Dear viewers,
we would like to clarify that our guest, Trinidad Fernandez, has been incorrectly introduced as a member of the International Climate Initiative at the German Environment Ministry. In fact, she is the Head of Urban Economy Innovation at Fraunhofer Institute for Industrial Engineering IAO in Stuttgart, Germany. We apologize for any confusion this may have caused.
Trees, water fountains, little green islands.
Yes, and cutting CO2 emissions asap.
I have an old friend who has a 2,000 sq/ft home where it gets hot in the summer and decades ago he planted appropriate trees for shade. He has never installed A/C and even on the hottest days(35 C +) it always stays comfortably cool. To this day it still amazes me how well this works.
Maby not build a city out of stone, glass and concrete. Plant more trees / shading.
even solarpanels that can cover shading might be nice. As in making a roof
That's the reason I reject solar roof tiles. If I have a panel, say, 10 cm above my roof, it will shade it, hence the roof itself would be cooler.
Phoenix is in a desert. Always has been. Its water is pumped from out of state.
Every home and business should install a rain water collection and storage system along with solar panels.
Even in areas where rain is infrequent it is crazy to waste the little rain that does fall and waste it.
We need to stop planting green lawns and switch to local native plantings around homes.
It is crazy to plant lawns and build golf courses in dry desert areas. We waste too much water and electricity.
It's easy to say every home should install solar but solar is expensive and not every home can afford it.
I would love to install solar on my roof but it's just too expensive.
Ancient Dessert Freezer Domes
The solution is to build those underground ancient Persian dessert freezer domes. No electricity or technical moving parts required, just let nature do its thing. ☀️🥵🛕🧊🥶
Dessert as in 🍨 not Desert 🏜️.
Rule number 1: less concrete more plants
Do you want to beat the heat, come and holiday in the U.K. where temps barely rise above 60°F and night time temps in their low 50s.
Wow really?
London Fog is real and so cooling
Then comes the caveat, there hasn't been a dry day since the start of July (at least here in Belfast)
@@Dash8Q400Channel and in new englad half the year was rain, a chance of rain and about to rain. when we are done with it we send it to the UK
Don't use so many ACs... In hospitals and similar institutions, yes. Everywhere else not. ACs are heating up the streets even more... And even more Electricity goes to waste, just so that people can freeze in their homes. As many do, instead of setting the temperature a little under the outside, they set it up under 20°C. Now imagine the power draw when the AC has to cool the difference of 15 degrees? And multiply it by the number of ACs in the city...
When it's 115 degrees, that's easier said than done
@@TheNilla2020 no. its easier done than said. plenty of countries with hot temps don't use AC at all
Even 28°C is fine with a good Fan for Wind.
People are used too much to their modern comforts and won't go without them, I realize I'm one of them, since I won't give up my car. However I've spent all the summer without a/c, just relying on fans and cold foods.
WEF and Governments through their Environment initiative have already decided to change AC. You will no longer cool lower than 20 degrees ambient.
Isn't the real problem with heat waves the agriculture, the food production? Or are plants more heat resistant? Somehow, I don't think so.
Depends on the plants i would guess and within which stage the heatwave takes affect. So is it something that likes a lot of sun or does rather prefers a bit of shadow. How much water does the plant needs and is that affected due to the heatwaves. If it is right at the start when the seed it planted, when the seed first spreads, to late stage when the fruits developing ... . Generally speaking, the hotter they become, beyond certain spectras within wich the plants develop optimally, then less gains can be produced and sold by the farmers. Sofar we do have overproduction in terms of food in the past decades, but especially in wealthy countries also with lots of food waste which to me sounds like an oxymoron.
Last year though in asia, especially China, the heatwave and drought did criple food production. Now the Ukrain war is also relevant in that aspect. As doesn't matter how much is produced, if it can not get shiped to where it is needed.
@@kinngrimm in several areas, like West India and parts of African countries climate migration is because of drought. Therefore, the issue with agriculture should be a part of all these discussions about heat waves, flooding summed up as climate change and I do not see the attention by the media.
@@ANIMALS_AND_MORE_moments Fully agree, mitigation, adaption and maybe reversal of climate change if not a new balance would be found are all aspects on how to react on climate change.
Been telling for a few years that we need more and better seawater desalination plants.
stop using electricity
Only good way to beat heat is air con or swimming pool. Thank me later. Regards from down under
Air Conditioners heats up the world from the exhaust.
summer temps wasnt harsh in the Toronto area. Only the wildfire smoke and smog in late May to June
nice here in NM. Normal summer.
Trees, green roofs can reduce heat. Insulating paint on building to reduce urban heat island.
easy. plant more trees. unpopular move ofc. works 100%
Greenery. Plant Vegetation everywhere possible.
I am glad Singapore thought of it decades before.. all that concrete and no trees is a problem.
or they can do what some Japanese do, they have a practise of splashing some water on the roads or pavement to cool it down, when the water evaporates it causes humidity for rain also, of cos many hundreds of thousands of ppl need to do that as a whole..
Meanwhile in Northern Europe it’s been cool grey and showery for the last six weeks
Which clearly shows there is no climate change at all right? Nevermind that it's absolute bulsh*t to walk in long sleeves in early August or scorching fires in Greece. Few weeks of abnormally cold summer in your area makes it all fine and dandy.
What is the app they use in the clip?
Use cloudbuster to control city temperature
There's always 🍧, 🍦& cold 🍻! 😁
At least now the trees is causing Singapore to be much "cooler" at 32 or 33 deg C than in USA or Europe.
Kuala Lumpur has more parks too
keep city cool with less asphalt and more trees. have you heard of them? apparently they have been on earth for a long time and they cast shade and can bump real estate value up a notch
It's trees. It's trees and fewer cars!
If its warm i would go into my living room in the house
Open the front and back door to create a draft
Its great
More parks trees and green.
Its amazing how life comes to a slow down in Europe..meantime in Africa and India, life continues as normal even in the heat
Because india and Africa has got what it takes
@@gokulkrishna4011 Because Europe is further North and in a colder climate. What's amazing about that?
@@CausticLemons7 The world belongs to the people who can thrive in a warmer world
@@gokulkrishna4011 Unless it gets too warm then those places become desolate and cannot support human life. Please do not try to compare suffering, or act is if global climate change is a competition to put down others.
@@CausticLemons7 Brother i truly thought this climate change can be stopped and i even wanted to help in stopping it. Thats why i even took masters in environmental science. Then i realized that environmental sectors are underpaid and the number of jobs are very low. If environment was truly important then people must be paid more in order to save it . else let it break apart . Only if environment breaks apart will environment sector gain importance . Let it break faster .
Just visit any Australian city's to find out how to reduce temperature, 😅
Reducing our consumption of meat and fossil fuels can go a long, long way.
We won't keep our cities cool, I'm sure about it.
We will all move into tree houses mate...😂😂
@@Ryan-lx6oh I think caves would be more appropriate 😁😁
@@lolitaras22 I like that idea mate get back to our roots. 😁😁 (Cavemen are cool)
But personally I'm a more treehouse type of guy.... Haha!
Let's see. Coal, Natural Gas, and Oil. That's how!
Only lockdowns of people that have more than 1 car
I feel like im in another world. This year June was the coldest June on record for my state and it was hot through nearly all of July but the past few days feel relatively cool. The previous years have all been scorching hot all the way back in May. Sometimes as early as March. This has definitely been the coldest Spring and Summer I ever had personally.
Also all the concrete, glass, and metal makes everything so hot. Parking lots here in the states are terrible. Areas with vegetables feel significantly better but way to many bugs. Being surrounded by vegetation and on concrete is normally the best bet in my opinion.
We humans have dealt with huge climate changes over our entire history. In the past with significantly less knowledge and ability to survive such shifts. It wont be fun but humans will het through this. Currently I think we need to change the way we think. Dress for the environment, drinks lots of water, build better buildings. Relying so much on Air Conditioning and not investing into buildings that can self regulate to a extenet seems like a waste. Society will not collapse because of Global Warming like some people say.
chill, furry finn
@C-lp6jb Ever heard of the clientele changes of the Sahara, the Ice Age, the various Volcanic eruptions? Yeah we have dealt with various climate changes and environmental changes. Still here

why people live in big cities in the first place?
Concentration of economic activity. It's great to live in a city that is built well but even bad cities provide a lot of income potential.
@@tylernorby4939
you didn't answer my question you've just explained it more.
Paint all the asphalt white
Plant trees.
Plant more trees
The male presenter's voice reaches an uncomfortable high pitch. He needs vocal training.
God bless American
Hey, when will you talk about the real company Cannafarm Ltd that brings profit?
Paint every roof white.
If instead of criminalizing public urination, it was celebrated, nay made compulsory, the evaporative effects would cool all cities up to 2-3%.
Now who will criticize Latin América for conserving more acres of jungle rather than destroy it. Sorry, and hope you plant more trees.
👍
Can you guys have journalists with better accents?
Maybe we (corporations too since they are people), could all stop destroying the planet? Just an idea...
Someone need to create white roads thats get clean on raining days but have same friction and wear and tear.
By moving the Sun somewhere else maybe??? Oh but wait only Allah the Almighty One is able to do this because the Sun and everything in this world belongs to him ☝🏼
How to keep city cool,? come to United Kingdom 😅
Wait, do you think cryptocurrency will crash? I dont think so. More and more companies are integrating cryptocurrency into their operations: Amazon, Cannafarm Ltd, Burger King, even Starbucks, dude!
This thread has changed into a crypto echo chamber, hamber, amber, ber, ber...

I find it hard to believe that 62,000 people died from heat in 1 summer in Europe
Use water cannons
If only there were a technology, that could keep people cool in hot weather. Somebody should really invent that.😅
And what are we going to do with all the crops wilting in the sun? Can't give a/c to all of them all over the world.
It was like this 50 years ago. I feel tarded by these informations. Are we worshiping our stupidity?
Kaliyuga has arrived.
Kaliyuga is over bro.
Who would have thought concrete and glass makes for uncomfortable living conditions in hot weather. PLANT MORE TREES IN CITYS GODDAMMIT!!!! The stupidity of city planners always amazes me.
“Heat stressed Americans?”
Homie we have AC here. Y’all are the ones who lose 60k people when temps hit what we think of as “a bit warm” 😂
