00:00Warming cycles are natural. If we go back into the different interglacial periods, we see that climate has always fluctuated.
00:09So it's nothing really new. In fact, if you look at temperature across 500 million years, we're actually at slightly
00:17lower temperatures. So what's the big fuss about?
00:20In the industrial age, in the last 100-150 years, which is a very small period, the CO2 PPM has
00:29gone up from 280 to around 440 now. 150 years is nothing. Because in the past, whenever temperature rose or
00:39fell, it didn't happen in 100 or 200 years. It happened over lakhs of years.
00:44When it happens over that kind of time period, then the life forms have enough time to acclimatize. Right? And
00:56even if it's being felt by human populations, in the current Holocene, also it has happened around 4-5 thousand
01:06years before Christ, which is like 6 thousand years from today.
01:11When it happened, the human populations were smaller. So they could easily migrate. And even then, when migration was happening,
01:20it was not harmless. The Indus Valley civilization itself is thought to have come to an end because of reasons
01:30related to climate change.
01:32Shifting monsool patterns. Shifting monsool patterns. The Sahara desert of today was a lively green place. And then it stopped
01:40raining. The climate changed. And now you have nothing but sand there. Are you kidding me?
01:46Then nobody got killed. Because nobody was there to live. Today, think, if the Indo-Gangetic plane turns into a
01:58Sahara, what are the consequences?
