How does NASA combat climate change? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer questions about renewable energy, geoengineering, and how science is helping us battle the climate crisis with NASA Chief Scientist and Senior Climate Advisor, Katherine Calvin.
What are NASA’s plans to combat climate change? Build huge air filtration towers? What about stratospheric aerosol injections? We discuss climate modeling, the impacts of trees, and the different effects of emission scenarios. Are we approaching “the point of no return”? What is it? We break down what effects of climate change are reversible and what might be nearly impossible to fix.
We explore what keeps nuclear energy from going mainstream. Is nuclear the best scalable option? Discover the potential effects of terraforming Earth and how modeling helps us predict what will happen. Is it possible to have control of an entire planet? How do we save the trees and land ice? What can be attributed to Earth’s natural warming?
Kate directs us to climate.nasa.gov where we can stay updated on NASA’s climate activities and track up-to-date climate change information from their satellites. How will NISAR be different from other Earth-observing satellites? What would the future look like if we stopped burning fossil fuels now? Plus, we also learn a little bit about the role of being NASA’s Chief Scientist and what the position entails.
Thanks to our Patrons Marco Currin, Tyler Pitts, Jeffrey Bradley, Matthew Gottschalk, Austin Munson, Gabriela Dijkhoffz, David M, Sandra Pagliani, Brian Lacey, and Nalani Ritchie for supporting us this week.

...the thought of climate change killing off the planet is there of course, but on the other hand, I'm kinda curious about what types of evolutionary type changes climate change may bring about, I always used to joke, saying, if the dinosaur would have stopped climate change, there would be no humans today...😂😂😂🤣

@LK-pc4sq 2 года назад

I have spent hundreds of hours researching Anthropocene Climate Change. Climate Change is really serious. As long as Arctic Amplification continues to occur, there will be no going back to what was once, a 100% habitable planet. Most of the serious impacts of Climate Change are occurring between the 36th parallel and the equator. Depending on which side of the Pacific Ocean and Indian Ocean and which cycle "La nina or El Ninio or Indian Ocean Dipole, there is a good chance the populations on either side of those oceans are seeing increasing record flooding or increasing record drought that is killing wild life. Eventually large amounts of the global population with migrate into the northern latitudes of 49th parallel and into the Arctic like what occurred 52 million years ago when co2 levels were so high, that the Arctic turned Tropical. The extend of the surface area extended down to the 49th parallel. Example, in Bellingham there is the Chuckenut formation. In between sandwich layers of petrified sandstone is tropical Palm Fronds. Also tracks of Alligators were left behind.

@patrickmuller3248 2 года назад

@Shon Mardani Yes! There is basically no natural climate change occurring right now. If anything the climate should actually cool. I am heavily shortening 70 years of research. But it comes down to multiple fields we checked. So, we can measure how much energy the sun provides with satellites in orbit. They show, the same amount of energy comes from the sun as always. But, the planet absorbs more than before. There is only one explanation for more absorption: more greenhouse gases. Due to the rate of warming you can calculate how much more greenhouse gas there should be in order to account for the effect. It's quite a lot. And there are a bunch of greenhouse gas emitters out there: The ocean, animals, volcanoes, humans, etc. Turns out all the additional gas comes from humans. You can even measure specifically where the extra CO2 comes from by measuring the ratio of carbon isotopes. Turns out almost all of it is ancient carbon. Millions of years old. Plus some methane. The only thing I wonder is: Are you actually wondering if we know or is it a question from a science denier who claims this is all a lie?

@@clintonhart2652 well, it's really quite simple. Every one of them, every piece of them, every bolt or washer any astronaut has ever dropped, in fact, is recorded, tracked, and taken into consideration when they plan launches. It's not that complicated. Imagine it like a game of Frogger, for example, played by a very, very good player. They _know how_ to dodge the dangers. Why this is so complex to you, I have no idea. The concept of a wall of bits & pieces around the planet so dense that we can't safely launch anything is a real one. It's one that we could definitely have to worry about in the future, if we don't come up with a solution fairly soon. But it's _not_ the impenetrable screen you seem to try to be making it out to be, right now. So, perhaps, you know, try [try, mind you!] to use a better complaint against the globe model than this, because this fails, badly, from any angle you look at it. 😄😄😄😄 Then again, there _aren't_ any complaints against the heliocentric globe model that hold any weight whatsoever. You guys have failed, over and over again, to even comprehend non-Euclidean geometry, maths above the grade school level, or even 3D thinking. You failed the sextant challenge (or refused to take it, as you knew it would destroy you) even after claiming the sextant could only work on a flat "planet," because - surprise, surprise - it's designed specifically to work on a globe. Your comprehension of the way the globe model even works is pathetic, at best, in fact, so there's no wonder you guys fail over, and over, and over again. The real surprise is why, after being corrected over, and over, and over again, you guys continue to make the very same debunked arguments, at all. It's as bad as K. Hovind getting the basics of geology (or any other -ology, for that matter) wrong even after being proven wrong multiple times a year (often multiple times per debate, in fact). How you folks aren't too totally embarrassed to even show your virtual faces online after so many total failures is the real mystery, here. 😄😆😂🤣😂😆😄

@TheLosamatic 2 года назад

But something like an iceberg is not cold it just has an absence of heat, right? If so it melting does not give you warmth or energy ? Ok now my head hurts!

@robcarson2728 2 года назад

@@TheLosamatic that's a great question, and one I wish more people would ask! Melting an iceberg takes away energy (heat) from it's surroundings, because you have changed its state to a higher energy one (liquid water)... This is why ice cubes make your drinks colder, heat energy from the drink was spent changing the solid water into higher energy liquid water. It's true to say that the iceberg has an "absence of heat" but only compared with things that are warmer than it. The ice still has energy (heat), that is true for any substance above absolute zero. The water molecules in the ice are still vibrating away. And if you give them enough energy to escape the solid state, the ice melts. So, if you were to somehow take a big pile of ocean water and make it into an iceberg or glacier, you would have extracted all of the energy that it had to be a liquid... Also if that glacier pushed up onto land somewhere, the sea level would go down (win win)!

Ms. Calvin, I never got a straight answer on one key question. How much uncertainty is on each variable of the climate models, and how much error propagation (both from the model and from computation) is accumulated on short, mid and long term scenarios. From a statistics perspective, we really should have clarity on this in order to properly understand the confidence of any prediction from the models.

@craigscott2315 2 года назад

the models have a margin of error that significantly exceeds 2 deg C, for both cooling and warming. In silica nonsense! in particularly regard to carbon dioxide hardly even a trace atmospheric gas... 380 parts carbon dioxide per one million parts water vapour (primary green house gas)! Add to that 18th c. discovery of hydrogen, oxygen and carbon dioxide using a lit taper as prof of gas presence, carbon dioxide doesn't have the mass for the troposphere to support it in the atmosphere. Global warming was debunked in 1886! Three percent into a cooling phase! And east antarctic has been growing. Glaciers travel at a measurable rate. Hubbard glacier creates an ice lake every 20-40 years moving from peak to sea in 400 years. The heavier a glacier is the faster it moves!

@ziguirayou 2 года назад

@@MattIsntYoung I understand your point. I did my masters in simulation. Computing error propagation (rounding due to memory constraints on each and every variable) alone can completely break a sim. Add that to all simplification that goes into a model (you can't simulate every particle and every interaction), and you're facing a true nightmare a few million interactions down the road. That being said, simulations are a VERY useful tool, but we must understand it's limitations. All I'm concerned about is that at the scale of a simulated global climate model, uncertainty could potentially be too large to draw meaningful conclusions.

The public issue with nuclear power hinges around politicians looking for a short term solution. A nuclear power plant takes longer to build and costs more money than a coal plant. A politician has to convince people to use that money for a result that will be in the next election cycle.

Germany switching from nuclear to coal and gas because of Fukushima was political and a damn shame.

How difficult would it be to put the patron’s name on the screen when asking their question? I enjoy Chuck’s name-butchering, but this way, at least the patron can actually be recognized.

I totally agree with this episode. However pollution of land, sea and air needs to be the focal point. If only we can find environmentally friendly ways to address our daily activities.

:Politicians: we are at the point of no return. :Cambrian explosion: lol. NASA still not looking back that far in geologic history eh? Also for the majority of time life has existed on Earth- there was no ice sheets. What we have here is normalcy bias. We should be focused on preparing for more climate change, not averting it- it's inefficient and it's also pie in the sky wishing that the rest of the world will do their part. It might happen, but why take the risk.

There are many problems with nuclear fission. First of all global, uranium deposits are limited. If you wanted to meet global energy demand with only nuclear fission, global supply would run out in less then 30 years. Also most deposits are in remote areas like the himalayas, the andes ... and russia. Secondly, nuclear energy is actually the most expensive form of electricity generation, if you factor in uranium-mining and storage of nuclear waste, which is both tax-financed by all nations who run nuclear reactors. The cheapest form of energy is actually solar, then wind. Their only problem is, that they can function decentralized, so big corporations would lose their monopolies. Lastly, building new reactors are huge products, which take 15-20 years from planning to building. Which is just too slow to meat the Paris goals.

12:18 Can not use any ice machine without generating heat. Much more heat than the created ice can remove by the way. After all, that is why refrigerators are not vented internally. It is why a window air conditioner is vented outside and not inside. Compressing a refrigerant generates a LOT of heat.

So the colour white doesn't absorb heat, it reflects it (away). I have always wondered if painting all the roofs of buildings white and keeping them white would have any cooling effect, and if so, how much? 🤔

@Pallavme 2 года назад

Having watched hundreds of StarTalk videos, this must be the WORST video ever. The guest hardly provided any answer at all. Reminded me about how I would just keep writing words and sentences in exams when I had no clue what to write. Please never ever get her back and that's someone from NASA, uugghhh. Thank You Chuck for still making it so much enjoyable.

@rolando2395 2 года назад

So this is my question... I don't know if maybe I heard it somewhere and not remember and now I think this is my idea... But... Can we install something in busy highways that would create electricity by friction from the weels on the roads??

@TheCam4 2 года назад

Never heard of this one... Cars do have rechargable batteries that get charged using a dynamo attached to the engine. That battery runs a car's electrics. However, large scale production of electricity would not be feasible using just friction. Basically, electricity is produced by heat. Heat turns water into steam that truns turbines attached to generators producing electricity. Here's a turn on the idea, if we move a conductor through a magnetic field it should produce electricity. The cars are already conductors (made of iron), all we have to do is install giant magnets by the road...
