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.

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
