Over the past 100 years, the estimated rise of global sea level is by 10 to 25 cms or more. This is attributed to which of the following?

• A. Thermal contraction of ocean water

• B. Melting of glaciers and small ice caps

• C. Thinning of the Greenland ice sheet

• D. Changes in terrestrial water storage

Choose the correct answer from the options given below:

Correct option is C

B,C and D only

The estimated rise in global sea level by 10 to 25 cm or more over the past 100 years is attributed to:
Melting of glaciers and small ice caps.
Thinning of the Greenland ice sheet.
Changes in terrestrial water storage.
Therefore, the correct answer is 3. B, C and D only/केवल B, C और D.
Additional Information:
Global mean sea level has risen by an average of 3.4 mm per year since 1993, with a total increase of 10.3 cm over the past 30 years.
Thermal expansion of ocean water also contributes to sea level rise.
The rate of sea level rise has accelerated in recent decades.
Melting glaciers and ice sheets are major contributors to sea level rise.
The rise in global mean sea level has increased by 105%, from a trend of 2.1 mm/year over 1993–2003 to a trend of 4.3 mm/year over 2013–2023.
Over the past 100 years, global temperatures have risen about 1 degree C (1.8 degrees F), with sea level response totaling about 160 to 210 mm (6 to 8 inches).
Scientists estimate that at least 3 feet of sea level rise is inevitable, but it is uncertain whether this will occur within a century or longer.
The IPCC projects that with very deep cuts in emissions, sea level rise could reach between 30 cm (1 ft) and 1.0 m (3 1/3 ft) by 2100, relative to present, and approximately 60 cm (2 ft) to 130 cm (4 1/2 ft) from the 19th century.
