How Scientists KNOW Climate Change is Real | ClimateScience #2

How do we know climate change is real? You’ll have to look at ancient ice cores and supercomputer modelling to find out if humans really are the culprits of climate change.

ClimateScience is a registered charity in the UK led by over 150 young enthusiastic volunteers. Our mission is to empower people to contribute to climate solutions.

“We’ve known since the early 1900s that when we burn carbon-based materials, such as coal or oil, CO2 is released.”:

“We’ve also known since the 1850s that CO2 is able to trap heat.”:

“We’ve been collecting data about what we burn since the 70s”:

“we have actually been able to measure the parts per million of co2 for the last 800,000 years!”:

“We know this from studying ancient ice cores”:

“By analyzing these tiny trapped bubbles of air and knowing how deep they were we can learn about the concentration of CO2 in the air at a given time in the past!“:

“Because of these ice cores we can be pretty sure that the concentration of CO2 in our atmosphere today is higher than it has been in the past 800,000 years.”:

“ We also know that the rate at which the ppm of co2 is increasing is higher than past rates.”

“Today, scientists across the globe have set up measuring towers and ocean buoys to record global temperatures 24/7. And guess what? These temperatures have been steadily rising.”:

“We’ve seen glaciers retreating, reduced snow cover, a decline in arctic sea ice, and a resulting rise in sea levels.”:

“From these models, it's clear that the global changes we are seeing right now cannot be explained by natural phenomena.”:

part of the problem is you can't go back in time with thermometers or instruments to check your paleoclimatology assumptions. This is a problem in science because the scientific method suggests we can repeatedly retest our hypothesis until it can be disproved. Yet we need to be able to go back in time to strictly apply the scientific method to these assumptions. I would argue various components of climate science are a "soft science" not a hard science for this reason. This is different than say: re-testing the assumption objects fall to the ground at 9.8 meters per-second-squared which can be tested indefinitely and aren't dependent on the year or time of day.

So the end of the Ice Age was caused by what? Coal? Oil?

[muzlimah]

Best videos on climate change and global warming ever !!! Makes me wonder why you stopped making videos .

[LeGranDuck]

Keep up the good work guys
I love both the animation and the content
This is for sure just the beginning

[Jimi_Lee]

I don't see anything close to conclusive in this random collection of data. The climate has been on an upward trend since the ice age.

[ericdunbar]

So you're telling me this whole thing is based on computer models on super computers?!? Are these the same computers that can't even predict the weather correctly? What a scam.

People has always known what a change in climate means. The promotional term climate change started being used in the early 1980s expected to begin from global warming at 1.5°C causing stronger observable hurricanes in the Gulf-of-America (Gulf-of-Mexico). NASA reports global warming at 1°C where it has been since 1992 after falling from 1.1°C in 1991. The cause of global warming is not known. Earth's water vapor saturated greenhouse effect absorbs all the greenhouse radiant energy from the earth within a few meters of the radiating surface adding 5.55°C (10°F) to earth's average temperature and can't have its overall effect changed.

Warming is science. The climate "crisis" is political.

There are simple refutations to most of your points. CO2 was at 7, 000 ppm, and life thrived; this is known from rocks.
Humans live from the Amazon to Alaska. We'll be fine.
Oceans have been rising at 6 inches per century for thousands of years. Local changes beyond that are due to uplift or subsidence of the land. For the last 170 years, there have been daily harbor records, and archeological records before that. No acceleration has been detected.
The most abundant greenhouse by far is water vapor. The water left behind is cooled by evaporation. Warm air rises, but cools as it does so (density reduction). Eventually, the water condenses as rain, letting out the heat. The primary mode of getting heat off the surface of our planet is convection, not radiation. From the cloud tops, radiation kicks in.
"The warmest it's ever been!" The medieval warm period had grapes growing in England for 200 years! Then came the little iceage, and we're warming out of that. Of course temperatures are going up. And it's a good thing! Longer growing seasons mean more food.

The CO2 spike is Plant Food. Crop yealds are up, and earth is greener.
Only children are scared by your presentation. The adults know better.

Hilarious, at 30 seconds in they completely omit the greatest and most abundant greenhouse gas from their animation, water vapor. That comes from the evaporation of the ocean due to solar activity.

[ryanenglish]

Why then was CO2 6 times higher than now during the last four ice ages, when NY was under ice?

[vedangsista]

I really like this channel
I love the content too it is so good

Why do we still have central means of electricity production? When the solution is already available. Solar panels + Solar Battery (I have this already and in summer my electricity use is 100% solar powered) on every house, building, warehouse, school, rooftop etc. All new cars are Electric cars immediately, the ones with or without solar panel rooftops (already available). Just bring it in, never mind the inconvenience - all new cars must be electric by 2023. All new small trucks must be something like a rivian or tesla cybertruck or equivalent. All new heavy trucks must be hydrogen or electric trucks. That would be a huge help

yall often know far less than you think you do

Science we can believe, Scientist no.

S Global Warming Will End----God's Way

The Bible tells us that "The Former of the earth and the Maker of it.... did not create it simply for nothing." (Isaiah 45:18) The Bible also says: "The earth endures forever.".... Ecclesiastes 1:4, The New English Bible.

Yes, God will not allow the earth to be rendered uninhabitable. Rather, he will intervene in human affairs and bring an end to failed human rule and those who have no regard for the earth. At the time, he will preserve alive all who lead morally upright lives and sincerely want to please him. Says Proverbs 2:21, 22: "The upright are the ones that will reside in the earth, and the blameless are the ones that will be left over in it. As regards the wicked, they will be cut off from the very earth; and as for the treacherous, they will be torn away from it."

Up next. The tooth fairy is real… proof under your pillow. 🤡🤡🤡

childish presentation childish predictions

If anyone did their homework, and the producers of this video obviously didn't, they'd quickly discover that the info in this video is BS

[Echo_Lima]

noone knows where the emissions are coming from. they dont know if they are coming from natural emitters or coal . temperature used to be higher also during medieval ages . ppm increasement is tiny . oceans and volcanos emmit co2 also . nobody measured them to see if this is the cause . also in the poles they saw something else except what you are refering to. they saw star dust, star dust pays a huge role to solar activity and guess what ... the sun is the source of heat and thats why temperature is changing . there is not a single scientific proof that co2 emissions are in fact the cause of climate change .
