That video with Kaku in 1991? He said Earth temps would rise between 4 and 9 degrees fahrenheit between 1980 and 2030. Can anyone look that up and authenticate it? Are we still on track to meet that target? He stated that the differnece between the ice age adn the warm period we exist in was 9 degrees, meaning that between 1980 and 2030 we would see a rise in temps somewhat comparable, resulting in catastrophic climate change.

However, I remember reading in the past few years that temperatures might be lower in the early to mid 21st century than predicted in the past, but will kick up again and be right where they were predicted to be. I can't remember exactly what the research was, but it might be tied to global dimming or something solar related like this:
www.theguardian.com - Weak sun could offset some global warming in Europe and US – study ...

However, the study said any potential weakening in solar activity would have only a small effect on temperature rises at a worldwide level, delaying the warming caused by emissions from cars, factories and power plants by around two years.
* The study written about above notes the affect on global temperatures from a solar minimum is minimal and overstated.

We need to clean up our coal. To me that's the biggest thing right now. But I don't expect any heroics. Humans are heroes every day just facing life. Life ain't easy. I'm done expecting people to be superhumans. When I was growing up, I read a lot about AGW. I hated us. I was just like a lot of you posting about how terrible humans are--and I really hated myself!! I did expect us to be superhumans at the time. We failed to meet that standard and it made me hate. I didn't know how hard this life really is and how heroic people have been in the past. Long story short, self hatred or hatred of ourselves will not resolve this. People are resolving it as we speak, doing the hard work and learning what needs to be leanred.

Last I heard, Kaku is not a climatologist and I can't find any who made that prediction.
But he is a self promoting and sensationalist physicist. I'll give him that.

Another climate change argument..


Nothing new here, same old argument and people here trying to say that it is all our fault for the climate on the planet is all our fault...

This coming from the same yahoo's that do not understand why the sun is there and making light and heat on this planet, or even why the moon is there, or why or how gravity works...

I am fixing to watch a movie, have fun arguing with each other...

swear their are at least 100 other threads on this site where by page 10, we are arguing over why the planet is warming up AND possibly the entire solar system... We have know idea why the glaciers are melting perhaps it is coming from the core of the earth...

Who the hell knows...

Not to mention these scientists, who study this bull crap get funding from governments!

So of course it is our fault..

I wish world war 3 would hurry up and get here wow...

I just get tired of seeing this crap on the top page, we have beat this topic to death, even had mods coming in cleaning the walls, had the nut bags and the whole 9 yards seeing it play out every other time this topic hits the news gets old...

Your not going to change anyone's minds their opinions have been influenced...

Don't bother

Well then thank god we dont have to worry about all this nonsense anymore about emissions and blah blah blah!

Yada yada yada. He IS a physicist. For whatever thats worth. In fact last time I checked all those physicists are self promoting. What a bunch of lame ignorant self promoting physicists. Thank god we have Phage to keep us all corrected.

Can I ask you an honest question Phage? I mean seriously, and with a serious answer hopefully.

Why do you attempt to belittle so many people in this thread that have opposing viewpoints. You suggest you are "pushing 65" and you do sound as an intelligent person, but you come across as a smart alecky troll kid whenever anyone counters your opinion. It just seems so unnecessary when this topic deserves input from all aspects of people. And those people deserve to be able to enjoy participating in a thread like this. And I cannot fathom why you do this. And you know it just isnt me. I know, I am a piece of work. Everyone is to some degree. But you act like you own the only textbook on the subject at hand. If it is the stars, points, flags, or banners, then I will offer you all of mine to give to you if that will make a difference. And I guess I am not understanding why, any insight may do wonders to the disposition of discussions you participate in.

Till then, I made my spot here as I made my point in my posts about the subject. I have no need to further patronise you and your self-important petulant attitude. It is rather sad really, unless I am missing something about you that would clarify and justify why this is.



My apologies to any others for my disrespect or rudeness percieved. I shall exit now.

Why do you feel like I attempt to "belittle" anyone. Because I challenge them? Because I ask them pointed questions? I welcome valid discussion. If someone wants to engage in a discussion I'm all for it. But don't expect to to say "well, you might be right" if I don't think you are.

BTW, I don't suppose you noticed this bit of fun:

So he and Algore have a lot in common, minus the 'physicist' thing.

I can't answer for Phage, however I can understand his perceived condescending tone.

These climate threads are full of BS posts and obvious willful ignorance. We have many regular posters including Phage who recognizing man's role in the changing climate and the need for us to do something about it. Then we have many who refuse to accept the science and flood these threads with bogus talking points that do nothing but trash what should be an intelligent discussion.

Trying to counter the denialists can be frustrating, since that crowd denies science and data and tries to 'prove' their points by making political, emotional, and junk science arguments while ignoring the data that we are currently observing.

As far as I know, Kaku is not a politician. That's a point in his favor.

its kinda like the boy who cried wolf....we were given dates when america would be under water...


When? By whom? What did they say?



been and gone with no change, we were told our winters would be warmer...yet we have seen record freezing temperatures....after a while people stop falling for it....people say now "in the future this will happen and that will happen" conveniently you will be dead when it does though so yanno....trust us were politicians an well funded scientists!


What was predicted by actual scientists, not quacks or doom porners, has come true far more reliably than that predicted by denialists. So, who should we believe now?

Let's try back in 1981, when far far less was known. The basic physics was known, and yet global observations, such as they existed then (far poorer) did not yet show warming. Nevertheless, predictions based on fundamental physics and understanding of the atmosphere have turned out to be correct.

Al Gore is not a scientist. But, for a politician, he understands more correct science than most politicians.

Which yahoos are you talking about exactly?

Actual physicists do know why the sun is there, and how it is making light and heat and the planet, and why the moon is there, and how gravity works, and they understand the contribution of radiative forcing and greenhouse gases to climate on Earth and the change induced by humans.

“Man-made greenhouse warming has [made a] small contribution [to] the warming on Earth in recent years, but [it] cannot compete with the increase in solar irradiance,” Abdussamatov told LiveScience in an email interview last week. “The considerable heating and cooling on the Earth and on Mars always will be practically parallel."


This is just plain wrong. Total solar irradiance has been measured very accurately over recent years and does not contribute to global warming in the modern observational period.

Abstract

Recent reconstructions of Northern Hemisphere temperatures and climate forcing over the past 1000 years allow the warming of the 20th century to be placed within a historical context and various mechanisms of climate change to be tested. Comparisons of observations with simulations from an energy balance climate model indicate that as much as 41 to 64% of preanthropogenic (pre-1850) decadal-scale temperature variations was due to changes in solar irradiance and volcanism. Removal of the forced response from reconstructed temperature time series yields residuals that show similar variability to those of control runs of coupled models, thereby lending support to the models' value as estimates of low-frequency variability in the climate system. Removal of all forcing except greenhouse gases from the ∼1000-year time series results in a residual with a very large late-20th-century warming that closely agrees with the response predicted from greenhouse gas forcing. The combination of a unique level of temperature increase in the late 20th century and improved constraints on the role of natural variability provides further evidence that the greenhouse effect has already established itself above the level of natural variability in the climate system. A 21st-century global warming projection far exceeds the natural variability of the past 1000 years and is greater than the best estimate of global temperature change for the last interglacial.

Won't help they don't want to look at the science involved. They Just ignore the data and scream about carbon tax credits which aren't even being done. They haven't paid attention to what Washington has been doing to reduce emissions. Because they are stuck on evil taxes that don't exist. Odd how people chose money over the future generations.
