Climate Tipping Points: Approaching Thresholds to Cause Catastrophic Changes in Climate System

-

The continuously rising temperatures and increasing sea levels are the utmost concern of the 21st century. The temperature on planet Earth is getting warmer day by day. The industrial revolution has played the major causes behind it by increasing emissions of greenhouse gases globally. Researchers around the world are deeply concerned about the climate tipping points as they may cause catastrophic changes in the earth’s climate system.

According to the Intergovernmental Panel on Climate Change (IPCC), Tipping Points of Climate Change are the critical thresholds in the ecosystem which when overstepped cause notable changes where the climate system may not return to its prior state. The Global Tipping Points report highlighted 5 crucial tipping points that have crossed the risk margin. By 2030 three more are expected to cross if the Earth gets warmer than 1.5 C. Tipping points have the potential to trigger harmful domino effects, impacting the entire biosphere and manifestation of staple crops, financial loss, and political fragility.

Some of the crucial tipping points that are at risk are primarily in Greenland and the West Antarctic, where the big ice sheets collapsed, leading to a notable increase in the sea level affecting the mass population residing in the low-lying areas and coastal areas. It will force them to be displaced to a safer place, further causing economic and livelihood losses.

As the Earth is getting warmer, coral reefs present in the warm waters are dying due to bleaching phenomena in the water's higher temperature causing loss of coastal security, ecosystem, and fisheries. Increased thawing of Permafrost causes a great loss to the mass and will be unable to support vegetation and soil above it posing a serious threat to the infrastructure sector worldwide.

The crumbling of the North Atlantic Oceanic Current has the power to impact climate patterns globally. As the water on the Earth gets warmer than 1.5 C the coastal biosphere like Seagrass Meadows and Mangroves will collapse. Thus, to sustain humanity on Earth, the world has to unite and come up with fruitful climate-saving policies in the future to challenge these catastrophic climate changes.

The world is gearing up to deal with the evil impacts of climate change as these are becoming more visible and hampering developments across sectors. Thus, India is also preparing for its fight against climate change by securing its first Green Climate Fund (GCF) Project named the Avaana Sustainability Fund (ASF) . The Small Industries Development Bank of India (SIDBI) an Accredited Entity (AE) of GCF has securely achieved its maiden green climate project in March 2024 at Kigali, Rwanda. Source: https://www.entrepreneur.com/en-in/news-and-trends/sidbi-secures-first-green-climate-fund-gcf-project/470953 This project worth a market value of US$ 120 million includes GCF investment of US$ 24.5 million . This GCF share of investment is provided by the South Korean division of GCF which is considered the world’s largest climate fund . The ASF project will invest in early-stage companies that have mastered their prototypes, business plans, and service models concerning climate change. Under...

  Mars is on the priority list of human space exploration where the traces of life's existence may be achieved. NASA's CHAPEA (Crew Health and Performance Exploration Analog) project i.e. a Mars simulation mission is thus crucial and is aiming to improve efficiency and ensure the safety of astronauts during its future manned missions to Mars. Source: https://www.nasa.gov/humans-in-space/humans-to-mars/#preparing Recently, on 6 th July 2024, the four volunteers completed their first MARS simulation mission under this project at Jhonson Space Center, Houston which was started on 25 th June 2023 . The crew at Mars Dune Alpha Habitat which is a 1,700-square-foot, 3D-printed structure consisted of individuals selected to simulate the roles and diversity expected on a real Mars mission. NASA is preparing for its manned mission to Mars in 2030 and before that, it has planned to execute two more such simulation missions in 2025 and 2027 respectively under this project. The pr...
