The key line for those who don't read the article: "Scientists say that global greening since the early 1980s may have reduced global warming by as much as 0.2° to 0.25° Celsius (0.36° to 0.45° Fahrenheit).

>increased amount of CO2 in the air as a result of anthropogenic activity Couple of questions because I'm curious... What percentage of the 0.04% CO2 in Earth's atmosphere do humans contribute? Has it yet been absolutely proven 100% that a gas comprising 0.04% of Earth's atmosphere is the main culprit/control knob which controls climate(s) around the Earth?

> Has it yet been absolutely proven 100% that a gas comprising 0.04% of Earth's atmosphere is the main culprit/control knob which controls climate(s) around the Earth?

Could you share some scientific facts that you believe to be 100% proven?

Would help to determine what your yard stick is here...

Uh oh, these questions smell like climate heresy Edit: for those struggling with the irony, my comment is pro-questions and pro-heresy. Let's not attack people for asking questions

Doesn't matter which side of the fence you fall on, it's good practice to validate the conclusions--and to continue doing so regularly. Please don't discourage people from asking for the data and the facts, no matter what your perspective is.

Just curious, could somebody explain to me quickly here how computers work, starting from transistors? It seems implausible to me that tiny electrical circuits could be used to produce logical operations.

I'm really just asking an honest question, and it's always healthy to revisit the evidence especially when you're making a big claim like "sand does maths".

You seem to have a lot of confidence that you are the only person to think of this.

First, this is already factored into mainstream climate research. Two, do you really think this is enough to totally offset the catastrophic effects of climate change?

Interesting to see an increasing number of climate change conspiracy theorists on Hacker News recently. Even more interesting to see COVID-19 conspiracy theorists too...

Does the IPCC conclusively prove with 100% certainty that the fraction of the 0.04% of CO2 comprising Earth's atmosphere humans contribute is the main thing which affects the Earth's climate(s)?

Yes. It's settled science. CO2 is not the only gas that matters, but it's the major one and most of the feedback loops are not in our favour. Read some of the technical reports, they're not that hard to understand.

Settled science is an oxymoron.

As far as I know this is calculated into climate change models.

So I'm curious based on what study you assume plants will flourish unlimited to compensate all additional CO2.

The IPCC report analysis increase risks with more CO2. Shouldn't the risk go down if plants would just compensate it?

And apparently the Amazonas as a whole org is now no longer consuming CO2 and is a net negative.

I think it was around 1 gigaton of CO2 caused by humans for every 40 gigatons of CO2 caused naturally, which is about 2.5% of total CO2 emissions every year.

Thanks, so that's 2.5% of 0.04%, right? Has it been proven that a gas comprising 0.04% of Earth's atmosphere is the main factor which affects Earth's climate(s)? I'm asking, because 0.04% of something seems like a particularly small fraction to have such a dramatic effect on a whole planet's weather and climate. Especially in a non-linear dynamic and chaotic - hence very difficult to predict - system like Earth's wea…

The fact that a small proportion of the atmosphere causes the greenhouse effect makes it more likely that the amount of CO2 we are adding is affecting the planet. It's easier to make a significant change in a smaller quantity.

If you have doubts about the scientific understanding of the greenhouse effect, study up on that. But continually bringing up that 0.04% makes it sound like you are clinging to that fact as a "gotcha" and avoiding learning anything more.

Don't forget government-led research is how Covid started in the first place - our tax money was used to fund the creation of the virus.

Can you elaborate on this? That sounds insane.

The consensus of climate scientists is wrong, everyone! The consensus of economists is wrong, everyone! We all just overlooked this one simple fact.

A few more plants will grow... and then we'll still see the ecological collapse that is the true fear. And those plants are going to de-acidify the ocean anytime soon.
