How cities are defending themselves against climate change

Some of the most extreme weather events on record took place in 2022, as climate change-induced wildfires and droughts ravaged parts of Europe, the U.S. and Africa, even as Asia battled disastrous floods and monsoon rains.
Experts say this is just the beginning.
“What we calculated and what we knew as, say, one-in-10-year events is now becoming one-in-five-years,” Ana Mijic, professor at Imperial College London, told CNBC.
The world’s cities are at the forefront of those shifts.
Cities play an outsized role in climate change, consuming around 75% of the world’s energy and producing more than 70% of greenhouse gas emissions.
But could they also be part of the solution, being small and nimble enough to avoid the bureaucracy of national politics?
Watch the video above to find out how cities are responding to - and reducing - the rising risks of climate change.

Redesign of cities, in some nations, could have a huge effect !!

[@roberthicks1612]

The real purpose of redesigning cities would be to control the peasants, i.e. anyone (99%) that is not an (1%) elite. They want to take away our rights freedoms and force us to do what they demand. That would indeed have a huge effect.

[@froilananthony7391]

the cities are really to blame of climate change because they are cutting trees instead of planting and build buildings that is not important. Irresponsible mining and illegal logging. It should be balanced and we should be more responsible as citizen, spread the love❤

Climate change is because of human action, not nature. We aren't blaming this on nature, we're blaming humans.

[@roberthicks1612]

@@jeanclaudejunior Thanos did not understand science. Science has proven that any time a species out grows its resources, it reduces its population to the point it can sustain itself. The fact that liberals often claim the human population is too great is another sign they do not listen to real science.

[@pkal244]

Right? If all the millions (billions?) of people suddenly moved to rural areas and the burbs, that would hurt the climate even more. Imagine creating and supporting that kind of spread out infrastructure.

[@distantraveller9876]

@@jeanclaudejunior The universe could be infinite, we don't know. Even if it is finite, there's still more resources than we could ever possibly need. There could be 100 of billions of people on Earth and there'd still be more than enough to go around.

[@dylanbuchman8128]

I feel like the title of the video is really misleading. The modern structures we have designed aren't limited to cities, and the reason cities have such huge impacts on the climate is just that they are filled with SO many people and industries. People outside cities are very much still part of the system though--they work in nearby cities, a majority of their goods are manufactured and processed in cities, and they receive almost all of their goods through commerce that is oriented around cities.

[@CNBCi]

Hi Dylan, thanks for your comment. You are right to say that urban areas represent high concentrations of financial, infrastructure and human assets and activities, hence the disproportion. In fact, there are around 4.5 billion people living in cities today, and that number is projected to grow by almost 50% by 2050. You can see the UN's reports here, which we cited in our video: news.un.org/en/story/2021/10/1101992 unhabitat.org/topic/climate-change

[@roberthicks1612]

Actually, the biggest impact is the fact that concrete and asphalt cause heat islands which distort the temperature changes that are actually happening, making them look like more is happening that actually is.

[@dannyf4447]

Why were dinosaurs so large?

[@distantraveller9876]

Because dinosaurs lived during the Triassic, Jurassic and Cretaceous. During these periods, the climate on Earth was much warmer, with CO₂ levels over 4x higher than they are today. This caused plant life to flourish, which caused herbivores to grow, partly because there was enough food to support them. As a result, large carnivores like the T-Rex also had to grow in size just so they could feed on the massive Sauropods. Ironically, their size was their biggest downfall as the only animals that survived the K-Pg extinction event were mammals and smaller dinosaurs, which eventually evolved into the humans, birds and reptiles of today.

You can’t do that on third world countries, it is gonna cost lots of money and they are the ones who suffered the most

[@knarftrakiul3881]

No one really denying climate change. Just that it's not because of humans. All it takes is one glance at the voltesk ice core sample chart and you will see the earth has been through 4 different ice ages in last 500K years and in between each ice age there are warming periods where CO2 levels rise and temperature rises and melts back the ice and glaciers. Currently on this chart we are at the tail end of a warming period from last ice age

[@roberthicks1612]

The only thing wrong with your statement is wording. Your right about most things, but the reality is we are in an ice age that began millions of years ago, and what you called ice ages were "glacial periods" where glaciers advanced. The period we are in now is called an interglacial period. Our current interglacial period is called the Holocene period. Hope this helps you.

[@rps1689]

Natural forcings are in a cooling phase. You do know that the last few glacial periods in the Pleistocene were synchronous with the 105,000 year precession cycle. They're in a cooling phase right now yet we are not in a global cooling trend due anthropogenic warming; the current rapid increase in CO2 is manmade.

[@roberthicks1612]

@@rps1689 There is no evidence of that, save a much debunked graph by Michael Mann. The problem is that the graph is derived by an algorithm that no one buy he has ever seen. That is not proper science. Every interglacial period has alternating periods of warming and cooling. According to Michael Mann, this interglacial period (called the Holocene) is the only interglacial period in history to have no warming or cooling periods. According to him (and no one else) the Holocene has had a steady, regular cooling for 8000 years, with no ups, just a gradual cooling. REAL scientist say that the Holocene has had it share of warming and cooling periods, including the little ice age. We are in the natural warming phase following the little ice age. In every interglacial period, warming periods last as long as the cooling period that preceded them. The little ice age lasted about 500 years, so its unreasonable to think we recovered from it in less than a century. Once again, any computer model that says the climate sensitivity to co2 changes is greater than 1°c per doubling was off after only a decade and everything that says it was greater than .5°c per doubling is off by a half degree in 20 years. What they did was created about a hundred models and each model predicted different things, like an increase in hurricanes, or a decrease in hurricanes. As a result, anything that can happen is predicted by one model or another. SO when something happens, they can point to the one model that predicts this event and say "see, our models are all right". There is not one model that predicts all of it, but all of them are wrong, except the models that says co2 has little effect on the climate. It predicts that weather patterns will remain the same and they have.

[@rps1689]

Note rubes like to bring up Mann's 1998 work, which, is irrelevant today, since it's been corroborated so many times by teams who were trying to bust it. Superseded half a dozen time by more comprehensive investigations. Different lines of evidence, different statistical techniques. Same results. He’s moved on to other topics. 
Funny how many don't you know about any of the other "hockey stick" papers. “Climate skeptics” love to bring up those warm and cold periods they put so much stock in. They're blips compared with climate change during the industrial era.
