Glacier’s Rapid Disintegration Upends Sea-Level Rise Forecasts

A new study led by the University of Colorado Boulder and published in Nature Geoscience details the unprecedented 2023 retreat of Antarctica’s Hektoria Glacier, comparable in size to the city of Philadelphia. Using seismic data, satellites and remote sensors, the research team surveyed the glacier, capturing its topography and retreat at different time intervals. They noted that the glacier retreated five miles in just two months, 10 times faster than any previous record. The scientists believe the glacier floated above the ice plain, exposing it to warm ocean water and tidal forces, which caused large chunks of ice to break off.

This accelerated retreat is reshaping sea-level rise predictions. The study highlights the swift destabilization of grounded glaciers, indicating that current models likely underestimate the pace of Antarctic ice loss and the resulting coastal flooding from sea level rise. This is especially concerning for larger ice sheets like Thwaites, which rivals the size of Great Britain.

Tick Tackler

Spring officially sprung on March 21. We have turned our clocks ahead. We are looking forward to warm winds, sunny skies and the smell of fresh cut grass. The daffodils and tulips have recently bloomed and we are just starting with the yard work that comes with the warmer weather.  Sadly, another season has started ramping up.  Tick season.

•             The best form of protection is prevention. Educating oneself about tick activity and how our behaviors overlap with tick habitats is the first step.

•             According to the NJ DOH, in 2022 Hunterdon County led the state with a Lyme disease incidence rate of 426 cases per 100,000 people. The fact is ticks spend approximately 90% of their lives not on a host but aggressively searching for one, molting to their next stage or over-wintering. This is why a tick remediation program should be implemented on school grounds where NJ DOH deems high risk for tick exposure and subsequent attachment to human hosts.

•             Governor Murphy has signed a bill that mandates tick education in NJ public schools. See this for the details.  Tick education must now be incorporated into K-12 school curriculum. See link:

•             May is a great month to remind the public that tick activity is in full swing. In New Jersey, there are many tickborne diseases that affect residents, including Anaplasmosis, Babesiosis, Ehrlichiosis, Lyme disease, Powassan, and Spotted Fever Group Rickettsiosis.

•             For years, the focus has mainly been about protecting ourselves from Lyme disease. But other tick-borne diseases are on the rise in Central Jersey. An increase of incidence of Babesia and Anaplasma are sidelining people too. These two pathogens are scary because they effect our blood cells. Babesia affects the red blood cells and Anaplasma effects the white blood cells.

•             Ticks can be infected with more than one pathogen. When you contract Lyme it is possible to contract more than just that one disease. This is called a co-infection. It is super important to pay attention to your symptoms. See link.
