1
00:04:01,639 --> 00:04:10,019
higher levels of CO2. It turns out that carbon
dioxide are not "dirty" words after all.

2
00:03:48,120 --> 00:03:55,199
In fact, we're already seeing the positive
effects of increased carbon dioxide now. Satellite

3
00:03:42,629 --> 00:03:48,120
since by mid-century we will have to feed
8-10 billion people.

4
00:03:55,199 --> 00:04:01,639
measurements have noted the "greening of the
earth" as crops and forests grow due to our

5
00:03:35,779 --> 00:03:42,629
in the global atmosphere will boost food and
forest productivity. That will come in handy

6
00:03:29,129 --> 00:03:35,779
into their greenhouses -- they want to promote
plant growth. Likewise, higher CO2 levels

7
00:03:14,930 --> 00:03:21,980
The optimum level of CO2 for plant growth, for example, is four to five times what is currently found

8
00:03:21,989 --> 00:03:29,129
in our atmosphere. That's why greenhouse growers
worldwide actually inject additional CO2

9
00:03:00,370 --> 00:03:08,290
life first came on the scene, CO2 levels were
as much as 10 times higher than they are today.

10
00:03:08,290 --> 00:03:14,930
From a big picture perspective, we're actually
living in a low carbon dioxide era.

11
00:02:53,629 --> 00:03:00,370
at much higher levels than it is today. During
the Cambrian explosion, when multi-cellular

12
00:02:47,520 --> 00:02:53,620
For most of the history of life on earth carbon
dioxide has been present in the atmosphere

13
00:02:44,939 --> 00:02:47,499
we find something surprising.

14
00:02:38,780 --> 00:02:44,939
-- CO2 levels are getting too high. Are they
right? Well, if we look at the big picture

15
00:02:32,089 --> 00:02:38,780
Can you have too much of it? In theory, yes. That's
what climate alarmists say is happening now

16
00:02:24,829 --> 00:02:32,089
odorless, tasteless gas which is an indispensable
food for all living things.

17
00:02:16,680 --> 00:02:24,820
That is entirely misleading. Carbon dioxide is
not carbon. Carbon dioxide is a colorless,

18
00:02:10,500 --> 00:02:16,680
to refer to the emissions from burning fossil
fuels for energy as "carbon" emissions.

19
00:02:03,820 --> 00:02:10,500
Before I deal with that question, let's get
clear on our terms. It has become common

20
00:01:58,920 --> 00:02:03,820
But, how can something that makes
life possible be bad?

21
00:01:50,460 --> 00:01:58,920
And yet, the US Environmental Protection Agency has
deemed this essential ingredient for life a pollutant!

22
00:01:37,820 --> 00:01:45,240
If there were no carbon dioxide in the Earth's
atmosphere, the Earth would be a dead planet. Period.

23
00:01:45,240 --> 00:01:50,460
Talk about catastrophic climate change.
Take away CO2 and you'd have it.

24
00:01:31,060 --> 00:01:37,820
organic and were produced with solar energy.
Sounds positively green.

25
00:01:26,210 --> 00:01:31,060
Earth's crust. In other words, fossil fuels are 100 percent

26
00:01:20,540 --> 00:01:26,210
of those plankton and plants that have been
transformed by heat and pressure deep in the

27
00:01:00,190 --> 00:01:06,490
from carbon dioxide in the atmosphere. All
of the carbon in the fossil fuels we are burning

28
00:01:13,280 --> 00:01:20,540
plankton in the sea and plants on the land.
Coal, oil, and natural gas are the remains

29
00:01:06,490 --> 00:01:13,280
for energy today was once in the atmosphere
as carbon dioxide before it was consumed by

30
00:00:52,380 --> 00:01:00,180
Here's what strange, though. All life is carbon-based,
and the carbon for all that life originates

31
00:00:37,160 --> 00:00:46,940
fossil fuels, which constitute 85% of our
energy use must be reduced to zero by 2100.

32
00:00:31,020 --> 00:00:37,100
According to the Intergovernmental Panel on
Climate Change, the IPCC, CO2 emissions from

33
00:00:46,950 --> 00:00:52,310
If we don't save ourselves from ourselves,
we're toast. That's the claim.

34
00:00:26,060 --> 00:00:30,980
the argument goes, we're going to alter the climate. Catastrophically.

35
00:00:19,600 --> 00:00:26,040
One atom of carbon and two atoms of oxygen. If we pump much more of it into the atmosphere,

36
00:00:11,260 --> 00:00:19,600
The two words are "Carbon Dioxide." Or as it is known by its chemical symbol -- CO2.

37
00:04:10,080 --> 00:04:15,180
We should celebrate CO2 as the giver of life that it is.

38
00:04:15,180 --> 00:04:19,900
I'm Patrick Moore, co-founder of Greenpeace for Prager University.

39
00:00:06,050 --> 00:00:11,210
with Global Warming as so many people are
these days, the answer is obvious.

40
00:00:01,400 --> 00:00:05,980
What are two of the dirtiest words in the
English language? Well, if you're concerned
