The whole Western world has shifted rightwards in recent years as can be witnessed in election results.

it's because the left has been attempting to make progress too fast, without regard to the people who lean towards the right as tho their point of view is universally regarded as being wrong. Reactionary politics is real, and the left ought to be more aware. Leaning towards left (aka progressive) is good, but if you're not paying a cost for it, someobody else is - and it's likely someone leaning right that's being fo…

The bicycle machine emits nothing and can be used pretty easily in cities.

> The bicycle machine emits nothing The tires and some types of brakes still emit micro plastics.

How much? If that's 1% of car (making this up), would this be a real practical issue?

By the way this argumentation is great to sabotage any argument to keep the statusquo. When someone argues for a way better solution, tell why it's still not 100% perfect to make people to believe it has the same flaws than the previous state. Repeat until someone finds a 100% perfect solution (hint: there is never such a thing).

Emits nothing only if you ignore the engine. Some studies suggest that human CO2 emissions increase eightfold while exercising.

Which made me learn today that electric bikes might produce less emissions overall than traditional bikes https://www.bikeradar.com/features/long-reads/cycling-enviro...

TL;DR Climate models are showing that a parameter (ECS aka “climate sensitivity”) has been increasing since 2019. This parameter determines how much temperature increase can be expected if atmospheric CO2 doubles.

I find it very confusing that this is supposed to be new knowledge. Shouldn't the correlation bewtween CO2 concentration and greenhouse effect been researched and simulated to death by now?

@dang Is it just my impression that HN is drifting rigtwards on this topic? I remember HN being more in favour of proactive action against anthropic climate change. This thread feels dominated by attitudes reflecting inaction.

Is that wrong? Is only one narrative allowed in a discussion (it's not a discussion then is it?).

Millions or billions of years after you're dead makes as much difference as 25, that is my point.

As for the rest of your calling for banning, people can look at my history of more than 10 years of comments on HN and decide if it's fair to call for banning someone like this, lol.

Until the war is over, we can't know if exploding things non stop for two years is having a part in making the last years warmer. The models could be incomplete, or obsolete

The amount of energy accumulating in the oceans is equivalent to detonating five Hiroshima atomic bombs per second, every second over the past 25 years. https://link.springer.com/article/10.1007/s00376-020-9283-7

This does not change what I said.

We had past long time ago the question if is happening or not. What I'm discussing is the "how fast" part.

The sub-question is if the war or wars if you prefer (You all know what I'm talking about) are causing the current wave of claims "I'm worried now but I was not worried yesterday"

I assume that the war is making it faster, but the effect of this particular factor could be temporal. Artifacts happen in science all the time. We don't know if war is a modifier (and in that case if would be a temporary or permanent modifier). I personally suspect that it has an impact. I could be wrong.

1) there are still trillions of "subsidies" (that includes some negative externalities)to fossil fuel each year according to IMF (IMF, not Greenpeace!).

2) Agents in the current system have incentives to prioritize short term benefits over longer term benefits. And a lot of climate related things are short term cost/investment for "profitable" long term benefits ; the current system sucks big time in this configuration.

3) The people having the least negative impact from climate change are the countries emitting the most greenhouse gas. The countries the more negatively impacted by climate change are countries contributing the least to climate change. There is a big misalignment of interest there making a purely "free market" "economical" solution difficult.

4) There are a lot of case in the real world were there is a strong economical incentive to switch to something different and were the different agents just don't... Because people don't want to change, because there can be some particular interest in the system, because of political motive... Human is not a rational animal, and his rationality is not only dictated by money

5) We need to do more than just switching from fossil to "green electricity"
