The climate change debate continues.

Simply put, the planet is 4.5 billion years old. Life began about 3.8 billion years ago and from that point till now sediments and material from live organisms that died have been producing fossil fuels. So in the last 2-300 years & more so in the last 100 years humans have been burning it and emitting all the waste in to the atmosphere.

 

The jury is out as to how much we have left but estimates are that we have burned our way through about 50% of the energy stored in fossil fuels in the last 200 years that took 3.8 billion years to create & what is left is getting harder to extract. 

 

Still we have people who deny that chucking the waste from burning fossil fuels in to our atmosphere is helping to change our climate, now very rapidly.

I have a copy of the American World Almanac and Book of Facts, for 1975 (published 1974). It's full of interesting and majorly diverse subjects, and in amongst the mind-boggling array of information, one scientist makes the point that continuing to burn fossil fuels at an ever-increasing level will almost certainly lead to global warming. That's from a scientist from over 50 years ago.

 

The problem that many fail to see is that fossil fuel production and use has continued to increase every year for over 125 years. When there was only a relatively small level of production and use, the effects weren't felt. Now that fossil fuels are consumed at huge and ever-increasing levels annually, at some point, we have to say, "Enough!".

 

Besides, I don't like giving vast amounts of money to already-super-rich fossil fuel producers and retailers, and I don't like what the oil-rich countries do with my petro-dollars.

Trump says it is all a hoax, so given that he lied more that 35,000 times during his first Presidency and that the fossil fuel industry was one of his major backers (Big Oil gave him $445 million alone) during the election campaign for his current presidency, he must be right. Yeah right.

"Trump will FIX it"  SO HE BENEFITS.   (Like FIXING a race.). Nev

FAKED by enlargement so it looks as if the sea hasn't risen. Nev

Any 2 pictures that compare sea level must be taken at the same point in the tidal cycle. 

More importantly, the sea level is not the same throughout the world.  Factors such as wind, currents, precipitation and  the distribution of the world's mass. 

 

Are sea levels rising the same all over the world, as if we're filling a giant bathtub?

No. Sea level rise is uneven, the two main reasons being ocean dynamics and Earth’s uneven gravity field.

First, ocean dynamics is the redistribution of mass due to currents driven by wind, heating, evaporation and precipitation. For example, during La Niña events, sea level goes down because some rain that usually occurs over the ocean shifts to land, and the same phenomenon produces low latitude currents that redistribute seawater. Regional climate cycles, like El Niño and La Niña, and longer-term effects, like the Pacific Decadal Oscillation, change ocean circulation, which changes sea level.

Second, because the distribution of Earth’s mass is uneven, Earth’s gravity is also uneven. Therefore, the ocean’s surface isn’t actually a perfect sphere or ellipsoid; it is a bumpy surface. As the land-based ice sheets of Greenland and Antarctica continue to unload their mass (lose ice) from far above sea level and far from the tropics, that mass reaches the sea in the form of meltwater that is then redistributed along Earth’s gravity field.

So rising or falling sea levels could be because of those same reasons.

Well yes, if you are just relying on pictures, however, this is not how mean sea level is calculated. Mean sea level is measured through a combination of gauge data from around the world and satellite altimetry.

 

The data is readily available, and the question I would pose is, if you believe the data is incorrect, then what do you believe is the reason?  Are  NASA  and CSIRO etc., incompetent or lying or perhaps part of a plot to bring down capitalism because they are such hippies?

 

How Do We Measure Sea Level?

The Later Picture has been taken at a higher angle and closer The ICE has reduced and the Proportion of Land therefore appears greater. The top has gone from the Lighthouse. It all contributes to an Illusion. Plus all of the Possibilities and variations Mentioned. The tidal Movement at Broome is 27 Feet. Just imagine the fake effects you could produce there. The Oceans ARE warming so  the volume of water expands. AS well melting land ice adds to the Volume. Nev
