Average World Incomes To Drop By Nearly a Fifth By 2050, Study Says (theguardian.com) 123

Average incomes will fall by almost a fifth within the next 26 years as a result of the climate crisis, according to a study that predicts the costs of damage will be six times higher than the price of limiting global heating to 2C. From a report: Rising temperatures, heavier rainfall and more frequent and intense extreme weather are projected to cause $38tn of destruction each year by mid-century, according to the research, which is the most comprehensive analysis of its type ever undertaken, and whose findings are published in the journal Nature. The hefty toll -- which is far higher than previous estimates -- is already locked into the world economy over the coming decades as a result of the enormous emissions that have been pumped into the atmosphere through the burning of gas, oil, coal and trees.

This will inflict crippling losses on almost every country, with a disproportionately severe impact on those least responsible for climate disruption, further worsening inequality. The paper says the permanent average loss of income worldwide will be 19% by 2049. In the United States and Europe the reduction will be about 11%, while in Africa and south Asia it will be 22%, with some individual countries much higher than this. "It's devastating," said Leonie Wenz, a scientist at the Potsdam Institute for Climate Impact Research and one of the authors of the study. "I am used to my work not having a nice societal outcome, but I was surprised by how big the damages were. The inequality dimension was really shocking."

          And that's problem #1. Thinking it's about force. People respond well to choice and when given choices, they will pick the better of the options. When forced, people will respond with resentment and opposition. "You have a choice, you can do A or you can do B" will get you a lot further than, "Do this. Do that."

              What choices for the end user? For the power industry, natural gas is now used far more than coal and it has a smaller carbon footprint, which helps everyone. The power industry also invests in wind and solar. But for the customer, the product has to offer a viable and better alternative than what you want to replace. You have to look beyond being an eco-oriented person who will just do it. Solar is still expensive (I have 15 solar panels myself), BEVs are still expensive, etc. Go up to Joe 6-pack or Mr Far

Choice number two was to believe scientists who said "we have a problem" and not protest at the city councils when things tried to change in small ways to reduce carbon output.

    The actual Nature paper indicates they estimate a 20% reduction in income relative to a baseline without climate impacts. Considering worldwide income has increased 120% in real dollars over the past 25 years, if the next 25 years is more of the same they are predicting a 75% increase in average worldwide income (inflation adjusted) by 2050.

    I don't feel that should downplay the wasteful economic effects of increased climate change over the next few decades, but the summary and article posted weren't very clear on what the prediction actually was.

Most people have seen a meager 1-3% raise per year and for about 5 years following the 2009/2010 housing collapse quite a few got 0% raises. Cost of goods has more than doubled in the last 2 yrs alone. Numbers mean fuckall if your actual spending power is in the toilet.
