Google is cracking down on digital ads that promote the idea that climate change is a hoax or make money from that kind of content, hoping to limit revenue for climate change deniers and stop the spread of misinformation on its platforms.

The company said in a blog post on Thursday, Oct. 7 that the new policy will also apply to YouTube, which last week announced a sweeping crackdown of vaccine misinformation.

Rough back of envelope calc. It would take Canada 1/3 of all its electrical production to offset its 2019 Carbon emissions. That is if all energy inputs are being captured here, which my spidey sense says no.

C+O2 --> CO2 yields 393 kJ/mol CO2 = 32 130 kWh per tonne of CO2 which is the minimum you'd need to put IN to reverse the reaction per the 1st law.

C and O2 have heats of formation of 0 at STP because they are elements. CO2 heat of formation is -393 kJ/mol. /44g per mol x 1000 g/kg ×1000 kg/T /1000 kJ/MJ / 0.28 kWh/MJ

Manabe extends this result to predict a temperature increase by 2000 of 0.8ºC based on a 25% increase in CO2, which was pretty close.

So I just asked a chemical process engineer friend what the energy output of a tonne of CO2 is

C+O2 --> CO2 yields 393 kJ/mol CO2 = 32 130 kWh per tonne of CO2 which is the minimum you'd need to put IN to reverse the reaction per the 1st law.

C and O2 have heats of formation of 0 at STP because they are elements. CO2 heat of formation is -393 kJ/mol. /44g per mol x 1000 g/kg ×1000 kg/T /1000 kJ/MJ / 0.28 kWh/MJ

I don’t know where they get the 230kWh figure from. They’re short about 32,000 kWh

Edit: Oops got it wrong 2411 kWh. They’re out by a factor of ten.

"When we add nitrogen from air to the slurry, it changes the environment to stop methanogenesis basically. So it drops the pH down to just below six and we're catching that early. So it stops the breakdown of those methane microbes that then release the gas to the air," Puttick said, adding their patented technology is the only one of its kind.
What comes out of the machine is an odorless brown liquid, called NEO -- a Nitrogen Enriched Organic fertilizer.
According to N2, their NEO has double the nitrogen content of regular nitrogen fertilizer; one of the most commonly used fertilizers to boost production of corn, canola and other crops.
Puttick said independent tests showed their technology reduces methane emissions from slurry by 99%. It also cuts by 95% the emission of ammonia; described by the EU as one of the main sources of health-damaging air pollution.
On a 200-cow dairy farm this equates to "a reduction of 199 tons of carbon equivalent every year with one machine," said Puttick, adding that they're now looking to scale out the technology across the UK livestock sector, and have recently installed it at a pig farm

"Just to give you some perspective — 20 million tonnes of CO2 — this is the annual carbon footprint of countries like Estonia, Croatia, or Bulgaria," says Jürgen Knödlseder, an astronomer at IRAP, an astrophysics laboratory in France.

"Some of our colleagues are a bit shocked by this idea," says Tibaldo. "What we really think is that these options must be on the table. The emergency we are facing is so big and clearly we are playing a role in it with our work."

The astronomers hope that other scientific fields will be inspired to take a similar global inventory of the greenhouse gas emissions from their research infrastructure. "As far as I know," says Knödlseder, "this is the first time that this kind of study has been done for any research field."

Australia’s coal export boom forecast to end abruptly amid big drop in demand from China

Study finds Chinese consumption will fall within two to three years as Australian coalmining communities warned to reduce dependence on industry

Australia’s coal export boom will come to an abrupt end because of an “imminent and substantial” drop in purchases by China, and local coalmining communities should brace for the change, the lead author of a new study says.

The peer-reviewed paper, published on Thursday in the journal Joule, forecasts China’s thermal coal imports will contract at least a quarter from 2019 levels of 210m tonnes by 2025, mostly as improved transport links will give local suppliers an edge.

If China pursues more ambitious efforts to cut carbon emissions, the decline will be almost twice as fast, with imports sinking to 115m tonnes by 2025. Shipments of coking coal used in steelmaking face a similar downward trajectory, the researchers found.

The study used satellite and other data sources to compile a more detailed picture of individual power and steel plant coal demand. It also analysed how new transport links have expanded supplies from inland Chinese provinces and Mongolia to coastal users, supplanting Australian and Indonesian exporters.

“This was actually somewhat of a surprising outcome for us,” said Jorrit Gosens, a researcher at the Australian National University’s Crawford School of Public Policy and the report’s lead author.

“China reducing imports of thermal coal and coking coal by roughly a quarter over the next five years, that’s a major drop and not something that is far off into the future.”

As growing climate change impacts are experienced across the globe, the message that greenhouse gas emissions must fall is unambiguous. Yet the Emissions Gap Report 2022: The Closing Window – Climate crisis calls for rapid transformation of societies finds that the international community is falling far short of the Paris goals, with no credible pathway to 1.5°C in place.

"Global GHG emissions in 2030 associated with the implementation of nationally determined contributions (NDCs) announced prior to COP26 would make it likely that warming will exceed 1.5°C during the 21st century. Likely limiting warming to below 2°C would then rely on a rapid acceleration of mitigation efforts after 2030. Policies implemented by the end of 2020 are projected to result in higher global GHG emissions than those implied by NDCs. (high confidence)."
