I hate myself for saying this but the problem with this video is that people in the west are now used to seeing people in developing countries suffer. Impacts on western life would probably have more of a punch.
-
If human behavior is predictable, then a 3 degree world is inevitable...
-
Video is 2 years old....and there has STILL been no significant governmental action.

I'm 26 years old now. Just 10 years ago I hardly saw our (Bangladesh's) temperature cross 30°C. It is 2024 now and our temperature is crossing 40°C regularly.
-
World leaders should try to have their climate summit at the slums of climate refugees in Bangladesh, that should bring home the reality.
-
A point none of these informative mini-documentaries miss out on mentioning: Average Global Temperatures during Ice Ages were merely 3-6 Degrees Celsius lower than they are today. A relatively small difference in global heat energy levels has a HUGE impact on the planet.

As a Kenyan i really feel because drought will be increasing in my country yet the situation is already bad

I live in Luxembourg and climate change is really noticeable here. A few years ago, during the night temperatures would drop to about -10 degrees Celsius, but now they barely drop to -5 degrees Celsius during the night. Also, snowfall would be very frequent and the snow could last for days, but now it is much rarer and even when it does snow quite a lot, the snow melts after a few hours.
-
It might help to actually hold COP conferences in the global south in the summer so the delegates could actually feel the heat. Instead of Glasgow in November, how about Amman Jordan in July?

When I was young, I would experience snow almost every year. Our garden would be a white winter wonderland on Christmas Eve. I would play in the snow with my father for hours. This was 30 years ago. Now it has been 5 years since we’ve last seen snow in the winter. The snow has been replaced by rain. Every year I keep hoping for that white wonder to return so that my children will get to experience that pleasure. This is just a mild change in comparison to the disastrous other consequences of climate change, but it still has a noticeable impact on people’s well-being.

The exponential function is occuring, no more linear change.

I'm from Republic of Sakha, it's placed in Far East of Russia, near the Arctic Ocean. In the last few years, summer become more and more heater, wildfires throughout The Taiga forests are almost an ordinary things 😢

My mom is 73 and grew up in Mexico. She says she remembers how cold it was when she started going with family members (from childhood to teens) to the cemetery on November 2, Day of the Dead. She's also noticed how hot it's gotten the longer she's lived.

My grandpa told us that it used to snow in winters regularly in Uttarakhand at an altitude of about 800 meters a few decades ago. My father told me the same for some villages at 1400 meters some years ago. And now we don't see snow even at 1800 meters every year. Our village is at 1900 meters. We're worried for our apple, apricot gardens that wouldn't yield as much in near future.
-
We're not scaring people nearly enough. Most people just think it will be someone else's problem or they think someone will figure out how to mitigate the problems and life will go on as usual.

I can't speak for other parts of the world but here in Phoenix we've had tremendous growth over the last twenty years. The city is spreading out into the desert. That means more paved roads, parking lots and buildings. This creates a heat dome or a heat island effect. Maybe it would be better for urban growth to go vertically instead of horizontally. The City of Phoenix started its Cool Pavement Program a couple of years ago. I'm hoping this program will mitigate the effects of our urban heat island.

When I was 8, climate change issues was already discussed. Now, I am 28, the same issue is still being discussed.
-
I haven't had a summer in 5 years. The fires here in Oregon have burned cities to the ground in just hours last year. We can not go outside in those months of summer for the smoke, and still homes are taken. I'm not happy at all anymore. And this is NOW!

I am from Romania and I have noticed many changes 😢 It started to stop snowing in the winter and the summers became much warmer. I'm turning 20 this month and I remember winters and summers being normal when I was a kid. I can't imagine how bad it will be in a few years. I wish so badly I could do something. It devastates me that most people are ignorant. It also annoys me and makes me lose hope in humanity. Our future is destroyed. We should stop having children so they don't have the same fate.

Seeing the world leaders flipping coins wishing for a solution in Scotland... I guess I know what our future will look like 🤡
