How we discovered SEA LEVEL RISE 1948-1990
On the history how humans discovered knowledge related to sea level rise, based on motion pictures, with the scope on Antarctica. Footage spanning from 1948 up to 1990.
Global Warming Explained in 1956
Published in 1956 for American television by the California Academy of Sciences. Bernard Hubbard explains how glaciers retreat, he mentions how since 1857 glaciers recede worldwide. Hubbard also explains the ice albedo effect, and how glaciers disintegrate. This program is devoted to glaciers, and also includes a promo for the Academy of Sciences. SPEAKER Bernard…

Extinction Events in Earth History and Today
Flood Basalts and Mass Extinctions – refine ancient hyperthermals as analogs for anthropogenic climate change. Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1] Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…
The Current State of Arctic PERMAFROST THAW
Soil layers of permafrost that scientists expected to remain frozen for at least 70 more years have already begun thawing. NOTES In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and…
The Mystery of the Antarctic Sea Ice Puzzle, Sea ice Plummeting Suddenly
The amount of ice circling Antarctica is suddenly plunging from a record high to record lows, baffling scientists. A new NASA study by sea ice expert Claire L. Parkinson reveals recent trends in Antarctica’s sea ice extent. CREDITS A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the…
Video: Enhanced Seismic Activity Observed in Alaska Due To Climate Change
With news breaking that Alaska just had its warmest March to May on record with a statewide average temperature of 32.6°F, 8.6°F above the long-term average – the previous warmest spring in Alaska was in 2016, one must ask how this performs in relation to seismicity. Read the study excerpts of, Enhanced Seismic Activity Observed in Alaska Due…
