What is Climate Change? | Start Here


Let’s talk about climate change. People are calling it the crisis of our time, and it is. “climate change “climate change” “climate changes” “climate change” But it’s easy to get lost in this story. The science is dense, and politics get in the way. World leaders are meeting in Madrid to talk about the climate crisis and how to slow it down. And they’re under pressure from millions of people around the world calling for concrete action. The empty promises are the same and the inaction is the same. So what exactly are we doing wrong and how do we fix it? We’re going to kick this off with some basic science. So bear with me, because this is important. Look at this graph. These are the levels of carbon dioxide in our atmosphere over hundreds of thousands of years. But this spike in carbon dioxide at the very end? That took off during the industrial revolution. We started breaking CO2 records in 1950, and we haven’t stopped since. why? Well, scientists say there’s a 95% chance that human activity is the cause. We’ve been burning more and more fossil fuels like oil and coal, which release CO2, to power our homes, factories, airplanes and cars. There’s also a lot more of us. The global population has tripled in the past 70 years. And we’re consuming more products from animals that release another pollutant called Methane. So all those gases are in the air, and when sunlight gets into the earth’s atmosphere, some of the heat gets trapped, and the planet gets warmer. That’s why they call it the “Greenhouse Effect”. But the concern is not that the earth is getting warmer. But the concern is not that the earth is getting warmer. “It’s actually the warmest temperature on Earth since the last ice age since 10 thousand years ago.” The UN says that right now, our world is about 1 degree hotter than pre-industrial times. That’s around the year 1800. Which is okay. In fact, the UN says if we warm by 1.5 degrees before the end of the century we should be fine. The UN says even 2 degrees would ‘probably’ be alright. But again, the problem is speed. Because right now, we are on track to hit 1.5 degrees in only ten years. And If we don’t slow that warming down, it could mean catastrophe within my lifetime, and maybe yours too. And we’re already getting a taste. “Climate change is here. Climate change is happening. We are well into the 6th mass extinction event.” ”Europe is currently colder than the Artic.” “More than a thousand people being rescued just in the early morning hours of Sunday.” “Millions of people are likely to suffer worsening food and water shortages.” ‘The drought that’s now in its tenth year is a phenomena that’s here to stay.’ “We’ve never seen a year’s worth of rain in less than seven days.” Sea levels are rising about 3 millimetres a year because seawater expands as temperatures get warmer. Melting ice sheets and glaciers also add trillions of tons of freshwater into our oceans. People around the world are already losing their homes. And if things carry on, millions more of us will have to pack up too. Entire coastal cities could be underwater within 80 years. Like Miami in the US or Osaka in Japan. Entire island nations in the pacific could completely disappear. “Natural disasters becoming more and more intense, more frequent with devastating consequences. The dramatic impacts of droughts in different parts of the world, all of this is creating a situation that is a real threat to humankind. And we are not doing enough.” “If 99% of doctors said to you, ‘take this medicine, or you will get really sick and probably die’ you would take it , who wouldn’t take it? the problem is, at the moment, we don’t have any medicine.” Now, there is a plan to slow all this down. Back in 2016, world leaders signed the so-called ‘Paris Agreement’. And the big pledge is to cap temperatures rising by 1.5 degrees or a maximum of 2, before the year 2100. So countries set their own targets on how much CO2 they emit. But here’s the thing Three years after the agreement, global CO2 levels are still going up. “CO2 emissions have been going up the last year by two per cent so that’s actually above the average of the last ten years. So it’s started to increase again and it doesn’t look too good. In some ways, we’re going backwards. “The United States will cease all implementation of the nonbinding Paris accord and the draconian financial and economic burdens the agreement imposes on our country.” The US, one of the world’s biggest polluters, has pulled out of the Paris deal. Russia and China are accused of not giving themselves ambitious targets in the first place. ambitious targets in the first place. Turkey and Poland want to build more power plants that use coal. And then there’s the sceptics. It’s a political decision, that it’s man-made global warming. We forced the computer models to say AHA! Human influence, CO2 and other stuff. “The ground base temperature data has been massaged to show an increase but the satellite data shows no increase.” On the other hand, there is positive momentum. There’s more awareness and some countries are making progress. India, Morocco, and The Gambia have massive renewable energy projects. There are different countries doing different things really successfully some countries are, for example, making all public transport free in the cities. What a great way to encourage people out of their cars. But experts say what’s needed now is an even bigger push to change everything about the way we run our world. Business as usual has got to change. Politics as usual has got to change In order to combat that we have to change the system that has allowed it to happen. You can’t have infinite growth on a finite planet. And everyone can do that by shifting to renewable energy, reducing the use of cars, use trains more, cycle more, eat less meat consume a bit more carefully. So where does that leave us? Well there’s only so much bike-riding and light-bulb replacing you and I can do everyday. But the truth is that it’s those everyday things that are going to change anyway. Even coffee could run out if farmers can’t grow it. So the expert advice? Is that it’s down to all of us, to change our ways and shake things up, or climate change is going to do it for us.

  1. The elites knew this would happen, they were warned. They just not being upfront with us an telling us the truth.

  2. Even the biggest skeptics have to admit that human activity is a contributing factor, and the truth is that's the only factor under our direct control.

  3. ๐ŸŒฟ๐ŸŒฟ๐ŸŒฟ๐Ÿ—ฝ๐ŸŒฟ ะœะžะ–ะ•ะข ะ’ะกะ ะญะขะž ะšะะ ะ ะ‘ะžะ“ะ!?! ๐ŸŒฟ๐ŸŒฟ๐ŸŒฟ๐Ÿ—ฝ๐ŸŒฟโ˜๐ŸŒท

  4. How much CO2 is the result of unnecessary manufacturing due to planned obsolescence? What do economists say about computing consumer depreciation of the junk every year? Shouldn't so called scientists have noticed?

  5. So here's where your are stupid, combustion does not create CO2, just CO (carbon monoxide) which is poisonous to humans. CO2 (dioxide) is what humans and mammals exhale. It's also what plants inhale. What do you think is there bubbles in your soda pop? Infused carbon dioxide to help fill the can with less liquid and it's what you burp. It also has health benefits for us. So the media needs to stop spreading this anti-knowledge. There's also no such thing as fossil fuel. Oil does not come from decomposed dinosaurs, it's all organic material that has decomposed. You would know this if you ever composted your yard clippings. It is a renewable source. Global warming is a scare tactic, don't become victim. Please.

  6. You have headache's = climate change
    You have a diarrhea = climate change
    You can't pay your monthly Bill's = climate change
    Don't want to have sex= climate change
    Wars around the world= climate change
    Peace around the world = climate change
    Nobody buy's your global warming= climate change

    It is so funny that you can use "Climate Change" for everything under the sun.

  7. You say to subscribe your channel to never miss an episode, but even after subscribing I dont get all the videos from al jazeera in my subscription feed.

  8. PROPAGANDA pure and simple…Many ppl do not realize that the Sahara desert was once a lush tropical rainforest, barely 6000 years ago but now a harsh baren wasteland…too many cows farting? Or just the natural life cycle of this realm we call home?

  9. At 2.43 we are in 6th mass extinction, cognitive dissonance is so obvious. Our world is a done did deal, I AM fully aware of this, the frustrating thing is so few seem to grasp. Just look at the comments they are๐Ÿ™Š๐Ÿ™‰๐Ÿ™ˆ.

  10. "climate change" is Satan's deception tool. The Bible states all this will happen more and more frequently as a woman bares a child before birth. At this time nearly every country on the planet is protesting their government or athority figures. The world is crying out for a savior without even knowing it. But those of us who are awake know that Jesus is returning for his bride before the worst. Repent of your sins and give your life to Christ before its too late! Eternity is at stake!! I love you all, God bless you brothers and sisters!

  11. Loved d way she explain everything in an interesting and easy way…climate change nvr gonna stop unless we change our own habits n lifestyle but it is inevitable there will always be climate change d only thing we can do is to slow down d impact that it will make on us

  12. Did she just show the, now famous, fake J curve!
    Throw in the United nations reference, throw in lots of "could be" statements, throw in old flood videos.
    Perfect brainwashed article.

  13. Bull itโ€™s the mark of the beast Sunday rest by law by the pope and that little girl ๐Ÿ‘ง Greta we are in the last days

  14. It's easy for us to be lied to! We don't need to see your video we have eyes! We know the true intentions of this video is a scare tactic but if you really care about climate change then drain the swamp of corruption! That should slow down climate change dramatically!!! That's why Trump pulled out of the deal and we back him!! Don't be fooled people! Just do your own part to do what you can!

  15. Pollution we can stop because we produce it. Climate change we have little to do with because our Sun and the environment affecting it produces it. We've been deceived by those who know little of the true cause of Climate Change – mark my words; you will know more in 2022.

  16. You have to admire the resolve of some politicians. Bushfires are literally burning out of control over hundreds of thousands of acres across Australia right now (no exaggeration!) but our government is adamant it's got nothing to do with climate change. Like most people, I don't believe them!

  17. And what about the millions of people that dont agree . The science is not IN, it is not definative. Climate change is real it has always been changing human influence is negligible and CO2 cause is suspect. What can we do, plant trees and adapt, beyond that you are just being alarmists.

  18. Fist of all…CO2 levels have been higher…you just failed to go back in time enough..it makes your lie look real. Of course it was before man walked the earth…and that makes it hard to blame humans does it not?

  19. The world has been in a cooling faze for hundreds of thousands of years…again, you only went back 10 thousand years…to a short warming faze that ended around 2009. Lady, do you not realize how old this planet is?

  20. Itโ€™s not CO2 itโ€™s the sun. We are going into a Grand Solar Minima, the son is going into a long cooling faze. What is my evidence? Check what the temperature is doing on every planet in the solar system. Please, get your facts checked, flooding, and droughts are effects of solar cooling.

  21. Sea level is not rising! Why? Because the sea floor is sinking at a rate of over 3 inches a year. New studies are showing no increase in overall sea level and have noted that most studies did not equate for the sinking sea floor. What is interesting is that the sea floor is sinking much faster than any sea level rise.

  22. Without CO2, we are dead. Plants need it to grow. Your putting all your eggs in one basket…with CO2…why. MONEY..A CARBON TAX DESIGNED TO MAKE THE RICH RICHER. This is the planet Earth…the climate has been changing since day one…long before man walked on it…and guess what…the climate will be changing long after we are gone! Prove me wrong.

  23. Lady..you show those massive solar arrays like they are great for the environment! Do you not realize that the air temperature over those massive solar arrays is over 900 Degrees Fahrenheit? The air is so hot that birds flying over burst into flames and fall burning out of the sky. Talk about solar warming! Hundred of thousands of birds fry flying over these things ever day. Huge flocks of migratory birds set on fire in the sky trying to fly there migration routs. Looks to me like you need to wake up…

  24. The only thing you got right, is that Climate Change is going to change us. It hurts to see Al Jazeera becoming US Main Stream Media…I thought you were better than that. But as far as this story…you really blew it. So..my offer…you donโ€™t like my comments, challenge me. Prove me wrong..better yet..letโ€™s sit down and compare facts. Either way…soon enough the garbage your putting out is really going to stink.

  25. Notice it's only people that sit in offices and have soft hands that advocate shutting down all industries? Probably because they've never done a real days work in their lives and can't even fathom what it takes to keep an economy moving.

  26. The little ice-age was from 1300 -1850 we are coming out of that so naturally, there is an increase in temperature. From satellite records from 1979 temperature has increased by 0.13C per decade which is aligned with a natural increase, this has nothing to do with CO2. To combat natural climate change we need to build sea walls etc. This requires engineering and technology not riding your bike to work.

  27. To get rid of using fossil fuels for the valid reason of air pollution you first need to have a workable system. Unfortunately, wind and solar produce unreliable energy that is problematic for the way we use power. Search Jo Nova How to destroy a perfectly good grid or Michael Schellenberg.

  28. Greenhouse gases like Carbon dioxide, Methane, and Water vapour can't heat the planet or trap heat for any length of time. A tropical jungle at the equator might feel hotter but the temperature has been buffered compared to the heat in a desert. We do not live in a contained system it is an open system which allows heat to escape. Heat rises by convection and it is only slowed temporally as it passes through denser materials like water vapour. Carbon dioxide and methane are trace gases measured in part per million / parts per billion respectively in the atmosphere, they simply can not radiate heat energy back to heat the planet. The human body emits infrared energy/ heat so imagine trying to heat the floor in your lounge while suspended 2 metres off the ground and there is no roof. Any small heat escapes and head upwards. The main heat source is the Sun and atmospheric pressure helps to maintain heat levels. it is the reason why it is colder at the top of the mountain and warmer at the surface and why the core is a molten ball.

  29. Ohhhhh…. I get it now. The problem is man-made. The people are at the epicenter of climate change.
    The solution is simple. A war that eradicates ~7 billion people would fix CC?? I'm all for that!

  30. It is sad but is is too late we should trade in cars fforr hybrids it would at least slow it down. Also destroy the fossil fuel factories. We should make clean air factories. It is mostly the fossil fuel factories

  31. Sea levels have been rising between 1.8mm to 4mm a year since the last ice age. CO2 was higher than the current value millions of years ago.

  32. This could have been done a lot better. They wrongly focus on urging individual consumers to make lifestyle changes. While that does matter to a degree, the real problem is that the corporate and political elite are deliberately choosing to downplay the importance of climate change in the media, and many have worked very hard on campaigns to spread doubt about the science and make it seem like a hoax so that they aren't held responsible for their oversized role in pollution.
    As long as the single most-watched TV news network in the USA (Fox) continues to outright deny climate change, tiny outlets like this one aren't gonna make a big difference. Fox is the chief information source for tens of millions. Whatever they say is what half of the USA will believe.
    Also, putting the onus on consumers rather than governments and corporations is an intentional strategy to deflect attention away from the real culprits. They want you to worry about taking quicker showers (or something trivial like that) while they continue putting off upgrading their behemoth-polluter coal plants and other sources of actually significant greenhouse gases.

  33. There have always been natural disasters. Only idiots think it is climate change that is responsible for every flood and fire on earth.

  34. This spike in carbon dioxide took off during the industrial revolution. We started breaking records in 1950. ACCORDING TO THIS WOMAN.
    But the industrial revolution started in 1760.
    Maybe she should start with the truth.

  35. She states:- "Even coffee could run out if farmers can't grow it"
    From the website of "US National Library of Medicine
    National Institutes of Health Journal of experimental botany"
    Published online 2015 Oct 26
    :-
    "Given these facts, we therefore suggest that coffee will greatly benefit from the rise in atmospheric [CO2], as will other species where photosynthesis is largely limited by CO2ย diffusion.
    "

  36. 1:12 "We have been burning more and more fossil fuels" (while severely reducing the number of trees/forests, and so diminishing the capacity to catch all the excess CO2).

  37. The Co2 chart is very misleading. Why just go back 400 years?? Because 10k years ago the Co2 level was 3x higher than now. Why not go back 100k years when the Co2 level was 7x higher than today. Oh I know why, it dosen't support there agenda. This is called "CHERRY PICKING" the data!!!

  38. Yes there is a 95% chance that humans are the reason for the Co2 spike starting in 1950. However, it is not proven that this is a causing an issue for the environment. Real scientists are still debating that topic. The earth did very well in the past at 9x the current Co2 levels. Dont fall for the propaganda, this video still promotes the false alarmists agenda!!!!

  39. Research HAARP. You'll discover they use this technology to manipulate weather and climate change is a deliberate fabrication.

  40. Within 50 years we may see Maldives under water. Every country is already suffering but none will do anything. But they must understand disaster will not see wealth, religion or economy. It will destroy anything to restore nature.

  41. Climate Change is a naturally occurring phenomenon.
    CO2 makes up 1/25th part of ONE percent of the earth's atmosphere.
    The dominant 'greenhouse gas'; water vapour is in limitless supply.
    Al Jazeera is fake news.
    There, I think that's covered the most important points.

  42. Temperature rise is 0.7C, sea level rise is 1.5mm and the Paris Climate Accord is a wealth redistribution mechanism that has nothing to do with climate change and everything to do with replacing capitalism with socialism. So, please pedal your alarmists bullsh*t elsewhere.

  43. What is climate change? It's NOT Global Warming. Record cold and snow last month and this month and for the last 3 years. Remember Al "your children will never see snow" Gore, he lied. Climate Change is a cycle controlled by the sun only, not man. CO2 is not a pollutant. If you have been brainwashed into believing CO2 is a pollutant then STOP BREATHING! YOU exhale 42,000ppm with every breath. Multiply that by 7 billion people, 500 billion animals times how many breaths are taken. Without CO2 life would not exist on earth.

  44. this propaganda is like; alien, ufo to scare humanity…it's not true. Question to these people who are spreading this scare; Is the earth average temperature is increasing from 15 degree celsius? give me the number please and the atmosphere green house gasses emission please!

  45. so we have 0,4% CO2 now. And this gas alone has almost ZERO affect on the climate change. 100s of factors are way more important.

  46. The science is not that hard… and the UN is wrong… and they know it. And nothing you showed was any different than trends already established. With NO MASS EXTINCTION due to climate change. Sea levels are rising, but any water added from ice is not the cause. Could be.. yes but they won't be. Unless you just let the ocean in. …… disasters are not becoming more frequent or more devastating. "the dramatic impacts of drought" are not because of climate change but due to laws and misuse of land and water, in which governments need to back off. And 99% of climate scientists don't claim that the earth is "sick." this video is soo full of false narratives. … wait… you just said CO2 is the problem… but suggest that plants that use CO2 to grow cant grow???? FAKE NEWS!!!

  47. If it is true that there is a catastrophic impact in the offing, keeping oil in the ground will not be such an easy thing to do with a world population as large as it is today (and increasing) unless we dramatically convert to nuclear power. More hydro electricity, wind power, solar power, clean gas, and other types will certainly help and I hope we do much more of those, but to significantly replace the enormous amount of energy oil provides, nuclear power seems like the most likely candidate to reduce the impact of climate change in the time frame required.
