We're a collective of individuals upset with the way social media has been traditionally governed. A severe lack of moderation has led to major platforms like Facebook to turn into political machinery focused on disinformation campaigns as a way to make profit off of users. Websites with ineffective moderation allow hate speech to proliferate and contribute to the erosion of minority rights and safe spaces. Our goal with Beehaw is to demonstrate and promote a healthier environment.

"Our findings indicate that the spatial risk of TC-induced damage to OSW turbines along the US Atlantic and Gulf Coast regions is broadly expected to increase, with strong intermodel agreement on the sign of change (i.e., increase or decrease) in all regions assessed. Detailed regional estimates and their associated uncertainties are outlined in Table 1. Significant increases in yielding risk are expected for the Gulf Coast and Florida peninsula resulting from 20- and 50-year storms (Fig. 1), with the average risk of turbine yielding estimated to increase by nearly 40% for a 20-year storm (Fig. 1c) and 27% for a 50-year storm (Fig. 1f). The Atlantic Coast exhibits similar changes, with projected increases in turbine yielding risk of about 35% for 20-year TCs and 31% for 50-year TCs.

Buckling, being a more acute damage state than yielding, requires higher wind speeds to surpass the structural limit. Historically, the probability that 20- or 50-year storms would induce turbine buckling has been below 10% across all regions assessed. However, under future climate change, this probability is estimated to rise to as high as 57% (Table 1), with the strongest increases and future risk expected for the Southeast and Gulf Coast regions (Fig. 2). For the Gulf Coast and Florida, buckling risk from a 20-year storm is projected to increase from nearly 0% to almost 18% (Fig. 2c). This increase is far more severe when considering a 50-year storm, with the buckling risk in this region expected to grow by almost a factor of eight. Along the Atlantic Coast, the likelihood of TC-induced turbine buckling is projected to rise as well, with anticipated increases in risk of about 9% for a 20-year TC and 34% for a 50-year TC. For both turbine yielding and buckling, the likelihood of damage is markedly higher for the Southeast than the Northeast, differing by almost 12% historically and by over 24% in a simulated future climate (Table 1)."
