Greenland's ice sheet melting seven times faster than in 1990s
Scale and speed of loss much higher than predicted, threatening inundation for hundreds of millions of people

Greenland’s ice sheet is melting much faster than previously thought, threatening hundreds of millions of people with inundation and bringing some of the irreversible impacts of the climate emergency much closer.
Ice is being lost from Greenland seven times faster than it was in the 1990s, and the scale and speed of ice loss is much higher than was predicted in the comprehensive studies of global climate science by the Intergovernmental Panel on Climate Change, according to data.
That means sea level rises are likely to reach 67cm by 2100, about 7cm more than the IPCC’s main prediction. Such a rate of rise will put 400 million people at risk of flooding every year, instead of the 360 million predicted by the IPCC, by the end of the century.
Sea level rises also add to the risk of storm surges, when the fiercer storms made more likely by global heating batter coastal regions. These impacts are likely to strike coastal areas all around the world.
“These are not unlikely events or small impacts,” said Andrew Shepherd, professor of earth observation at the University of Leeds, one of the lead authors of the study. “[These impacts] are happening and will be devastating for coastal communities.”
Greenland has lost 3.8tn tonnes of ice since 1992, and the rate of ice loss has risen from 33bn tonnes a year in the 1990s to 254bn tonnes a year in the past decade. Greenland’s ice contributes directly to sea level rises as it melts because it rests on a large land mass, unlike the floating sea ice that makes up much of the rest of the Arctic ice cap.
About half of the ice loss from Greenland was from melting driven by air surface temperatures, which have risen much faster in the Arctic than the global average, and the rest was from the speeding up of the flow of ice into the sea from glaciers, driven by the warming ocean.
Oceans have absorbed most of the excess heat arising from our disruption of the climate to date, and much of the carbon dioxide, but they are reaching the limits of their capacity to do so. Sea level rises are driven not only by melting ice but by the thermal expansion of the seas as they warm.
The scale and speed of the ice loss surprised the team of 96 polar scientists behind the findings, published on Tuesday in the journal Nature. The Ice Sheet Mass Balance Inter-comparison Exercise comprised 26 separate surveys of Greenland from 1992 to 2018, with data from 11 different satellites and comparisons of volume, flow and gravity compiled by experts from the UK, Nasa in the US, and the European Space Agency.
Erik Ivins, of the Nasa Jet Propulsion Laboratory in California, stressed that the findings – the most comprehensive survey yet of the ice sheet over the past few decades – were based on observations, rather than computer modelling.
“While computer simulation allows us to make projections from climate change scenarios, the satellite measurements provide prima facie evidence,” he said.
The peak year for ice loss, according to the observations, was 2011 when 335bn tonnes of ice were lost. Since then, the average rate has slowed to 238bn tonnes a year from 2013, but this does not include the most recent observations from this summer, which showed even more widespread melting.
Governments are meeting in Madrid for the second week of crucial UN talks on the global response to the climate emergency. Campaigners have been frustrated by the slow pace of the negotiations, despite growing public clamour, including a 500,000-strong march through the centre of the Spanish capital led by the Swedish climate activist Greta Thunberg.
Rachel Kennerley, a climate campaigner at Friends of the Earth, said: “We’re in a climate emergency – the impacts are coming thicker and faster every day. This latest research is yet more in an ever-growing pile of evidence which shows we need real action, not warm words. Governments need to stop dragging their feet and deliver real emissions cuts and real support for vulnerable people already experiencing the devastating effects of climate breakdown.”
The IPCC is the gold standard for climate science, but some experts are concerned that its findings do not take into account the potential for “tipping points”, thresholds beyond which climate breakdown accelerates and becomes catastrophic and irreversible.
Louise Sime, a climate scientist at the British Antarctic Survey, said of the new paper: “This finding should be of huge concern for all those who will be affected by sea level rise. If this very high rate of ice loss continues, it is possible that new tipping points may be breached sooner than we previously thought.”

#ArrestScottMorrisonForTreason The Drought and accompanying firestorm currently gripping Australia has been brought about, and is being managed, very deliberately. And the treasonous criminal racketeers masquerading as the Australian Government are using the drought they have purposely manufactured to push Agenda 21 onto the people of Australia. If you are an Australian, or you care about Australia and its people, please share this everywhere and help make this video viral. Please Share - Mirror - Reupload and repost this video Everywhere you can.
Please folks, I implore you to help because we are getting hammered here in Australia and this is no joke. The creek out the front has stopped flowing. Ive been in this area 52 years and these creeks have never been dry. Hideous droughts Ive seen, all the grass dead, but I have never seen the creeks stop flowing because they are all spring fed from aquifers below ground. But now they have harvested the water from the flood plains, they are draining the artesian basin and they have felled trees on the mountains and exposed the well springs to the sun and the springs have stopped flowing. And this NOT from "climate change". This is Deliberate! And its not just in the valley where I live. It is all the creeks around here on both sides of the ranges... the springs have stopped.... the sky is full of smoke outside and the sunlight is red.... it looks surreal... they are killing us, they are killing everything, all the wild life, everything, and they are driving the people into the cities. This is agenda 21 in full swing.

Swedish Behavioral Scientist Introduces Eating Human Flesh At Food Conference As Emergency Measure For Climate Change
Celia Farber
September 4, 2019 Updated: September 22, 2019
Climate change alarmism has taken a macabre turn that looks like satire, but isn’t.
It happened in Sweden.
At a summit for food of the future (the climate-ravaged future) called Gastro Summit, in Stockholm on Sept. 3 to 4, a professor held a PowerPoint presentation asserting that we must “awaken the idea” of eating human flesh in the future, as a way of combating the effects of climate change.
In a talk titled “Can You Imagine Eating Human Flesh?”, behavioral scientist and marketing strategist Magnus Soderlund from the Stockholm School of Economics argued for the breaking down of ancient taboos against desecrating the human corpse and eating human flesh.
He refers to the taboos against it as “conservative” and discusses people’s resistance to it as a problem that could be overcome, little by little, beginning with persuading people to just taste it. He can be seen in his video presentation and on Swedish channel TV4 saying that since food sources will be scarce in the future, people must be introduced to eating things they have thus far considered disgusting—among them, human flesh.
Easier sells he suggests include pets and insects, but human flesh was the central topic. In Swedish articles describing this new debate, the term “mannisko-kotts branschen” is introduced. This means “the human flesh industry.”
In his bio at the Stockholm School of Economics, Soderlund states that his research focus includes “consumer behavior,” “marketing stimuli,” “loyalty, emotions, justice perceptions,” “psychological reactions,” and “in a society increasingly obsessed with consumption.”
People can be “tricked,” Soderlund teases, into “making the right decisions.”
Conflating resistance to eating human flesh with capitalist selfishness, the seminar’s talking points ask:
“Are we humans too selfish to live sustainably?
“Is cannibalism the solution to food sustainability in the future? Does Generation Z have the answers to our food challenges? Can consumers be tricked into making the right decisions? At GastroSummit, you will get some answers to these questions—and also partake in the latest scientific findings and get to meet the leading experts.”

A little more specific:
Convert all transportation to electrical and expand public transport. Subsidize the shit out of electrical cars so people can afford them
Retrofit buildings with solar panels, insulation, etc. Again, subsidize the shit out of it so people can afford it
Cut down on meat consumption (and mix seaweed with cow feed)
Carbon pricing / tax (if it's a tax, just divvy it up and send out a check to everyone, Alaska style. Free money!)
Build out renewable energy everywhere and shut down coal plants (eat shit Bob!)
Invest heavily in power storage to smooth out variations in wind / solar coverage
Upgrade the electrical grid
Wind down the oil industry and retrain people to work in the renewable energy sector
CO2 sequestration
Stop deforestation and plant trees everywhere
Sanctions and divestment targeting the worst offenders
Throw a lot of money at developing nations to help them avoid going the coal for growth route (with no strings attached. It's in everyone's interest)
Start experimenting with geoengineering in case we ever need it
Tell climate change deniers to go fuck themselves (this one's purely aesthetic)
