1
00:00:00,000 --> 00:00:03,020
I'm professor Hans Rosling.

2
00:00:03,020 --> 00:00:04,719
I hear some people say

3
00:00:04,719 --> 00:00:07,360
that global warming has stopped.

4
00:00:07,360 --> 00:00:11,560
They claim that temperature
has reached the plateau.

5
00:00:11,560 --> 00:00:16,399
So I regularly check
at the website of NOAA,

6
00:00:16,399 --> 00:00:21,519
National Oceanic and Atmospheric
Administration in US.

7
00:00:21,519 --> 00:00:24,120
Now these are the latest data,

8
00:00:24,120 --> 00:00:25,519
and I'm going to show you.

9
00:00:25,519 --> 00:00:28,839
The graph shows 12-months periods,

10
00:00:28,839 --> 00:00:31,519
from the year I was born, 1948,

11
00:00:31,519 --> 00:00:35,000
up and including August 2014,

12
00:00:35,000 --> 00:00:36,700
the latest data.

13
00:00:36,700 --> 00:00:41,200
And upwards is warmer periods,

14
00:00:41,200 --> 00:00:43,679
and downwards is cooler periods.

15
00:00:43,679 --> 00:00:46,719
And during my first 20 years of life,

16
00:00:46,719 --> 00:00:48,200
there were some warm periods,

17
00:00:48,200 --> 00:00:49,119
some cold,

18
00:00:49,119 --> 00:00:50,439
but since mid seventies,

19
00:00:50,439 --> 00:00:52,240
when I graduated from University,

20
00:00:52,240 --> 00:00:54,159
it has been going up like this!

21
00:00:54,159 --> 00:00:56,799
Ok, in the last years, here,

22
00:00:56,799 --> 00:00:59,399
there has been the tendence
of a plateau.

23
00:00:59,399 --> 00:01:01,159
But let me show you now

24
00:01:01,159 --> 00:01:04,339
the very last 12 month period.
Here we go.

25
00:01:04,339 --> 00:01:08,799
These are the data up
to including August 2014.

26
00:01:08,799 --> 00:01:13,000
It's the highest 12 months
period ever recorded!

27
00:01:13,000 --> 00:01:15,439
And to assess this,

28
00:01:15,439 --> 00:01:16,879
you have to draw a trendline,

29
00:01:16,879 --> 00:01:18,640
because weather change
year from year;

30
00:01:18,640 --> 00:01:21,000
climate change,
decade from decade.

31
00:01:21,000 --> 00:01:21,719
Here we go,

32
00:01:21,719 --> 00:01:24,000
this is the statistical trendline.

33
00:01:24,000 --> 00:01:25,159
and it goes up like this,

34
00:01:25,159 --> 00:01:27,319
and it makes sense when you look at it.

35
00:01:27,319 --> 00:01:32,840
The last 12 months data
confirm the long term trend:

36
00:01:32,840 --> 00:01:35,319
the temperature, on this planet,

37
00:01:35,319 --> 00:01:38,000
is getting higher and higher.
