Does Pavement "Black Top" contribute to Global Warming?

I live in a mountain valley and pavement and roofs make more of an inversion for the air.  That means the dirty, cold air stays low in the valley and cleaner, warm air goes right across.  It takes a strong wind to move the dirty air out and bring blue skies and sunshine back. Burning wood makes it so much worse, too. \n\nI think that undersea volcanoes are adding way more to global warming than human activities.  \n\nHave you ever seen this website: www.iceagenow.com?\nThe climate always changes, but we don't know how it all works yet.

Global warming\nFrom Wikipedia, the free encyclopedia that anyone can edit\nJump to: navigation, search\n \nGlobal mean surface temperatures 1856 to 2004 \nMean temperature anomalies during the period 1995 to 2004 with respect to the average temperatures from 1940 to 1980Global warming is an increase in the average temperature of the Earth's atmosphere and oceans. The term is also used for the more specific scientific theory of anthropogenic global warming, which states that much of the recent observed (and projected) global warming is human-induced and the result of a strengthened greenhouse effect caused by man-made increases in carbon dioxide (through the burning of fossil fuels and deforestation) and other greenhouse gases. The natural greenhouse effect keeps the Earth 30 °C warmer than it otherwise would be; adding carbon dioxide to an atmosphere, with no other changes, will make a planet's surface warmer. Current research tries to uncover more details, e.g. about positive and negative feedback mechanisms, to allow a more precise quantification of the effects of global warming.\n\nTemperature change is just one aspect of the broader subject of (human-induced) climate change. The scientific opinion on climate change, as expressed by the UN Intergovernmental Panel on Climate Change (IPCC) and explicitly endorsed by the national science academies of the G8 nations, is that the average global temperature has risen 0.6 ± 0.2 °C since the late 19th century, and that "most of the warming observed over the last 50 years is attributable to human activities". A small minority of qualified scientists contest the view that humanity's actions have played a significant role in increasing recent temperatures. Uncertainties do exist regarding how much climate change should be expected in the future, and a hotly contested political and public debate exists over what actions, if any, should be taken in light of global warming.\n\nBased on basic science, observational sensitivity studies, and the climate models referenced by the IPCC, temperatures may increase by 1.4 to 5.8 °C between 1990 and 2100 [1]. This is expected to result in other climate changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, or contribute to biological extinctions. Although warming is expected to affect the frequency and magnitude of these events, it is very difficult to connect any particular event to global warming.

Yes.  Global Warming is occuring.  It will just keep getting worse if we don't take measures to try and prevent things from getting worse.

Global warming and it is closer to the equator.

In rather indirect ways, yes.\nRecycling paper helps save trees (recycle a little bit, save "part" of a tree) which convert carbon dioxide into oxygen.  (Carbon dioxide contributes to the greenhouse affect)\nMy driving style is geared around saving gas.  Mostly to save myself money, but even if I become very wealthy, I'm still going to be a bit conservative in my driving- still gonna get a hybrid, albeit a more powerful one.  Save gas, less emissions into atmosphere that contribute to global warming.\nOne person can't stop global warming alone.  However, each person can help a little bit, and it'll all add up.

Partly.\nThe increasing emission of Green House gases in causing Global warming which is making the world's climate go topsy-turvy\n\nNow you have Summer heat waves in Europe, Snow fall in Dubai, the killer Hurricanes\n\nPerhaps it is time for Mankind to step back and think as to why these are happening\n\nBut I should state that Earth Quakes are not quite related to this effect (but then again, you would never know)

global warming is cause by greenhouse gases being trapped near earths atmosphere, which causes heat to be trapped nearer to earths surface which increases the temperature on earth slightly which melts the polar ice caps which makes water levels rise which means islands will be flooded and shores will advance into the land making living space smaller in an already overpopulated world.

Dramatically. This green house gas has shown a sharp incline, althought I am not sure about the numeric details. An easier way to notice the increase is to appreciate the increase in global temperature over the years.

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades

Global warming caused by humans is a myth.  It has been debunked by scientist after scientist.  The reason the earth is in a "warming cycle" (the temp on earth has risen 1 degree in the last 100 years..1 DEGREE) is because the sun is hotter.  \n\nThe environment is the new "religion" of the left, both in America and abroad. They don't believe in God and hate America.

Any energy liberated by a reaction is indeed heating up the planet.\nHowever, the real problem with global waming is the amplification caused by green house gasses, like methane and CO2, wich traps the heat from the sun.  The sun gives about 1300 watt per square metre, over the surface of the planet this is over 10000 times more energy than all the installed power (the sun energy hitting earth is equivalent to 27 gigawatt per person on the whole planet; no one uses that much power). So, doubling our power production would have a negligible effect on global warming, but adding just a bit of gas that traps the huge amount of power that the sun sends will, however, have a huge impact.

NO because of all the new cars and fossil fuel that people are burning. because of that the hi concentration of Co2 in the atmosphere Will result in global warming. In the last 100 years the global temperature has GROWN by 1 degree Celsius. and in the next 50 years or so the temperature Will rise by another 3 degrees resulting in freak weather.

No.  If the planet were on a cooling trend, and stayed that way for a while, it might be heading towards a periodic Ice Age, as it has done in the past.  We would consume a lot more of outr limited energy resources just to keep ourselves warm.  Also, don't worry so much about Global Warming.  As I said before, nature goes through these cycles of warming and cooling.  Yes. humans have an impact, but it is small.

Global warming caused by increasing holes in the o-zone. This is caused by pollution, such as car emmissions, and chlora-flora carbons.

Global Warming is cause by solar activity.  The increase in the number of sun spots causes the earth to warm.  The temperatures were hotter in the 1920 than now.  The hurricanes were also just as bad then as now.  A rise in CO2 from 1/4% to 1/3% in the atmosphere has no impact on global temperature.  The scientific community has only been accurately measuring temperatures for 30 years.  The only validated temperature measurement of the earth is from the polar satellite.  In 30 years it has only seen on temperature anomaly.  A rise of 1/4 of a degree caused by the full moon.  No other measurement system has shown the accuracy to measure this rise.  Therefore they are not! The polar ice cap has only been watched for 30 years by satellite.  No one measured it before, so how can they say it is now melting for all time.  They don’t know, they are drawing 1000 year conclusions with 30 years of data.  Not possible, not valid.

The earth has historically gone through cyclical climate changes and we my or my not be going through one now. As to what is causing this, we can only speculate. I don't think that all of the SUVs or hair spray in the world is going to change our climate.
