Global Warming - Current Affairs Questions and Answers

1)   As a result of global warming, Himalayas will have to contend with flooding while Andes will have less water and _________, according to scientists.

a. Desertification
b. Long dry spells
c. Heavy rains
d. None of the above
Answer  Explanation 

ANSWER: Long dry spells

Explanation:
Different regions of the planet will react to global warming differently according to scientists. Researchers have shown that people in the Himalayas will have to contend with flooding while those in Andes will have longer dry spells and less water.

  • Swiss researchers measured data and climate models to examine water balances in mountain ranges of upper Langtang valley in Nepal and Juncal region of central Andes.
  • While in the upper Langtang valley, water discharge will increase in the first half of this century by as much as 70 percent, Juncal region will become drier in the future.


2)   Scientists have turned which pollutant gas into stone to avert global warming?

a. NO2
b. CO
c. CO2
d. SO2
Answer  Explanation 

ANSWER: CO2

Explanation:
Scientists have turned carbon dioxide into stone in a matter of months by pumping it deep underground, offering a revolutionary new way of storing the greenhouse gas to tackle climate change.

  • The pioneering experiment in Iceland mixed CO2 emissions with water and pumped it hundreds of meters (feet) underground into volcanic basalt rock — where it rapidly turned into a solid.
  • Carbon dioxide is a key factor in global warming
  • CarbFix project at Iceland's Hellisheidi plant — the world's largest geothermal facility, which powers Reykjavik — sought to solidify the CO2 and succeeded in doing so.


3)   Negotiators from how many countries delivered a blueprint on 5th December 2015 for saving mankind from historic global warming?

a. 193
b. 195
c. 197
d. 200
Answer  Explanation 

ANSWER: 195

Explanation:
195 nations delivered a blueprint for a pact for saving mankind from global warming raising hopes of a historic agreement in Paris. Planned deal will break the dependence of the world on fossil fuel energy. Around 50 personalities indicated that they would fight climate change including US actor Sean Penn and Internet tycoon from China, Jack Ma.


4)   Global warming could change the shape of the planet due to melting glaciers which____________.

a. Increase the sea level
b. Erode the land
c. Dig deeper valleys and shed sediment into the ocean
d. All of the above
Answer  Explanation 

ANSWER: All of the above

Explanation:
Melting glaciers continue to erode the land causing climate change to impact the shape of the planet. Antarctica is warming up and glaciers are going to move faster and become more erosive, adding to the impact of climate change in the polar regions. Faster moving glaciers are responsible for depositing more sediment in downstream basins and continental shelves, creating an impact on fisheries, dams and access to provide potable freshwater in hilly communities. Researchers also found after comparing the glaciers in Patagonia and Antarctic Peninsula, glaciers in warmer Patagonia melted faster causing a greater degree of erosion. Scientists found that glaciers erode 100 to 1000 times faster in Patagonia than Antarctica.


5)   Man made global warming has caused the following years to be the warmest ever recorded as per the British Met Office:

a. 2012, 2013, 2014
b. 2013, 3014, 2015
c. 2014, 2015, 2016
d. 2000, 2001, 2002
Answer  Explanation 

ANSWER: 2014, 2015, 2016

Explanation:
It looks likely that globally 2014, 2015 and 2016 will all be amongst the very warmest years ever recorded, National Centre for Atmospheric Science, which contributed to the report, announced. The rate at which global temperatures are increasing is also on track to pick up in the coming years, ending a period of more than a decade in which the pace of warming worldwide had appeared to slow down.

An El Nino weather pattern centred in the tropical Pacific Ocean is "well underway", the report says and this is likely to result in dry conditions in parts of Asia and Australia, as well as southern and sub-Saharan North Africa. By contrast, the southwestern US has a strong chance of seeing greater than-average rainfall. El Ninos also affect tropical storms, making them less likely in the North Atlantic and more intense in the West Pacific.
