Predicting Earth’s Climate Future with Neil deGrasse Tyson & Kate Marvel, PhD - Cosmic Queries

What can the climate on Venus tell us about Earth? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer questions about climate modeling, the state of climate change, and future predictions with climate scientist, Kate Marvel.
What if the Earth had no Rocky Mountains? Learn about climate modeling and what it’s like to play Sims with physics on a supercomputer. If Thanos’s plan worked, would that put a stop to climate change? Find out why the human population isn’t the problem and when we will see the benefits of various green initiatives. What if humans were half the size we are? What is the difference between weather and climate?
What changes that we’ve caused to our climate are actually reversible? How many more droughts will we be seeing and where? Learn about places where rainfall will increase and where it will decrease. Are models good enough to replace empirical experimentation? We discuss climate research on the moon, Mars, and Venus. What are the top five most important climate solutions?
Discover creating worlds in a supercomputer, Newton’s laws of motion, and climate modeling organizations around the world. We take a look at systemic changes that are helping the cause and how to get people in power to care about climate change. How can we communicate urgency without people giving up hope?

What's Your Climate Solution?

[@upmanyubhati]

Everyone do their best to help the plant.

[@michaelccopelandsr7120]

I've figured out how to fix this but no one believes me. Maybe it's because 1 of the 7 things I want in return is to change the stars. My idea for changing the stars includes Orion and Pleiades (Subaru). I figure it's time to put something up there that's relevant to us, don't you think? Take Orion's belt and Betelgeuse becomes the head with a baseball hat. The 3 stars of Orion's belt make up the 3 fat belt loops on a baseball uniform. Below the belt are two legs bending at the knee. Saiph is the back foot and Rigel is the front foot. The spear pointing at "Subaru" is the bat being swung and "Pleiades" is the baseball flying away after being hit. Bellatrix is the hand that let go of the bat. Put it all together and you get, "THE ALL-STAR." In my case, I see a left-handed batter and I imagine a "7" on the jersey. Which makes him, "Mickey." (As it should be ;-) But you can put any number you want, making, "THE ALL-STAR," any player you want. It'd be wrong of me to not, at least, try. This is me, trying. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment. ;-P

[@licentiaplaythrough7663]

People talk about solar and wind as the answer....... but never talk about the cost of making these sources. the cobalt and and nickel needed for example. the methods used to mine it all and the impacts it creates...... then your looking at the waste, when solar panels and turbine blades reach their end of life, what do we do with all of this in 30 years and the toxic components....??????? For me to your answer and that is nuclear power plants.. If you look up deaths per KW from each source of power we use today, nuclear seems to be the way to go. Then we can focus on waste management with the nuclear rods. even invest in rocket technology for shooting the rods in to space and out of the solar system.

Glad Chuck mentioned the freeze. I'm in Eastern Washington and that's what is happening. It's a heavy growing area with wheat, apples and more. The area has always relied on the snowpack through a good portion of the season. Now both less snow is falling and the snow that there is melts faster because of warmer air. We have drought and crops are down.

I'm going to mention and recommend, (because I know Dr. Tyson can't promote it himself), people watch (and recommend to OTHER people to watch) the 12th episode of Cosmos: A Spacetime Odyssey, (hosted by Dr. Tyson), entitled "The World Set Free".

I’ve been saying when we shutdown two years ago with no vehicles on the road the air seemed so much better. No noise pollution very low carbon in the air breathing was so much better. We’ve pretty much done the experiment if we paid attention in 2020. Though that type experiment was one I’d have rather not have had due to the circumstances at which we had to shut down. Essentially we know what reducing pollution will do for us. Too many people with power just don’t care.

[@ryanw8987]

Unfortunately, too many people have the false belief that automobiles=strong economy, and for them economy is top priority. For commercial vehicles, sure, but technology can change the amount of impact on that front. But for personal mobility, current car culture is a net negative on the economy. The problem is that so much of the costs are absorbed in externalities that it makes it too complex for a lot of people to understand, or really even try to understand, and it makes it easy for those who profit from car usage to claim that something else is to blame.

[@longbranch5921]

I never stop driving. Sometimes i just start my gasoline car and just let it idle

[@SparkyWrench]

I don't think it's necessarily about people with power not caring so much as it is about the general population enjoying their ability to go and do what they want when they want. It's our own selfishness, especially when short-term it is economically easier for all of us. Essentially we don't have the "pain" needed for significant change and those in power don't have the incentive.

I love seeing these connections as they allow me to learn of new communicators to broaden my field of view, and I look forward to more! Sincerely, Zeus

[@ElementalAngelKashi]

the main reason why thanos never considered increasing the resources was that people would not change their ways just because things became plentiful. a good example of this was when we sent food to Africa and it was to be distributed but the local warlords took control of those supplies and sold them to fund their own livelihoods. however like you saw in the marvel movies when half the people were gone they had to change as the structures that relied on the numbers suddenly could no longer sustain itself. to be honest cosmic power at your fingers why not make everyone smarter and more cooperating.

[@fumakage1654]

I’ve been working in Germany and have been put into positions that really made the inner workings of companies (global players) transparent. My last job with one of the worlds largest injection moulding machine companies (machine for mass production of plastic parts - from cups to car parts) letting me see how many of these huge production machines get sold and shipped worldwide on a daily basis (especially with that output of machines and the machines output itself!) was another cause for me to further doubt any possible positive progress on an environmental level. Germany is known as one of the “greener” countries which really made me think about whats going on worldwide. I really hope we all can get away from this material and start treating our environment and each other with much more respect. We need many more very active people with this “Startalk/environmentally friendly - mindset” in politics and at the head of companies worldwide FAST but I don’t think it is at all possible unless we change this political/capitalism setup. I think we finally need to optimise effectivity towards the/an environmental department (that NO ONE has a backdoor to - no matter how big the company or money behind them) MUCH more and put a stop to “greenwashing” in a way that ACTUALLY works and best on a global scale.

That's all houses, garages, barns, warehouses, everything that has a roof is a power generator.

Something that I do believe that contributes, greatly, to the climate issue are the roads covered by asphalt.

So it's not just fuels.

There are so many factors that have to do with the weather and the climate. Such as why we have a thousand tornadoes a year in the United States. Like the fact that there are no mountain ranges that run east and west. Combine the arctic and gulf of Mexico with the mountain ranges. Warm moist air from the gulf of Mexico and cold air from the arctic. You have unstable weather and possible tornadoes. Those same factors play their part in climate as well.

Deborah from Finland, If your family does not understand average temperature trends and statistics on melting glaciers, and CO2 trapping heat in the air, then they are apparently determined not to understand. The predictions of climatologists were understated. It is worse than most thought (or as bad, but sooner than most thought) I suggest appealing to the best in them: Do they want to be good stewards of the Earth? Maybe they don’t . Maybe they believe that the Bible tells them that God gave them free reign to abuse the environment (even tho they’re saying the environment is fine.) Do they want a healthy environment for their descendants? That may be the issue to focus on, because we generally model our beliefs on who we want to be.

An honest question here, since I don’t know the answer. We have water filtering systems that can literally transform raw sewage into drinkable water. Why have we not found a feasible method to remove salt from seawater, and transform it to potable, even drinkable water? It may not make a difference in the sea levels, but with so many droughts in the world, it seems like a good idea to pipeline water into drought-stricken areas, irrigate crops and farmland, even create fertile areas in the world that have always have had drought and famine! ???

A major issue of desalination is the co-produced waste called ‘brine’ or ‘reject’ which has a high salinity along with chemical residuals and is discharged into the marine environment. In addition to brine, other main issues are the high energy consumption of the desalination and brine treatment technologies.

[@jenynce]

Hie Neil I have a question ? I have watched a lot about how clumps of rocks started merging to form earth theory but if that’s the case where did the core of earth come from ? Does this mean it was actually the core that started attracting rocks to form earth ? Where does the rock even come from as I understand supernova happens and sun explodes nebula full of dust and cloud they then merges to make brand new sun so where did the rock come from ? Also all 8 planets did they all have core like earth if so why Jupiter wasn’t made by rocks ?

[@JustSomeCanuck]

The core of the Earth would only have formed after the planet reached a certain size. One of the criteria used in the current definition of a planet is that it reaches hydrostatic equilibrium - basically, that it is large and heavy enough for its own gravity to make it round. The core is made of whatever is in the middle when this occurs, plus the heavier components of the rest of the planet. The heavy stuff will gradually sink to the core over time. The rocks are formed as small pieces of cosmic dust left over from a dying star gradually collect by gravity and electromagnetic attraction. Jupiter and Saturn do have rocky or metallic cores, but they grew big enough early enough to also attract gases in the Solar System before the Sun's solar wind pushed all of the gases away.

Collectivism rules, we are a social species, these are problems caused by our social interactions especially exploitative ones. We are individuals but some take that to the nth degree which speaks to our most base, selfish instincts. We must come together🎶

I am battling climate issues by stopping driving my v6 Toyota truck 95% of the time and riding my e-bike. the cost savings is already very noticeable. costs 10 cents a day to charge the bike verses 5 bucks a gallon for my Toyota.

How do you secure it when leaving it parked.

So basically, another way to describe tipping points is like smoking. You know it's bad and there will be various stages of sickness that is likely hard to correct or irreversible. First you might start getting shortness of breath and a chronic cough. The doctor tells you what is causing it and you know why this is happening so you try to reverse the symptoms, but if you don't stop smoking, you are really not making any progress. Eventually, if you continue smoking, it could get so bad that not only will your life expectancy be drastically reduced, but you could develop cancer. In other words, it becomes so irreversible, it becomes a sudden death sentence. Could be a bad analogy but it makes sense in my head.

My question about cutting out meat is this. Since 98% of chickens, pigs, cows etc are only bred on farms by farmers for consumption, wouldn't it eliminate the entire 98% of them by not giving the farmer a reason to actually have them or breed them?

[@lemongavine]

Your question makes a good point. Would those animals go extinct?

I don't have the knowledge necessary to understand what reducing salt content of the ocean will have but do know that salt water does not become ice.

The April snow thing to me is climate change because we said April showers bring May flowers as a kid, but nowadays we have snow and blizzards in April and rain for a decent chunk of May. It's like the climate change has literally shifted the seasons by a month. Watch the weather this December, you'll see what I mean.

We don't need to stop eating meat! We need to change how we farm. The great plains were fertile because of the buffalo. Having free range animals fertilize the landscape, captures water and allows for the diversity of plants. Plants eat carbon! So maybe instead of trying to keep the buffalo population down to a few thousand animals. Maybe we should be repopulating the great plains. .... Just sayin

[@Vaeldarg]

How much demand is there for buffalo meat instead of cow meat?

[@Viper_Poker]

@@Vaeldarg you kinda missed the point. Healthy plant life not only eats carbon they also create rain, trap water and help raise the water table. Instead of slaughtering 1800 to 2000 animals a year. Maybe we auta be using them to help fertilize the great plains and the pan handle again. ... Just sayin

[@pisztufilm]

@@Vaeldarg cows do the job very well too.

Get your big on for the climate change fight!

She is right Noone wants to hear the science or look at a graph. You have to convince most people that it is cool and fancy to use clean energy. People don't drive tesla to save the earth. It is a status symbol and the car looks nice and says you have money.

When considering emissions in discourse with deniers, point out the global impact removing lead from gasoline had - now that they have an idea, apply it to emissions in general and ask what they'd rather have us be dumping in our air

[@themr_wilson]

Cruise liners are among the worst offenders of CO2 emissions
