Is glabal warming a problem in our country

Get answer In Explanation

Explanation:   The cost and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate, the more negative the consequences will become. Global warming will probably make life harder, not easier, for most people. This is mainly because we have already built enormous infrastructure based on the climate we now have.

People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level, more erratic rainfall, and droughts.

The crops, natural vegetation, and domesticated and wild animals (including seafood) that sustain people in a given area may be unable to adapt to local or regional changes in climate. The ranges of diseases and insect pests that are limited by temperature may expand, if other environmental conditions are also favorable.

The problems seem especially obvious in cases where current societal trends appear to be on a “collision course” with predictions of global warming’s impacts:

at the same time that sea levels are rising, human population continues to grow most rapidly in flood-vulnerable, low-lying coastal zones;

places where famine and food insecurity are greatest in today’s world are not places where milder winters will boost crop or vegetation productivity, but instead, are places where rainfall will probably become less reliable, and crop productivity is expected to fall;

the countries most vulnerable to global warming’s most serious side effects are among the poorest and least able to pay for the medical and social services and technological solutions that will be needed to adapt to climate change.

In its summary report on the impacts of climate change, the Intergovernmental Panel on Climate Change stated, “Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.”

Concern about climate change is much less pervasive in the United States, China and Russia than among other leading nations. Just 44% in the U.S. and Russia, and even fewer in China (30%), consider global warming to be a very serious problem. By comparison, 68% in France, 65% in Japan, 61% in Spain and 60% in Germany say that is the case.

Americans’ views of global warming divide along ideological lines — liberals are more than twice as likely as conservatives to say global warming is a very serious problem (66% vs. 30%). Surveys from 2008 and 2009 suggest that an ideological divide is also evident in Britain, where 66% of those on the political left rate global warming as very serious, compared with 42% of those on the right. A smaller ideological split exists in Germany, France and Spain.

While there is agreement around the world that climate change is a serious problem, there is much less international consensus as to which country is most trusted to do the right thing on this issue. However, expectations for President Barack Obama’s approach to climate change are high. Majorities or pluralities in 21 of the 25 countries surveyed believe Obama will “get the U.S. to take significant measures to control global climate change.” Expectations are especially high in Western Europe.
