Sea level rise is a complex response to Earth’s shifting climate. Because climate change is largely dependent on greenhouse gases, from both natural and human activities, it is challenging to accurately predict changes, including the timing and magnitude of sea level rise.

The main physical effects of sea level rise include:

• Low-lying coastal areas may experience more frequent flooding (temporary wetting) or inundation (permanent wetting). As riverine and coastal waters come together at river mouths, coastal lagoons, and estuaries, higher water levels at the coast may cause water to back up and increase upstream flooding.
• Many shorelines have sea walls, jetties, and other artificial defenses to protect roads, buildings, and other vital coastal resources. In these areas, sea-level rise increases erosion of stranded beaches, wetlands, and engineered structures
• Sea-level rise can mean that saltwater intrudes into groundwater drinking supplies, contaminates irrigation supplies, or overruns agricultural fields. Low-lying, gently sloping coastal areas are particularly vulnerable to contamination of freshwater supplies.

Protected Areas in India comprise National Parks, Sanctuaries, Conservation / Community Reserves and Tiger Reserves. Protected Area (PA) has been defined in the Wildlife (Protection) Act, 1972.

The Wild Life (Protection) Act, 1972 was a major step towards wildlife conservation. The Act classified animals into different schedules based on the need for protection, and hunting of these species was outlawed and penalties were prescribed in case of violations. This legislation played a major role in protecting India’s rich wildlife.

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind.

Hydrogen generated entirely from renewable power sources is called green hydrogen. In this process, electricity generated from renewable energy is used to split water into hydrogen and oxygen.

Green Hydrogen as energy source is a clean burning molecule which can decarbonise a range of sectors including iron and steel, chemicals and transportation.
