Dangerous Hurricane Season To Open Amidst COVID-19

COVID-19 took us by storm but likely won’t be the only storm we will see this year.

The National Oceanic and Atmospheric Administration (NOAA) has just released its Atlantic hurricane season outlook for 2020, forecasting an above-average hurricane season with 13-19 named storms, of which 6-10 could turn into hurricanes. Of these hurricanes, 3-6 could become major. If the outlook projections materialize, 2020 would be the fifth year in a row with above-normal tropical cyclone activity. In addition, the NOAA outlook comes on the heels of the first named Atlantic tropical storm of the season, Arthur, which – for the sixth year in a row – formed before the official start of hurricane season, June 1.

Highlights, Firsts and Worsts of Hurricane Season 2019 and the Future of Hurricanes

Hurricane season ended on November 30, but not before Hurricane Dorian had decimated the Bahamas, taking lives and setting their infrastructure and economy back, potentially for years. On U.S. soil, Hurricane Barry and Tropical Storm Imelda had flooded Texas and the Carolinas, leaving billions in damage.

All told, Hurricane Season 2019 storms were stronger, more rapidly intensifying, slower-moving, and dumped a lot of rain. And this trend may continue if no action is taken to combat climate change. Read more >

Hurricane Season 2019: Global Warming, Forecasts, and Probabilities

According to NASA, 2018 was the 4th warmest year in a continued warming trend since record keeping began in the 1880’s, with temperatures 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean. And with it, a string of five consecutive years have been recorded as the five warmest on record. Is climate change having an effect on hurricane season, or on hurricanes themselves? Hurricane season starts on June 1st. Let’s take a look at the latest forecasts and science. Read more >

North Carolina Army National Guardsmen and local emergency services assist with evacuation efforts in Fayetteville, N.C., Oct. 08, 2016. Heavy rains caused by Hurricane Matthew led to flooding as high as five feet in some areas.

What a Difference 0.5°C Makes! Or, How a Seemingly Small Amount of Global Warming can Lead to a lot More Rain

The soon-to-be released Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5°C (IPCC 1.5) assesses, among other things, the impacts that could be avoided if global warming is kept to 1.5°C instead of 2°C, and the ways we can limit some of the worst impacts of climate change and adapt to the ones that are unavoidable. Let us pause and think for a moment about this business of 1.5°C and 2°C, because 0.5°C just seems like such a small difference. Why so much discussion about this seemingly small difference in global temperature? Read more >
