‘Collapse of Civilisation is the Most Likely Outcome’: Top Climate Scientists - Resilience
Australia’s top climate scientist says “we are already deep into the trajectory towards collapse” of civilisation, which may now be inevitable because 9 of the 15 known global climate tipping points that regulate the state of the planet have been activated.
Australian National University emeritus professor Will Steffen (pictured) told Voice of Action that there was already a chance we have triggered a “global tipping cascade” that would take us to a less habitable “Hothouse Earth” climate, regardless of whether we reduced emissions.
Steffen says it would take 30 years at best (more likely 40-60 years) to transition to net zero emissions, but when it comes to tipping points such as Arctic sea ice we could have already run out of time.
Evidence shows we will also lose control of the tipping points for the Amazon rainforest, the West Antarctic ice sheet, and the Greenland ice sheet in much less time than it’s going to take us to get to net zero emissions, Steffen says.

I have included data and I think many folks won't look at it since they know it won't agree with what they think.

This article is mandatory reading regarding the Navajo nation decision to buy coal mines
The Navajo Wanted To Go Green, Then This Surprise Deal Made Them America’s Third-Largest Coal Miner
It is a great example of upside down, backwards reporting that gets it completely wrong.
The writer thinks that NTEC went wrong by buying coal mines off the reservation. The fundamental error was in buying into coal -- period. That NTEC assumed clean-up and pollution liabilities is just criminal negligence by NTEC.
I worked on the Navajo Reservation for ~ 5 years and tried to tell them that buying coal mines was idiotic but no one listened. They thought they were insuring employment and cutting out the middle-man. Now they have a mountain of coal no one wants and a massive remediation in their future. The nation is going to pay for Navajo Nation leader stupidity, NTEC corruption and short term decisions that will bite them for another generation.

US Stimulus Strategy: Recommendations for a Zero-Carbon Economic Recovery - Rocky Mountain Institute
This report outlines RMI’s recommendations for four key programs that US policymakers can use to jumpstart the economy, address equity, and advance a low- or zero-carbon future for the United States:
This report outlines RMI’s recommendations for four key programs that US policymakers can use to jumpstart the economy, address equity, and advance a low- or zero-carbon future for the United States:
- Build Back Better Buildings: A building retrofit program to catalyze residential and commercial building improvements at an unprecedented scale.
- Enhance Access and Electrify Mobility: Investment to prioritize pedestrians, cyclists, and public transit over the automobile, while also supporting the growth of the electric vehicle market.
- Debt Forgiveness for a Sustainable Recovery: A financial incentive program to provide companies with debt relief based on verifiable emissions reductions.
- Economic Recovery Facility for Financing Low- and Zero-Carbon Activities: A federal entity dedicated to facilitating the financing of clean energy and infrastructure projects.

Translated:
Pay companies for making short sighted, publicly detrimental decisions in the past. Turn pollution into a cash cow meted out by politicians.
While I understand the reasoning -- accelerate the transition to renewable energy -- the unintended side effects as noted above are .... difficult to swallow. A carbon tax makes a lot more sense to me

Familiar Culprit May Have Caused Mysterious Mass Extinction
Now he and David Bond of the University of Hull in England say they have cracked the case in a study published last month in the journal Geology. Widespread volcanic eruptions unleashed enough carbon dioxide to heat up the planet and trigger two pulses of extinction separated by 1 million years, they report. If true, it places the first grand wipeout of life on Earth in good company: Many of the other major mass extinctions are also thought to be victims of global warming.

In the Midst of the Coronavirus, California Weighs Diesel Regulations
Communities that live in the shadow of industry are hit hard by pollution, and by Covid-19. But companies are using the pandemic to try to delay stricter rules.

Climate crisis to blame for $67bn of Hurricane Harvey damage – study
Climate crisis to blame for $67bn of Hurricane Harvey damage – study
At least $67bn of the damage caused by Hurricane Harvey in 2017 can be attributed directly to climate breakdown, according to research that could lead to a radical reassessment of the costs of damage from extreme weather.
Harvey ripped through the Caribbean and the US states of Texas and Louisiana, causing at least $90bn of damage to property and livelihoods, and killing scores of people.

Climate worst-case scenarios may not go far enough, cloud data shows
Modelling suggests climate is considerably more sensitive to carbon emissions than thought
Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds, scientists have said.
Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts said the projections had the potential to be “incredibly alarming”, though they stressed further research would be needed to validate the new numbers.

Fast-growing mini-forests spring up in Europe to aid climate
Fast-growing mini-forests spring up in Europe to aid climate
Scientists say such ecosystems are key to meeting climate goals, estimating that natural forests can store 40 times more carbon than single-species plantations. The Miyawaki forests are designed to regenerate land in far less time than the 70-plus years it takes a forest to recover on its own.
Advocates for the method say the miniature forests grow 10 times faster and become 30 times denser and 100 times more biodiverse than those planted by conventional methods. This result is achieved by planting saplings close together, three per square metre, using native varieties adapted to local conditions. A wide variety of species – ideally 30 or more – are planted to recreate the layers of a natural forest.

Oil spill caused by melting permafrost tied to Russian arctic emergency
Melting permafrost caused a fuel tank holding 21,000 tons of diesel oil to collapse in Russia's Arctic Circle, leading to a 135-square mile oil spill.

A War Against Climate Science, Waged by Washington’s Rank and File
WASHINGTON — Efforts to undermine climate change science in the federal government, once orchestrated largely by President Trump’s political appointees, are now increasingly driven by midlevel managers trying to protect their jobs and budgets and wary of the scrutiny of senior officials, according to interviews and newly revealed reports and surveys.

So what's wrong with this data on weather related events. https://www.jpands.org/vol14no4/goklany.pdf
Do everything printed in the Guardian is gold. Give me a break.
This is the video which basically says that as you get close to 100% wind and solar it gets costly because you must maintain reliable backup power.
I'm sure many of you didn't look at it because of the title "What's Wrong with Wind and Solar. In fact some actually stated that they didn't look at it. It doesn't say wind and solar are bad it just points out the reliability issue is eventually costly. As and example PG&E just sent me notice that they are changing my EV rate plan to EV2A. The reason is that there is know excess solar during the day. This has the affect of cutting my solar savings by about $1,500 per year.
Kind of goes along with the misleading Michael Movie misleading movie bashing renewables arguing that more is not the solution, key is reducing consumption (like adding more insulation is better than adding rooftop solar).
