Climate Change Report Actually Understates Threats (thebulletin.org) 396
"Dire as it is, the latest IPCC report is actually too optimistic," writes Slashdot reader Dan Drollette. "It ignores the risk of self-reinforcing climate feedbacks pushing the planet into chaos beyond human control. So says a team of climate experts, including the winner of the 1995 Nobel for his work on depletion of the ozone layer." From their article:
These cascading feedbacks include the loss of the Arctic's sea ice, which could disappear entirely in summer in the next 15 years. The ice serves as a shield, reflecting heat back into the atmosphere, but is increasingly being melted into water that absorbs heat instead. Losing the ice would tremendously increase the Arctic's warming, which is already at least twice the global average rate. This, in turn, would accelerate the collapse of permafrost, releasing its ancient stores of methane, a super climate pollutant 30 times more potent in causing warming than carbon dioxide.
By largely ignoring such feedbacks, the IPCC report fails to adequately warn leaders about the cluster of six similar climate tipping points that could be crossed between today's temperature and an increase to 1.5 degrees -- let alone nearly another dozen tipping points between 1.5 and 2 degrees. These wildcards could very likely push the climate system beyond human ability to control. As the UN Secretary General reminded world leaders last month, "We face an existential threat. Climate change is moving faster than we are.⦠If we do not change course by 2020, we risk missing the point where we can avoid runaway climate change, with disastrous consequences."
In related news, a court in The Hague "has upheld a historic legal order on the Dutch government to accelerate carbon emissions cuts, a day after the world's climate scientists warned that time was running out to avoid dangerous warming. Appeal court judges ruled that the severity and scope of the climate crisis demanded greenhouse gas reductions of at least 25% by 2020 -- measured against 1990 levels -- higher than the 17% drop planned by Mark Rutte's liberal administration. The ruling -- which was greeted with whoops and cheers in the courtroom -- will put wind in the sails of a raft of similar cases being planned around the world, from Norway to New Zealand and from the UK to Uganda."
Meanwhile, a new article in GQ cites estimates that more than 70 percent of global emissions come from just 100 companies, complaining that "there is no 'free market' incentive to prevent disaster."

UN Predicts 50 Million Climate Refugees by 2010
Six years ago, the United Nations issued a dramatic warning that the world would have to cope with 50 million climate refugees by 2010. But now that those migration flows have failed to materialize, the UN has distanced itself from the forecasts. On the contrary, populations are growing in the regions that had been identified as environmental danger zones.
It was a dramatic prediction that was widely picked up by the world’s media. In 2005, the United Nations Environment Programme (UNEP) and the United Nations University declared that 50 million people could become environmental refugees by 2010, fleeing the effects of climate change.
But now the UN is distancing itself from the forecast: “It is not a UNEP prediction,” a UNEP spokesman told SPIEGEL ONLINE. The forecast has since been removed from UNEP’s website. —Spiegel Online

Fears of a "population explosion" were widespread in the 1950s and 1960s, but the book and its author brought the idea to an even wider audience
In 1948, two widely read books were published that would inspire a "neo-Malthusian" debate on population and the environment: Fairfield Osborn’s Our Plundered Planet and William Vogt’s Road to Survival. Although, they are now much less well known than Population Bomb, they inspired many works such as the original Population Bomb pamphlet by Hugh Everett Moore in 1954 that inspired the name of Ehrlich's book, as well as some of the original societies concerned with population and environmental matters.[3] D.B. Luten has said that although the book is often seen as a seminal work in the field, the Population Bomb is actually best understood as "climaxing and in a sense terminating the debate of the 1950s and 1960s.”[14] Ehrlich has said that he traced his own Malthusian beliefs to a lecture he heard Vogt give when he was attending university in the early 1950s. For Ehrlich, these writers provided “a global framework for things he had observed as a young naturalist."[3]

From the article you linked to:
One main reason for this slowdown is technical constraints: going 100% renewable (or even 50%) is not trivial. Baseload plants will have to disappear completely even as sufficient dispatchable capacity remains available. Utility umbrella group BDEW is thus calling for more new gas turbines to be constructed (in German), and companies like Uniper (formerly Eon) is currently investigating its options (in German). So are municipal utilities, such as the one in Cottbus that recently announced plans to switch from locally produced lignite to natural gas (in German). Amidst all of the reports about records with renewables and power exports, this little news item deserves more attention: a municipal utility in one of Germanyâ(TM)s three largest lignite mining areas (Lausitz) is switching to gas.
So, Germany is not replacing nuclear and coal with wind and solar but with natural gas. Perhaps more importantly this is replacing domestic coal and uranium with imported natural gas. Much of this comes from the not so friendly Russians.

Maybe we could build some nuclear power plants while we figure out how to make wind and solar power work? Nuclear power is as much a "zero emissions" energy source as wind and solar. Nuclear power is already competitive in price but national energy policy puts it in an impossible situation compared to wind.
http://www.world-nuclear.org/i... [world-nuclear.org]
In states with deregulated electricity markets, nuclear power plant operators have found increasing difficulty with competition on two fronts: low-cost gas, particularly from shale gas developments, and subsidized wind power with priority grid access. The imposition of a price on carbon dioxide emissions would help in competition with gas and coal, but this is not expected in the short term. Single-unit plants which tend to have higher operating costs per MWh are most vulnerable. The basic problem is low natural gas prices allowing gas-fired plants to undercut power prices. A second problem is the federal production tax credit of $23/MWh paid to wind generators, coupled with their priority access to the grid. When there is oversupply, wind output is taken preferentially. Capacity payments can offset losses to some extent, but where market prices are around $35-$40/MWh, nuclear plants are struggling. According to Exelon, the main operator of merchant plants and a strong supporter of competitive wholesale electricity markets, low prices due to gas competition are survivable, but the subsidized wind is not. In 2016 the subsidy (production tax credit) is $23/MWh. Though wind is a very small part of the supply, and is limited or unavailable most of the time, its effect on electricity prices and the viability of base-load generators âoeis hugeâ.
Wind power gets all the breaks on making money. This is pushing up energy prices and forcing nuclear power plants out of business. This means more natural gas plants

Has it? With one of the earlier reports at least, a bunch of scientists who worked on it refused to sign their name to it because the rather alarmist tone of the report's (political) summary did not at all match the much milder conclusions drawn in the actually scientific part.

But first, let me demonstrate what a pile of horseshit you just linked to.
The article was written in 2014, based in data through 2013, and talks about a "15 year pause in global warming". 2013 - 15 = 1998. 1998 when it happened was the hottest year ever by a huge margin --an outlier. It was also a massive El Niño year, and El Niño is a weather event that produces unusually warm years..
This is a classic technique of statistical misrepresentation: cherry picking a baseline to obtain the comparison you want. If you start in 1997 or 1999, the "disappearance" of warming disappears. If you use a moving average, even just a *two year* moving average, the disappearance also disappears. In other words, the supposed pause is just statistical horseshit.
Cherry picking a baseline year is possible because weather isn't climate. Some years are warmer than the underlying climate trend and others are cooler than the trend. Sometimes you have a run of several years that are over or under, and in fact this is normal with real data. It's just like flipping a coin 13 times. It's normal to get runs of heads and tails, even with a fair coin.
El Niños, which produce warm years, and La Niñas, which produce cool years, are not predicted by climate models because they are both random weather events, like flipping a coin.
Of the 15 years of the Horseshit Pause, six were La Niña event years, a number of them particularly strong ones, however some of them were record warm years for La Niñas. Five were El Niño years, but relatively weak ones. So basically over the Horseshit Pause, we had a run of events which produce cooler weather than the underlying climate trend; even so the Horseshit Pause was the warmest decade on the instrumental record.
Now you extend the Horseshit Pause period to include the following four years, you happen to get the four hottest years on the instrumental record: 2016, 2015, 2017, 2014. Note that 2016 and 2015 were El Niño, but 2017 was a La Niña year and should have been a cool one.
More to the point, if you make the run of years just a little bit longer supposed inconsistency of the climate models from the weather record disappears.

Well, the claim is that unless we reduce our CO2 output then we will see temperatures rise. If temperatures keep rising then at some point 1998 will no longer be the maximum. It's been the maximum for 20 years now, when can we expect this to no longer be true?
The 1998 peak was tied again in 2002, and has been broken in 2005, 2007, 2009, 2010, 2013, 2014, 2015, 2016, and 2017. See here for detailed table: https://data.giss.nasa.gov/gis... [nasa.gov]
The annual anomaly (Jan through Dec) in 1998 was +0.62 degrees C. The highest year so far is 2016, with +0.99 degrees C. We haven't been under the 1998 value since 2011.

You know, the ozone layer threat was (and still is, although it's slowly recovering) a real thing, and only because we eventually got every single country to agree and ban certain chemicals, it was slowed down and finally started to recover (giving the clueless know-it-all's a chance to claim the threat was a hoax; sometimes I wonder if we should have just let it continue and not having to hear this BS now, although not seriously).
"In 1976 atmospheric research revealed that the ozone layer was being depleted by chemicals released by industry, mainly chlorofluorocarbons (CFCs). Concerns that increased UV radiation due to ozone depletion threatened life on Earth, including increased skin cancer in humans and other ecological problems[4], led to bans on the chemicals, and the latest evidence is that ozone depletion has slowed or stopped."
Today, not even most climate sceptics wouldn't claim that the "scare" was unfounded, false or hoax... But then there are total nutcases, like you apparently, who prefer to not actually read anything outside of their prejudices.
