TRUMP 2020!

[Leo the Conqueror]

Actually I think Dman has and Dez is pretty close by saying that the only climate change is the change of seasons.

Kim - there is a great deal out there to support both sides of the argument>If you only read one point of view you will not educate yourself to other possibilities. EG: If you only read info that supports something then your view is biased. It is wise to read both for and against before making up your own mind. Read everything. Not just what suits your opinion or the way you want it to be.

Climate change is an overview of the general ambience and could be called a big wheel. We seem to all agree on this.
Weather is what you experience every day - if the sun is up or if it is raining and windy etc.
And weather would be described as the wheel within the bigger wheel.

Climate change has always been and always will be. The changes are more extreme but slower over greater period of time. And happen on a number of planets.( Don't include planets with internal warming systems.)
Weather changes nearly every moment.

"In many ways Venus is Earth’s twin planet. It’s only a little smaller, and made up of the same composition as Earth. But when it comes to climate, Venus couldn’t really be more different. Venus is a hellish world – the hottest planet in the Solar System, with an average temperature of more than 400°C, and a surface pressure almost 100 times what we experience here on Earth. On top of that, there are clouds of sulfuric acid and other corrosive chemicals. Visiting Venus would be the worst vacation ever." https://www.universetoday.com/36296/climate-of-venus/

"Its clear that the world was warmer during medieval times. By mapping the data published (all peer-reviewed) by 752 individual scientists from 442 separate research institutions across 41 different countries, and correlating their comparisons of temperatures changes since medieval times, after factoring in the fact that these studies use a range of ice cores, stalagmites, sediments and isotopes, we find that temperatures were about 0.5C warmer worldwide.

Prior to IPCCs third assessment report of 2001, the accepted depiction of the prior millenniums warmth was that published in the panels 1990 maiden assessment global temperatures had fluctuated drastically over the period. And data derived from sources including tree-rings, lake sediments, ice cores and historical documents bear out that position. Indeed, its abundantly evident that since the last glacial period ended, over 14,000 years ago, the Earths climate has undergone multi-century swings from warming to cooling that occur often and with remarkable rapidity. And not one but three such radical shifts occurred within the past millennium.

The years 900-1300 AD have been labelled the Medieval Warming Period, as global temperatures rose precipitously from the bitter cold of the previous epoch the Dark Agesto levels several degrees warmer than today. A sudden period of cooling then followed and lasted until the year 1850. This Little Ice Age brought on extremely cold temperatures, corresponding with three periods of protracted solar inactivity, the lowest temperatures coinciding with the quietest of the three (The Maunder Minimum 1645-1710). And then began the modern warming period, which, by the way, many scientists believe ended with the millennium itself."

I think this answers your question as why we 'dont believe'. Not that anyone actually said that.

edit - sorry, I should not have said "we" - I can only speak for why I am not caught up in the GW hype.

Argo brings up a fantastic points. Which I also brought up in less of a documented and more anecdotal form. Here is my problem, there are groups of people who know without a shadow of a doubt that we are doomed and we must act now and if you dont believe it too you are science deniers. But, when you bring up the things that I and others have said to include all the scientific data Argo just provided, its crickets followed by a quick canned global emergency response.

They only want to believe the science that tries to predict the future, not the science that has been observed and actually documented. Its become a religion of its own based on a belief system that is a moving target.

60's - the ice age is coming
70's - the ice age is almost here... be ready!
80's - the ice age is just about here, what ever will we do?
90's - Temperatures are up, global warming is running rampant
2000 - Global warming will kill us all
2010 - Global warming is now climate change since the temp swings - we are all gonna die
2020 - Climate change will be killing off all trees by 2050 and all cities will be underwater even though there isnt enough ice left to do it. believe BELIEVE!!!! $$$$$$

Edit - A thought on Venus - People like to use it as a supporting argument because they say it has a runaway greenhouse effect. The atmosphere of Venus is mostly carbon dioxide 96% compared to earths .04%, which is a very heavy gas. ... At the surface, it is under 90 times the pressure of Earth's atmosphere. This compresses more of Venus' atmosphere into a given volume, also making it denser then you add that it is 107 million miles closer to the sun allowing it to receive 2600w per m/2 of energy vrs the earth at 1300w per m/2 and you can see why the Earth can never be like Venus!

Just another scare tactic by the uneducated This is why you cant just hunt and peck at the "in topic" on social media, you have to look holistically to see the big picture.

never said it wasnt happening
my doubt is the degree and the cause
i prefer to listen to folks not spending tons of free cash
anytime people give data that comes with hands out for more cash i see the possibility for tampered data

[The Lamb]

Im with you...

Kim and Blue, what you should really be scared of is the levels of dihydrogen oxide in the atmosphere. Its the number one greenhouse gas by a large amount , and talk about a positive feedback loop! The warmer the atmosphere the more dihydrogen oxide can be held in the atmosphere which makes it warmer which allows more dihydrogen oxide till the system collapses and the planet gets pummeled.

The increase in dihydrogen oxide is solely responsible for ALL hurricanes and ALL major storms and ALL flooding. The only saving grace is that with every large storm comes evaporative cooling reducing the temperature till the next major increase of dihydrogen oxide.

Its how the earth turns on the AC. If i were you i would focus all my effort into stopping the proliferation of dihydrogen oxide. You can read it in my new book, "dihydrogen oxide and you, why we should fear water" on sale on Amooozon for $20.50. Only avilable for download, since trees are all gone at that price

What effect will oceanic thermal expansion have on coastal cities due to our 'overall rise in average mean temps ?

[Most Lee Harmless]

We can build a wall! Mexico will pay for it!

[Lachlan]

Kim, for the last time not one person here has said that climate change doesnt exist, the only question is how much humans are actually playing a part and how much we are playing a part and we aren't gullible enough to spend $30 on a book to tell us all the trees will be gone in 30 years.

So just answer me one question. According to scientists that have done sampling of the bubbles in Antarctic ice cores, we have about 200% more Co2 in the atmosphere than we did during the last interglacial period, and if that is the big bad wolf here, then why are we still 3 degree C cooler than the last interglacial?

Yes, correct answer is IDK. So the issue that that most of us are having is that with levels of Co2 at about 480 ppm we are still colder than last time earth went through this, then maybe Co2 isnt as big a part in the cycle and more an effect of the cycle (normally) but one that humans added to.

If that be the case, then that means that there is something else controlling the temp on the planet and it aint us. That doesnt mean we havent added to it, it just means we have no control over it... and that scares some people, plus the government wont pay for a paper that says "yep its happening, but nothing we can do"

someone said it was just a theory I remember

wonder why we have never been taught about that particular gas because it seems like mostly carbon dioxide is talked about in schools being the main one

What effect will oceanic thermal expansion have on coastal cities due to our 'overall rise in average mean temps ?

Well, I imagine not much. I say that base on one thing. What is a hurricanes purpose, if you can think of it that way? To transfer energy. All heat is is how energetic are the atoms right? So a hurricanes goal is to transfer energy from the equator when there is an abundance, to the northern or southern regions away from the equator region where there s less. Its a balancing act.

Thats the reason so many have been predicting increasing hurricanes, the problem is the predictions are not playing out as we have had less hurricanes than they did pre 50's when it was a little cooler. Strange huh?

So that why i suggest not much, i would say if the average (not just local) water temps rise to a point of some sort of thermal expansion, she will cool it down with more tropical and sub tropical storms to loose the heat (energy). Also dont forget about convection cycles in the deep ocean as well as ocean currants.

Fun fact - Did you know that in the thermosphere 100 miles up, the air is 4500 degrees F. Luckily the air is really thin so we would feel it as cold. Like i said, heat is only energy and 100 miles up we get alot of energy from the sun
