00:00More and more sun. More and more heat.
00:03Climate change is endangering the health of hundreds of thousands.
00:07It will also mean less income.
00:09By mid-century, we will earn significantly less than we would without the climate crisis.
00:15How high will the cost be?
00:17So up until about 2050,
00:19we see that the world economy is going to be projected to a decline in income of 19%.
00:25Take India, for example.
00:27Economically, it stands to lose with climate change.
00:30Heat and drought are damaging agriculture.
00:33And who will bring in the harvest when temperatures are so hot?
00:38It's 40 degrees Celsius right now at 5 pm in Delhi.
00:434-0 degrees Celsius, yes.
00:45At least during peak hours of, say, 11 to 4,
00:49it's really not possible to work outdoors.
00:54Heat and drought.
00:56These consequences of climate change also threaten many African countries.
01:00The economic impact is enormous.
01:03Labour productivity and crop productivity,
01:07these show clear responses to temperatures,
01:10where in particular their productivity declines at high temperatures around 20 to 30 degrees.
01:15And of course, global warming is causing the greatest damage where it's already hot today.
01:21In the middle of the century,
01:22the regions south of the equator will generate significantly less income
01:27than they would have without the climate crisis.
01:30Which brings us back to India.
01:32The population there will lose 22% of its 2050 income by the middle of the century,
01:39although a few will benefit.
01:42Manufacturers of air conditioning systems are experiencing a boom,
01:46with major social consequences, however.
01:52Because as it gets hotter, the need for air conditioning multiplies,
01:56and more and more households can afford them.
01:59The problem? The high power consumption.
02:03With the increasing heat,
02:05of course the power sector needs to prepare itself for an excessive demand in coming years,
02:11and the infrastructure needs to be built on those lines.
02:14So far, however, most electricity in India has been generated from coal.
02:19Its enormous emissions are again driving global warming.
02:23It's a vicious circle.
02:25What to do? Many are pinning their hopes on technical progress.
02:30Of course, we will need energy efficient air conditioners
02:34to reduce the energy demand for this,
02:37which can really peak to multi-fold demand
02:40compared to the current energy demand in India.
02:47India has adopted a national action plan.
02:50Among other things, buildings are to be modified so that they heat up less quickly,
02:55and new buildings should be oriented according to old models.
02:59India also wants to expand renewable energies.
03:03However, this is happening far too slowly,
03:05a problem for the whole world and the next generation,
03:09because the climate crisis will not be ending in the middle of the century.
03:13Quite the opposite.
03:17A Paris-compatible world, let's say, has much smaller damages on the range of 20%,
03:22whereas a high-warming scenario has much larger damages on the range of 50%.
03:28If you weren't convinced before, climate researchers can now prove it.
03:32The switch to a CO2-neutral economy is expensive,
03:36but it's worth it to avoid even greater losses of income.
