Floods, heat waves, droughts, and megafires: all are phenomena linked to Earth’s changing climate. People hear about climate change all the time, but how well do they know the evidence?
This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years. Along the way, we meet scientists working at the forefront of climate change: fire scientist Crystal Kolden, soil scientist Asmeret Asefaw Berhe, atmospheric scientist Ralph Keeling, and ice core scientist Kathleen Wendt. The scientists explain how we know what we know about Earth’s changing climate and make the critical point that we can solve climate challenges.

@A11A111 You hit the nail on the head. For decades we have spent billions looking for technical, “scientific “ solutions. When the answer has been in front of us.
I wish I had a solution on how to sustainably manage population growth.
Wait a sec…how does the graph they show at the 11 minute mark prove temperature rises are correlated to co2 levels? If you look there were huge temperature spikes 850-750k years ago when co2 levels were much lower than they are today.

There is no climate change it is all just to bring in the new world order
Wrong, humans are raping the planet in search of profit and power.
why nobody talks about nuclear? it's part of the solution and without it we might not make it as a species in a long enough horizon
Love this channel, thanks for educating us. Subscribed!
Scientist here. This was well done, initially. The recommendation to "transition to renewables" and "use soil to draw down CO2" comes to us straight from the fossil fuels industry. I will allow for the moment that this was an oversight, but do know the fossil fuels sector is promoting the continued use of their products combined with some vague promise to "fix it later, somehow, a century from now". This advice is lethal for life on Earth, human life included. The only practical solution is to leave all fossil fuels in the ground for all time.
OK stop, video paused at 1 minute 51 second, forest fires in the US are insignificant when compared to deforestation but the US ignores deforestation, in fact, I don’t believe the word ‘deforestation’ in in their dictionaries. Also, the pronunciation of ‘anti’ is not correct by the US, you do not pronounce the ‘i’, it’s just ‘ant-tea’ not ‘ant-i’. It just makes you sound thicker when you pronounce it wrong!
Remember, the calendar has had a day added in February, for the leap year, for years, so we have moved the calendar so that it does not line up with the seasons anymore. At a minimum, we need to move two months from the beginning of a new year, to put this back to a reasonable alignment with the seasons!
Most of the issues around global, have been caused by the US but the US has it’s ears covered and it’s eyes are closed and they are not recognising the problems they have produced. Why do most American homes leave their lights on all day, it costs to produce the electricity to power these lights etc, yet in films, documentaries, visits to American homes, the light are always on. So the pollution from the power stations is causing the CO2 levels to increase but with the US’s arrogance, they are pointing their finger to other countries!
Just watched this again and at 0:55 he states that humans are have a profound impact on the planet but what he doesn’t say is that the Americans are have the highest profound impact on the planet, there’s a difference…!
PY attention. Thank you
Thanks you really helped me do my college report on climate change.

A recent UN report found that the richest 1% of the world population account for 15% of emissions. the richest control the Fossil fuel companies, transportation and mega factories. They are not stopping their energy usage nor are they doing much to spur the movement toward sustainability.
CO2 is driven by temperature in glacial cycles, not the other way around (warmer oceans expel CO2)…. Correlation is not causation and if there is target fixation, then other variables won't be considered… A better approach would be to look at historic events in the geologic record, rather than making predictions – the PETM event 56M years ago is a better way to look at the current situation. There was approximately 30 times the increase of CO2 in the atmosphere compared with what humans have released and temperatures rose 5-8C…. From this you can see that while CO2 would have an impact (say 0.25C) , there must be other factors to contribute to a 1C rise (ie land clearing and natural variations)
I was forced to watch this for a grade.
But then, the transition required to reduce co2 production also requires burning to create these renewable technologies for the sustainability of our environment. I think, the most effective way to actually reduce co2 production is to rest from the undustrial-technology era. We must give more improtance in the life of our planet,Earth, than the comfort we can experience living here in the planet. Let us not be selfish for we are not the only human beings to experience life and therefore we must share it's beauty to the future generations by being careful of everything we decide now.
Loved it 👍🏻
2010 was the hottest decade. Why can't these under educated people do their homework. Oh that's right they would rather cause fear and panic.
They skip over the amount of solar radiation hitting the planet say it hasn't increased "significantly" over the last ten year to cause climate change. Like it couldn't be an accumulative effect – it has to be immediate. I don't believe that. Heat accumulates in a body. The Milankovich cycles and the drop in the Earth's magnetic field could have an accumulative heat build up as most of the solar radiation hits our oceans causing the most prevalent greenhouse gas in the atmosphere, water vapor, to increase. There are so many holes in this "climate change" theory, you could drive a planet through it.
The hottest decade ever???? How could they possibly know that??
The good news about global warming is that it’s not being caused by increasing solar output or any other natural cause, and also that mankind generally understands that it’s the ‘amplified greenhouse effect’ which is the source of increasing temperatures. With this in mind, it behooves us to rapidly advance and apply our scientific knowledge to the point that burning fossil fuels to produce electricity will become as antiquated as burning whale oil for light.
Quote: “Anxiety must go. It must be replaced by faith and solemn confidence in the outworking of the divine plan.”
Note: As sunlight (photons) is warming the surface of the Earth, surface heat energy is also radiating away from our planet in the form of ‘infrared radiation’ which passes freely thru the atmospheric gases of nitrogen and oxygen that do not absorb heat. Indeed, if it weren’t for greenhouse gases such as carbon dioxide that ‘do interact’ strongly with infrared energy and ‘impede the escape’ of Earth’s radiant heat, then the planet would be perpetually frozen solid. Thankfully, even though greenhouse gases comprise only 4/10ths of one percent of the atmosphere, they are so powerful that they maintain a ‘blanketing effect’ by constantly ‘absorbing and releasing’ the infrared heat energy over and over, again and again. In doing so, they gyrate wildly, thus causing them to vigorously collide with other atmospheric molecules which, in turn, collide with other air molecules, imparting the kinetic energy of motion throughout the atmosphere — and this vibratory state registers as temperature.

I had goosebumps throughout the video, let's work together guys ❤
Rather than explaining that temperatures have risen because the amount of carbon dioxide has increased, I think it would be more convincing to explain that CO2 and CH4 vibrate due to solar radiation.
As a result, they retain thermal energy for a long time.
Unlike a struck cymbal, vibrating CO2 can continue to vibrate for a long time with almost no friction.
When you add in the image of CO2 flowing into the Arctic released by a NASA agency, you can imagine that the Arctic has warmed several times.
After all, the North and South Poles are constantly exposed to solar radiation in the summer.
I do not beleived and climate changed.
