It’s not misinformation. We don’t have major eruptions every year. And only 5% of annual carbon emissions are anthropomorphic. I agree humans are responsible for increasing CO2, but not because of emissions. The earth should act as a buffered system, with utility of atmospheric carbon rising with carbon levels. There’s another paper in nature describing how the mass slaughter of baleen whales broke the iron cycle at…

It's misinformation because the natural carbon cycle adds and removes CO2 that keeps a balance. Around 750 Gt of carbon moves through the carbon cycle each year, and the keyword here is that it moves through. The natural emissions are always counterbalanced. The biological pump is one of the most important part of this system, which evolved to work like this. Unfortunately as it turns out this system can't cope with…

The krill - whale poop cycle was the fertilizer that fed the mass algae blooms in the Arctic that sink increasing emissions. That’s the point. It isnt burning fossil fuels that is the problem… it’s the fact that polar algae is way below normal levels because of a lack of nutrients due to the lack of baleen whales

The population of a country peaks a few years after it has gotten developed. As in low child mortality, high educated population, etc.

What countries do you think this is true of? Even, say, France is still growing. Let alone the US.

The population in most western countries are rising because of births + immigration. If just looking at births alone, then most of these countries would see declining populations.

Water infiltration is measured by digging a small hole, filling it with water, and seeing how fast it drains. There's no way that regenerative agriculture has changed soil composition multiple feet down, which is what would be needed for the soil to absorb multiple feet of water. I went to check the above sentence, and the first hit was this detailed article from Washington State, which analyses Brown's claims in det…

> . There's no way that regenerative agriculture has changed soil composition multiple feet down How do you know that? How deep do roots go? Do worms dig? Do you know? I do not. But I am not making assumptions

Read the article I cited.

I'm going to go out on a limb here and say that Pakistan's population in 2050 will be closer to 37 million than to 370 million.

Current pop is 220M, already closer to 370 ... I can see it not growing much, but not decreasing.

Climate change caused deaths. Famine, heat, draught, etc.

Maybe even relatively simple but massive reforestation efforts could help mitigate climate change effects in the long run.

Forests are not very good carbon sinks except in the short run. They have three problems when used as carbon sinks: 1) They tie up land for one, otherwise, non productive purpose (the wild species living in them do not mind that, must be said) 2) Once fully grown they reach a carbon balance. This can happen surprisingly quickly, a few decades. 2) Forests do not simply sit there like a rock. Eventually they will burn…

Agree but don't forests do much more for weather events than being carbon sinks?

AFAIK they also create a more moderate micro climate, reducing soil temperature, retaining humidity and rain while keeping it in the soil, reducing the risk of draughts.

Of course regenerative agriculture is much better but the effort to implement it at a scale is incomparably greater, while it should not be shunned.

Also agroforestry will help with making agriculture possible in larger areas of land.

With all due respect why are Glaciers melting in August.. or July or June. April and May are hot as hell in Indian Subcontinent. edit: glaciers melt in summer, I am surprised why they are melting in rainy season. No matter how you vote, just explain why this odd behavior.

Why is that odd? Ice melts when it's warm.

Because you would have signs of glacial melt ahead of time. You would know in may if not June. Not in end of august.

glaciers do have a certain minimum size, though.

It appears USGS roughly defines it as 0.1 square kilometers [1], or (being American) about 6 Walmarts. 1. https://www.usgs.gov/faqs/there-size-criterion-glacier

> 6 Walmarts?

Supercenter, Discount Store, Neighborhood Market?

So many sizes
