Canada's #5G rollout

"A larger number of connected devices will result in huge increases in data that need to be stored in energy-intensive #data centres, which are expected to emit more #carbon than the international #aviation industry."

"It also means an exponential increase in the # of wireless networks, which are energy-guzzlers (est. to be 10x less efficient than wired networks). In 2015 alone, the energy used to power wireless networks generated approx. 30 megatonnes of carbon, the same as 4.9 million cars."
"There are no published long-term studies... As one US Senator put it, w/ #5G, “we’re kind of flying blind here, as far as #health & #safety is concerned.” For this reason, 273 #scientists & #doctors in the EU have signed a declaration calling for all 5G [] to be stopped."

#WWF storytelling as they #greenwash corporate #plunder & bear responsibility for the displacement, torture & murder of #Indigenous peoples:

"Building a sustainable & equitable future. For nature. For you."

Reality: "The financialization of #nature"
To obtain the required social license, the ruling class devised a strategy. A corporate campaign that would harness the momentum of the youth - to achieve the ruling class objectives & desired goals. #NewDealForNature

THREAD: What happens to #carbon once it's sequestered in soils? How can we lock it in & ensure it doesn't return to the atmosphere as CO2?

Soil scientists use "fractionation" methods for that^. Fractionation tells us about different pools of C-some stay forever & some are quick
Consider it like food for the body.

Some of the energy in your food will get used to build your bones-it stays there & is permanent. Some of the energy gets digested & respired as CO2 when you breathe. Not permanent, but you still need it. & some is intermediate-stored as fat.
In soils, we call the permanent fraction MAOM (minerally associated organic matter). This is the soil C that gets stuck to minerals & stays forever.

The faster fraction is called POM (particulate organic matter). This pool is a lot more dynamic

Hello all! It's #BlackBotanistsWeek and today, I'd like to share my love for plants by telling you a story about why I chose to study tree responses to #climatechange and how I go about doing so 🌿🍃 #BlackPlantLove 1/10 Image
Years ago, when I was a first year graduate student at @ColumbiaGSAS @LamontEarth, I read about the pressures organisms are facing when it comes to climate change, such as increased air temperatures, changes in precipitation, more extreme weather events, etc. 🌿2/10
In response to persistent climatic changes over the last century, most organisms have shifted their range distributions and even their abundances within their range. The ability to migrate to suitable habitat is much easier for mobile organisms. 🍃3/10

Simply planting trees is not enough. To provide a solution to the climate crisis and alleviate poverty, it is essential to take a holistic approach to tree growing that is driven by local experts and the communities that depend on the trees for survival. bbc.co.uk/news/science-e…
At TREE AID, we not only work in partnership with communities to grow trees that support the local environment and restore degraded land, we also ensure that communities have the access and tools they need to manage and protect their forests, now and in the future.
We plant on degraded and carbon poor soils, ensuring a diverse mix of tree species that provide both short and long term benefits to people and the environment.

NEW ARTICLE ALERT with examples of #consumption options with high potential to reduce #carbon footprints. Here are some of the top options and their mitigation ranges and a link to the article (tinyurl.com/tyk67kb). It is openly available @IOPscience ERL /trd Image
Super co-author team: @j_r_barrett @WiedenhoferD @biljana_macura Max Callaghan and @efesce . Some of the highlights are already covered by the Nature team (nature.com/articles/d4158…). /1
There is an obvious need to reduce greenhouse gas emissions to limit climate change. Relying strongly on consumption reduction is not only the least risky option to stay within planetary boundaries, but also absolutely necessary where incomes are high! /2

Since I've not been paid or replied to, I am declassifying. One of the biggest hurdles in building high speed rail is paying for the project. The solution is built in from the beginning. Its not just that you build it, its how you build it.

Right after hurricane Harvey Texas was flooded and I was talking about how the maglev would still be running because it was elevated. All you need to do is make it to the terminal. Thats when Trump declared National emergency and classified my work under nuclear preparedness.
Imagine a bridge, that instead of crossing the highway, runs lengthwise. It's elevated so it doesn't get in the way of animals or humans. It never stops, it never slows. Because it is elevated, accidents are almost unheard of. Making emergency evacuation safe and quick.

Healthy #soil sequesters #carbon, promotes the growth of nutrient-dense crops, holds more #water, and fights disease. What #farming practices can get you there? A thread:
Cover crops 🌿 When fields are bare, they're vulnerable to #erosion and #nutrient loss. Planting cover crops protects against this, while also smothering weeds, controlling pests, retaining #water, and enhancing #biodiversity.
Crop rotation 🔄 By refusing to plant the same #crop over and over, #farmers can return nutrients to the #soil without synthetic inputs. Crop rotation also wards off pests and disease, which have a harder time adapting with constantly-changing crops.

When an economist writes on the fudging of Forest survey data, it is an indication of a situation having gone from bad to worse. However, Ajit Ninan also falls into the trap of assessing ‘forests’ as land with tree growth. ⁦@moefcc⁩ ⁦1/n deccanherald.com/opinion/panora…

🚜🌎💚 Land use, #farming & how this impacts on #ClimateChange is under scrutiny

Today, the Committee on Climate Change (@thecccuk) have launched their new Land Use report

What does it say, does it focus on the right things and is it ambitious enough? ow.ly/HSDC50y2HXK
@theCCCuk @UKSustain @SoilsAlliance @SusFoodTrust @LandworkersUK @FOLUCoalition @GreenerUK_ @GreenAllianceUK @WCL_News @DefraGovUK @NFUtweets The report comes at a time when #farming, #landuse and its impact on #climatechange is under the spotlight like never before.

This @theCCCuk report will be a major influence on what farmers will be rewarded for doing to adapt to climate change. ow.ly/HSDC50y2HXK
Nature must be given equal emphasis in shaping the future of post-#Brexit #farm support, as #farming and #landuse is also the primary driver of global #insect decline and the #biodiversity crash.

Happy #NewYearsEve everybody! 2019 has been a record breaking year for GB electricity. Here's why...1/5

✅ Record levels of #solar power 🌞

9550MW on May 14th - the equivalent of approx 1.9 million 5W LED light bulbs 💡💡💡💡
2/5 ✅ Record #wind power 💨 - 16873MW on Dec 10th at the tail end of #stormatiyah

Wind supplied almost 44% of #electricity over the day as a whole.
3/5 ✅ Record number of #coal free days 🔥 - the longest period without burning coal to produce electricity since the Industrial Revolution! @PastCoal

What's our #beef with beef?

Public interest on #climate, #biodiversity & #diet is rightly growing

#Meat is often at the heart of the debate but it's important we look past headlines & unpick the detail

THREAD 👇

#EatBetterMeat #EatOrganic #BBCOne 👉ow.ly/MjQ150xjJI9
Our #meat comes from different #farm systems

When animals are grazed on grass, as in #organic, this can have positive impacts on #climate & #nature. Intensively produced #grain-fed chicken & pigs can have the opposite effect

#EatBetterMeat #EatOrganic 👉ow.ly/MjQ150xjJI9
🐄🐖🐔 Intensively farmed animals are almost always fed on #grain & imported #soya

The production of animal feed can exhaust soils and drive #rainforest clearance

This is devastating for the #climate & #biodiversity

1/15: [THREAD] Unpacking the Headlines:
20 GW of #NuclearPower planned in India by 2030

2 ways to analyze:
1)Can it happen - and should it happen?
2)What’s nuclear’s role, and what’s special/different about India?

I combine both aspects in this thread
2/15: The plans tick many of the right boxes – standardized designs, fleets, etc. There is also talk of encouraging the private sector – but will they bite? Global private sector is even harder given #DifferencesOfOpinion on the nuclear liability bill.
3/15: Nuclear has many concerns for different people – fuel disposal, accidents, proliferation, etc. Latter is a non-issue as India is a proven mature actor, and it also can island safeguard civilian reactors. But what about the economics? Esp. fully loaded costs.

The German government unveiled a major policy package to combat #climate change. The subsequent discussion in the German media shows the huge political and economic cost of a simple-minded focus on #carbon pricing – it’s the 1980s all over again! A Thread @BMF_Bund @JWMason1
The policy package contains a mix of mainly sensible measures: A slowly increasing carbon price, public investment (public trains), subsidies for switching to green technology, transfers to compensate “losers”, and a plan to move out of coal energy.
What happened in the subsequent media discussion is very interesting. As expected, there was critique of certain transfers and subsidies that some groups did not like (“waste of money”). Also, the opposition parties were critical – no surprise here.

I am more pissed off at this premise from the audience (a teacher!) than with #BernieSanders' response
"Human population growth has more than doubled in the past 50 years. The planet cannot sustain this growth."
washingtonpost.com/politics/2019/…
Of course the population has grown! But,
a. #sustainability in the context of #ClimateChange is NOT about sheer numbers of people
b. the growth rate has slowed down. A LOT!
Therefore, discussing #abortion is awful in this context
Take the important #abortion question (pro or anti) to some other context of the human condition. Don't thread that with population growth and sustainability
Do people even care about evidence anymore?

Ok, so a bit of a nerdy thread coming up, using Fujian province’s ETS to illustrate what’s so wrong with China’s pilot #carbon markets. #OCTT
I’m using Fujian in this thread, but many of the other pilot markets have the same problem. It should sound alarm bells in Beijing setting up the national carbon market and also for foreign companies eager to trade Chinese carbon.
After some small-scale trading in Fujian after last year’s compliance deadline, the local carbon permits went unchanged and untraded at 29.70 yuan from Nov. 28 last year until Mar. 8 this year.

Over 10 years ago, @ChemistryWorld started a project with the @NakedScientists (especially @Meera_Senthi) to tell the story of each chemical #element: The Chemistry in its Element #podcast. Let's look back for #IYPT2019. Here's @brianclegg with #hydrogen:

chemistryworld.com/podcasts/hydro…
@ChemistryWorld @NakedScientists @Meera_Senthi @brianclegg The podcasts weren't published in atomic number order – we jumped around the #periodictable a bit – but here's @peterwothers getting grumpy about party balloons and the loss of the precious elemental resource: #Helium

#Lithium lubricates bearings & boosts batteries, but is also an important drug for depression and bipolar disorder. Nirvana sang about it in 1990 and, hot on their heels, Matt Wilkinson wrote a #podcast for @ChemistryWorld in 2009: chemistryworld.com/podcasts/lithi… #IYPT2019 #Mendeleev

This is such bull***t.

First it was a hoax.

Then the science was uncertain.

Then we were “alarmists.”

Then any fix was too expensive.

Now it will be fixed with “innovation.”

thehill.com/policy/energy-…
As the truth emerges, they just fall back to a more credible trench to defend the same industry and its same smelly lies and big fat subsidy.

Give me a break.

Want “innovation”?

Put a #priceoncarbon, so you can reward investors in #carbon reduction;

Strip this crooked industry of its $700 billon/yr subsidy (just in US, per @IMFNews);

I must respectfully disagree with my friend @SenJohnBarrasso ’s Op-Ed on the @nytimes.

I will explain why in this thread⬇️ nytimes.com/2018/12/18/opi…
1️⃣ The referendum result in Washington State looked like more relentless campaigning by the fossil fuel industry against #climate action;

without that industry onslaught, the #carbontax referendum there would probably have passed.

nytimes.com/2018/12/30/opi…
2️⃣ A #carbontax is not “expensive,” as in our proposals all the money goes back to the public.

Taxing #carbon moves energy markets toward cheaper renewables.
On balance, people save money.

Don’t forget that the savings from avoiding #climate catastrophes are immense.
