I always prefer Brzezinski's histories when narrated by Hollywood's most loquacious cowboys. How could we forget Rompin' Ronnie's rendition of "The Evil Empire", a serial in 3 parts.

What is BREEAM? Building Research Establishment Environmental Assessment Method.

“BREEAM, developed by the renowned building science center BRE (Building Research Establishment), measures the sustainability of construction projects, infrastructure, and buildings in a variety of key categories: energy, health and well-being, innovation, land use, materials, management, pollution, transport, waste, and water. Projects then receive ratings of either Pass, Good, Very Good, Excellent, or Outstanding.”

This one new administrative facility in Britain, due to design and construction methods has been certified as Outstanding, the highest rating available according to the world’s leading sustainability assessment standard, BREEAM.

Flooding returns to southern Queensland, Australia

www.aljazeera.com/news/2017/10/flooding-returns-southern-queensland-australia-171018105240759.html

Quote
This time the flooding is more widespread.

David de Paoli, a chilli and avocado grower, told the Australian Broadcasting Corporation (ABC) that he suffered more than a million dollars in losses from the most recent storm.

"This is it, the last time we had that 350mm it was quick and fast and furious it caused structural damage and soil erosion, but this one's costing us our crop," he said.

Fuck Kissinger. Every word out of that mouth is a lie, be it yea, or be it nay. For that man speaks not truth or falsity, but rather to enshrine his vision of the future.

We are, Kissinger warns, in the midst of a “sweeping technical revolution whose consequences we have failed to fully reckon with and whose culmination may be a world relying on machines powered by data and algorithms and ungoverned by ethical or philosophical norms.”

Well, would you know it? Henry Kissinger and his ilk are actually machines powered by data and algorithms!

while i concur 100% i think that 1.5 - 2.0C target was illusionary as well as intentionally deceptive from day one. i can't seriously say but i expect temps betweein 3-5C higher during my grandchildren's lifetime. if i'm too far off, let me know but if possible explaining why so that i can eventually correct something that i'm convinced of since 20+ years.

This is a story that could go in many threads on this forum. But here is a highlight: Storing your water in aquifer contaminated with arsenic is not a good idea:

" ... officials also have known since 2006 that the area’s groundwater — with which the recharged Colorado River water mixes — has levels of arsenic and fluoride exceeding federal EPA drinking water limits. In 2015, a CAP consultant, Montgomery and Associates, pegged the price tag for treating and recovering Tonopah’s water at $143 million to $200 million."

" ...  the aquifer underneath the recharge basin is substantially less permeable below 300 feet than previously thought. Second, concentrations of arsenic and fluoride in natural groundwater are larger than previously estimated ..."

Lotsa good stuff in the article. Mostly sayin, Southwest USA is quite screwed.

"Over a mere four days this summer, snow from the previous winter melted into a pond of slush on Canada’s Lowell Glacier. Mauri Pelto, a glaciologist at Nichols College, called the area of water-saturated snow a “snow swamp.”

“I haven’t seen a snow swamp of this size develop this quickly ever,” said Pelto, who has spent 38 years monitoring glaciers in the region."

Not knowing what water you have got, or not got, may be even worse.

https://qz.com/1353839/theres-a-time-bomb-for-us-mexico-relations-ticking-underground/
OUT OF SIGHT, OUT OF WATER
There’s a time bomb for US-Mexico relations ticking underground

Quote
Texas and Mexico have elaborate sharing agreements for every acre-foot of water that flows through the Rio Grande, which makes sense, especially since the river is dwindling. Making sure both sides are upholding those agreements while the region rides through its regular whiplash of droughts and floods takes up most of the bandwidth of water officials on both sides.

Meanwhile, the US and Mexico barely even know about their shared groundwater. The two nations only officially recognize four cross-border aquifers (pdf). But Rosario Sanchez, a Texas A&M University hydrologist who has spent her academic life seeking out transboundary aquifers that aren’t yet on maps, has identified 36. Of those, 15 are shared between Texas and Mexico.
“Compared to the issues of illegal immigration, drug violence, economic trade, and other border and non-border issues, groundwater management ranks relatively low among the priorities of both federal governments,” wrote Gabriel Eckstein, a water-law scholar at Texas A&M School of Law, in a 2012 paper (pdf). “As a result, the [Rio Grande Valley region’s] groundwater resources are being overexploited on both frontiers as populations and industries pump with little regard for sustainability or transboundary consequences…. Ultimately, the viability of the region’s communities, natural environment, and economic growth are threatened with stagnation and may falter. And no one, at least on the federal level, is doing anything about it.”

Earth Is 'Missing' at Least 20 Ft of Sea Level Rise. Antarctica Could Be The Time Bomb

Some researchers, including DeConto, think they have found a key process - called marine ice cliff collapse - that can release a lot of sea level rise from West Antarctica in a hurry.

But they're being challenged by another group, whose members suspect the changes in the past were slow - and will be again.

'Grandfather of Climate Science' and populariser of 'global warming' Wallace Smith Broecker dies aged 87

The Columbia professor's work warned the world about the "devastating" impacts of climate change as far back as the 1970s.

As far back as 1984, Professor Broecker told a House of Representatives subcommittee that urgent action was required to stop the build-up of greenhouse gasses in the atmosphere because the climate system could "jump abruptly from one state to another" with "devastating effects".

Can´t find a good thread for this one so i will stick it here.

Vast record of past climate fluctuations now available thanks to laser imaging of shells

Refined techniques for laser imaging of shell growth rings are tapping into previously hidden data of marine climate change; by examining human and ecological responses to those changes, we learn more about what to expect from climate change in the future

Shellfish played a significant role in the diet of prehistoric coastal populations, providing valuable nutrients. They are a common find in archaeological sites all over the world, usually in huge numbers, and researchers have long explored how they could be used to make inferences about the environments that humans experienced at those locations in the past. However, although techniques were developed to infer valuable climate-related information from shells, it was previously too expensive to analyse them on a scale beyond individual and isolated records. The current study by an international team of researchers, led by the Institute of Electronic Structure and Laser (Heraklion, Greece) and the School of Geography (Melbourne, Australia) and published in Scientific Reports, presents a technique to use rapid laser imaging to increase the number of analysed shell records to previously unknown scales, and thereby greatly expand the time periods and accuracy of the reconstructed records.

Shells are a common find in archaeological coastal sites of the last 160,000 years

The present study aimed to test a new method by analysing modern shells for which there was known climate data. The researchers used modern limpet shells from across the Mediterranean, comparing records from nine different sites in Greece, Libya, Tunisia, Croatia, Malta, Turkey and Israel. By testing their methods on modern shells against known records, the researchers were able to fine-tune their calibrations and ensure that their techniques would accurately reproduce the climate changes experienced by the molluscs while they were growing. Once perfected, the method could then be used to reconstruct past climate fluctuations.

Using LIBS (Laser Induced Breakdown Spectroscopy), the researchers built a modern baseline of how marine temperatures are reflected in the elemental composition of mollusc growth rings. Previous research was unable to find consistent correlations between the two. Only the 2D imaging of whole shells provided the necessary amount of data to navigate the individual shell records, a task where the speed and low cost of LIBS exceed other techniques.

...

New technique allows large-scale reconstructions of climate that people directly experienced at a seasonal level

"We were never able to look at more than a dozen or so well-analysed shell records before, which is far from ideal given that the climatic data can vary a lot from one shell to another. To be able to compare hundreds or a thousand shells is a game changer for climate modelling," states Hausmann.

The techniques developed in the current study have far reaching implications. As a start, researchers focused on the well-known limpet shells of the Mediterranean, but preliminary unpublished results suggest that other limpet species from archaeological sites in the Atlantic and Pacific might be similarly well-suited for use with LIBS, and could provide the means for producing global climate models with seasonal resolution.

"Archaeological shell collections are heavy and a pain to store, so I hope that archaeologists and museums haven't thrown away their old boxes of shells - we now desperately want to analyse them."

DeSmog published a story this week from the Climate Investigations Center that touches on an interesting angle that’s emerging in the climate world as kids lead the way.

The article describes a conference last month at Brown University that featured a 90-minute panel built around a recent study in Nature Climate Change showing how decades of concerted misinformation played a key role in the current climate of climate denial. The event was convened by Brown’s Climate Development Lab. Brown students at the lab recently compiled and published a report giving the backstory on a dozen climate denial coalitions.

Some are long gone, like the Global Climate Coalition, others are still very much alive, like the Cooler Heads Coalition, which counts Trump advisors Myron Ebell and Steve Milloy among its members.

But even some of the ones that are no longer operational, like the Information Council on the Environment, which was funded by the Western Fuels Association and the Edison Electric Institute, still impact the current discourse.

For example, ICE’s Pat Michaels and Sherwood Idso have both gone on to a long and lucrative fossil-fuel-funded denial career. ICE’s initial PR campaign goal to “reposition global warming as theory (not fact)” is at the core of President Trump’s ongoing attempts to attack climate science with a “red team” of deniers drawn from these sorts of coalitions.

...

As pundits and deniers increasingly chide children for daring to speak out about the state of our planet, remember that these kids are speaking out against a misinformation machine that’s older than they are. For the students who put together this report, the fact that there’s a well-funded, widespread propaganda effort to protect polluters at the public expense isn’t some new revelation–it’s simply a fact of life.

Just like how no one born since February 1985 has ever experienced a month in which the global temperature has dipped below the 20th century average, this report shows that no one under 30 has lived in a world free from the fossil fuel industry’s misinformation campaign.

MIT Scientists Think The Last 3 Ice Ages Were Triggered by Tectonic Collisions

What's likely to have happened, the new study says, is these massive collisions pushed oceanic rocks up above the surface, into hot and humid tropical environments where they began to pull carbon dioxide out of the air. Given enough time, these chemical reactions could cool global temperatures and start an ice age.

The findings are based initially on an analysis of two sutures in the Himalayas – major fault zones where oceanic and continental plates have collided. Both sutures were originally formed near the equator, 50 million and 80 million years ago respectively, and happened just before major global cooling events.

"We think that arc-continent collisions at low latitudes are the trigger for global cooling," says one of the team, Oliver Jagoutz from the Massachusetts Institute of Technology (MIT).

"This could occur over 1-5 million square kilometres [0.4-1.9 square miles], which sounds like a lot. But in reality, it's a very thin strip of Earth, sitting in the right location, that can change the global climate."

...

Specifically in this case, it's the calcium and magnesium in the newly exposed rock that reacts with the carbon dioxide in the atmosphere and pulls it out of the air.

Adding the new research to previous work, the researchers were able to model the eruption and movement of more sutures even further back through time.

They found three major periods of suture formation that coincided with ice ages – in the Late Ordovician period (455-440 million years ago), the Permo-Carboniferous period (335-280 million years ago), and the Cenozoic period (35 million years ago to the present day). No sutures meant no ice ages.

"We found that every time there was a peak in the suture zone in the tropics, there was a glaciation event," says Jagoutz. "So every time you get, say, 10,000 kilometres [6,214 miles] of sutures in the tropics, you get an ice age."

The current cooler period we're technically in from a 'big picture' perspective – despite the rapid warming we've managed to bring about over the last hundred years or so – may have been caused by a major suture zone active today in Indonesia, according to the team.

I just posted the following article "Another Idiotic Global Warming Post on Townhall Authored by Matt Vespa".

Much thanks to Gerontocrat for his daily posting of charts, as I copied and pasted the Sea Ice Extent chart from his most recent post.
