0:00:00.000,0:00:03.020
I'm professor Hans Rosling.

0:00:03.020,0:00:04.719
I hear some people say

0:00:04.719,0:00:07.360
that global warming has stopped.

0:00:07.360,0:00:11.560
They claim that temperature[br]has reached the plateau.

0:00:11.560,0:00:16.399
So I regularly check[br]at the website of NOAA,

0:00:16.399,0:00:21.519
National Oceanic and Atmospheric[br]Administration in US.

0:00:21.519,0:00:24.120
Now these are the latest data,

0:00:24.120,0:00:25.519
and I'm going to show you.

0:00:25.519,0:00:28.839
The graph shows 12-months periods,

0:00:28.839,0:00:31.519
from the year I was born, 1948,

0:00:31.519,0:00:35.000
up and including August 2014,

0:00:35.000,0:00:36.700
the latest data.

0:00:36.700,0:00:41.200
And upwards is warmer periods,

0:00:41.200,0:00:43.679
and downwards is cooler periods.

0:00:43.679,0:00:46.719
And during my first 20 years of life,

0:00:46.719,0:00:48.200
there were some warm periods,

0:00:48.200,0:00:49.119
some cold,

0:00:49.119,0:00:50.439
but since mid seventies,

0:00:50.439,0:00:52.240
when I graduated from University,

0:00:52.240,0:00:54.159
it has been going up like this!

0:00:54.159,0:00:56.799
Ok, in the last years, here,

0:00:56.799,0:00:59.399
there has been the tendence[br]of a plateau.

0:00:59.399,0:01:01.159
But let me show you now

0:01:01.159,0:01:04.339
the very last 12 month period.[br]Here we go.

0:01:04.339,0:01:08.799
These are the data up[br]to including August 2014.

0:01:08.799,0:01:13.000
It's the highest 12 months[br]period ever recorded!

0:01:13.000,0:01:15.439
And to assess this,

0:01:15.439,0:01:16.879
you have to draw a trendline,

0:01:16.879,0:01:18.640
because weather change[br]year from year;

0:01:18.640,0:01:21.000
climate change,[br]decade from decade.

0:01:21.000,0:01:21.719
Here we go,

0:01:21.719,0:01:24.000
this is the statistical trendline.

0:01:24.000,0:01:25.159
and it goes up like this,

0:01:25.159,0:01:27.319
and it makes sense when you look at it.

0:01:27.319,0:01:32.840
The last 12 months data[br]confirm the long term trend:

0:01:32.840,0:01:35.319
the temperature, on this planet,

0:01:35.319,0:01:38.000
is getting higher and higher.
