Question

Why should we have worried about global warming? Suggest four ways of reducing air pollution​

Answer 1

Answer:

we should have worried about Global Warming in the following ways-

Measurements of global air temperatures show a long-term rise over recent decades, but the rise isn’t steady. Like the stock market, it jumps up and down on shorter time scales. There was a spike in 1998, for example. If you measure global warming from that year onward, you get a distorted picture the overall trend, said Penn State climatologist Richard Alley. The trend over decades is what we should focus on.

What’s even more worrisome, he explained, is that air temperatures only give part of the picture. The real concern with the buildup of greenhouse gases is that “we’re getting more energy from the sun than we’re sending back into space,” he said. That energy, he said, is not only warming the atmosphere, it’s also melting ice and warming the oceans.

the four ways of reducing air pollution are-

Riding a bike or walking instead of driving.

Taking a bus or carpooling.

Buying a car that has greater fuel efficiency.

Turning off lights and appliances when they are not in use.

riding a bike or walking instead of driving.

taking a bus or carpooling.

buying a car that has greater fuel efficiency.

buying fewer things that are manufactured using fossil fuel.
