Who Is Responsible For Climate Change? - Who Needs To Fix It?

This video is part of a series about climate change supported by Breakthrough Energy - a coalition founded by Bill Gates, that is working to expand clean-energy investment and support the innovations that will lead the world to net-zero carbon emissions.
Also a special thanks to the team at Our World for helping us out with data and research!
Sources & further reading:
Since the Industrial Revolution, humans have released over 1.5 trillion tonnes of carbon dioxide or CO2 into the earth's atmosphere. In the year 2019 we were still pumping out around 37 billion more. That’s 50% more than the year 2000 and almost three times as much as 50 years ago. And it’s not just CO2. We’re also pumping out growing volumes of other greenhouse gases such as methane and nitrous oxide. Combining all of our greenhouse gases, we’re emitting 51 billion tonnes of carbon dioxide equivalents each year.
And emissions keep rising - but they need to get down to 0!

    Climate change is a hoax. It's being used to implement communism. Mark my words, in 20 years nobody will have freedom. Big government will decide what and when we eat, drive, drink, how we work and much more. This video is so crap. Example Iran a country that still is burning coal to heat homes with a population of over 70 million has a pollution of only 5%... Need I say more?



      3 dagen geleden

      @Pepijn Did you read the IPCC report? I did and I can't find anything about the 96% of scientists agreeing on how climate change works. What I do find is that big green gets more money when they talk about all these doom scenarios. The fact is that the climate is always changing and it will always do so and we don't yet fully understand the dynamics of how climate works on this planet. Those are the fact. Not one thing in this video is fact. It's all fiction.

    • Pepijn


      3 dagen geleden

      Those large contributors aren't contributing so much by heating homes, but with large scale industry. Iran does not have as much industry, hence they contribute less. This is also why Germany has historically produced as much as the whole of Africa and South America combined. Which would be ridiculous if it was only by heating homes with coal, Germany does not have that many people. Germany does however have a huge manufacturing industry.

Where as just before in 1st context the flag was right and later you decided to change India's flag...

    Not blame, but cooperation; To help the earth I decoded this message; The wow signal frequency of 1420.4058 MHz, is exactly the same frequency as Cold Hydrogen Gas atoms emitting photons at the wavelength of 1420.4058 MHz; the message is for the earth to start using clean and safe hydrogen gas for all human consumption, and stop destroying our environment and natural planetary defense mechanisms. I thank The Lord for this breakthrough, as I did not know that the world is headed for a major catastrophe. When a wow message from outer space translates for the planet's future security, it's time to act, as I have said, the greatest climate change initiative would be to start using safe and clean hydrogen gas for all human consumption. The earth will heal itself, but as the human body, it can only heal at a rate that is proportionate to the pollution that is going in the atmosphere, or in our case, in our bodies. If the pollution exceeds the healing time necessary for the planet, as our bodies, the planet will continue to decay proportionately to the ratio of pollution put into the atmosphere, because it has no time to heal from our pollutions. The great news is, the earth heals itself if we would stop the toxic emissions into the atmosphere.

    So the solution is, developing countries need to buy the 'clean' tech from rich countries to make themselves clean, at the cost of higher energy price and possible slowed down development? In the mean time developed courtiers got another chance to use the price scissors to reap even more profit from the poor countries? If the developed countries really cared about this and making the world clean, they need to pay for their historical pollution with cash and set up an international fund to provide FREE clean energy solutions to developing countries.

    It's amazing that as glaciers retreat they uncover evidence of prior human occupation. So as temperatures hit the highest temperatures on record we find evidence of people living where glaciers currently exist. CNN just reported that a glacier retreated uncovering a ww1 bunker. How can a retreating glacier uncover human occupation from a 100 years ago if the temperatures have never been so high?
