Where I disagree is on the principle that the end is nigh. There are things we can do, but the idea that we can stop global warming entirely is ludicrous. The earth is going to warm up no matter what we do. Even if we stop burning all fossil fuels it will STILL warm. And rapidly too, because now that the glaciers are almost gone and the arctic ice pack is receding the cycle out or the ice age is irreversible.
Another big problem is the melting permafrost. As it melts it releases methane, a greenhouse gas. Once a lot of these processes start, they're self-reinforcing on a level that we can't stop. It's retarded to think that any of this stuff will be the end of humanity. Like glacial-fed rivers. That's what ended the Indus Valley civilization way back at the dawn of history - the glacial-fed river dried up. Was the Indus Valley devoid of human life after that? No, civilization just reorganized itself to better adapt to the available level of water, and neighboring powers expanded their spheres of influence into that vacuum. If the Columbia River dried up after the glaciers all melted down, Eastern Washington would just start looking more like Eastern Oregon - no endless spread of vineyards and orchards. But other areas would become more wet, more fertile, or have longer growing seasons.
The flooding stuff is also retarded. You know what area has been flooding for thousands of years? East Asia. Did they all just throw up their hands, starve, and float down the river? No, they built infrastructure to harness the seasonal rains and grow a lot of food crops that require flooded paddy cultivation, like rice, water chestnut, or lotuses. I know with lotuses they even do joint agriculture-aquaculture in the pools, growing stuff like crawdads or fish. The ancient cities of the Khmer had crazy levels of infrastructure set up to capture and manage those seasonal floodwaters, and Angkor was once the largest city on earth. England is now growing sparkling wine at scale for the first time in ages, with Champagne houses making heavy investments there. And Champagne, historically, used to produce still wines - maybe they will again in the future. All of this shit will happen slowly enough that most people will be able to adapt and modify what they grow and how they grow it.
That is, unless the retarded green lunatics get their way and do things like banning meat and dairy production, which is my pet peeve. There's a reason that so much cheese is made in the Alps - lands at a certain steep grade, if they aren't terraced, are not suitable for traditional agriculture. And because we aren't under a feudal system anymore, under which most of the stone terraces that we use today were built, it doesn't make economic sense to make that big of an investment into farming land. If you try to turn the alpine grazing meadows over to traditional crops the soil will all wash away, or it is too thin, poor, and rocky to support traditional crops in the first place. There are whole classifications of soil, separated by both physical qualities and grade, which are only suited to grazing. If you take away that land use, you will either destroy that land's ability to support life or remove the economic incentive to preserve that nice wild grassland up in the mountains, which will be developed into ski chalets for rich assholes.
Same goes for trying to eliminate paper - the paper industry
farms trees for paper. Rotational forestry gives an economic reason to keep that land forested, without that financial incentive the land would be cleared for farming or to build shitty townhouses for a bunch of pajeets (who will move into them from India and consume 100x the carbon they would have in their old country). And if the forests are coppiced, it's absurdly environmentally friendly - and coppicing is used for paper pulp production. Because the trees are cut back to the roots and then allowed to grow multiple trunks from the old root system every decade or so, the root system grows larger over time, sequestering carbon underground. But I constantly see these carbon-obsessed retards trying to replace all paper with shitty tablets or other electronics, which all rely on environmentally devastating rare earth mining and processing, and use electricity. This reduces the demand for paper drastically, therefore reducing the demand for land to be used in this very environmentally friendly way. And paper is much more easily recycled too. Just sheer idiocy, I have no patience for these morons.
