a) The full form of UNFCC with respect to global warming convention is

United Nations Framework Convention on Climate Change.

d) Climatologist measures the global warming rate.

b) Changes in the rainfall takes place due to global warming.

Explanation:

• Carbon dioxide is one of the main greenhouse gases that is responsible for heating of the earth.
• Since pre-industrial times, the amount of carbon dioxide in the atmosphere has increased by around 30%. More heat is trapped in the lower atmosphere as a result of this. The main causes are human activities, industrialisation, and population growth.
• Climate Change Framework Convention of the United Nations (UNFCCC) The ultimate goal of the UNFCCC, which is one of the three Rio Conventions, is to stabilise greenhouse gas concentrations in the atmosphere at a level that prevents dangerous inteference with the climate system.
• Climatologist measures the global warming rate.
• Changes in temperature, as well as the amount of rainfall, result from global warming, causing a slew of issues. These changes in rainfall cause a variety of issues, including floods and droughts.
