Climate Change Feedback Loop

During the discussion of Terraforming Mars, the "climate change feedback loop" came into the picture. In simple words, the climate change feedback loops are cyclical contraption chain reactions, where one change triggers further changes, and the complete process keeps repeating itself. There are two types of feedback loops, positive and negative. The negative feedback loops tend to dampen or reduce the changes. The system tends to hold some equilibrium state, making it more stable. However, the positive feedback loops enhance or amplify changes. The system tends to move away from its equilibrium state, making it more unstable.

The point of concern is that some scientists believe that the carbonation of soil and sea, along with the photosynthesis done by plants and trees, is part of a negative feedback loop. However, in the long run, the same becomes a part of a positive feedback loop.

Global warming melting polar ice caps leads to disturbance of ocean currents by salinity difference generated by the infusion of cold fresh water. These ocean currents responsible for the temperature regulation of Earth generate heat/cold waves. These Heat/cold waves increase the unpredictability of the weather, leading to crop damage by drought, heavy rainfall, storms, and snowfalls. The damaged crop/forest will ferment and release the more potent greenhouse gas, Methane, into the atmosphere, further increasing the global average temperature.

Moreover, the said climate change feedback loop is driving wildfires. The increase in the temperature increases the probability of wildfire. These wildfires directly pump the stored carbon dioxide in the plants/trees into the atmosphere, increasing the global average temperature.

After Heat Wave - Still No Sustainability

After Heat Wave - Still No Sustainability After recent significant heat waves and their consequent outcomes in the weather trends, there is still a need for the adoption of sustainable measures. This post will focus on the effects of human activities on the energy cycle of the earth. The most immediate fix is the best option but for the short term only. Now, the time has come to achieve the long-term goals by imposing stringent policies. Source: University of Bristol Recent studies estimate that the world will add about 1 billion Air Conditioners (ACs) by the end of 2030, and projected to nearly double before 2040. This expansion of AC coverage threatens to worsen the crisis it's responding to, as most ACs still use refrigerants like Hydro Fluoro Carbons (HFCs), which can have 1,000 times the warming potency of Carbon Dioxide (CO2). Further, various studies estimate that if the world fails to lower, the dependence on HFCs could result in half a degree Celsius of warming by the end

Environmental Economics

Environmental economics is a branch of #economics that focuses on the relationship between the economy and the #environment . It seeks to understand and analyse how human activities impact the natural environment and how the environment, in turn, affects economic systems. Environmental economics aims to provide insights and tools for addressing environmental challenges and achieving #sustainabledevelopment . In this blog post, we will focus on the working of sustainable #green economics with amendments emphasising the overall development of the world. In 2000, #climatechange had not gained the attention and urgency as today. In 2023, environmental economics is focused on understanding and addressing the economic implications of climate change, including the costs of mitigation and adaptation measures, #carboncredits , and the valuation of ecosystem services affected by climate change. After so many initiatives taken by various organisations, there is still a gap in the #emissionstr
