We're going for alternative energy source because we're running out of oil. Why would you even relate global warming to alternative energy? Even if we go whack with all the gas, oil, and coal we have left in the world- it won't change a single bit about your life, your weather, and your kids. But we don't go whack with it because if we ever run out of oil before the alternative energies arrive, we're doomed to lacking energy and all the transportation of consumer goods. (and even the ability to make any kind of goods) And we'll be hit with the biggest possible inflation world has ever faced and millions will die because of that. Thats why we're trying to come up with alternative energy.
Global Warming is, happening no matter what. No matter what we do, it happens. Although theres a possibility to cool Earth down by sucking up CO2 to normalize the levels. As without the greenhouse effect, warming becomes impossible to proceed after certain points.
And the only alternative fuel that seems promising to us is Fusion. Others seem to either cost huge fields of land, or massive food price sky rocketing, and huge environment killers.
Solar energy DOES take up huge fields but environmentalists have to let them proceed with permission or they sue, geothermal energy doesn't do that or make food prices skyrocket, nuclear energy mostly hapopens high north in the cold, wind energy is a jgiant pole, and biofuels? Biofuels is basically weeds. Animals and other envrionmental organmisms don't eat weeds. They eat more nutritious plants. And Is only fusion our option? What if we had all of these? We could power the homes and cars of everysingle living person 10 times over and with at least 75% less greenhouse gas emissions.
MYTH: Global warming is just part of a natural cycle. The Arctic has warmed up in the past.
FACT: The global warming we are experiencing is not natural. People are causing it.
People are causing global warming by burning fossil fuels (like oil, coal and natural gas) and cutting down forests. Scientists have shown that these activities are pumping far more CO2 into the atmosphere than was ever released in hundreds of thousands of years. This buildup of CO2 is the biggest cause of global warming. Since 1895, scientists have known that CO2 and other greenhouse gases trap heat and warm the earth. As the warming has intensified over the past three decades, scientific scrutiny has increased along with it. Scientists have considered and ruled out other, natural explanations such as sunlight, volcanic eruptions and cosmic rays. (IPCC 2001)
Though natural amounts of CO2 have varied from 180 to 300 parts per million (ppm), today's CO2 levels are around 380 ppm. That's 25% more than the highest natural levels over the past 650,000 years. Increased CO2 levels have contributed to periods of higher average temperatures throughout that long record. (Boden, Carbon Dioxide Information Analysis Center)
As for previous Arctic warming, it is true that there were stretches of warm periods over the Arctic earlier in the 20th century. The limited records available for that time period indicate that the warmth did not affect as many areas or persist from year to year as much as the current warmth. But that episode, however warm it was, is not relevant to the issue at hand. Why? For one, a brief regional trend does not discount a longer global phenomenon.
We know that the planet has been warming over the past several decades and Arctic ice has been melting persistently. And unlike the earlier periods of Arctic warmth, there is no expectation that the current upward trend in Arctic temperatures will reverse; the rising concentrations of greenhouse gases will prevent that from happening.
The global warming we are experiencing is not natural. People are causing it.
Clearly it can't be 100% natural, if those facts are wrong then hmm maybe half to 3/4 of the world's population are nuts based off of your terms. Even if 400 scientists signed saying it nothing, that don't mean anything compared to the THOUSANDS upon THOUSANDS upon EVEN MORE THOUSANDS of extremely hardcore scientists in the WORLD that are studying this thoroughly.
And yes, alternative fuels WILL lower the effect of global warming by reducing Co2 emissions into the air. I'll agree that we ARE running out of fuel and we WILL need it no matter what eventually, but it does effect every living person. The air is dirtier in cities like New York or Mexico City. Even small towns like Evergreen, Colorado has pollution. And people are breathing that in to their lungs, which ultimatley can make you sick and less immune to disease and illness.
By lower Co2 emissions, less heat is caught from escaping and more is transmitted back down, melting the ice caps and sending powerful heat waves. Hell, even the MOON is moving away from us 3cm a year, which also effects the tides and currents of the oceans, in negative, and positive ways. Look at old and new picutres of antartica and the North pole near Greenland. So much ice has melted because of the heat generated from majority human cause.
