Study the following statements about Greenhouse gases effect. a. Our planet was heating at the rate of 1°C per 100 years, till 1970. b. Since last 20 years, the planet has been warming at the rate of 10°C per 100 years. c. Most of the glaciers in different parts of the world are retreating. d. Frequency and effect of El Nino is increasing. Which of the above statements is/are correct ? Correct Answer Only a,c and d are correct

The correct answer is Only a,c and d are correct.

Key Points

  • As per the IPCC report,
  • Our planet was heating at the rate of 1°C per 100 years, till 1970.
  • Since 1970 the global average temperature has been rising at a rate of 1.7°C per 100 years.
  • Most of the glaciers in different parts of the world are retreating.
  • The frequency and effect of El Nino are increasing.
  • Hence statement b is not correct and Only a,c, and d are correct.

Important Points

  • Greenhouse effect
    • The greenhouse effect is a natural process that warms the Earth's atmosphere. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected in space and the rest is absorbed and re-radiated by the greenhouse gases.
  • IPCC
    • The Intergovernmental Panel on Climate Change is an intergovernmental body of the United Nations that is dedicated to providing the world with an objective, scientific information.
    • IPCC releases reports on climate change and Land, Global warming, Ocean and Cryosphere, etc. 
    • Founded: 1988.
    • Headquarters location: Geneva, Switzerland.
    • Parent organizations: World Meteorological Organization, United Nations Environment Programme.

Deforestation also increases carbon dioxide emissions. R. Greenhouse gases include carbon dioxide, CFCs, etc. S. The increasing use of fossil fuels is a major cause of carbon dioxide emission. 6. Carbon dioxide traps heat and causes the greenhouse effect.
If the 'Mercury planet' is called 'Uranus planet', 'Uranus planet' is called 'Jupiter planet', 'Jupiter planet' is called 'Mars planet', 'Mars planet' is called 'Earth planet', 'Earth planet' is called 'Saturn planet', 'Saturn planet' is called 'Venus planet', and 'Venus planet' is called 'Pluto planet', then on which planet do we live?
Rearrange the given 5 sentences A, B, C, D and E in proper sequence to form a meaningful paragraph and mark the correct sequence from the given options as your answer. It is caused due to the greenhouse effect of increased level of green house gases such as carbon dioxide, CFCs, etc. There are various types of pollutants also which involved in increasing the atmospheric temperature of the earth. Water vapor is also a significant greenhouse gas which is not directly produced by humankind but involve in global warming hugely. Global warming is a gradual increase in the temperature of the earth surface and atmosphere all around the world. Increasing use of fossil fuels by the people and deforestation is increasing carbon dioxide emissions which trap heat and cause greenhouse effect.
In the question given below,three paragraphs are given, which arejumbled. Find the correct sequence ofthese paragraphs so that they form ameaningful passage.
A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.

The question below consists of a set of labelled sentences in which first and the last sentence is given. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. S1- Climatic changes have become more prominent now because of global warming which is a global concern. P- Such gases never let sun rays to go back to the atmosphere, however, trap heat from them.  Q- The release of various greenhouse gases in the atmosphere by many natural means and human activities causes an increase in atmospheric temperature because such gases have a capability to absorb all the heat of environment from the sun, burning coal, etc. R- Both are hot issues of the current time and it is the time to analyse causes and prevention methods to prevent global warming.  S- Fossil fuels burning release more carbon dioxide which is increasing day by day because of deforestation.  S6- Plants are the main source to utilize carbon dioxide as a food, however, we are disturbing the natural cycle by cutting more plants.
