Global warming or is it an Ice Age?

Didn't you get the memo? We changed the moniker to climate change so we could still blather on about how humans are destroying the environment and we need to tax them all to death to fix it.

Yes, let us ignore all of the record heat levels being set for everywhere else in the world and only focus on a single part of the USA.

History has shown that over 10 year periods we can see increased storms and it varies so it's not 10 year's exactly. Many factors affect the weather but we do not have enough data as to how weather patterns can affect over longer periods. So all we can do is jump to conclusions over what is causing the weather.

My answer is that we are a small piece to the pie and humans think they are bigger than the earth. The earth at any time can erupt a massive chunk of crust at the ocean level shooting massive amounts of magma that it reaches outside the earth's atmosphere and send a tsunami the size we could never imagine and change the course of history wiping out nations and killing billions of people.

We cannot control the weather nor can we control it. We might be contributing to the problem, or we might not be. Nobody really knows and nobody will ever know until you include every variable into the equation.

As you can see this happened in 1869, because if it didn't then there would be no record to break.

Save it for the political talking bobble-head shows.

People who point to a single weather event or year-long pattern in one part of the planet as "proof" for or against global changes don't know crap about the science.

They also apparently don't even know the definition of climate as used in scientific study and discussion. I place no stock in their rants.

The interesting part of this is, "Global Warming" can / could be a cause of heavy and / or unusual snow storms.

Keep in mind, for snow to come down, moisture has to go up, for the most part the going up occurs where it's warmer then moves into a cooler area to fall as snow.

In spite of all we think we know about what causes what with the weather changes and climate shifts, Mother nature still has many secrets she hasn't reveled.

Who knows, this might really be a sign of global warming.

Ah yes, pretty graphs! C'mon, no one's mind is getting changed here...

Looking back a little further than 1880:



Hmmm, wonder if that enormous, virtually unlimited source of energy that keeps our planet habitable has anything to do with this?

This graph do not answer one main question. Is .6 temperature increase big deal in big picture? Being graph is only till 2000 what have happened between 2000 and now.

reply to IIIBradIII
To the best of our knowledge, based on the ice cores, current average temperatures are the highest during the last 800k or so years. And the issue isn't just temperature, but it's the rate of increase in the last 20 - 30 years.

reply to IIIBradIII
And BTW, care you enlighten us of the sources of your graphs? The first is a little different from what I normally see from trustworthy sources, and the solar iiradiance figures are a little suspect because the equipment needed couldn't possibly be there until very recently, though there are proxies.

quote:

Variations in total solar irradiance were too small to detect with technology available before the satellite era
[...]
There are no direct measurements of the longer-term variation, and interpretations of proxy measures of variations differ. The intensity of solar radiation reaching Earth has been relatively constant through the last 2000 years, with variations of around 0.1-0.2%.

Some of this may be self correcting as time goes on, one of the primary correction factors is cloud cover. As the earth warms there is more cloud cover, the more cloud cover and the more heat that is reflected back into space.

On the flip side of that the more cloud cover, the more nasty weather for those below the clouds. So while it may self correct we may not like the results of the correction factor.

Venus has pretty good cloud cover, and it made into a hellishly hot place.

Yes we Cain!

For a long time, based mostly on the distance from the Sun, Venus was assumed to be similar to Earth with liquid water on the surface. And it still assumed that initially this may have been the case, but a runaway greenhouse effect turned it into a hellhole.
It's a shame because it would make a pretty nice planet, but now that it lost most of its hydrogen, even if we were to deploy giant sunshades around to cool it down, terraforming wouldn't be possible without hauling in some hydrogen. It has a mostly CO2 atmosphere, BTW.

Does help that Venus has a day that lasts 243 earth days.
