The planet will heal. Once we're gone

Possibly not, I read the oceans could boil off, so it would be pretty xxxxxx.

Zhenga1991, you’ve fallen for the “aaah the world is going to burn up by 2030, we all gonna die because that’s what Greta said. She has no understanding of climate or weather or history or any science discipline…but she speaks for my existential fears and negative bias…so I’ll believe her than rational thinking…yes…emotion is always the best to follow for making sensible decisions…” KoolAid. If we listened to you and the greens, it won’t be humanity through fossil fuels that’s kills us all, it’ll be genocide wrought by the Greens/commies and people with YOUR mindset. All these fears you have are only in your mind, they’re not reality. You need to snap out of it

It’s easy to plant trees 🌲. Harder to nurture a forest 🌳 which needs mushrooms 🍄 and worms 🪱 and squirrels 🐿️ and insects 🐞 and birds 🦅.

Definitely, supporting our biodiversity is key also along with predator & pest control, weed management, just to name a few

Wind and solar are not cutting it. Cost is too high, and carbon increases because we are building it, and keep on increasing as the energy demand goes up and we start replacing old turbines and solar panels. Already even in small countries like Australia, old solar panels are becoming a problem that is hidden from the people

Save Our Planet - Now

Unfortunately, globally, there are not the resources, metals, minerals or fossil fuel, to replace fossil fuels with alternative low emissions energy production. In particular fertilisers are already in short supply. The one truth in economics: Supply will meet the demand that has the ability to pay. Far too many do not have the ability to pay. Depletion means global supply of fossil fuel are near permanently declining supply and rising real cost.

[@clive373]

I do believe you are close to the truth. 40 years ago people told me we would make the transition when oil got too expensive. I thought, why wait until transition is too expensive???

[@dan2304]

@@clive373 Unfortunately the technology was not up to the task when we needed to move to low emissions 40 years ago. Now globally in complete overshoot, a very serious depression, famine and economic and population decline are almost unavoidable. It depends on just how badly it is mismanaged. Global warming and sea level rise will only exacerbate as fossil fuels are used to depletion.

@ Dan, you wrote, "Supply will meet the demand that has the ability to pay. Far too many do not have the ability to pay." Economists were idiots to assert this as if we had nothing to worry about, unless they meant that when the sup[ly is short the price will double and triple,. So, most will be unable to pay. So, we took it to mean the supply will grow to meet the demand, when it turns out that the demand (with the money) will fall to match the supply. We are f**ked.

@@stevefitt9538 Steve, your first interpretation is correct. Supply will meet the demand that has the ability to pay; is the only truth in economics. If supply is short the price will rise. The geological mechanisms that produce geological commodities have been well understood for 70 years. Few new discoveries except small and expensive ones. Fossil fuels are entering the final production period where supply will decline and in a decade or so be too valuable to burn to produce heat. Critical metals, minerals and elements like copper nickle graphite cobalt phosphorous potassium and more are in increasing short supply so prices will rise. Another issue not realized by economists is the limits on the cost of energy. Energy is valued for the work it will do. Once the cost of energy approaches 10% of the value of the work it will do the activity becomes uneconomic. The world economy is in high overshoot. It is well past needing a planned and managed economic and population decline. Due to limitations of resources to move to low emissions energy, fossil fuels will be used to depletion, largely depleted well before 2100, accelerating global warming past mitigation. Your last sentence is spot on, just how soon I don't know but not many decades and depending which country. Interesting times ahead
