*To date, most studies have focused on understanding how much carbon is stored above ground (in trees and other plants, for example). This research, however, revealed that when you look below ground and get into deeper levels of soil, there are massive deposits of carbon.*

Canada’s first-ever national carbon map reveals the location of billions — yes, billions — of tonnes of carbon stored in ecosystems across the country. This data, and how we use it, could alter the pace of climate change.

Over the span of two years, researchers fed data from existing soil samples collected from across the country, as well as long-term satellite data and topographic and climate variables, into a machine-learning algorithm. Researchers were able to estimate carbon at a 250-metre spatial resolution in different carbon pools (soils and plant biomass), as well as at multiple depths (1−2 metres).

Tens of thousands of field measurements were fed into a machine-learning algorithm to train satellite observations, including space-based laser scanning data, to estimate carbon stocks in plant biomass and soils across Canada. The resulting national carbon map will have a huge impact on the way conservation activities and policies are approached to prioritize nature-based climate solutions.

## ORIGINAL PAPER

Large soil carbon storage in terrestrial ecosystems of Canada

https://www.essoar.org/doi/10.1002/essoar.10507117.

Abstract

Terrestrial ecosystems of Canada store a large amount of organic carbon © in soils, peats and plant materials, yet little is known about the C stock size and distributions, both spatially and in various C pools. As temperature rises, C is becoming available for disturbance, decomposition and eventual release into the atmosphere, which makes the quantification of C stocks in terrestrial ecosystems of Canada of high interest for the assessment of climate change impacts and conservation efforts. We used a large number of field measurements, multi source satellite, climate and topographic data and a machine learning algorithm to produce the first wall-to-wall estimates of C stocks and uncertainties in plants and soils of Canada at 250 m spatial resolution. Our findings show that above and below ground live biomass and detritus store a total of 21.1 Pg C. Whereas the Canadian soils store 384 (& plus mn; 214 90% confidence interval) Pg organic C in the top 1 m, 92 Pg C of which are stored in peatlands, confirming that the soil organic C dominates terrestrial carbon stocks in Canada. We also find previously under-reported large soil organic C stocks in forested peatlands on the boreal shields of Canada. Given that Canada is warming twice the global average rate and Canadian soils store approximately 25% of world soil C stocks in top 1 m, initiatives to understand their vulnerabilities to climate change and disturbance are indispensable not only for Canada but also for the global C budget and cycle.

With 145,000 panels.

The world’s largest floating solar farm has now begun operations at the Sirindhorn Dam on the Lam Dom Noi River in Thailand. The dam has a capacity of generating 45MW of power using its solar panels, the Electricity Generating Authority of Thailand (EGAT) confirmed in a press release.

The news comes after the country started advancing its carbon neutrality goals by 15 years. At the United Nations Climate Change Conference being held in Glasgow, UK, Thai Prime Minister Prayut Chan-o-cha pledged that his country would attain carbon neutrality by 2,050 much ahead of the earlier set target date of 2,065 local media reported. The announcement is a major move considering that two-thirds of Thailand’s current power generation is sourced from natural gas.

Carbon is not our enemy, but the system is out of balance. Too much as atmospheric gases and too little in the ground and soil in the simplest terms.

Biochar, although not new, has found a new lease of life. A process that generates heat, uses waste, locks away carbon and benefits almost every system to which it is introduced.

After reading it all about it, I just had to share the possibilities and so I compiled what I learnt into a short video for those interested.

Hope you enjoy and have a great day.

Biochar Carbon Capture And Storage.

Carbon is not our enemy.

As an element it forms the basis of life as we see it all around us but we have for too long squandered valuable resources with no respect for their true value, but that can change.

It almost seems too good to be true, to be able to combat climate change whilst getting better yields and reducing flooding and land degradation, and increasing cheap access to drinking water.

Well just watch this.

Why not see some other ways we can make tomorrow better by watching this next, These could be the golden years.

With a minimalistic design and H-shaped front panel, the new mtu hydrogen fuel cell is a complete solution for power supply in the megawatt range that will be produced in series from 2025. This modern-looking module will in the future deliver a net power output of around 150 kW – sufficient to power approximately ten homes. It can also be connected together into scalable fuel cell power plants with outputs in the megawatt range – capable of providing clean backup power for large data centers.

The fuel cell module is the result of collaboration between Rolls-Royce and cellcentric, a joint venture company set up by Daimler Truck AG and Volvo Group AB earlier this year. It is based on cellcentric’s fuel cell modules that emit nothing other than water vapor. This will enable CO2-free, climate-neutral generation of emergency power for data centers.

“Electrical generators based on fuel cells represent the next leap forward in the energy transition, both for our customers and us,” said Andreas Schell, CEO of Rolls-Royce Power Systems. “That’s why we’re investing a three-digit million amount in R&D over the next few years, and we hope that this strong commitment will encourage governments and politicians to promote and support this pioneering, extremely climate-friendly technology. When they run on green hydrogen, meaning hydrogen made using renewable energy sources, fuel cells are climate-neutral. For this reason, and also because we’re simply convinced by fuel cell technology, we also want to look into how green hydrogen can be produced cost-effectively in the quantities we need.”

The noise barriers built in Switzerland can supply up to 101 gigawatt hours of solar electricity every year. The prerequisite is that all noise barriers are covered with solar installations, as far as this is possible and economical. This would be possible with a solar capacity of 111 megawatts. This is the result of a study commissioned by the Swiss Federal Council at the instigation of Bruno Storni, a member of parliament from the Swiss Social Democratic Party.

This potential is far below what is technically feasible. However, the authors of the study subtracted the potential that would hardly be economically feasible according to the current state of the art. In addition, they had to take into account site conditions such as shading of the walls or safety aspects.

101 gigawatt hours sounds a lot. But this is only 0.15 per cent of the usable solar potential on roofs and facades used for comparison in Switzerland. For the federal road administration Astra and the Swiss Federal Railways (SBB), however, it is nevertheless a major step towards climate neutrality. After all, solar installations on noise barriers near road tunnels alone cover eleven per cent of the potential on Astra’s total surfaces.

Cutting the price of CO2 removal to under $100 per ton.

Reducing global carbon emissions can go a long way in reducing the impact of climate change, though it may not be enough.

In a bid to turn the tide around amid dire scientific predictions, the U.S. Department of Energy (DOE) announced ambitious new plans to accelerate the development of carbon capture technologies, a report from The Verge explains.

Dr. Yuval Noah Harari, macro-historian, Professor, best-selling author of “Sapiens” and “Homo Deus,” and one of the world’s most innovative and exciting thinkers, has a few hypotheses of his own on the future of humanity.

He examines what might happen to the world when old myths are coupled with new godlike technologies, such as artificial intelligence and genetic engineering.

Harari tackles into today’s most urgent issues as we move into the uncharted territory of the future.

According to Harari, we are probably one of the last generation of homo sapiens. Within a century earth will be dominated from entities that are not even human, intelligent species that are barely biological. Harari suggests the possibility that humans are algorithms, and as such Homo sapiens may not be dominant in a universe where big data becomes a paradigm.
Robots and AI will most likely replace us in our jobs once they become intelligent enough.

Although he is hopeful that AI might help us solve many problems, such as healthcare, climate change, poverty, overpopulation etc, he cautions about the possibility of an AI arms race.

Furthermore Dr. Yuval Noah Harari suggests this technology will also allow us to upgrade our brains and nervous systems. For example, humans will be able to connect their minds directly to the internet via brain implants.

The dramatic rise of online learning during the COVID-19 pandemic has spotlit concerns about the role of technology in exam surveillance — and also in student cheating.

Some universities have reported more cheating during the pandemic, and such concerns are unfolding in a climate where technologies that allow for the automation of writing continue to improve.

Over the past two years, the ability of artificial intelligence to generate writing has leapt forward significantly, particularly with the development of what’s known as the language generator GPT-3. With this, companies such as Google, Microsoft, and NVIDIA can now produce “human-like” text.

ZipCharge has launched a new type of charging product for EVs that might be able to convince people worried about range anxiety to switch from gas vehicles. The British startup has introduced a powerbank for EVs called ZipCharge Go at the Cop26 climate summit. It’s about the size of a suitcase and weighs around 50 pounds — plus, it has wheels and a retractable handle, so users can put it in their trunk and easily take it out when they need to charge.

According to the company, the Go can provide up 20 miles of range after being plugged into the car for 30 minutes. A higher capacity version will be able to provide an EV up to 40 miles of range. The device works with any plug-in hybrid or EV with a Type 2 socket, and it can charge that vehicle to its full capacity between 30 minutes to an hour. Charging up the device itself is as easy as plugging it into any socket, and users will be able to control and monitor it through an app, where they can schedule future charges during off-peak hours for cheaper costs.

While range anxiety is becoming less of an issue these days, it’s still keeping those on the fence from making the leap. A company called Gogoro developed hot-swappable battery technology for scooters to address the problem, but batteries in electric cars typically can’t be swapped out. SparkCharge has a portable EV charging system called the Roadie, but it’s not nearly as easy to carry around as the Go.
