an existential threat to the planet. Trump has dismissed climate change as a hoax being perpetrated by China, and has said he would "cancel" the US commitment to the landmark Paris Agreement on global warming, which was signed by more than 190 countries last December. "We need to get more of a movement going," Kerry said during comments to several hundred scientists and staff at an evening event at McMurdo Station, the large base which is the hub for US operations. "We need to get more people to engage." Kerry, the highest-ranking US official to visit the continent, said there was a risk that much of Antarctica's ice will eventually melt into the sea, raising ocean levels around the world. While the Paris Agreement calls for cutting carbon … [Read more...] about Kerry makes push for Paris climate deal ahead of global warming conference in Morocco
Ohio State University scientists have found that since 1958 average temperatures at the American Byrd research station in the middle of the vast reaches of western Antarctica have risen by 2.4 degrees Celsius (4.3 Fahrenheit). That is one of the fastest gains ever recorded on the planet and three times the global average, according to the study group led by Professor David Bromwich. "A continued rise in summer temperatures could lead to more frequent and extensive episodes of surface melting" in western Antarctica, said their report. And, the stakes could be "much higher" if restraining ice shelves on the fringe of the western Antarctica broke and unleashed massive glaciers into the sea, added co-researcher Andrew Monaghan. A similar process has already taken place around the Antarctic Peninsula – below Chile – where several massive ice shelves that floated on the adjacent ocean broke loose in recent years. Grim predictions Sea levels have risen globally by about 20 … [Read more...] about Alarm over Antarctica temperature rise
As chances of a white Christmas are getting lower due to global warming and rising temperatures, in many places around the world snow is no longer a certainty, even in countries which are used to experience a fairly white Christmas. This year, record-high degrees are expected in some cities. One of the main talking points is whether or not it'll indeed be a white Christmas, a term which is used to describe snow on Christmas day. Users on social media are weighing in on the topic. Using the hashtag #nosnow, people are sharing their view of what is essentially a #GreenChristmas. Many memes are being shared to show that winter is not coming anytime soon. In the small suburb of Markham, right outside of Toronto, Canada, citizens are used to a below-zero temperatures during the holiday, but will now face no less than 15 degrees instead. Photos from all around the world are being shared online to show how the day before Christmas looks like where users are located. This photo is from … [Read more...] about #NoSnow: Brace yourselves for an unusually warm Christmas
Every year 250 million people are affected by natural disasters. Since 1992 the international community has spent some $2.7 billion (1.9 billion euros) to help mitigate the impact of hurricanes, floods and droughts. The organization Global Risk Forum in Davos, Switzerland, has specialized in identifying risks of any kind to society. Its president Walter Amman is convinced that climate change will lead to more disasters due to extreme weather. Amman told Deutsche Welle that he believes that we no longer can or should argue that we merely register events more quickly and accurately than 20 years ago. "If you look at the number of those events over the last 10 years, then it is clear that they have increased in number," he added. Local variations in impact of global warming Wildfires raging in Greece destroyed large forest areas north of the capital Athens in August The German Committee on Disaster Prevention (DKKV) also sees climate change as a reason for the ever larger … [Read more...] about More natural disasters due to climate change?
2 degrees Celsius Keeping global warming below 2 degrees Celsius (3.6 degrees Fahrenheit) is a target for tackling climate change adopted by the UNFCCC at COP16 in 2010. As far back as the 1970s, scientists predicted that a global temperature rise of 2 degrees C would set in motion devastating and irreversible consequences. More recently, scientists have warned that around this temperature, ice sheets will begin to melt at an uncontrollable rate, resulting in massive sea level rise. 400 ppm In March 2013, the global concentration of carbon dioxide (CO2) in the atmosphere stayed over 400 parts per million for a month for the first time in recorded history - and perhaps for the first time in 25 million years. Some scientists had considered this to be a milestone - albeit a negative one - for climate change. CO2 concentration of 400 ppm represents a rise of 85 ppm since measurements began in 1958. And scientists add that the rate of change is increasing to an alarming 2.75 ppm per … [Read more...] about Climate talk: decoding the global warming jargon
Nobel Prize laureate and climate advocate Al Gore said Tuesday that prompt action is necessary to prevent the potentially irreversible melting of the planet's ice. The former US vice president co-chaired a conference devoted to melting ice in the town of Tromso in northern Norway. Gore told foreign ministers and climate change scientists that the ice was melting faster in the Arctic and in Greenland than the worst-case projections by experts a few years ago. "The ice is also melting in West Antarctica and in mountainous regions across the globe," Gore said. "This conference is a global wake-up call." The scientific evidence for action at the UN climate summit in Copenhagen in December was continuing to build up week by week, he said. Norway's foreign minister Jonas Gahr Stoere said peaceful cooperation in the Arctic was crucial, as the region's five bordering countries vie for potentially lucrative natural resources. "High North, low tension," Stoere told reporters. "We will, … [Read more...] about Melting ice could accelerate global warming, says Gore
Climate change may soon transform oceans teeming with complex life into simple ecosystems that can no longer support the billions of people relying on them as a primary source of food, according to a new study . Unabated warming and ocean acidification will devastate numbers of zooplankton and smaller fish with a knock-on effect for larger carnivorous fish, according to the meta-analysis, which combines data from more than 600 experiments measuring the effects of climate change on ecosystems. Only microorganisms are expected to increase in number and diversity. "Our analysis projects decreases in species abundance across many types of organisms. There will be a species collapse from the top of the food chain down," said Ivan Nagelkerken, lead author on the paper and ASC Future Fellow at the University of Adelaide’s Environment Institute in South Australia. Warmer waters and acidity are also killing coral and oyster reefs. In the US, oyster farms are already spending large … [Read more...] about Global warming may cause ocean species collapse
With wisps of morning fog drifting across the surface of the Irrsee, ecologist Harald Ficker lowers a thermometer into the deep blue water to measure the Earth's global warming fever. Since the 1970s, the water has warmed about 2 degrees Celsius (3.6 degrees Fahrenheit) - twice as fast as the global average. Although that may be nice for early-season visitors to the popular swimming lake near Salzburg, it's not so good for fish. Global warming has been disrupting ecosystems here, and in lakes around the world. As temperatures continue to rise, that will affect fisheries, water supplies, farming, recreation and energy production - prompting scientists to consider how to make lakes more resilient to climate change. Ficker monitors lakes for the Austrian environment ministry. As he takes readings at different depths, he describes the changes. In spring, the ice has been melting a month earlier than in 1975. With the ice gone, the top layer of water heats up. Measurements show that the … [Read more...] about Can we save our lakes from global warming?
