2 
00:00:10,100 --> 00:00:15,260 
In general, there are expected to be 
and are already observed to be, 

3 
00:00:15,260 --> 00:00:20,350 
more intense rainfall events, 

4 
00:00:20,350 --> 00:00:25,150 
more heat wave events. 

5 
00:00:25,150 --> 00:00:29,890 
A heatwave driven by greenhouse 
gases tends 

6 
00:00:29,890 --> 00:00:35,480 
to not relent at night as much a 
natural heatwave would have. 

7 
00:00:35,480 --> 00:00:37,990 
By putting more CO2 in the atmosphere, 
you're 

8 
00:00:37,990 --> 00:00:40,700 
making it hard for energy to leave the 
planet, 

9 
00:00:40,700 --> 00:00:46,870 
and so the the real killer is that at 
nighttime, it doesn't cool down and 

10 
00:00:46,870 --> 00:00:50,810 
give everybody and everything a 
chance to kind of recover in the same way. 

11 
00:00:50,810 --> 00:00:56,460 
And heat waves are potentially problematic 
for agriculture because they're 

12 
00:00:56,460 --> 00:01:02,350 
thresholds. 
About 90 degrees fahrenheit or 

13 
00:01:02,350 --> 00:01:06,290 
around there, 95 is a threshold for corn 
for example. 

14 
00:01:06,290 --> 00:01:09,890 
If you have too many days above that, 
suddenly the crop can fail. 

15 
00:01:11,212 --> 00:01:18,350 
There are different aspects of 
storminess. 

16 
00:01:18,350 --> 00:01:19,690 
There are hurricanes,

17 
00:01:19,690 --> 00:01:22,240 
thunderstorms, floods...

18 
00:01:22,240 --> 00:01:25,940 
and they're all affected by 
climate change differently. 

19 
00:01:25,940 --> 00:01:27,550 
But in general, we can summarize

20 
00:01:27,550 --> 00:01:30,560 
by saying that the severity 
of extreme 

21 
00:01:30,560 --> 00:01:33,781 
events is expected to increase in a warmer 
world.
