Geology ice cores fossils.For the 800,000 years we have records of, average global CO2 levels fluctuated between about 170 ppm and 280 ppm. Once humans started to burn fossil fuels in the industrial era, things changed rapidly.Your problem is that you think you know more than the scientists.
1) We know temperatures are rising ad rising faster than what we know about natural warming.
2) We know the heightened carbon content is the major factor.
3) We know heightened CO2 increases the greenhouse effect & that raises temperature.
4) The increase in CO2 in our atmosphere stems from emissions.
5) Therefore, anyone with a fucking brain knows the solution is to reduce emissions.
6) It takes the Earth decades to natural remove excess CO2 from the atmosphere. This is why we need to act now to prevent higher temp increases in 50-70 years.
7) Our current climate includes things like volcanic eruptions, fires, etc.
We can heat our homes without creating emissions
We can drive electric/hybrid vehicles
What does communications have to do with anything?
The solution is is reduce emissions to the point where the carbon levels are reduced & maintained at lower levels.
The longer we wait, the worse the temperature rise will be.
Instead of working towards this, a bunch of really ignorant people elect a President & Congress that is bought by the fossil fuel industry to fight efforts because the burning of fossil fuels is the biggest contributor to high CO2 levels. These people have duped the right into condemning their own offspring to a more difficult life. How stupid is that?
I cut my carbon footprint in half. My just as warm in winter, cooler than yours in the summer, and I drive just as far as I always did.
You are lying & ignorant when you claim you actually might have to sacrifice something for your Children.
No matter what figures you find, there is no way to prove man is responsible. Every single human being emits CO2. There is just no way around it. We have over 7 billion people on this planet and growing. 7 billion little C02 producers. What do we do about those? What happens when it goes to 8 or 9 billion?
What changed in the past 100 years that would increase the CO2? Industrial revolution?
Yes more people but it isn't our CO2 it is the CO2 generated by our transportation, HVAC, factories, etc.
I'll wait for your
What.....you think there are different C02's or something?
Whether you want to measure temperatures or climate the last 100 years or the last 1,000 years, it's like measuring two minutes of the day to determine what the weather will be like for the rest of the week.
Our normal temperature here in Cleveland today is 36 degrees. We hit 28 yesterday, 32 today, and tomorrow it's only going up to 26. Is that indicative that our planet is cooling? No. 36 is an average and any deviation of that is perfectly normal. It could be 15 today and 45 by Friday, and that's still normal.
So if the earth is heating for a couple hundred years, it's not abnormal. In 500 years from now, it could be cooling. Nobody knows what the average temperature of our 4.5 billion year old planet is because it's has always been changing during that time.
Only in the industrial era has the number risen above 300 ppm. The concentration first crept above 400 ppm in 2013, and continues to climb.
Scientists debate the last time CO2 levels were this high. It might have happened during the Pliocene era, between 2 and 4.6 million years ago, when sea levels were at least 60 to 80 feet higher than today. It may have been in the Miocene, 10 to 14 million years ago, when seas were more than 100 feet higher than now.
In our 800,000-year record, it took about 1,000 years for CO2 levels to increase by 35 ppm. We're currently averaging an increase of more than 2 ppm per year, meaning that we could hit an average of 500 ppm within the next 45 years, if not sooner.
800,000 years ago we have records? We couldn't even communicate with each other yet. First you say it's mans fault, and then in the same breath, say that this has happened several times before long before the first car or factory. In other words, it wasn't because of us.
Our C02 levels have been decreasing the last couple of decades in this country, and things are worse now than ever? Don't you see a problem with that?
