Dhruv Rathee - Extreme Heatwave in Canada ｜ 50°C Temperature ｜ Cl..
As unbelievable as it sounds, a village for lytton in the state of British Columbia in Canada registered a record breaking temperature of almost 50°C last week. The fact that this comes as a big surprise is because Canada is one of the coldest countries on planet. Experts blame a heat dome as the reason behind this but the real cause is climate change. I explain how the extreme weather patterns are increasing in all parts of the world because of this, which means summers will become hotter and winters will become colder. And what can we do to stop the climate change?

00:00Namaskar, Dostam!
00:01Waise toh Canada ko duniya ki one of the coldest countries mein consider kiya jaata hai.
00:04Waha par minus 20-30 degrees tak temperature jaana aam baat maani jaati hai.
00:10Lekin pichle kuch dinon me itni bhayankar heat wave aayi hai Canada mein
00:14ki kuch areas mein Canada ke temperature plus 49.6 degrees tak pahunch gaya.
00:20Yani almost 50 degrees.
00:22Itni buri garmi toh aaj tak Delhi mein bhi nahi hoi hai kabhi.
00:2550 degrees ka temperature aap aam taur par Dubai ya kisi Middle Eastern country mein expect karoge
00:30lekin ab ye Canada tak mein dekhne ko mil raha hai.
00:32Kaise possible ho gaya ye?
00:34Aayiye jaanne ki koshish karte hain aaj ke iss video mein.
00:39Specifically uss jegahin ki baat karte hain jahaan par ye temperature ka record toota hai.
00:43Canada ki ek state hai British Columbia.
00:45Canada ke South West mein hai ye.
00:47Is state mein ek gaon hai Lytton naam se.
00:51Ab ye latitude dekhoge agar aap iss gaon ka, ye 50 degree latitude par aata hai.
00:55Yani London ke latitude ke barabar hai.
00:58Toh jitna North mein London hai UK mein,
01:01utna hi North mein ye Lytton gaon hai.
01:04Ye fact isliye jaanna zaruri hai kyunki aap equator se jitna door North mein jaate hain aam taur par
01:09utni hi zyada thand badh jati hai.
01:11Zyadatar logon ke gharon mein, iss gaon mein AC nahi hai.
01:14Kyunki iss area ka climate jo hai mild climate hai.
01:18Ye table dekho, isme aapko bata rakha hai ki kis mahine mein
01:21aap kitna temperature maximum minimum on average expect kar sakte ho iss gaon mein hoga.
01:26Toh July-August ke mahine mein maximum temperature on average 28 degrees expect kiya jaa sakta hai.
01:32Halak hi yaha par jab garmiya aati hain toh kai baari aesa zarur dekha gaya hai ki temperature 40 degrees paar kar chuka hai.
01:39Lekin sardiyon mein yaha par minus 5, minus 10 bhi jaa sakta hai aur infact record minimum temperature yaha par minus 31 degrees bhi jaa chuka hai.
01:46Ab isse aap Delhi jaise shahar se compare kariye
01:48kyunki Delhi mein itni buri garmi padti hai ki 45 degrees toh bahot baar dekha gaya hai.
01:53Lekin Delhi ka all time temperature ka record hai 48 degrees.
01:57Toh Canada mein ek gaon ne isko bhi beat kar diya.
02:01Ye garmi itni intense thi ki power cables melt ho gayi.
02:05Jo sadke thi, wo toot gayi iss garmi mein.
02:08Kyunki zyadatar logon ke gharon mein air conditioning nahi thi
02:11toh log shelter lene ke liye public places mein gaye jahan par AC maujood tha.
02:15Kuch log raat bhar apni gadi ke andar soye AC on kar.
02:19Lekin ye sirf kuch chand dino ki hi baat thi
02:22kyunki uske baad is heat wave ki wajah se side wale jungle par aag lag gayi.
02:26Ek wild fire aa gayi is gaon mein.
02:29Aur is wild fire ne 90% gaon ko burn down kar diya.
02:33Jala kar raakh kar diya.
02:3590% gaon aaj ke din ye completely destroy ho chuka hai.
02:39Kuch aesi aap inki photos dekh sakte hain.
02:42Is extreme weather event ke peeche experts climate change ko root cause batate hain.
02:47Lekin technical shabdon mein kaha jaye toh ek heat dome ki wajah se ye hua hai.
02:51Technically ye baat kari jaa rahi hain yaha par.
02:54Matlab, garam hawa jo thi wo aamtaur par upar rise karti hai.
02:58Jo atmosphere mein high pressure maujood tha.
03:01Situation create hoi thi high pressure ki.
03:03Wo high pressure is garam hawa ko wapas neeche push down karta hai surface ki taraf.
03:07Aur kyunki ye garam hawa wapas neeche push down hoti hai,
03:10ye aur denser banjati hai compress ho kar aur aur garam banjati hai.
03:14Kai jaghaon par jab aap iske baare mein padhne ki koshish karenge
03:16toh kuch log sirf aur sirf heat dome par hi blame daalte hain.
03:20Lekin sachayi ye hi hai ki climate change ki wajah se aise extreme weather events
03:24aur frequent banjate hain.
03:26Yani zyada hone lag jate hain aur aur extreme banjate hain.
03:30Aur intense ho jate hain.
03:32Aksar kai logon ko ye misunderstanding rehti hai global warming ke baare mein.
03:36Ki global warming ho rahi hai toh garmi zyada badh jayegi.
03:39Lekin hamesha iska ye conclusion nahi nikala jaa sakta.
03:41Kyunki climate change se extreme weather events badhte hain.
03:44Iska matlab ye hai ki garmiya aur zyada garam hoengi.
03:47Aur sardiyon me aur zyada thand padh sakti hai.
03:50Aur aise unexpected weather events.
03:52Aur natural disasters.
03:53Inki frequency badhegi aur ye aur zyada severe ho jayenge.
03:57Michael Mann, ek atmospheric science ke professor hain,
04:00unka kehna hai ki heat waves ki frequency hai,
04:03wo teen guna zyada badh chuki hai aaj ke din.
04:05As compared to 1960s.
04:07Aur jo record breaking hot months hume dekhne ko milte hain.
04:11Unki frequency paanch guna zyada badh chuki hai.
04:13As compared to agar climate change nahi hua hota.
04:172015 ke famous Paris Climate Agreement me,
04:19jisse almost 200 desho ne sign kiya tha.
04:22In countries ne pledge kiya tha ki agar hum pre-industrial level se compare karein toh.
04:26Yani 1850 se leke 1900 tak ka jo time tha.
04:29Us samay se agar compare kiya jaye,
04:31global average temperature ko
04:332 degree se zyada rise nahi karne diya jayega.
04:36Preferably, 1.5 degree tak hi rakha jayega.
04:40Jitna zyada average temperature badhta hai dharti ka,
04:43utne hi zyada ye extreme weather events
04:45hume zyada dekhne ko milenge.
04:47Ek-ek degree ke zyada hone se,
04:49badhe bhayankar effects dekhne ko milte hain.
04:51Jab main chhota tha, bachpan mein global warming ke baare mein padhta tha,
04:54mujhe lagta tha ki kya badi cheez hai?
04:561-2 degree se agar temperature badhega poori dharti ka,
04:59kise farag padna hai?
05:01Sahe lenge, 2 degree hi toh zyada hai.
05:03Lekin reality se kahi zyada khatarnak hai, dosto.
05:06Kyuki inhi 2-3 degree ke rise se,
05:09ye extreme weather events exponentially badh jate hain.
05:12Garmiya bohot zyada garam ho jate hain.
05:14Heat waves aane ke chances bohot zyada badh jate hain.
05:17Jo tornadoes aur floods aate hain,
05:20droughts aate hain,
05:21inke chances bhi exponentially badh jate hain.
05:23Biodiversity ko bohot khatra pahunjta hai.
05:26Exactly kitne degree ke rise se
05:28kya asar padhega dharti par,
05:29iski baat kisi aur video mein karunga detail mein.
05:32Kyuki bohot kuch hai uske baare mein bolne ke liye.
05:34Lekin abhi main bas itna batana chahunga
05:36ki compared to pre-industrial levels,
05:381 degree already badh chuka hai temperature.
05:41On average, agar dharti ka dekhen toh.
05:43Lekin zyada interesting cheez jaanne wali ye hai
05:46ki ye temperature rise hai,
05:48ye dharti ke har area mein equally nahi ho raha hai.
05:50Kuch mein zyada ho raha hai, kuch mein kam ho raha hai.
05:52Aur Canada ek aesi jegah hai
05:54jahaan pe ye zyada dekhne ko mil raha hai.
05:562019 mein average temperatures
05:58Canada mein 1.7 degree se badh gaye the.
06:01Between 1948 and 2016.
06:04Agar hum Northern Canada ki baat karein
06:06toh wahan par ye temperature rise
06:072.3 degree se already ho chuka hai.
06:10In fact, 2015 ki ek study ne bataya tha
06:12ki pahadiyon mein, jo mountainous areas hote hain
06:152000 metre ki upar ki height par
06:17wahan par global warming ka aasar
06:19zyada dekhne ko milega as compared to lower elevations par.
06:2275% zyada fast hogi wahan par climate change,
06:26global warming, niche ke comparison mein.
06:28Solutions ki baat karne se pehle
06:30ek aur misconception ko main aapar clear karna chahunga.
06:32Kuch logon ko shayad ye 49 degree Celsius ka temperature
06:36dekhkar lagega ki
06:37kuch healthy aur fit logon ko ki
06:39kaunsi badi baat hai?
06:4050 degree bhi hoye hum seh lenge.
06:42Hum toh bade healthy aur fit log hai.
06:4350-52 bhi seh sakte hain hum toh.
06:46Lekin agar main aapse kahu, dost,
06:4835 degree Celsius seh zyada ka temperature bhi
06:52kuch conditions mein
06:54har tarahe ke insaan ke liye jaanleva ho sakta hai.
06:57Sunke kaisa lagega aapko?
06:59Ye sachayi hai, dost.
07:00Kyuki humidity ek bahut important factor hai yahaan par
07:04jisse consider kiya jaana chahiye
07:05jab hum temperature ki baat karte hain.
07:0735 degree temperature at 100% humidity
07:11deadly ho sakta hai
07:12chahe aap kitne bhi fit aur healthy kyun na ho.
07:14Toh baat asal mein yeh hai, dost,
07:15ki garmiyon mein hum sabko pasina aata hai.
07:18Pasina aana humari body ka tariqa hai
07:21apne aapko thanda rakhne ka.
07:22Kyuki jab pasina aata hai hume,
07:24wo evaporate karta hai garmi ki wajah se.
07:26Aur evaporation ke process ki wajah se
07:28humari skin thandi reh paati hai.
07:30Lekin agar hawa mein 100% humidity maujood hai,
07:34toh uss pasine ko evaporate karne ki jegah hi nahi milegi.
07:37Kyuki hawa already saturated ho chuki hai
07:40jitne bhi water vapor ko wo rakh sakti hai apne andh.
07:43Toh wo evaporation hi nahi hogi
07:45toh humari body apne aapko cool down hi nahi kar paayegi.
07:48Technically baat karein toh
07:49yahan par wet bulb temperature term ka istimaal kiya jaata hai.
07:52Yaani wo lowest temperature
07:54jo evaporative cooling ke dwara achieve kiya jaa sakta hai.
07:5735 degree se zyada ka wet bulb temperature
08:01jaan lewa hota hai.
08:02Yahi reason hai, dosto,
08:03ki Dubai aur Rajasthan ka 45 degrees
08:06jahaan par dry heat hai
08:08jahaan itni humidity nahi hai hawa mein
08:10wo zyada bearable lagta hai
08:12as compared to kisi beach kinare
08:14Kerala ka 40 degrees.
08:16Anyways, yeh batane ki beeche mera purpose yeh tha
08:18ki scientists predict karte hain
08:20aane wale time mein, climate change ki wajah se
08:22hume duniya ke kuch areas me
08:2435 degree se zyada ke wet bulb temperatures
08:27dekhne ko mil sakte hain.
08:29Juki literally human life ke liye jaan lewa hai.
08:31Climate change ki against fight karne ke liye
08:34jab solutions ki baat aati hai
08:36toh kitabon mein aapko aksar dekhne ko milega ki
08:38jab aap kamre mein nahi hain toh light switch off kar dijiye
08:41electricity mat waste kariye
08:43gadi ki jagah cycle ka istimaal kijiye
08:45yeh saari cheeze karni achi hain
08:47karni chahiye aapko
08:49lekin problem yeh hai ki yeh saari information
08:51outdated ho chuki hai aaj ke time pe
08:53aaj se 20 saal pehle
08:55agar sab ko yeh karne ko bola jaata
08:57aur sab ne kiya hota toh shayad kuch asar
08:59pad bhi sakta tha. Lekin aaj ke din
09:01on an individual level
09:03agar yeh chhoti chhoti cheeze se
09:05har koi karne bhi lag gaya hai saari chhoti chhoti cheeze
09:07toh bhi negligible asar padega
09:09climate change pe. Aaj ke din
09:11halat itni kharab ho chuki hai
09:13ki aap sirf government ke level pe
09:15policy changes hi real change la sakte hain
09:17duniya ko bachane ke liye
09:19kis tarahe ke policy changes ki
09:21main baat kar rahe ho? Fossil fuels per jo
09:23subsidy laga rakhi hai, unhe hatana padega
09:25saari duniya ke sarkaro ko
09:27electric cars ko push karna padega
09:29zabardas incentives dene padenge
09:31electric cars kharidne ke liye
09:33carbon tax lagana padega
09:35takhi companies apne aap motivate hoon
09:37kum fossil fuels
09:39istimaal karne ke liye
09:41aur on an individual level hume awareness
09:43raise karne padegi climate change ko lekar
09:45jisse ki sarkar ki public policy me
09:47asar pad sakhe. MIT ke researchers
09:49ne ek yeh bada interesting simulator
09:51banaya tha yeh batane ke liye ki
09:532100 tak
09:55kitna zyada global average temperature
09:57rise karega aur wo temperature
09:59kaise upar niche hoga agar hum
10:01alag-alag policy changes laenge
10:03duniya bhar ke deshon
10:05agar aap renewal energy
10:07isko bahot zyada incentivize karoge
10:09ya phir taxes badha doge
10:11fossil fuels par to usse kya change aayega
10:13iss simulator me aap yeh karke dekh sakte hain
10:15iska link mein nishe description me daal dunga
10:17bada yeh interesting hai karna
10:19iss se conclusion yeh nikalta hai ki sabse bada
10:21impact padta hai actually me carbon taxes se
10:23carbon price se
10:25aap indicator ko hila kar dekhe
10:27carbon price ka aur usse kitna bada
10:29asar aa raha hai climate change me
10:31carbon tax ka matlab hai ki humare jitne bhi
10:33alag-alag energy sources me jitna bhi
10:35carbon maujood hai proportionally
10:37unpar utna hi tax laga jaye
10:39jani jisme zyada carbon maujood
10:41hai usse zyada carbon dioxide niklegi
10:43jisse zyada climate change hoga
10:45to usse utna hi zyada tax laga jaye
10:47coal sabse zyada polluting hai
10:49to coal par sabse zyada carbon tax hoga
10:51uske baad petroleum products hai thode se kam polluting hai usse
10:53uske baad natural gas hai
10:55jisme itna zyada carbon nahi hai
10:57to usse aur kam tax hoga
10:59aur phir renewable energy hai jispe koi bhi
11:01carbon nahi maujood hai
11:03to waha par zero tax lagega
11:05aur ye tax lagaya kis par jayega
11:07achi cheez ye hai carbon tax ke baare me
11:09ki jitne bhi experts isse propose karte hain
11:11wo kehte hain ki is tax ko
11:13at the source hi lagana chahiye
11:15jani wo companies jo coal mining karne lag rahi hain
11:17ya phir wo companies jo
11:19oil ko extract karne lag rahi hain
11:21unpar tax lagaya jayega
11:23agar oil ko ya coal ko import kiya jara hai
11:25desh me kahin aur se
11:27to jo companies oil ya coal ko import
11:29karne lag rahi hain unpar tax lagaya jayega
11:31aam janta par iska asar nahi
11:33padega itna kyunki companies
11:35iska load seh rahi hain
11:37agar wo companies renewable energy se compete nahi
11:39kar paayenge price ke maamle me to aam janta
11:41obviously renewable energy ke paas
11:43jayegi aur jab ye tax
11:45companies par lagega to wo khud se motivate
11:47hoengi apni balance sheet me dekhengi ki
11:49hamare liye ab coal mining karna
11:51economically feasible nahi bacha
11:53to isliye hum isse bandh kar dete hain coal mine ko
11:55aur renewable energy me shift kar jate hain
11:57to overall duniya bhar ke scientists
11:59aur experts ka maanna hai ki ye
12:01sabse effective policy change hai
12:03jisse sabse bada impact padega
12:05climate change against fight me
12:07duniya bhar ki kai countries already
12:09carbon tax ko introduce kar chuki hain
12:11jaise ki canada jahan par
12:1320$ per ton of CO2 emissions
12:15ka charge lagaya jata hai
12:17tax lagaya jata hai umeet karta hu
12:19india jaisi countries me bhi isse introduce
12:21kiya jayega aur jab janta pressure banayegi
12:23aise policy changes par tabhi
12:25govt bhi kuch action legi
12:27aaj ke din shayad se sabse impactful
12:29tariqa hai climate change ko control me lane ka
12:31nahi to future me hume
12:3350 plus degrees ke temperature
12:35shayad india me bhi dekhne ko mile
12:37milte hain phir agle video me
12:39bahot bahot dhanyavad
