Has global warming always been a problem?

Answer 1

Yes if every one would stop using cars and maybe take a bus or a bike or turn off your computers and lights to save energy it would probably wouldn't be such a big problem. Fossil fuels and deforestation are the problems. And all of the polar bears are losing there homes because of the global warming please help are planet. It's not a huge problem like poverty but please just keep it in mind.

Answer 2

Global means world-wide. This means carbon dioxide emissions in one country affect the whole world, and the warming happens all over the world. Similarly any efforts by any country to reduce emissions has an effect all over the world. Global warming could have an impact on many areas of the planet, should the temperatures start to warm to unprecedented levels.

A:Yes. Around 2008 some scientists began to warn that changes were coming on faster than the international panels had predicted. Also as predicted, only sooner, the world was beginning to suffer historically unprecedented heat waves, droughts, floods and storms. The sea level was rising while mountain glaciers, the Greenland and Antarctic ice sheets, and Arctic sea ice melted back, all at accelerating rates. Important ecosystems from alpine meadows to coral reefs were showing signs of stress. For the scientists, as Michael Oppenheimer remarked at Fordham University conference on climate change (New York, Jan. 25, 2008), "Seeing their own predictions come true has been a frightening experience."

Global warming is a global problem that requires a global solution. Nations can not expect the solution to come from other, possibly more altruistic countries, while they take a free ride.

A:the good news is that the Earth is in far better shape that a few were proposing and people need not live in fear.

Answer 3

No. We just came out of an ice age some 50 thousand years ago. Humans did not begin liberating fossil carbon in large quantities until the beginning of the industrial revolution, beginning about 1700. From 1700 to 1900 atmospheric CO2 rose 10 parts per million. Had we continued using fossil fuels at that same rate, CO2 would now be 290 ppm and we would not reach 300 ppm until 2100.

Many scientists consider 350 ppm to be the maximum sustainable level for CO2, which at the 1700-1900 rate of consumption we would have reached in about a thousand years.

However, our use of fossil fuels increased at an exponential rate, doubling about every decade. We passed 350 ppm in the 1980s, and will exceed 400 ppm in 2015. By 2050 we will pass 500 ppm.
