Is there any hopeful news about climate change?


I would love to follow something online that can supplement what is a 100% bad news stream of climate change information. Can it really be that absolutely nothing is going well?

I studied econ in the 2000's and a theme that constantly came up was the Kyoto Protocol (basically a joint agreement between many countries to lower emissions). The US refused to sign for many years, which was seen by the rest of the world as tragic and unconscionable.

A few years later I noticed nobody was talking about this Kyoto Protocol anymore. It turned out innovation (in this case fracking) had caused gas to become more widely available, and since it causes lower emissions than coal, the US's emissions had fallen below the targets stipulated in the Kyoto Protocol even though it never signed, and this was achieved purely through innovation.

This gives me hope that problems we currently see as catastrophic could be similarly solved by innovation (e.g. by clean power generation becoming more economically viable than dirty methods).

Around a quarter of US electricity is now generated via renewables, and it’s growing fast. It seems clear to me that we will decarbonize the world’s energy within my lifetime. This still leaves us with a lot of carbon in the atmosphere that we’ll need to deal with.

It will, in aggregate, be much cheaper to avoid climate change than to pursue the status quo. For example, a recent paper showed a cost of $62 trillion to convert the entire global economy off fossil fuels, and a payoff timescale of only 6 years. https://news.ycombinator.com/item?id=33135183 There is still a lot of momentum, but as the effects get more noticeable and more expensive, there will be lots of cash and political will to get moving.

The impact of extreme weather events has been declining as a share of global GDP since 1990, people are good at adapting.

One of the high scenarios for emissions, RCP 8.5, which was used for modelling what might happen with climate change, is unlikely to happen:

Birth rates are falling in most if not all of the countries that consume the most energy, which will reduce energy use in the long term. Yes, it poses another set of economic challenges in places where population is shrinking, but that’s a problem we’d have to solve eventually.

Solar is competitive with coal for pricing, which means solar power is finally viable. Combined with energy storage devices, our reliance on fossile fuels has an end in sight!

We speak with more certainty than we really have. There is a lot we don't actually know.

Animals are adapting.

Animals are also evolving. New large species are emerging before our eyes, like a crossbreed of coyotes and wolves and a crossbreed between polar bears and brown bears (sorry, failed to readily find supporting articles).

Watch this list of short videos and hopefully it will change your mind: https://www.youtube.com/watch?v=hk9VQt5Nt64&list=PLxB143vg5_...

In my opinion short term things are getting worse indeed but in the medium future (10+y) it's going to start improving. What is really weird is that the "experts" completely lack the ability to recognize exponential growth (S curves) and model everything linearly. Especially episode 5 (~3:15) shows how coal usage has been massively over-estimated and not just a couple of years but 15 years and it's still going. And similarly how renewable energy sources are underestimated massively. The estimated time for going to 10TWh of renewables is ~2100, but it will most likely happen in 2030 (same episode ~10:00).

Of course, nobody says to stop worrying because things are actually bad. But just from the perspective of cost all energy will migrate to renewables and after doing that and price starting to decline to 0, we will be able to look into other ways to fix climate (e.g. recapture CO2 which currently is cost-prohibitive).

Brilliant Light Power claim to have a prototype device that produces 250 kW of light energy (mostly UV light) that can be converted to electrical power at high efficiency using concentrator photovoltaics with light recycling. See https://brilliantlightpower.com/plasma-video/

This all based on their Grand Unified Theory of Classical Physics that solves the electron orbit in hydrogen as a spherical shell of charge spinning in all directions (orbitsphere) instead of the probabilistic solution of quantum mechanics.

Note that the Wikipedia article about them is policed by skeptics and has not been updated much in at least a decade despite their major progress.

If they are right, $300B worth of their Suncell tm devices can essentially power the world pollution free and solve global warming.

The science establishment continues to dismiss their claims as rubbish and has done no significant investigation or testing.

Plastic-eating bacteria suddenly appeared (or were human generated, I don't know). This means, nature is adapting (if you view humans belonging to nature).

An example of nature adapting:

I read somewhere that when the first trees appeared about 380 million years ago. Their lignin could not be broken down. There were no organism who could digest that complex polymer. It took tens of millions of years. This was the carboniferous period. Wood accumulated without being broken down and got converted to coal. Then nature adapted and lignin get broken down. Coal is still formed but at a lower pace than in the Carboniferous period.

For me this means, the anthropocene is just one of the many periods of the Earth, and hopefully we will be fine. Let's cross fingers.

Most of the climate news we see on reddit/etc is just alarmism. Realistically according to the USGS we have 100-200+ years until warming becomes a serious problem, and I would be shocked if we don't have high quality solutions long before then. Further a lot of those "we're going to be underwater" figures are complete junk. Huge portions of the world have always (relatively speaking) been below sea level, and rising sea levels have nothing to do with it.

What is uniquely promising is that the world as a whole is getting richer, and once you escape poverty, people care more about their surrounding environment. If we focus on growth we're likely to see the environment improve naturally.

Canada will gain a lot of farmland in the upcoming years. So good news for Canada?

Yes! You'll be dead before the worst of it!

While backers of the RNC are the worst offenders in the US, please don't let the DNC off the hook:

Maybe the development of next generation nuclear reactors (small, midular) and their contribution to carbon zero 2050, as told here: https://www.nuclearnowfilm.com/

They said that 0.3 degrees of warming is currently hidden from the data by the way cities air haze clouds reflect sunlight to space. When the city haze is cleared up we'll get that 0.3. But this obviously implies that if things get really bad, we can simply invest a relatively small expense popping smoke at spaced intervals over a lot of ocean and cancel a degree or two's worth of warming that way while while decarbonizing. I was hyped for the apocalypse but it's yet another nothing burger.

if you’re in the US you should be fine. Especially Midwest and west should be good.

if you’re not you should probably get on it and come here

we have food, water, and energy.

More people die of cold related causes than heat related ones, by orders of magnitude.
