Doctors say 'fossil fuel addiction' kills, starves millions

[WiltonRanch]

So flipper show us the credible science from a credible source that says humans have little influence on climate change and that rising greenhouse gases don't matter. We are waiting.

Alvin Laws gonna come and kick some sense into an intolerant old creep like you.

Climate myth:
"Climate's changed before"

Climate is always changing. We have had ice ages and warmer periods when alligators were found in Spitzbergen. Ice ages have occurred in a hundred thousand year cycle for the last 700 thousand years, and there have been previous periods that appear to have been warmer than the present despite CO2 levels being lower than they are now. More recently, we have had the medieval warm period and the little ice age. (Richard Lindzen)"

Basic Answer:
Greenhouse gasses – mainly CO2, but also methane – were involved in most of the climate changes in Earth’s past. When they were reduced, the global climate became colder. When they were increased, the global climate became warmer. When CO2 levels jumped rapidly, the global warming that resulted was highly disruptive and sometimes caused mass extinctions. Humans today are emitting prodigious quantities of CO2, at a rate faster than even the most destructive climate changes in earth's past.
Abrupt vs slow change.

Life flourished in the Eocene, the Cretaceous and other times of high CO2 in the atmosphere because the greenhouse gasses were in balance with the carbon in the oceans and the weathering of rocks. Life, ocean chemistry, and atmospheric gasses had millions of years to adjust to those levels.

But there have been several times in Earth’s past when Earth's temperature jumped abruptly, in much the same way as they are doing today. Those times were caused by large and rapid greenhouse gas emissions, just like humans are causing today.

Those abrupt global warming events were almost always highly destructive for life, causing mass extinctions such as at the end of the Permian, Triassic, or even mid-Cambrian periods. The symptoms from those events (a big, rapid jump in global temperatures, rising sea levels, and ocean acidification) are all happening today with human-caused climate change.

So yes, the climate has changed before humans, and in most cases scientists know why. In all cases we see the same association between CO2 levels and global temperatures. And past examples of rapid carbon emissions (just like today) were generally highly destructive to life on Earth.

Mass extinctions. Are you serious. Took you 3 days to find that article.

The sheer diversity and amount of life on this planet in previous eons dwarfs what we have today. Maybe look up the Cambrian explosion. Its why we have oil deposits now.

Read my data post and weep in your coffee chuck. CO2 uncorrelated to temp clearly, CO2 higher numerous times before man was even on the scene. CO2 currently at one of the lowest points in earths history.

Are you denying those facts. Maybe you can get a job with the Stop Oil crowd.

Human Activity Is the Cause of Increased Greenhouse Gas Concentrations
So NASA, NOAA are wrong? And the climate scientists are making it all up? LOL Give up!

Jazz you can say what you want but only the flat earthers will believe you!

Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases.
How do we know what greenhouse gas and temperature levels were in the distant past?

The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels by nearly 50% since 1750. This increase is due to human activities, because scientists can see a distinctive isotopic fingerprint in the atmosphere.

In its Sixth Assessment Report, the Intergovernmental Panel on Climate Change, composed of scientific experts from countries all over the world, concluded that it is unequivocal that the increase of CO2, methane, and nitrous oxide in the atmosphere over the industrial era is the result of human activities and that human influence is the principal driver of many changes observed across the atmosphere, ocean, cryosphere and biosphere.

Chuck, do you understand anything about the mechanisms that cause CO2 to rise when the temperature rises? A hint, it wasn't because our single celled ancestors were burning additional fossil fuels to fight off the mild weather.

[chuckChuck]

Going to give us more climate denier bunk to prove NOAA and NASA wrong? LOL

Going to tell us again we are going to run out of carbon dioxide if we don't burn fossil fuels?

[jazz]

So its now down to posting feelings from the grifter IPCC group.

Doesnt change the facts I posted.

- no correlation CO2 with temp over planets history
- CO2 higher in the past before man
- now in one of the lowest points of atmospheric CO2 in earths history.

Do you deny these facts. Answer the question.

Conclusion, there is no man made climate change.

[chuckChuck]

So NOAA and NASA are wrong? Humans are not causing climate change at all? LOL Give Up!

[furrowtickler]

Well there is a correlation between C02 and temp proven by the graph posted
C02 follows temp rise , been that way for as long as those ice core records go back in history.
So your both right and wrong , depending on how one looks at things .
And yes the c02 levels were at one of the lowest points in history at the turn of the century.
That’s confirmed by both NOAA and NASA
Human impact on climate change is greatly exaggerated currently to push the new green energy fight against oil for control of the energy dollar needed to run modern society.
It’s all just a blame game of twisted facts to fight where your energy dollar will end up
It will eventually shake out somewhere in the middle with oil never going away and wind and solar never remotely being able to supply the energy required .
No carbon tax on international flights is just one example of how much of an exaggerated farce the whole carbon scheme is .

Chuck, quit trying to make anyone defend that ridiculous argument.
Everyone acknowledges that human activities affect the climate. What happens when you irrigate a desert and have vast areas of lush green fields of corn or alfalfa etc all respirating and absorbing sunlight
No one denies the effect on the climate of paving over millions of acres, which then become a heat sink absorbing all of the sun's energy and no longer have plants respirating.
The effect of damning rivers and creating reservoirs where they're never used to be has huge effects on the weather. As we have discussed recently, all of the particulate pollution man has been putting into the atmosphere is changing precipitation and cloud formation. Introducing species where they never used to exist or eradicating species which used to exist change the ecosystem which can eventually change the climate. Countless examples of human activities altering the climate, both good and bad.
Now if only we could find a way to change the climate to warm the globe to the optimum temperature for life on earth.

[fjlip]

Especially and maybe ONLY in Canada, because we are an ice box DEAD zone half the year.

[chuckChuck]

So A5 you have admitted humans are causing climate change but you never mentioned the biggest cause of human climate change which is greenhouse gases, especially CO2! That makes no sense at all but we know you ventured off into crazy ideas about running out of CO2 so this fits into your crazy thinking.

So how do you warm the globe to an optimum temperature for a vast and very diverse planet with many many climate zones without tipping the planet into uncontrollable warming? And which countries or regions get to choose the optimum for them that may result in less than optimum conditions for other regions or countries?

Which scientific organizations are saying this is possible or even a good idea?

For example, do you really think Kansas would want a drier and hotter longer summer so that central Alberta can enjoy a longer growing season and milder winters? LOL
