A concrete idea to reduce CO2 emissions | Karen Scrivener
Take action on climate change at . Concrete is the second most-used substance on Earth (behind water), and it’s responsible for eight percent of the world’s carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement known as LC3, which could slash carbon emissions from this crucial building material…

From Prison to Purpose Through Wildland Firefighting | Royal Ramey | TED
When wildfires rage in California, incarcerated people are often on the front lines fighting the flames. TED Fellow Royal Ramey was one of them. He shares the story of how doing public service in prison inspired him to cofound the Forestry and Fire Recruitment Program, a nonprofit helping formerly incarcerated people become wildland firefighters —…

The Recipe for a Healthy Climate Starts at the Dinner Table | Anthony Myint | TED
Why aren’t restaurants part of the climate solution? This question inspired chef Anthony Myint to go from opening buzzy pop-ups to pushing for a shift to regenerative farming practices in the food system. He explains how it didn’t go the way he expected at first — and how restaurants are now teaming up with farmers…

To End Extreme Poverty, Give Cash — Not Advice | Rory Stewart | TED
Are traditional philanthropy efforts actually taking money from the poor? Former UK Member of Parliament Rory Stewart breaks down why many global development projects waste money on programs that don’t work. He advocates for a radical reversal rooted in evidence: giving unconditional cash transfers directly to those in need, a method that could unlock the…

@Christopher Brand So what is the “limited” amount you’re talking about? You must have an upper limit at which disaster strikes and the world burns, right?
Christopher Brand
March 4, 2021 at 4:43 pm
@Michael Tyler no, I don’t personally have such a limit (climate science consensus would be a good place to start). I assume that atmospheric CO2 is the “plant food” you are referring to. More broadly, agricultural fertilizer runoff is a serious pollution problem and both CO2 and fertilizer will kill plants if there is too much, to say nothing of all the affects on people. The premise that plant food can’t be bad (in any amount) is silly 🙂

Can we please stop with this CO2 emissions crap. Do the research. Demonizing CO2 is a scam and the world, particularly the western world is falling for it. The scam is getting bigger and more and more people are getting in on it but know this. When all the gas and coal fired power is gone in the west for the sake of CO2 emissions and we enter the next little ice age, who will be hurting then. Everyone! Stop this nonsense now and stop thinking were so important to the Earth’s climate. How narcissistic. The Earth’s climate has been changing for centuries with and without changes in CO2 levels so demonsing a gas, that is essential to life is just absolute stupidity.

being stuck in a concrete industry, You cant do without concrete. all it would take is someone not beholden to concrete industry, to produce another material that is stronger, weighs less and doesnt need a large carbon and water footprint. they dont “like” concrete in countries with little drinking water that concrete demands but they have no alternatives.

1) By reflecting away 30% of ISR the albedo, which would not exist w/o the atmosphere, makes the earth cooler than it would be without the atmosphere like that reflective panel set on the dash. Remove the atmosphere/GHGs and the earth becomes much like the moon, a barren rock with a 0.1 albedo, 20% more kJ/h, hot^3 on the lit side, cold^3 on the dark. Nikolov, Kramm (U of AK) and UCLA Diviner mission all tacitly agree.
2) the GHG up/down welling, “trapping”/”back” radiating/delaying/intercepting, 100 % efficient, perpetual warming loop requires “extra” energy which according to RGHE theory it gets from
3) the terrestrial surface radiating that “extra” energy as a near ideal .95 emissivity black body which
4) it cannot do because of the non-radiative heat transfer processes of the contiguous atmospheric molecules.
1+2+3+4 = 0 Greenhouse Effect + 0 Greenhouse gas warming + 0 man caused climate change.

Yeah, but if you’re heating it significantly less (using less energy = saving money) and you don’t need new equipment, it’s probably pretty affordable. I mean, it mostly sounds like the ingredients haven’t changed, it’s just the proportion of them and how they’re combined.

How about just mixing in dirt or clay and use pressure allowing 50-90% less cement to form building blocks and pillars (can still be done onsite). We need KISS solutions, not more complexity, and further importation of goods creating additional emmesions.

“20% pollution is caused by clothes production.” A fact I think everyone should know. By simply buying less clothes or just sufficient can help a lot. Thanks
Arno De Coster
March 9, 2021 at 1:42 pm
I think it has also to do with the place where the clothes are made. If you buy clothes from 10 euros, they are normally not made in good conditions. But if you buy clothes from about 50euros, you can be sure that the working conditions were already a lot better than the conditions with the cheap clothes.

CO2 is not a pollutant as such; vegetation loves it and also CO2 is actually not linked to climate warming; true (!) historical archeological data shows that there is no link between CO2 levels and average air temperature !
It is the basics of data analysis not to adjust or selectively choose results to back up the thesis, yet this is exactly what so called greenies have been doing for years, including falsifying the results;
When climate really cools down in a few coming years, then those CO2 fighters will find another false reason to fool mankind again. Earth atmosphere has been cooling down already for the last few years.
And the cooling will keep progressing, I wonder for how long they will be able to keep telling us fairy tales about warming when more and more areas will be hit with unprecedented cold weather.
It is so sad that most people on Earth got fooled by those greenies and polititians.
