What I learned from "Star Talk with Neil deGrasse Tyson"

[robocop (actually)]

What I learned from "Star Talk with Nei deGrasse Tyson", from the world-famous astrophysicist and comedian, on climate change:

We've doubled the CO2 levels in less than 200 years- 100x faster than by nature.

1 degree celsius would power hundreds more hurricanes, floods, tornados, and blizzards every year.

The mayors of citeis around the world... have been getting together and forming networks and signing on pacts with each other to set targets and timetables for greenhouse gas emissions.

The temperature might go up 1 to 5 degrees in a hundred years, and there is still a lot of debate about how long it would take to reach the tipping point... I don't think we need to go drastic right away.

Pope Francis worked as a chemical technician.

Even if we depleted all our non-renewable resources we still don't know if it would turn out like Venus, but we would push earth easily beyond the point where we could live.

On a positive note I think it keeps the bugs from reaching full size.

Even if we depleted all our non-renewable resources we still don't know if it would turn out like Venus, but we would push earth easily beyond the point where we could live.

Do you mean that if all the coal and oil get used that the Earth will become too extreme for us?

Tipping towards extinction or towards rising sea levels or what?

Maybe Thanos had the right idea.

Have a lottery and take out half the population. No other solution seems plausible at this point. Otherwise I'm hoping science comes up with an alternative energy source.

Yeah, it is positive.

Do you mean that if all the coal and oil get used that the Earth will become too extreme for us?
Yes.

Tipping towards extinction or towards rising sea levels or what?
Inevitable extinction

Human extinction will almost certainly not arise from climate change, but large scale changes in climate will cause some areas to be far less livable. There will be pressure for entire populations to relocate and as you know from our southern border problems that sort of change is not welcome. Wars may ultimately result from this.

Higher temperature periods alternated lower ones many many times with humans around or not, I do not think that we can do much about this, of course, less industrial pollution would do us all good.

Hi leov, welcome to RF.

The book is paraphrased as, "We've doubled the CO2 levels in less than 200 years- 100x faster than by nature."

A few kilometers deep of ice covering melted very fast at the end of the last ice age melted rather fast.

I understand human activity contributed into GW but doesn't caused it, we do not really know .

The difference is that humans are causing this latest increase. It is not hard to understand. Why not avoid the avoidable? Are you saying that we cannot change the fuels that we consume?

I would not call thousands of years "rather fast":

The last glacial maximum peaked about 18,000 years ago and the ice was mostly gone by about 11,000 years ago.

E.g. How Much CO2 Does A Single Volcano Emit?
GW is mostly political scam, Imo. Attempt to redistribution of wealth. We do pollute and capable to pollute much less but we are not doing GW.

Ii do call it fast, very fast.

No, it is not. Yes, volcanoes can release a lot of CO2, but man releases more. Do you know how we can tell that man is the problem?

Then you are not being consistent. Man made global warming has barely begun. It will get faster and faster as the Earth wzrms.

You think it is fake article?

I do not think it is man made, Sun made, we contribute 1-2% (which is too much, if you ask me) but it does not push us into abyss, Solar activity may be or not.

it does not help you. We still know where the increase in CO2 came from. It was not from volcanoes.
