By: Subbu Upputuri, Dr. Chandu Visweswariah, Dr. Thomas N. Theis, Dr. Anjali Sauthoff Executive Summary The transition from fossil fuel vehicles to electric alternatives is a critical step towards reducing greenhouse gas (GHG) emissions and combating climate change. However, the localized impacts on air quality, specifically fine particulate matter (PM2.5) emissions, are more nuanced. In some electricity zones of the…
By: Chandu Visweswariah In India, a billion people went to the polls over a 6-week period ending on June 1, 2024. Meanwhile, a scorching heat wave raised temperatures in New Delhi, the capital city, to an unbearable 120oF (49oC). Despite this juxtaposition of intense political and climate activity, climate change was not a plank in the platform of any of…

By: Chandu Visweswariah Dear human race, Congratulations on centuries of progress and triumph (albeit bumpy at times). Your intellectual, artistic, medical and scientific progress in the last few centuries has been impressive. You have also made incremental progress on injustice, bigotry, discrimination and exploitation of all kinds, be it slavery, racism, colonialism or elitism. Failure However, it pains me to…
By: Chandu Visweswariah Summary With each passing year of under-achievement in reducing greenhouse gas (GHG) emissions, our planet’s carbon budget is dwindling. To avoid truly catastrophic and irreversible damage from climate change, this blog argues that the world now has to achieve net zero by 2034, if not sooner. What is a Carbon Budget? A carbon budget is an amount…
By: Chandu Visweswariah I’ve been asked by multiple friends and relatives what it’s like to drive an EV in frigid weather. I usually reply that the combination of a heavier car, low center of gravity, high torque at slow speeds, and four-wheel drive is an unbeatable combination in snowy and icy conditions. In fact, given that our driveway is steep,…

But now it is already time to reinvent that same engineering marvel…
By: Chandu Visweswariah The two biggest sources of carbon emissions in our part of the country in the Northeast are transportation and building heating. Most homes and buildings are heated with a fossil fuel furnace, burning fuel oil, gas or propane to produce heat. To decarbonize rapidly, we urgently need all new construction to incorporate heat pumps, and all existing…
By: Chandu Visweswariah August 16 was the one-year anniversary of the Inflation Reduction Act (IRA), the most significant piece of climate legislation ever passed anywhere in the world. And New York State just announced incentives and subsidies from the Environmental Bond Act (EBA) that all of us helped to pass in November 2022. This financial assistance is additive to Federal…
By: Chandu Visweswariah A timely solution to our climate crisis can only be achieved by a rapid global phase-out of fossil fuels. Therefore, we urgently need international agreement on a timetable. Mankind has historically dealt with dangerous poisons like leaded gasoline, freon, carcinogens like PCBs, asbestos, and now it is time to firmly and permanently close the spigot on fossil…
