the biggest, thickest chunk of Arctic ice just broke apart, never seen that.
Great!
no other aspect of anything is impacted by temperature/co2 except vegetation and fauna

Ah. Well, I'm sure we will get to see if humans will survive that. Most wouldn't.
Unexpected Future Boost of Methane Possible from Arctic Permafrost
Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing.
Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms as permafrost thaws.
The impact on the climate may mean
an influx of permafrost-derived methane into the atmosphere in the mid-21st century, which is not currently accounted for in climate projections.
The Arctic landscape stores one of the largest natural reservoirs of organic carbon in the world in its frozen soils.
But once thawed, soil microbes in the permafrost can turn that carbon into the greenhouse gases carbon dioxide and methane, which then enter into the atmosphere and contribute to climate warming.

two Americans win Nobel Prize for economics related to climate change:
https://www.reuters.com/article/us-n...-idUSKCN1MI0UNAmericans William Nordhaus and Paul Romer, pioneers in adapting the western economic growth model to focus on environmental issues and sharing the benefits of technology, won the 2018 Nobel Economics Prize on Monday.
"according to one analysis"
Pure pseudoscience. Thank your proving out the OP.
A1.2. Warming greater than the global annual average is being experienced in many land regions and seasons, including two to three times higher in the Arctic. Warming is generally higher over land than over the ocean. (high confidence) {1.2.1, 1.2.2, Figure 1.1, Figure 1.3, 3.3.1, 3.3.2}
A1.3. Trends in intensity and frequency of some climate and weather extremes have been detected over time spans during which about 0.5°C of global warming occurred (medium confidence). This assessment is based on several lines of evidence, including attribution studies for changes in extremes since 1950. {3.3.1, 3.3.2, 3.3.3}
A.2. Warming from anthropogenic emissions from the pre-industrial period to the present will persist for centuries to millennia and will continue to cause further long-term changes in the climate system, such as sea level rise, with associated impacts (high confidence), but these emissions alone are unlikely to cause global warming of 1.5°C (medium confidence) {1.2, 3.3, Figure 1.5, Figure SPM.1}

https://www.cbsnews.com/news/donald-...in-2018-10-14/Lesley Stahl: Do you still think that climate change is a hoax?
President Donald Trump: I think something's happening. Something's changing and it'll change back again. I don't think it's a hoax, I think there's probably a difference. But I don't know that it's manmade. I will say this. I don't wanna give trillions and trillions of dollars. I don't wanna lose millions and millions of jobs. I don't wanna be put at a disadvantage.
thanks for posting
the report was dumbed down to reach vanilla consensus. Actual disaster is much worse
shutup meg
I'd say they threw caution to the wind on this one. The best case scenario is now 1.5 degree rise by 2100 with a 4 degree rise likely.
tipping points, positive feedbacks all over the place, BigCarbon's is hitting all the fans
Trash's own Exec says 4 degrees, but they don't care. BigCarbon makes govt policy for its own protection/enrichment.
Mammals Will Still Be Recovering From Human Destruction Long After We’re Gone
A somber new study estimates that it could take several million years for mammal diversity to recover from humanity’s impact.
Humans have helped propel the extinction of more than 300 mammal species — equaling a staggering loss of 2.5 billion years’ worth of unique evolutionary history,
It could take many millions of years for mammals to evolve enough new species to recover from the destruction humans have caused,
“We are doing something that will last millions of years beyond us,”
it could take up to 5 to 7 million years for mammal diversity to be restored to the level it was before the arrival of modern humans — and that’s assuming people cease all poaching, pollution and habitat destruction in the next 50 years.

What a ed up species man is.
"some say" God gave man dominion over the earth, and man ed it up. God is a lobbyist for BigCarbon

muh beer
https://www.wired.com/story/climate-...ost-of-a-beer/The team looked at the areas around the world that grow barley, which is turned into malt for beer, and projected what will occur under five different climate warming scenarios by 2100. Using models of both economic activity and climate change, the group made predictions about what will happen to barley production, as well as beer price and consumption.
During the most severe climate events, the study predicts that global beer consumption would decline by 16 percent, an amount about equal to the total annual beer consumption of the United States in 2011. It also expects average beer prices to double. Each country would be affected differently. The price of a single pint of beer in Ireland, for example, will rise by $4.84, followed by $4.52 in Italy and $4.34 in Canada. American tipplers will see beer prices rise up to $1.94 under the extreme events, the study said, and barley farmers will export more to other nations.

rapid glacier melt in Yukon:
“We’re seeing a 20% difference in area coverage of the glaciers in Kluane national park and reserve and the rest of the Unesco world heritage site [over a 60-year period],” Diane Wilson, a field unit superintendent at Parks Canada, told the CBC. “We’ve never seen that. It’s outside the scope of normal.”
In the St Elias range, researchers have found warming intensifies at higher al udes – a phenomenon they are not quite able to explain.
“These types of events aren’t isolated to glacial events in the St Elias,” said Zac Robinson, the report’s co-author and professor at the University of Alberta. “We’re slated to lose 80% of the ice cover in the Rocky Mountains over the next 50 years.”https://www.theguardian.com/world/20...ukon-shrinkingThe rate of warming in the north is double that of the average global temperature increase, concluded the US National Oceanic and Atmospheric Administration in its annual Arctic Report Card, which called the warming “unprecedented”.
Oceans have absorbed 60% more heat than estimated.
