As deadly weather disasters sweep globe, is a 1.5°C warming target impossible?

Its doubtful that we'll make the 1.5 C mark. Many if not most of our climate models don't take into account what happens when previous carbon sinks turn into carbon producers. The data can be dated and at best its an extrapolation after the-fact. There's a high chance we'd end up in the situation of chasing a moving goalpost and never actually making it and many large funders have a vested interest in sowing disinformation stabilize corporate profits.

Given the disparity between renewables and fossil fuels currently in use, Nuclear Energy is the most likely candidate to offset energy use but corporations can't be trusted to run these kind of facilities.

Its already been noted that some carbon sinks appear to have become net carbon producers recently. Russian permafrost, and the Amazon. Basically it can happen when methane and other gases from the arctic/permafrost melt or natural disasters (large scale fires).

Carbon capture also isn't the only factor in a solution, trapped heat will need to escape the atmosphere to space and that can only happen at certain narrow wavelengths.

In most cases, very little attention is given to cascade failures in general, because in most cases its difficult to quantify the risk, and the worst disasters we see are often the result of these type of failures.

I would like to see more discussion about what we do in the scenario where we simply can't get it together - politically, individually, economically - to drastically slash emissions worldwide.

Is carbon capture a reasonable hope? What we can do to increase our odds that we figure that out before we start suffering real population collapse?

How much of an idea do we actually have of what a 3- or 4-degree warmer world will look like? How much do we think we can predict and how much falls under "this is a huge chaotic system and we can't know"?

I feel the slow progress to date will mean we will overshoot the 1.5 C by another 1.5 C and that will be a disaster. How does one country persuade a neighboring country to stop burning coal/oil? Cruise missiles?

Isn't it weird how we are willing to sacrifice earth for the sake of a number on a balance sheet?

That number supposedly represents wealth but how does letting climate change happen maintain wealth?

We’re already too late, we just don’t realise it yet.
