The Moon keeps the Planet in a 23.4 degree tilt, this is the reason for Warming and World Wide Forest Fires that burn Pine Needles and Grass Seeds

I could say "as if we have a choice," Then again, we do..
planet = crisis
plant = buffet
Carbon dioxide was 5 times as much as today, in the dinosaur era. Can't blame humans on that!
To clarify, WE aren't causing it just because of existing, we are causing by what we DO. With what takes to keep the world sns and society spinning and moving it takes a toll unfortunately.
Why is carbon 13 going down though?
ok. save earth. start with yorself and stop using internet, iphones, PC, all plastic and your synthetic clothes. go and live like amish
😂😂
HAARP
This is pure nonsense. Carbon dioxide has been as high as 8,000 parts per million, as opposed to the paltry 420 parts per million that now obtains. The earth is currently in the Holocene Interglacial Epoch because the earth is still in the Pleistocene Ice Age. Before the last glaciation, the earth was 16 degrees Centigrade warmer. Meanwhile, the earth's temperature hasn't risen since 1998. There is no climate change.
And the units of measurement are graphed as what, tiniest fraction of percent, or parts per gazillion, to look like a drastic, significant change? Graph for over thousands of years , with the same units, not isolating some small interval with panic inducing unit fractions. Figures don’t lie, but liars & schemers do figure.
Interesting that he leaves out the fact that temperature rises first then carbon in the atmosphere increases.
Climate Crisis fake news!
It's June 2024, Summer time in the UK…. AND IT'S FLIPPIN FREEZING !
Ah, finally a sweet graph to replace the old clown circus hockey stick graph. Every generation has a new and MORE scientific graph.
Theres no point in talking about it, because even with all the evidence people will deny it because they dont want to be exposed for actually not caring about there world there kids will be in.
😅😅😅
i forgot ..see Prof.Don Easterbrook 65years geologist, Phd climate science…the long (millions years)graphs show 0•1%coincidence and the 100 year graphs show the sea temperature goes up and then the Co2 graph goes up after it… Co2 comes out of the oceans effectively…ignore Everyone else its all bullshit.. no graphs..which is the only relevant thing…🎉
now i'll listen to your tape..but i cant be bothered to.. because the temperature Co2 graphs are the only relevant facts😊🧐🌡️
It's like being a chemist and observing an experiment for 3 seconds, then drawing a conclusion. This could be why so many actions that have been taken fail or are a detriment. Me, I'm not going to fallow the dooms day cult.
This is dumb! 12C has always been 99% of the carbon on earth. Your graph is wrong for atmospheric CO2.
How does carbon 13 rates affect the change in temperature
Actually I can't argue with that and moreover what the hell are you going to do about it.
Even if your little cabal goes totally green the rest of the planet is going to continue on with the technology that they have. Most countries are poor so, you might want to self delete before you see the extreme results in the next decades
Can somebody link the source for that?
Another climate change evangelist… 🙂
Filled the atmosphere with carbon lol it makes up 1/25 th of 1% of the atmosphere and that accounts for what's produced in nature as well
I remember one of the older videos on this channel explaining this and it's pissed me off ever since that this doesn't get mentioned very often. appreciate knowing it tho, impressed my science teacher that I knew about this stuff when we were given an assignment about providing anthropogenic climate change.
I thought it was already proven, and questioning it was science denial. Oh, but now it's seriously proven you guys we're gonna need so much more taxes now.
Oh God, it went from 320 ppm to 420 ppm! We're all gonan die! Quick, vote for more taxes. The government has our best interests in mind and can totally be trusted.
!Spread awarness!
Want to go back to the good days where you didn't worry about things like this?
Yes?
Ok!
Lets do our part!
What can we do?
-donate to charities
If your in the uk they have the red cross and green cross,wwf!
Google/search up charities in your country/state! People are copy and pasting things about animals and how to save them. Watching this video 3 times can make this video pop up on many fyp's
The past few years should taughtt us to be very skeptical of what we're told .
The main driver off climate change is not CO2 but rather the Sun. It is the Sun that increases and decreases in activity and this has a direct effect on climate.
What he dodnt tell us is that NASA photos show the earth is 20% greener over the last 30 years, and they attribute this to the rise in Co2. So plants are getting more plant food .
Has the earth had much greater levels of CO2 ? Yes.
Has the earth been warmer ? Yes.
Many people dont know tgat Co2 accounts for just 0.04% — a fraction of 1 percent — of the atmosphere , and that man accounts for just 3% of this . What is 3 % of 0.04% ?
The IPCC is cited as an authoritative source, but it is heavily politicized, and suffers from credibility issues , Climategate , for example. The Michael Mann bogus Hockeystick graph , recognized by the IPCC , is another.
There are thousands of scientists and academics who refute the IPCC's conclusions.
Then explain why co2 went way up after ww2, but temperatures went down. So much that another ice age was predicted. If fossil fuels are c12, didn't he just say that was plant food? Tree rings show co2 was almost 8000ppm. Now they are telling us over 400 is catastrophic? Not man made.
One hundred and eleven years since the hottest temperature ever recorded, remains unbeaten.
I do believe the schizophrenics brains are tuned into different frequencies
THIS DID NOT AGE WELL LMFAO
Hardly incontrovertible. CO2 still reflects incoming infrared from the Sun. Total solar irradiance has also been (very slightly) increasing since prior to the industrial revolution. It could be that the warming we see, if the stats of global temperatures are to be believed, is some warming due to the Sun's luminosity increasing.
Not saying your wrong but why is carbon 12 and carbon 13 only being discussed lately ? Unless i been under a rock and didnt catch this years ago
Well I know that this summer the sun is not out like it used to be. The weather is different now the summer is different also .our sun is it dying out on us.
So, we've added more C12 to the atmosphere which helps plant life thrive. Then, by extension helped all life thrive. Thanks to all who have helped with the greening of planet and giving us a warmer planet for all of us humans that actually enjoy life.
Can't argue with that!
Yes, humans are causing climate change, both recently and in the past. But on the long term graph it isn’t even a blip. And, the production of carbon actually has prevented or rather blunted warming, How? Great question glad you asked it. During the 2020 pandemic industry globally and travel ground to a haunt, resulting in the cleanest air world wide since the Industrial Revolution began. And allowed more Up and IR radiation to reach the earths surface. Bacteria in the soil then sped up their metabolic cycles and produced more Methane than is normal which is a far worse greenhouse gases than co2. Causing even more warming without human activity than with human activity. Secondly , producing greater quantities of co2 over baseline has increased plant metabolism and a greening effect, increased storm cycles watering typically arid regions and is partially reversing desertification which has been ongoing since about 2000BC. So, in fact , human production of Co2 actually is greening the planet. What is more, reducing Co2 will suffocate plant life and reduce O2 production. At present the earths atmosphere is at about 200 ppm of co2 at 100ppm the trees die. The typical commercial greenhouse is artificially kept at about 500ppm. Save the planet, produce more co2.
What will really help. Get rid of all the plastic. Switch to ceramic and glass at every opportunity, reserve plastic for medical use only and recycle it into more permanent forms and applications. And switch to clean nuclear and graphene energy production.
What (himan activities) creates the most carbon? Militaries…especially the 🇺🇸 army. In peacetime they're bad (for the 🇺🇸 that practically never) , but when they jump into their favorite business, war, then they create CO2 like there's no tomorrow. Then explain, oh "Smart One" , why you climateiers never attack the military industrial complex or the war business? You guys are corrupt! Nobody should trust you!
Scientists are great at discovery of anomalies among the common, and observations to build theories. But history has proven that they suck worse than weather forecasts at making conclusions based on it.
