Why is 1.5 degrees such a big deal?
چرا ۱.۵ درجه انقدر مهم است؟
00:05
Because to warm our entire planet up by 1.5 degrees Celsius
چون برای اینکه دمای کل سیاره زمین را ۱.۵ درجه بالا ببریم،
00:10
requires a lot of heat.
به گرمای زیادی نیاز داریم.
00:12
All this extra heat melts glaciers, which raise sea levels.
این گرمای اضافی یخچال‌های طبیعی را آب می‌کند که سطح دریا را بالا می‌برد.
00:16
If the ice sheets of Antarctica and Greenland melt completely,
اگر قطعات یخی قطب جنوب و گرینلند بطور کامل ذوب شود،
00:19
millions of people's homes will be under water.
خانه‌های میلیون‌ها نفر به زیر آب می‌رود.
00:22
The extra heat also intensifies weather,
گرمای اضافی آب‌و هوا را بدتر می‌کند،
00:25
making wet places wetter, dry places drier
جاهای خشک را خشک‌تر و جاهای مرطوب را مرطوب‌تر می‌کند،
00:28
and increasing the ferocity of storms.
و شدت طوفان‌ها را افزایش می‌دهد.
00:30
That 1.5-degree increase also won't be distributed evenly.
افزایش یک و نیم درجه‌ای بطور یکسان در زمین پخش نخواهد شد.
00:34
The coldest nights in the Arctic might get 10 degrees warmer.
سردترین شب‌های قطب شمال ممکن است ده درجه گرمتر شود.
00:38
The warmest days in Mumbai might get five degrees hotter.
گرمترین روزهای بمبئی ممکن است پنج درجه گرمتر شود.
00:41
Over the past 10,000 years, we've been lucky.
طی ده هزار سال گذشته ما خوش‌شانس بودیم.
00:44
Earth's climate was stable and our civilizations flourished.
آب‌وهوای زمین ثبات داشت و تمدن‌ها شکوفا شدند.
00:48
But as our climate gets more unstable, so will our economies and our societies.
اما همانطور که آب‌وهوا بی‌ثبات می‌شود، اقتصاد و جوامع ما هم بی‌ثبات می‌شود.
00:53
We'll all suffer,
همه ما با هم رنج می‌بریم.
00:55
and the vulnerable will be hit hardest,
و کسانیکه ضعیف‌ترند ضربه سخت‌تری خواهند خورد،
00:57
unless we act now.
مگر اینکه امروز وارد عمل شویم.
