Study on Countries’ commitment on Climate Change

Study on Countries’ commitment to Climate Change

Context: This topic is important for UPSE GS Paper 3.

The findings, while optimistic, come amidst the deliberations underway at Glasgow.

How effective are climate change pledges made by countries in containing global warming?

A study published Friday in the journal Science finds that the latest Nationally Determined Contributions by 120 countries, as of September 30, improve the odds of global temperature rise staying below 2°C by 34% and below 1.5°C by 1.5%.

By way of comparison, the 2015 pledges made by countries at the Paris Agreement promised only an 8% chance of temperatures staying below 2°C, and zero—or no chance—at 1.5°C.

Reaching net zero

  • If countries were to follow a more ambitious path beyond 2030, those probabilities rose to 60% and 11% respectively.
  • The findings while optimistic come amidst the deliberations underway at Glasgow where the greatest global effort is underway to have countries sign on to an agreement to keep temperatures below 1.5°C and, to this end, have most major economies pledge to reach net zero by mid-century.
  • Net zero is when a country's emissions are offset by having an equivalent amount removed from the atmosphere for zero emissions in balance. While countries such as the United States, the United Kingdom and the European Union have committed to a 2050 timeline, China—the world's largest polluter—has indicated a 2060 timeline and India—the third largest—a 2070 timeline.
  • Only 12 countries have enshrined this commitment in law. These are Germany, Sweden, Japan, United Kingdom, France, Canada, South Korea, Spain, Denmark, New Zealand, Hungary, and Luxembourg.
  • Climate change has already caused global temperatures to rise about 1.2°C above pre-industrial levels.

Way Forward

  • In the past, it has taken thousands of years for the temperature to rise by a few degrees, and dramatic changes, from unpredictable swings in India's monsoon to accelerated heating of the oceans, are already occurring as a result of a 1.2°C increase.
  • Scientists are calling for climate change to be limited as much as possible to avoid triggering cascading and compounding “tipping points” that could limit our ability to contain global heating.
