00:00The Eemian interglacial period, during that, the temperature rise was about 3 to 6 degrees.
00:05There were no humans then and temperature increased.
00:08So temperature can increase without humans being there.
00:11So how do we know that the temperature increase right now is by humans?
00:15Such a bad argument. A school kid knows how to answer this.
00:18Why are you unnecessarily blaming us?
00:19We are little cute, innocent babies.
00:21We are doing nothing, just playing around something.
00:23Needlessly telling us that we are destroying the earth.
00:25We are not doing anything.
00:26We know the CO2 level has risen from 280 parts per million to 432.
00:32The carbon in the air, in the atmosphere, comes in three isotopes.
00:36C12, C13, C14.
00:38And they occur in a particular ratio.
00:40Fossil fuels emit C12.
00:43And compared to pre-industrial levels, C12 has risen in proportion so much that C13 and C14,
00:52their proportions have been reduced.
00:56So this is clear evidence that the excess carbon dioxide is coming from fossil fuels,
01:02which is human activity.
01:04We do not just know that there is excess carbon.
01:08We also have proof that that excess carbon is coming from coal, from gas, from such things.
01:15Because it is these things that emit C12 isotope.
01:19So that excess carbon dioxide is coming from
01:23you so 1300 lactose sulfuric energy is building in this area.
01:24So here you see also a spine efficiency.
