Report Finds 76 Solutions Available Right Now to Slow Down Climate Change
We have all the solutions we need to avoid catastrophic warming, right now, claims a new report by Project Drawdown. And, not only are they easy to implement, they’re far cheaper than doing nothing.

’Project Drawdown’ report says we’ve already got the tech to reach negative emissions by 2040s
I’ll read the report later.
I can already think of 10 or so easy to implement tech strategies, starting with cobalt bomb. Number two would be cut down all the forests and preserve all the timber with arsenic to make room for massive forest regrowth. Number three perhaps world economic meltdown. Easy to implement is not necessarily synonymous with desirable.

I’m pretty sure you could insert the words “without disastrous consequences” between implement and tech. without changing the intended meaning.

Yes, sorry, I’m being unduly negative. There’s been a need for a holistic overview like this for 30 years.
> The review outlines three key areas: reducing emission sources, protecting and increasing the natural systems that cycle these chemicals, and how to achieve these things while simultaneously improving society. When the scientists grouped their solutions by sector, they were ranked like this:
A good start.
> nuclear power, reducing food waste and providing women with better education and access to healthcare – which empowers them to have smaller families.
I’m not sure that food waste is an issue. Almost all food ends up getting recycled in one way or another, mostly as fertiliser and animal food. But they do also address eating less – diets – which is a big one.
Technical paper at:
https://drawdown.org/sites/default/files/pdfs/Drawdown_Review_2020_march10.pdf
Here’s a weird one I hadn’t thought of. “The chemicals used in refrigeration are potent green-house gases, which often leak during use or disposal. We can better manage and dispose of the fluorinated gases currently used as refrigerants, and, ultimately, replace them with benign alternatives.” They calculate that better disposal and then replacement of refrigerants has a huge effect, 105 units, of the same order of magnitude improvement as is possible with a switch of electricity production to wind power, or solar power. That’s eight times as large as the improvement possible by switching to electric cars, and more than possible by tree planting worldwide. How true is this? This is not a CO2 related issue, so should it be included here at all?
Here are their top 24. I think their numbers need checking.
Thanks for the review moll.
I must make time to read the report.

Food waste is a huge issue because of the amount dumped into landfill. Yes a lot is left on the farm and used as animal food or eventually decomposes. There are risks with this such as disease transmission and pest populations. Organised collection for composting or methane production/fertiliser would seem the smart move.mollwollfumble said:

Why does it need to be related to CO2 simply because trees are involved?
I thought the “should it be included” an odd question as well, but the “how true is this” question seems absolutely reasonable. If refrigerants do have this huge effect, how come no-one else is talking about them?

My pet peeve is food miles. With globalisation food is shipped all over the world, sometimes to where the same product is grown/made.
No food miles here. Lucky to be food metres.

Food miles is the common term even in metricated countries.
:) I was being literal in that most of my food comes from within less than a km.

Spot on. and surrounds. Like I have heaps of edible bush tucker planted by my hand and is continued by birds and ants and all of creation. Plus I can walk and pick oranges and grapes and watermelons and even my own wheat if I wanto to tresh and grind the stuff myself.

OK. How about your coffee. Moccona coffee is grown in the West Indies. The beans are shipped to the Netherlands, processes & packaged then shipped world wide including Australia. Lotta km there.
Coffee is food?
I drink Australian grown and packed coffee.

I understand that but you are an exception. Most people don’t have that luxury.
Since most Aussies live in cities, true. The rest of us though, do have that luxury.

Me too. NQ Gold is grown near Mareeba but the supermarkets push Moccona & Nescafe.
I stay within the state. https://www.buncoffee.com.au/shop/100-australian-grown-coffee/
But I do go to South Australia for my Coopers.

I grow quite a few vegies but it’s a constant battle with the hoppies & the possums.
Fencing. Netting.
I shouldn’t get too cocky here because I have nil possums and though I have seen the odd kangaroo in the yard and even in my house one night. The roos aren’t much of a problem though one night a kangaroo startled by something while in my nursery, spun in a circle as it was escaping thus knocking over some 500 odd plants.

Possums are strong & sneaky. I nailed in mouse wire around the ceiling ventilators to keep the snakes out. Damn possums ripped it out & took up residence until I put a carpet snake up there. The possums decamped.
Like the carpet snake idea.
Mrs rb’s grandfather had one in his farm shed that was prone to drop on his shoulders they were such good friends.
A farm machinery salesman dropped in one day and as he walked into the shed, the snake dropped on him. He went back to his car got a gun out and shot it.
Old Jack wasn’t impressed and told the man to go back to the company he represented and tell them why none of their merchandise was welcome on his farm again.
>> food miles
I noticed here how the traffic has just about doubled overnight with the resumption of schools. Perhaps education isn’t that good for global warming after all.

Mostly. Most importantly, they’ve missed the fact that the residence time of some CFCs in the atmosphere is so long that we’d have to wait 100 years to see any change in atmospheric concentration even with no emissions.
One other thing that concerns me slightly about the report is that there’s not a single word in there about reducing the profligate use of electrical energy or transport.
