How does this effect earth

How does this effect earth?
What does it effect?
Rotation, climate, gravity, etc or nothing?

Keep in mind Hydrogen is an indirect greenhouse gas with a global warming potential GWP of 5.8 over a 100-year time horizon.
Global environmental impacts of the hydrogen economy | Advanced Global Atmospheric Gases Experiment.

Scientists estimate that the Earth gains about 40,000 tonnes of material each year from the accretion of meteoric dust and debris from space. They also estimate that about 95,000 tonnes of hydrogen gas are lost from the Earth's atmosphere to outer space each year.

Did you read the whole article? It tells you why it would be mostly meaningless. But let's run some numbers.

The mass of the oceans is 1.37 * 10^21 kg. About a tenth of that is hydrogen. Let's round down to 10^20 kg. The story says 95,000 tonnes of hydrogen lost every year. Let's round up and put that in kgs. That is 10^8 kg of hydrogen lost per year. Divide the amount be the amount lost per year and we get 10^12 years to empty the oceans.. The Earth has been here only 4.5 * 10^9 years. Or long enough to lose 0.5% of the Earth's water in all of that time.

I'm not clear what you are asking about. Is it whether the current rate of net loss of hydrogen affects climate, or is it about the potential impact of a future hydrogen economy, as discussed in the link?

100,000 tonnes is a very, very, very small amount compared to the total that exists on the Earth.

How much would it affect you if you lost one skin cell per year?

It seems to me the issue is not so much the rate of loss of the element from the Earth as a whole, but the rate of change of the concentration in the atmosphere. I think I'd expect that to stay almost constant until the oceans were severely depleted.

But, if we were to have a hydrogen economy, with the inevitable accompanying leaks, it could be worth running the numbers to see if that might be enough to have a significant effect.

Don't worry. None of this is going to affect the earth for 100 million year, and probably we will not be around till that time.

Well I would say it all is equally required.

I mean how will your car run if it's completely missing a measly battery cable?
