Tropical Storm Krosa continued to erode after it moved into the Sea of Japan and satellite data showed it as a ragged and shapeless storm on August 16, 2019.

A new study from the University of Helsinki using miniaturized satellite-based tags revealed that during drier periods desert bats must fly further and longer to fulfil their nightly needs. According to researchers this signals their struggle in facing dry periods.

When Earth's species were rapidly diversifying nearly 500 million years ago, that evolution was driven by complex factors including global cooling, more oxygen in the atmosphere, and more nutrients in the oceans. But it took a combination of many global environmental and tectonic changes occurring simultaneously and combining like building blocks to produce rapid diversification into new species, according to a new study by Dr. Alycia Stigall, Professor of Geological Sciences at Ohio University.

NASA's Aqua satellite provided forecasters at the Joint Typhoon Warning Center with infrared data and cloud top temperature information for Tropical Storm Krosa as it was making landfall in southern Japan.

Operational models for severe weather forecasting predicted Hurricane Harvey would become a Category 1 hurricane in 2017, according to the University Corporation for Atmospheric Research. Instead, it became a massive Category 4 just before it made landfall, tying Hurricane Katrina for the costliest hurricane on record.

A new in-depth study from Ryerson University called 'The influence of environmental and health indicators on premature mortality: an empirical analysis of the City of Toronto's 140 neighborhoods' assesses the impact of several environmental, health, socioeconomic and demographic characteristics on lifespan. Authors Luckrezia Awuor and Stephanie Melles determined that premature mortality in Toronto neighborhoods was predicted by a combination of unhealthy environments and embedded socioeconomic imbalances.

The Earth's carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate.
