28:25 | Can high-tech solutions help protect the climate? What would be the side effects of further human intervention in nature?
9:56 | Solar geoengineering happens in nature when huge volcanic eruptions cover the stratosphere with ash. Solar geoengineering takes advantage of that principle, using different scientific methods to make the planet more reflective overall.
12:51 | Could it become the last option to stop global warming or is it an insane intervention? Here are three mind blowing ideas how this might work.
42:25 | Engineers and scientists are trying to intervene in the Earth’s geochemical cycles. Because it appears efforts to cut CO2 won’t suffice to avoid irreversible climate change. But does geoengineering offer a real solution? Or is it just human hubris?
28:45 | Space shades are often touted as our last hope if our climate change situation gets too out of control.
10:45 | The coronavirus brought much of the world to a standstill, dropping carbon emissions by five percent. Al Gore says keeping those rates down is now up to us.
12:44 | We look at how silver bullet geoengineering ideas can be appealing in theory, but in practice they often have a lot of ethical, economic, and social drawbacks.
42:26 | Scientists are testing new technologies they hope could counteract the effects of climate change. But how could that work on a global scale? And – if it is possible at all – what are the dangers?
14:49 | As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space.
19:06 | David Keith, Josh Horton, and Pete Irvine of Harvard University discuss the pros and cons of counter-geoengineering.
4:46 | Many view geo-engineering methods as promising business opportunities. Others see them as incalculable risks.
4:42 | What if we could reflect some of the sun’s energy away before it had a chance to get trapped?
13:34 | Geoengineering has really split the scientific community. Some believe we’ll be meddling even more with the balance of our biosphere without really understanding the consequences. Others believe we’ve got nothing to lose.
46:16 | Prof. Daniel Cziczo provides an overview of the climate change issue and then a critique of geoengineering.
12:25 | Can geoengineering help mitigate the risks of climate change? CBC’s Bob McDonald takes a closer look.
3:49 | If we overheat the planet – can’t we just cool it down again? Or can’t we just wait till it cools down by itself? And how can you look this good when you’re 62 and 3/4?!
29:11 | Professor Daniel Cziczo explains the CO2 problem and the three major types of geoengineering. We learn why the only viable approach is CO2 sequestration — pulling the CO2 out of the atmosphere.
