Operation IceBridge (OIB) was a NASA mission to monitor changes in polar ice by utilizing airborne platforms to bridge the observational gap between the ICESat and ICESat-2 satellite missions. The program, which ran from 2009 to 2019, employed various aircraft equipped with advanced instruments to measure ice elevation, thickness, and ...
Some, like Texas, collect information from counties but not from municipalities. Others, like Louisiana, only track deaths of inmates in state custody — a tiny fraction of the jail population. (Jails are short-term holding facilities in which many inmates have not been convicted; our study does not include deaths in prison.)
However, Emmanuel Adu Cole, a prison rights activist, said that the death toll was more than 200. [11] Authorities denied that any inmates successfully escaped, but inmates and prisoners' rights groups said that roll calls found that the number of prisoners in Makala was reduced by nearly 2,000 following the incident.

A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020. As of February 2024, its area is about 3,900 square kilometres (1,500 sq mi), which makes it the current largest iceberg in the world. [2] [3]
March 2017 became the sixth month in a row to set a record for the lowest sea ice extent, according to the National Snow and Ice Data Center (NSIDC).
A JPL analysis published in 2022 found that thinning and crumbling away of Antarctica's ice shelf had reduced its mass by some 12 trillion tons since 1997, double previous estimates.
The ice bridge holding the Wilkins Ice Shelf to the Antarctic coastline and Charcot Island was 40 kilometres (25 mi) long but only 500 metres (1,640 ft) wide at its narrowest point – in 1950 it was 100 kilometres (62 mi) It shattered in April 2009 over an area measuring 20.1 by 2.4 kilometres (12.5 by 1.5 mi). The ice bridge collapsed rapidly ...
