India has questioned the rush at the United Nations (UN) to declare climate change an international security issue, potentially giving the Security Council the right to take action on it, and pointed out the pitfalls in the approach. According to India, A “mere decision of the Council” to take over enforcement of climate change action would disrupt the Paris Agreement and multilateral efforts to find solutions. Climate change is a global threat to security in the 21st century. We must act now to limit future risks to the planet we share and the peace we seek.

The periodic modification of Earth’s climate brought about due to the changes in the atmosphere as well as the interactions between the atmosphere and various other geological, chemical, biological and geographical factors within the Earth’s system is called Climate change.

Factors Affecting Climate Change

Natural Factors – affect the climate over a period of thousands to millions of years.Such as – 

  1. Continental Drift – have formed millions of years ago when the landmass began to drift apart due to plate displacement. This impacts climate change due to the change in the landmass’s physical features and position and the change in water bodies’ position like the change in the follow of ocean currents and winds.
  2. Volcanism – Volcanic eruption emits gasses and dust particles that last for a longer period causing a partial block of the Sun rays thus leading to cooling of weathers and influencing weather patterns.
  3. Changes in Earth’s Orbit – A slight change in the Earth’s orbit has an impact on the sunlight’s seasonal distribution reaching earth’s surface across the world. There are three types of orbital variations – variations in Earth’s eccentricity, variations in the tilt angle of the Earth’s axis of rotation and precession of Earth’s axis. These together can cause Milankovitch cycles, which have a huge impact on climate and are well-known for their connection to the glacial and interglacial periods.
