Declining Butterfly Populations Linked to Fall Warming Trends

( University of Arizona ) Western butterfly populations are declining at an estimated rate of 1.6% per year, according to a new report to be published this week in Science. The report looks at more than 450 butterfly species, including the western monarch, whose latest population count revealed a 99.9% decline since the 1980s.

Species’ Thermal Tolerance is Linked to Current Climate Where They Live

Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.

Satellite Data can Help Measure Depth and Shape of Ice Shelf Fractures

When a block of ice the size of Houston, Texas, broke off from East Antarctica's Amery Ice Shelf in 2019, scientists had anticipated the calving event, but not exactly where it would happen. Now, satellite data can help scientists measure the depth and shape of ice shelf fractures to better predict when and where calving events will occur, according to researchers.

Global Ocean Model Offers New Insight into Baby Sea Turtles

An exquisitely detailed global ocean model simulation from the National Center for Atmospheric Research (NCAR) has given scientists rare insight into where baby sea turtles may go in their "lost years" after they scramble off the sandy beaches where they are born and swim into the open ocean.

Climate Change Possibly Caused Atlantic Warming During Pre-Industrial Era

A group of climate scientists analyzing a wide range of climate modeling experiments have found that volcanic eruptions, and not natural variability, caused an evident “Atlantic Multidecadal Oscillation,” a so-called cycle of warming considered to have taken place for about 40 to 60 years during the pre-industrial era.
