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 ...

Countries must follow strict carbon emission regulations in their territorial seas or exclusive economic zones to meet their commitments under the Paris Agreement on climate change. However, because the agreement doesn't hold signatories directly accountable for reducing carbon emissions on the high seas, no policies have been proposed to tackle shipping's carbon footprint in these areas.   Source: NOAA Ocean Exploration.   The high seas cover more than two-thirds of the world's oceans. Shipping activities that rely on carbon-based fuels on the high seas could become a potential obstacle to global efforts toward reducing carbon emissions and achieving sustainability goals.   Source: Juan L Suarez de Vivero, Department of Human Geography, University of Seville. High-seas shipping is responsible for almost one-third of all global shipping emissions, which exceeds the annual greenhouse gas emission outputs of many mid-sized European countries. Researchers estimate that emiss...

Last year, people in India suffered devastating #heatwaves between March and April ( #summer ), with five times increased #heatwave days and an 8°C higher temperature than the average #temperature between March and April. Further, in the last few months of this year, due to the lack of #winterstorm in the #mediterranean , there may be possibilities that Western Disturbance (WD) shall be ineffective in disorganising the recently growing #warm regions. The WD is a tropical cyclone that originated in the #mediterraneansea and moves towards #india up to south-eastern #nepal and northern #bangladesh . The high-pressure system displayed over regions like #russia , #ukraine , and neighboring countries causes cold air influx from the Polar Regions towards an area of relatively warmer air with significant moisture. Consequently, an extratropical depression that moves eastward is formed in the Mediterranean Sea, resulting in the pressure change from cold to warm air. This creates ideal c...
