Oklahoma, USA – The National Weather Service (NWS) has issued a flash flood emergency for the first time in the Oklahoma City metro area. Over 3 inches of rain fell at Will Rodgers World Airport in the span of a single hour on Wednesday. Furthermore, the National Weather Service in Norman, Oklahoma states that 7.10 inches throughout the day, making it the wettest May day on record.

The tornadoes that hit Oklahoma and rural parts of Kansas and Nebraska have destroyed dozens of homes and overturned cars. The tornado caused worst damage in the Oklahoma City area where homes at Bridge Creek, Amber and Blanchard have been destroyed. About 10 homes have been destroyed in Amber and 25 have been destroyed in Bridge Creek. That storm also flipped vehicles on Interstate 35 and left power lines strewn across the roadway. Another tornado hit a zoo in Grady County, about 25 miles southwest of Oklahoma City. The storms also dumped up to 6 inches in the southern part of Oklahoma City, causing a flash flood emergency for the first time in its history.

Denver, Colorado, USA – Days of heavy rain over the Denver metro area have caused street flooding and the South Platte River to overflow its banks in some places. The river went over its banks in Confluence Park on Tuesday afternoon during a heavy rain storm.

Bahamas – Severe thunder storms on May 5th in Harbour Island, Eleuthera floods homes and shops. Water levels rose half way up doors, and residents lost most of their belongings, including all their vehicles. It all happened within a few hours.

Global Warming

A Global Milestone: CO2 Passes 400 PPM

For the first time since record keeping began, carbon dioxide levels have surpassed 400 parts per million (ppm) globally, according to newly published data for March. CO2 emissions are the main driver of climate change and have risen more than 120 ppm since pre-industrial times. The planet has warmed 1.6°F over that period as well.

This isn’t the first time 400 ppm has made news. In May 2013, CO2 measurements taken at Mauna Loa surpassed 400 ppm for the first time. Measurements have been taken continuously at the site since 1958 and present the longest running record of atmospheric CO2 on the planet.

In April of last year, 12 observatories in the northern hemisphere, including Mauna Loa, averaged 400 ppm for the first time on record. And Mauna Loa rang in 2015 by registering a 400 ppm measurement, the earliest occurrence on record for the site.

But what makes the new record more profound is that 400 ppm is officially part of the global record. Concentrations will likely remain above that mark until May when blooming plants in the northern hemisphere start to suck CO2 out of the air.

Volcanos

Roundup of Global Volcanic Activity

Hakone (Honshu): An eruption warning has been declared for the volcano, as increased seismic activity under the Ōwakudani hydrothermal field were registered during the past days and could herald sudden phreatic explosions.

The Owakudani valley lies north of the central lava domes inside the Hakone caldera. Seismicity started to increase in late April, consisting mostly of swarms of shallow quakes at 2 and 5 km depth. More intense swarms have occurred during the past days, triggering the Japan Meteorological Agency (JMA) to raise the alert level of the volcano to 2.

Bulusan (Luzon Island, Philippines): New, sporadic explosions have occurred at the volcano since 1 May, ejecting small plumes of ash. PHILVOLCS raised the alert level to 1 and an exclusion zone of 4 km around the volcano is in place.

According to the monitoring volcanologists, the activity has been phreatic in origin, i.e. caused by overheated ground-water rather than fresh magma at the surface.

Batu Tara (Sunda Islands, Indonesia): Several ash plumes were detected on satellite imagery during the past days, suggesting a phase of elevated activity.

Sinabung (Sumatra, Indonesia): The lava dome and its viscous lobe continue to grow slowly at the summit. It is probably only a matter of time until new collapses again trigger potentially very dangerous.

Turrialba (Costa Rica): A new series of weak to moderately powerful eruptions have occurred at the volcano during the past days.

A small and short ash eruption occurred on 1 May, with a plume of a few hundred meters height. On 4 May, a more intense eruption occurred at 13:20 local time, ejecting an ash column that rose 2.5 km and caused ash fall in areas of the Central Valley to the west, before drifting over the Pacific 100 km distance.
