Solution

The correct option is B Because temperature will rise faster
Global warming is the increase in the temperature of Earth due to the increased concentration of greenhouse gases in the atmosphere. Temperature change due to global warming is faster than the temperature change due to natural climate fluctuations. This has resulted in melting of ice glaciers which will lead to rising in sea level and also the amount of freshwater will decline. Abnormal increase in temperature due to global warming has resulted in the extinction of many plant and animal species because of habitat loss and extreme climatic conditions.
So, the correct answer is option A.

Q. Assertion :Global warming refers to an increase in the average temperature near the Earth's surface. Reason: Climate change refers to the broader set of changes that go along with global warming, including changes in weather patterns, the oceans, ice and snow, and ecosystems.

Q. Although almost all climate scientists agree that the Earth is gradually warming, they have long been of two minds about the process of rapid climate shifts within larger periods of change. Some have speculated that the process works like a giant oven freezer, warming or cooling the whole planet at the same time. Others think that shifts occur on opposing schedules in the Northern and Southern Hemispheres, like exaggerated seasons. Recent research in Germany examining climate patterns in the Southern Hemisphere at the end of the last Ice Age strengthens the idea that warming and cooling occurs at alternate times in the two hemispheres. A more definitive answer to this debate will allow scientists to better predict when and how quickly the next climate shift will happen

Q. Global warming and climate change are two different concepts.

Q. Read the following passage and answer the questions that follow:

A new analysis has determined that the threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping green-house gases by 70% this century. The analysis was done by scientists at the National Centre for Atmospheric Research (NCAR). While global temperatures would rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea-level rise, could be partially avoided.
“This research indicates that we can no longer avoid significant warming during this century,” said NCAR scientist Warren Washington, the study paper’s lead author. “But, if the world were to implement this level of emission cuts, we could stabilise the threat of climate change”, he added.
Average global temperatures have warmed by close to 1°C since the pre-industrial era. Much of the warming is due to human-produced emissions of greenhouse gases, predominantly carbon dioxide. This heat-trapping gas has increased from a pre-industrial level of about 284 parts per million (ppm) in the atmosphere to more than 380 ppm today. With research showing that additional warming of about 1°C may be the threshold for dangerous climate change, the European Union has called for dramatic cuts in emissions of carbon dioxide and other greenhouse gases.
To examine the impact of such cuts on the world’s climate, Washington and his colleagues ran a series of global studies with the NCAR-based Community Climate System Model (CCSM). They assumed that carbon dioxide levels could be held to 450 ppm at the end of this century.
In contrast, emissions are now on track to reach about 750 ppm by 2100 if unchecked. The team’s results showed that if carbon dioxide were held to 450 ppm, global temperatures would increase by 0.6°C above current readings by the end of the century. In contrast, the study showed that temperatures would rise by almost four times that amount, to 2.2°C above current readings, if emissions were allowed to continue on their present course. Holding carbon dioxide levels to 450 ppm would have other impacts, according to the climate modeling study.
Sea-level rise due to thermal expansion as water temperatures warmed would be 14 cm (about 5.5 inches) instead of 22 cm (8.7 inches). Also, Arctic ice in the summertime would shrink by about a quarter in volume and stabilize by 2100, as opposed to shrinking at least three-quarters and continuing to melt, and Arctic warming would be reduced by almost half.

What does the scientist Warren Washington mean when he says “we could stablise the threat of climate change”?

Q. The World Wildlife Fund has declared that global warming, a phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.
