Lolz. Really? Almost nowhere has the weather not gone off the rails. No study even needed anymore.

I did not cite an agenda based source. All I intended to link there is the heat wave graph from EPA. I didn't even read whatever was written below.
I'm not asking for any reconstruction of of extreme weather beyond the instrumental record. I'm in total agreement that there are limitations with that. I am saying that the instrumental record has zero evidence of extreme weather getting worse during our 150 year period of warming. Given everything we have been told, this should not be the case.

1 - There are multiple abrupt climate change events in the geologic record. For example, climate during the last glacial period was far from stable. There are at least 25 events involving an abrupt warming to near-interglacial conditions that occurred in a matter of decades.
2 - So we have these different proxies that give us information about past climate and ideally you don’t rely on just one. So instead you use a multi-proxy approach, multiple records to reconstruct the changes that have been going on. Things like tree rings, the composite oxygen isotope record, an aggregation of ocean core data, ice-core samples, etc.
The key is global mean temperature, not regional variations. And what we see is global deep ocean temperature data along with global tropical temperature data indicates global temperatures have returned to the Holocene maximum.
3- What we’ve learned through studying these long-term processes, these long-term records, is that carbon dioxide CO2 is the guerrilla in the climate system. CO2 controls these large scale shifts in climate over the Earth’s history. So if there’s more CO2, greenhouse gases, in the atmosphere either through the release of deep deposits or through the extraction due to chemical weathering it’s these large scale changes in greenhouse gases that tend to shift the significant modes in climate.
4 - If you'd rather be sitting at 400ppm than 280 then you're potentially looking at something approximating a Pliocene climate which was at 380ppm when temperatures may not have been more than 1-2°C warmer on global average compared with peak Holocene temperature.

Jong Rohnson shows how we got into the climate crisis today. There is an all out effort to overwhelm the truth with a bunch of bots or hired hacks who spew absolute bullshit to try to create doubt about the climate crisis. The fossil fuel companies have taken their strategy from the tobacco industry, and they have hired merchants of doubt.
The longer they can keep people from the truth, the more money they can make exploiting our future.

You don't think the IPCC doesn't look at all these studies? This is what SR15 has to say on droughts: "low confidence in the sign of drought trends since 1950 at global scale... likely to be trends in some regions of the world, including increases in drought in the Mediterranean and W Africa & decreases in droughts in central N America & NW Australia."
On rainfall: "There is high confidence that mean precipitation over the mid-latitude land areas of the Northern Hemisphere has increased since 1951"
"There is, in particular, low confidence regarding observed trends in precipitation in monsoon regions."
"for land regions where observational coverage is sufficient for evaluation, it was assessed that there is medium confidence that anthropogenic forcing has contributed to a global-scale intensification of heavy precipitation over the second half of the 20th century."
All they have is high confidence in higher mean precipitation in the Northern Hemisphere since 1950, and medium confidence in an intensification of heavy precip globally. Hardly "extreme." There is no observed trends for floods, wildfires, hurricanes, and tornadoes.

LOL seriously? You are touting sea levels rising to 3.3mm/year from 3.1? We're doomed.
Greenland has been warmer than today for the majority of the past 10,000 years.
The US and Europe could switch to 100% non carbon tomorrow and there is likely to still be sea level issues.

On droughts: "low confidence in the sign of drought trends since 1950 at global scale... likely to be trends in some regions of the world, including increases in drought in the Mediterranean and W Africa & decreases in droughts in central N America & NW Australia."
On floods: "There is low confidence due to limited evidence, however, that anthropogenic climate change has affected the frequency and the magnitude of floods."
On tropical cyclones: "Numerous studies towards and beyond AR5 have reported a decreasing trend in the global number of tropical cyclones and/or the globally accumulated cyclonic energy" and "there is only low confidence regarding changes in global tropical cyclone numbers under global warming over the last four decades."
Tornadoes and forest fires aren't mentioned, but you can be sure if the IPCC could find something, they would be in there.

We are so out of our depth that we are drowning as the ice caps melt and sea levels rise.
"2°C: BEYOND THE LIMIT
Extreme climate change has arrived in America"
https://www.washingtonpost.com/graph...OkXeYpgJFPy82c
Over the past two decades, the 2 degrees Celsius number has emerged as a critical threshold for global warming. In the 2015 Paris accord, international leaders agreed that the world should act urgently to keep the Earth’s average temperature increases “well below” 2 degrees Celsius by the year 2100 to avoid a host of catastrophic changes.
The potential consequences are daunting. The United Nations Intergovernmental Panel on Climate Change warns that if Earth heats up by an average of 2 degrees Celsius, virtually all the world’s coral reefs will die; retreating ice sheets in Greenland and Antarctica could unleash massive sea level rise; and summertime Arctic sea ice, a shield against further warming, would begin to disappear.
But global warming does not heat the world evenly.
A Washington Post analysis of more than a century of National Oceanic and Atmospheric Administration temperature data across the Lower 48 states and 3,107 counties has found that major areas are nearing or have already crossed the 2-degree Celsius mark.
— Today, more than 1 in 10 Americans — 34 million people — are living in rapidly heating regions, including New York City and Los Angeles. Seventy-one counties have already hit the 2-degree Celsius mark.
— Alaska is the fastest-warming state in the country, but Rhode Island is the first state in the Lower 48 whose average temperature rise has eclipsed 2 degrees Celsius. Other parts of the Northeast — New Jersey, Connecticut, Maine and Massachusetts — trail close behind.
— While many people associate global warming with summer’s melting glaciers, forest fires and disastrous flooding, it is higher winter temperatures that have made New Jersey and nearby Rhode Island the fastest warming of the Lower 48 states.
The average New Jersey temperature from December through February now exceeds 0 degrees Celsius, the temperature at which water freezes. That threshold, reached over the past three decades, has meant lakes don't freeze as often, snow melts more quickly, and insects and pests don't die as they once did in the harsher cold.
The freezing point “is the most critical threshold among all temperatures,” said David A. Robinson, New Jersey state climatologist and professor at Rutgers University’s department of geography.
The uneven rise in temperatures across the United States matches what is happening around the world.
Rhode Island is the first state in the Lower 48 whose average temperature rise has eclipsed 2 degrees Celsius.
In the past century, the Earth has warmed 1 degree Celsius. But that’s just an average. Some parts of the globe — including the mountains of Romania and the steppes of Mongolia — have registered increases twice as large. It has taken decades or in some cases a century. But for huge swaths of the planet, climate change is a present-tense reality, not one looming ominously in the distant future.
To find the world’s 2C hot spots, its fastest-warming places, The Post analyzed temperature databases, including those kept by NASA and NOAA; peer-reviewed scientific studies; and reports by local climatologists. The global data sets draw upon thousands of land-based weather stations and other measurements, such as ocean buoys armed with sensors and ship logs dating as far back as 1850.
In any one geographic location, 2 degrees Celsius may not represent global cataclysmic change, but it can threaten ecosystems, change landscapes and upend livelihoods and cultures.

"'Coal is over': the miners rooting for the Green New Deal
Appalachia’s main industry is dying and some workers are looking to a new economic promise after Trump’s proves empty"
Carl Shoupe, a retired coalminer in Harlan county, Kentucky, who worked as a union organizer for 14 years, said people in Appalachia need to start moving away from relying solely on the coal industry as an economic resource for the region.
“What we’ve been doing is trying to transition into the 21st century and get on past coal,” he said.
Those transition efforts are still being impeded by the coal industry, as Shoupe says the majority of property in the area is still owned by coal companies and they have denied his efforts to develop solar panel fields.
The Green New Deal, a resolution proposed by Ocasio-Cortez, calls on the federal government to transform the United States’ energy infrastructure and economy to deal with the climate crisis. The resolution includes a call to create millions of high-wage union jobs through a federal jobs guarantee and a just transition for vulnerable communities.
Republicans – and Fox News – have slammed the proposal. “It’ll kill millions of jobs. It’ll crush the dreams of the poorest Americans and disproportionately harm minority communities,” the US president said last month.

Shoupe doesn’t think so. “They have bushwhacked this Green New Deal, told all kinds of lies. For different people in different parts of the country, it means different things,” he said.
Stanley Sturgill, a coalminer for 41 years in Harlan county, Kentucky, explained the Green New Deal would open the door for elected officials to use the plan to render solutions needed in their own communities.
“If it was called the Red New Deal, it would be approved by now,” said Sturgill. “What you’re doing with the Green New Deal is you’re opening the door to infringe on the Republicans’ money and that’s what they’re afraid of. Republicans laugh and say you can’t pay for it. But if you tax everybody what they should be taxed, and I’m talking about the wealthy, there wouldn’t be a problem.”
Sturgill cited the coal companies that receive billions of dollars in annual government subsidies and tax breaks, while hiring expensive lawyers to fight paying black lung benefits to coalminers. “I fought seven years before I got my black lung benefits, and they were hoping I died before getting paid,” added Sturgill.
Thousands of coalminers are currently at risk of losing their pensions. The coalminers’ pension fund is estimated to become insolvent by 2022 as many of the companies that were paying into the fund have filed for bankruptcy. The Black Lung Disability Trust Fund that was founded to provide benefits to coalminers with black lung disease – a progressive disease that eventually suffocates sufferers – is also severely underfunded.

Fire devastation has gone down thanks to our increasingly better detection, mitigation, and fire fighting techniques.
Globally, according to the new data, the number of floods and other hydrological events have quadrupled since 1980 and have doubled since 2004, highlighting the urgency of adaptation to climate change. Climatological events, such as extreme temperatures, droughts, and forest fires, have more than doubled since 1980. Meteorological events, such as storms, have doubled since 1980.

1. Sure, I'm with you, but there is nothing abrupt about the warming of the past 150 years.
2. Right.
3. This isn't true, I addressed this in the post you are quoting.
4. This is highly speculative, but sure. There isn't any evidence that 1-2 degrees warmer would be bad for society, other than sea level rise, but that is a function of humans building along the coasts than anything inherently bad about the warmth.

"New Pentagon Report: “The effects of a changing climate are a national security issue”"
In the Fiscal Year 2018 National Defense Authorization Act, the U.S. Congress asked the Department of Defense (DoD) to provide a report on “vulnerabilities to military installations and combatant commander requirements resulting from climate change over the next 20 years.” That report was delivered to Congress yesterday, prosaically-titled Report on Effects of a Changing Climate to the Department of Defense.
The first sentence in the “background” section of the study is worth noting. It reaffirms that the DoD continues to take climate change seriously, as it has across four administrations, both Republican and Democrat. The sentence reads: “The effects of a changing climate are a national security issue with potential impacts to Department of Defense (DoD or the Department) missions, operational plans, and installations.”
There are many other important points covered in the report. It recognizes the impacts of climate change on missions, operational plans and installations, it highlights specific examples of climate impacts, it provides an overview of work that the Department is doing in this space, and it reveals that about 2/3 of the 79 military installations surveyed are already facing climate change-related risks (recurrent flooding at 15 bases, drought exposure at 43 bases, and wildfire risk to 36 bases).

I'm not buying the Easterbrook debunking. We have another proxy that suggests it was even warmer: https://phys.org/news/2018-06-ancien...y-thought.html
"Other records have shown that northern Greenland's climate was much warmer than people expected during those periods, and those results received justified skepticism," Axford said. "Now we have an independent record that confirms that when the Arctic warmed in the past, there was especially strong warming in northern Greenland."

"World food security increasingly at risk due to 'unprecedented' climate change impact, new UN report warns"
https://news.un.org/en/story/2019/08/1043921
"Climate Change Threatens the World’s Food Supply, United Nations Warns"
https://www.nytimes.com/2019/08/08/c...od-supply.html
The report, prepared by more than 100 experts from 52 countries and released in summary form in Geneva on Thursday, found that the window to address the threat is closing rapidly. A half-billion people already live in places turning into desert, and soil is being lost between 10 and 100 times faster than it is forming, according to the report.
Climate change will make those threats even worse, as floods, drought, storms and other types of extreme weather threaten to disrupt, and over time shrink, the global food supply. Already, more than 10 percent of the world’s population remains undernourished, and some authors of the report warned in interviews that food shortages could lead to an increase in cross-border migration.
A particular danger is that food crises could develop on several continents at once, said Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies and one of the lead authors of the report. “The potential risk of multi-breadbasket failure is increasing,” she said. “All of these things are happening at the same time.”

What's the Big Deal With a Few Degrees?

08-16-2019, 12:40 PM #674
From your quoted phys.org article:
There is one caveat. Well-known changes in Earth's orbit caused warming during the early Holocene and Last Interglacial periods. Today, warming stems from man-made sources and is happening much faster than warming during those interglacial periods. That means there is a chance that Earth might not respond to current-day warming in the same way.
"Past climate is our best analog for future warming, and our results hint that land at these very high latitudes in the Arctic may warm even more than predicted in the coming century," Axford said. "But nothing in Earth's past is a perfect analog because what's happening today is totally unprecedented."
Also worth mentioning, your article doesn't support the idea that "Greenland has been warmer than today for the majority of the past 10,000 years." Instead, what the article says, even according your own quotes, is it looks like Greenland is more sensitive to warming than previously thought.
