If anyone did not understand what this man said, then you are very dead inside.

Now I understand what greenhouse gas is how they work and what the affects are. It is mind boggling that this realm exist and how he put it into perspective.
Funny how in the name of industrialization we as man will eventually kill the unborn of tomorrow. Who are we, to say we get to live and you don't.
Off topic.
My people conquered your land. From this day forward we are superior and you are beneath us. And that folks is racism at its fullest.

That's one of the things about Carl Sagan - his ability to take complex ideas and translate them in so that almost anyone could understand them. Neil DeGrasse Tyson also has that ability.

the fact he was so clear cut on our eventual killer, greenhouse gases and their ilk, is what is both astounding and sad. Some earnest young scientists are working on a way to capture green house gases in the atmosphere, but the tech is moving slow.

Carl was a great astronomer who passed a bit early and most likely had more good work to do.
That was a very good apolitical talk he presented at a time before politicians like Gore latched onto 'climate change' as a scheme rather than being concerned about the true nature of the problem and moving towards rational solutions.
Sagan rightfully points out the need to explore alternative energy such as solar and cites fission/fusion reactors as an energy source with almost zero CO2 emissions. He rightfully points out the serious economic implications of blindly cutting back on fossil fuel production.
I liked the contrast with Earth's atmosphere with that of Venus which has an orbital distance from the sun roughly 28% less than that of Earth's orbital distance. Not much different really. But yet the temperature on Venus is 900F due in large part to the greenhouse effect. Almost seems to imply the Earth is going to turn into Venus any decade now...
OK but here's what he's not saying... The Earth currently has vast, deep oceans whereas Venus does not and only a few astronomers only speculate that Venus may have had 'some water'.
Earth's oceans do 2 things...
1) Acts as a thermal buffer to keep the ocean temperature well regulated compared to land.
2) Along with plant life, oceans act as a buffer for Co2 and other gases which are soluble in water.
There has been worldwide offshore research for over 30 years measuring ocean CO2 content and the conclusion so far is that it is a complex problem requiring more intricate models taking ocean currents and stratification based on ocean depth into account.
But nobody is saying "Oh the oceans are saturated with CO2 and the sky is falling".
Should we cut back on fossil fuel dependence?.. YES Should we stop slashing down forests?... YES. Should we move towards alternative energy and transportation methods?... YES
Should we let the Government waste shitloads of money to figure this out?... FUCK NO
So my point is we can respect and understand science while at the same time NOT let our politicians force us into unproven technologies which at the same time create significant economic problems.
Politicians have turned this into another money laundering scheme just like the war in Ukraine.

I'm actually all for nuclear reactors. Just make them safer. Just that word freaks people out. But from what I hear, it's clean.
|
|
|
A well known billionaire sunk a small fortune in to Nulear power and developed what would be considered safe nuclear reactors. Unfortunately right as he was about to find a site for his first plant... Fukushima happened and the project has been tabled ever since.
The difference between the Fukushima reactors and this newer technology is night and day... but we aren't going to change anyone's mind after it has been made up these days.

More fundamentally, I'd like to understand how many people the earth can sustain efficiently without upsetting the ecosystem. I feel we are way beyond that point and we are crapping out new humans at a prodigious rate.
Also, on a somewhat related vein, what about using homeless people as a power source as in the Matrix? Win-win.

“Should we cut back on fossil fuel dependence?.. YES Should we stop slashing down forests?... YES. Should we move towards alternative energy and transportation methods?... YES

==============
? We give a blank check to government to fight wars. It’s seen as one of the basic functions of government. What is the difference here?
World governments fought the depletion of the ozone layer in the 80s. They let scientists decide what actions needed to be done. Governments put the plans in motion.
This is one of the very basic functions that governments need to perform. Protect its people from all forms of threats. Present and future.

Apparently no one's realized that Sagan went before con-gress in 1985 - so almost 40 years ago.
In that time almost nothing's been done to significantly reduce the amount of green house gasses we produce.
Sagan stated that it would be likely, according to the data in 1985, that we'd see a rise in global temperature of several degrees Celsius by the 'mid to end of the next century'.
Well it's early in the 'next century' and we're already seeing localized and global temperature increases as well as localized and global weather patterns being drastically changed.
That means we're ahead of Dr. Sagan's timeline and the time we have to do something is rapidly shrinking and the timeline is no longer linear, it's exponential.
Instead we've got people denying it's even happening, people worrying more about what would happen to the economy etcetc.
Proving that people really are idiots.
BTW no one really knows what the Carrying Capacity of the earth is but judging by the evidence the over population by man has exceeded it.
Just because the amount of resources available aren't enough to sustain the current population much less more unchecked growth.

I should add we already paying for climate change already.
With the historic heat & drought in West, flooding disasters in the Midwest, and soon to be hurricane season in the East Coast.....we Americans are paying up the ass in disaster relief.
All these disasters are getting stronger and worse. So when you say that government shouldn't spend a shitload of money to fight climate change.....we already are paying a shitload by doing nothing.
|
|
|
How have local and global weather patterns been 'drastically' changed?
We get several hurricanes every year... been going on for centuries.
We should switch to nuclear and figure out how solar and wind can effectively support the grid which it's NOT doing right now.
Right now Progressives have all but shut down nuclear, mandated all EV sales by 2035 but are told not to charge EV's. This all while there is complete war on fossil fuels.
The threat to our climate is from politicians who are in China's back pocket to buy EV parts and solar panels.
The threat is the dumpster fire burning at 1600 Pennsylvania Ave.

@wunanddun It's funny that the well-known billionaire if whom you speak is the same man that so many conservatives accuse of embedding microchips in vaccines. They've also accused him of advocating genocide, probably because of exactly the same TED talk where he first unveiled this new reactor technology and investment.
|
|
|
^ true dat.... he can be wrong about some things and right about others....Some of his work has been great some might be questionable...I don't pretend to know... but no one has even touched a his nuclear reactor plant specification cus of what has happened with reactors that in no way resemble his reactor. Ohh well....
|

@jackrabbit It's also funny to see how you seem to lionize Sagan when he conveniently supports nuclear power. In truth, he was an outspoken atheist liberal that you would probably shoot on sight in any other context. How do conservatives constantly fail to see the utter hypocrisy in their lives?
|
|
|
MR. Finch the US has led the world in greenhouse gas emissions reduction since 2005.
|
|
|
TerraPower is still around, but it's slow-going. I'm rooting for them to succeed.
|
|
|
And let's be clear. If he were alive today, Sagan would almost certainly be ripping conservatives new assholes, in a way that only he could verbalize
|
|
|
USC 41 Stanford 14
Sagan is a smart guy. If he was around he would be focused on the proper policies.
He supported nuclear and he would be ripping LIB's a new one for not having a more gradual taper of fossil fuels when there is no clear other winner yet.
|
|
|
And ripping them another for phasing out nuclear
|
|
|
^ Perfect example of conservative cognitive dissonance
|
|
|
And Jackrabbit has just acknowledged that politics to him is more important than his precious religion. Sane minds can disagree on politics and technology. But Sagan was crystal clear that theists were fooling themselves.
|
|
|
My precious religion?...
How does that come up?. I dont go to church
|
|
|
^ If so, then you're a bad conservative. You must be a RINO if you're not religious.
That's not me talking. That's the view of the vast majority of conservatives.
|
|
|
^ Stay on topic bonehead.
|
|

Atti, TY for this video. I have been learning about this topic for a while. SAGAN was clear this situation is all our problem. I see it now how things are changing both here in the South and when I visit Cali. Scary!

They Blew it up, cause they don't want you to know that a population of 500 Million ought to take care of Climate change.
Your Fifth booster is waiting for your.

I get a kick out of people who say "we ought to do this" or "we ought to do that." I have solar panels on my roof, drive a hybrid car, changed my entire landscaping scheme to drought tolerant with drip irrigation, and have almost 400 gallons of rainwater collection storage.
If you think that we need to do something about our poor stewardship of this planet then take some proactive measures. It doesn't take much as an individual, and your individual contribution to the overall solution to this problem may seen insignificant, but if enough of us make a commitment to do all we can the cumulative results could be amazing. Who knows, might even make our planet tolerable for your grandchildren, or their grandchildren. But as it stands now, we are on track to leaving them a pretty fucked up mess!

BTW - you don't need to be "left" or "right", a conservative or a progressive, an American citizen or a migrant. It is a global problem that will require a global response. We can leave it to governments, then complain about how they did it wrong, or we can make the effort ourselves and at least feel good about our contribution.

I eat at Taco Bell everyday and the only reason is because it gives me gas and that I can contribute to global warming. With hope and God's will global warming will cause all the whiny ass man b****** on HX that explode into flames because of course they're already flamers an when this his happens America will truly be great again because all the whiny ass man b****** will be turned into dust or charcoal or Soylent Green

And Marrisa you need to get your beautiful behind out of San Diego and head north.

@Marrissa, Why, then, are climate change deniers almost exclusively conservatives? We all need to do what we can, but some things can only be accomplished with a collective effort.
|
|
|
Climate change deniers are almost all ways conservative? Funny, those on the left who believes science has proven climate change are the same people who believe a man can be a woman and a woman can be a man when there's no science to back up their claim. It's all about the way one feels.

Heatwave index over past 120 years. There is nothing "dramatic" happening other than a subtle shift in long term warming of 1.2 degree Fahrenheit. Last peak in 1930's caused the dust bowl.
Meanwhile there is ZERO science showing that men can get pregnant.
But it is astonishing that 36% of white female college educated women actually think men can get pregnant. These are the dunces that want us to pay for their degrees.

Besides being significantly closer to the sun that Earth is, Venus also does not have plate tectonics to any significant extent. So Venus has no mechanism for locking up carbon and recycling it through crustal subduction.
Hot Venus =/= hot Earth.
Nuclear power + fuel cells: better than unreliable solar/wind + batteries + G$$$ going to China.

Holy crap, depressing blogs are always good for a laugh!
It's always wonderful to have ones low expectations of one's fellow humans be realized post by post.
Some of the dumbest fucking posts in this blog in the 15 years I've been on this site.
Thank you, thank you for making it all come true. ).gif)

Whe. The petro dollar crashes the least of your problems will be your carbon footprint... and that's gonna happen a lot sooner than the oceans rising and 120 September weather.

Did I miss the change in TOS that allows posting references to DNA clones?
Been seeing this in posts every now and then and the mods just let it go.
wtf?
PS Don't reproduce, then your clone won't be facing the dire future you've painted. Problem solved.
PPS Rewatch Carlin's bit on plastic and the planet. All your answers are there.
Stop global warming, reduce your carbon output!
Kill yourself, sooner is better than later!
And, save the gay whales for Jesus!
Here's laughing at you

I'll put it this way. Met your new King. Pay close attention to the Blood line.

The thing overlooked in this blog is how a sudden cutback of fossil fuel production also impacts Petro chemical and fertilizers.
aka food shortages
That coupled with the "magical coincidences" of dozens of food processing plants burning nation wide which gets very little media coverage.
There is deliberate sinister shit going on.

^ True. But we can still use petro chemicals for fertilizers it's the burning where the problem comes in. We can start transitioning away from petro chemical fertilizers slowly and move back to 'natural farming' - studies have shown that yields are actually higher then petro chemical fertilizer farming over a 10 year period.
It's the corporate farms that would be against this the most and companies like monsanto.
I don't think it's a 'get rid of the internal combustion NOW' or nothing, but should start the transition, better late then never. Even a 50% curb would be an improvement and it would give the economy time to adjust.
Personally I don't think teslas or the other electrics are the answer but might be a part of the solution. Lithium mining and refining still pose a problem.
I'd really like to talk to Bob Lazar about his hydrogen car and see if it really works. If it does it may be another part of the solution and a bigger part then the ec's cause all it would take is a retrofit on current vehicles, so people would only have to get their current vehicle reconfigured instead of spending $80k on an ev. People would be more inclined to do that then spend the $80k. Course your water bill would go up cause you'd be filling up your car every couple of days.
The real problem is getting the other countries to cooperate and make the transition as well. China and russia and the 3rd world aren't willing to make any changes, or at least don't seem willing. But the U.S. is still the biggest contributor and although we've made some strides there's a long way to go. But can't do it without the rest of the world, like Sagan says this is a world crisis not just a national one. Well that and the opec countries and petroleum companies like bp and conoco.

Dr. Sagan and other scientists had warned the world about the increased CO2 concentrations in the atmosphere since I was in high school in the 70s, Exxon paid to study this phenomenon and then decided to bury the data due to the negative impact on their petrol business, as well as the Koch brothers - the fossil fuel industries big money won, and now we're experiencing the initial consequences of the fluctuations of unstable global weather systems. Even Hollywood got it right in Soylent Green and Blade Runner. I hope humans will be able to reduce this rate of change in time, I'll be okay for the remainder of my life, but I worry about the world my kids and their kids will have to live in. Earth will move on, as there was a period of a carbon-rich atmosphere 2.7 billion years ago, but humans and the flora as we know it may not.

How have local and global weather patterns been 'drastically' changed?
==================================================
I don't know but 2 weeks straight of 100+ degree heat in Los Angeles is pretty drastic.
The lush farmland in Central CA turning into a desert is pretty drastic.
Colorado river going dry is pretty drastic.
Lakes in the west disappearing in a matter of years is pretty drastic.

^ so here is an idea for you. Simple remove your carbon footprint from the planet by taking your own life. Mother earth will thank you and so will the member of HX. Good bye and good luck.

@Fuckbear
Ask you before...what are you doing here? You not here to get laid. So are you just a shit talking snitch?
|
|
|
^are you an idiot or do you just play one in real life
|
|
|
And I bet you make all the ladies of HX wet with desire
