Does the weather has been a bit weird recently?

In most of America, a severe heat wave warning is now in progress. In New York City the heat index that combines temperature and humidity measures reached 106F (41°C) today. Heat stress for people, animals, and plants can happen and the severe situation may last well over a week. Temperatures on the 4th of July could be sweltering in many places.

The Middle East is typically hot during the summer but one town in Oman, on the Arabian Sea, measured the highest night-time "low" temperature ever recorded on Earth, June 26th. The fishing village of Quriyat, with ~50,000 residents, had to live through 108.7F (42.6C) that night. Their extreme temperatures continue being measured.

In Asia, China has been experiencing the opposite effect of a warming atmosphere for multiple weeks. The heaviest rainfall in sixty years was measured falling in regions surrounding Beijing, China. While in Guang’an City, in China's southern Sichuan Province, received torrential downpours that caused widespread flooding. The city received the most rainfall measured in 147 years. A major landslides caused some of the city's infrastructure to collapse.

These are only ramdom samples of a changing climate but people everywhere are now experiencing what greenhouse gas measurements can mean to them in their daily lives. NOAA that manages the National Weather Service and has global monitoring satellites that continue to gather environmental measurements adding to the growing database on climate change in the US and elsewhere.

The National Academy of Sciences (NAS), whose membership includes climate scientists who have studyed global warming since the 1950's, has often commented: the frequency and intensity of extreme weather events, such as excessive heat waves and severe rainfalCutl, is a well-documented effect of a changing climate.

The "signals" of climate change are flashing.
