Have you ever walked barefoot across a road during a hot summer day? Have you ever tried picking up a metal??
object laying in the sun at noon? Have you ever walked barefoot across a
road at night? Well, we are paving over countless acres of land through
roads and parking lots, we are continually building steel and brick
buildings, asphalt covered roofs on homes, not to mention how much
deforestation is going on. Are we slowly warming up nthe temperatures
through this progress as it is called. Roads, parking lots, and buildings
hold heat all night until the next day when the sun heats them up again, SuperMalls, huge city practically paved from end to end all over the world, replacing nice, cool, grassy meadows or forests. Has anyone ever considered this?
yes to both
I walked barefoot on the pavement last summer when temperatures
hit 40C/104F for the first time in recorded history, which was warm but not
too hot; this year we had some nice days in spring but now we have rain,
wind & 60's. The global warming sure isn't only causing heat, the climate
is going haywire but right now I would like to notice some of the
*warming*!
I don't think the pavement is the greatest problem trapping the heat, I've always learned the greatest problem were the exhaust from cars, the pollution from factories, the thinning ozone layer, & this didn't even come into it. but maybe in areas of warmer climate the asphalt trapping the heat is more serious than here. In a normal summer we only have a few days of 'heat' (relatively speaking -80 is & 90's).
Are you people retarted? First off, there have been many
scientists in the past couple years who have proven that the sun goes into
periods of brightness where its temperature increases & decreases
periodically, therefore, the sun is currently in a cycle which is the
reason that this so-called ''global warming'' is occuring. Of course all
of this construction & paving is retaining heat.but the reason is because
of the cycle that the sun goes through. You may not know this but 20 years ago, the same people who now claim that global warming is presently occuring, claimed that we would be going into an ice age by the year 2000. Well, in 20 years the suns temperature will obviously fluctuate & at some point will decrease causing less of the heat to be retained by the construction. But yes, I do agree that we should not go overboard with the construction, but then again there is the effect of over-population which causes all this construction.so thats another story. But most people if not everyone knows about the Live Earth concert which is trying to raise awareness that global warming is happening.but this really isn't the case, so in reality its just another gimmick from the Democrats to try to win votes from the ever-manipulative liberals who are always right about everything.
Yes. This is totally part of the 'problem'. More and more
pavement does retain more and more heat, in more and more places around
the globe. It is one small part of global warming.
Factor in the ''urban heat island'' effect as part of the ride
in global temperatures. Temperature stations that used to be rural are
now in urban & suburban settings. Do you realize that one of the most
common places for temperature stations is at airports? Used to be that we
actually had valid reasons to monitor meteorological/climatic conditions.
Monitoring immediate & longterm trends at airports seemed only natural for
safe operation from day to day, year to year. What has happened to airflight after WWII? What typically happens around an airport that once was a landing field on the outskirts of town? You got it - commerce. Urbanization. So what do you do now? How can you relocate a station to an area that does not reflect falsely increased temperatures, but still retain continuity with previous direct measurements? Short answer: you can not. But instead of modelers telling you that they may be wrong seeing how they had to make a best guess adjustment, they just give you their findings, tell you that everyone agrees, & accept it on ''good faith.'' Right. Either way, research is being done on the use of lighter colored aggregates in road use, although it is mostly from the angle of increased visibility. Understand that the lighter colors would lead to increased glare, driver fatigue from the increased light, & possibly decreased ability to retain the warmth necessary to keep roads clear of snow & ice.
Would you feel better if we painted all asphalt roads white?
no walking across a paved road in summer when it is hot would
be stupid. did you ever stop to consider that the huge body of water that
we call the oceans might be having a effect on the temperature? after all
it reflects heat back into the atmosphere? there is way more to th so
called ''global warming'' than you, i , or any group of scientists will
ever understand, other than people who have a reasonable capacity for
thinking realize that the earths temperature is in a state of change all the time & we have no control over it at all.
Well, the global warming nuts haven't. What you are describing
is the ''urban heat island effect''. This is a LOCAL effect surrounding
cities. Unfortunately this effect has given rise to a false notion of
rising global temperatures that throws off the computer models of the
global warming alarmists.
Interesting thought, something I never thought of before, makes
sense though. I sure hope they come up with a better way.
I myself would like it if we all had a way to get around without having to
own our own cars; that seems like an expense that is now to high for most
of us to afford.

We have, but no one wants to listen to all this
Multiply this and wallah you got a part of the equation there
too. However, many buildings rooftops are being turned towards the green
side too.
