Food System Shock: Climate Change's Greatest Threat to Civilization

http://www.wunderground.com/blog/JeffMasters/food-system-shock-climate-changes-greatest-threat-to-civilization

The greatest threat of climate change to civilization over the next 40 years is likely to be climate change-amplified extreme droughts and floods hitting multiple major global grain-producing "breadbaskets" simultaneously. A "Food System Shock" report issued in 2015 by insurance giant Lloyd’s of London outlined a plausible extreme shock to global food production that could cause rioting, terrorist attacks, civil war, mass starvation and severe losses to the global...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3294">Read More</a>

The World Meteorological Organization (WMO) announced last week that three tropical cyclones from 2015 would get their names retired--Hurricane Joaquin and Tropical Storm Erika in the Atlantic, and Hurricane Patricia in the Eastern Pacific. The WMO will replace Erika with “Elsa”, Joaquin with “Julian” and Patricia with “Pamela” when the 2015 lists are reused in 2021.

The two new retired names in the Atlantic brings the total number of storm na...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3293">Read More</a>

A Twist to Tuesday’s Severe Weather: Tornadoes Missing

http://www.wunderground.com/blog/JeffMasters/a-twist-to-tuesdays-severe-weather-tornadoes-missing

Tornado chasers scanned the skies fruitlessly on Tuesday, while residents of the Southern Plains breathed huge sighs of relief, as a bumper crop of severe thunderstorms produced buckets of large hail and high wind while spinning up only a handful of twisters. By mid-morning Wednesday, NOAA’s Storm Prediction Center (SPC) had received only five tornado reports: two in Texas, and one each in Kansas, Missouri, and Indiana. All of these tornadoes were relatively minor...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3292">Read More</a>

Southern Plains Bracing for Potential Tornadoes, Huge Hail

http://www.wunderground.com/blog/JeffMasters/southern-plains-bracing-for-potential-tornadoes-huge-hail

Damaging tornadoes--and hailstones larger than baseballs--may crop up later Tuesday along a swath from southern Nebraska to central Texas, as a long-predicted outbreak of severe weather takes shape. NOAA’s Storm Prediction Center (SPC) has draped a moderate-risk area--the second-highest of SPC’s risk categories--from southern Nebraska into northern Texas. Despite the high confidence that widespread severe weather will occur, there remains uncertainty over exactl...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3291">Read More</a>

Busy Week of Severe Weather Ahead for Nation’s Midsection

http://www.wunderground.com/blog/JeffMasters/busy-week-of-severe-weather-ahead-for-nations-midsection

In classic late-April fashion, the ingredients are coming into play for severe thunderstorms to prowl the central United States across several days over the coming week. The whole gamut of severe threats is likely to materialize before the week is out, from tornadoes to enormous hail, strong downburst winds, and torrential downpours. Residents of Texas and Louisiana hard-hit by flooding in recent weeks face another stretch with the potential for very heavy rain that...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3289">Read More</a>

A WunderPhoto-graphic Salute to Earth Day

http://www.wunderground.com/blog/JeffMasters/a-wunderphotographic-salute-to-earth-day

Today is the 47th annual Earth Day, a day to celebrate the beauty of the atmosphere, oceans, and biosphere of the planet that sustains us. This week I’ve had the distinct pleasure of picking a few of my favorite WunderPhotos uploaded to our website over the past year, in keeping with the Earth Day tradition established by Dr. Jeff Masters (who’s off today). The photos below are all drawn from our World View Gallery, which is updated weekly with the top WunderPho...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3288">Read More</a>

Atmospheric CO2 Leaps into Uncharted Territory: 408 ppm

http://www.wunderground.com/blog/JeffMasters/atmospheric-co2-leaps-into-uncharted-territory-408-ppm

Even as it fades, the 2015-16 El Niño has given a big boost to the annual spring peak of carbon dioxide in the atmosphere. Preliminary CO2 data from Mauna Loa, Hawaii, for the week ending April 16 showed a concentration of 408.69 parts per million (ppm), according to NOAA. The weekly value analyzed by NOAA topped 405 ppm for the first time on March 26 (405.62 ppm), which was itself surpassed by 406.57 ppm on April 9. The one-day average concentration hit an eye-ope...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3287">Read More</a>

Fantala Tied for Strongest on Record for Indian Ocean; Massive Flash Flood in Houston

Fierce Tropical Cyclone Fantala stormed to Category 5 strength north of Madagascar over the weekend with an impressive burst of strengthening, making the cyclone as strong as any on record anywhere in the Indian Ocean. Fantala’s estimated peak sustained winds of 150 knots (173 mph), averaged over 1 minute by the Joint Typhoon Warning Center, are tied with those of Tropical Cyclone Agnielle (November 1995 peak 1-minute winds of 150 knots) as the strongest in the So...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3285">Read More</a>

Warmest March in Global Recordkeeping; 2016 Roars Ahead of Pack

http://www.wunderground.com/blog/JeffMasters/warmest-march-in-global-recordkeeping-2016-roars-ahead-of-pack

March 2016 was by far the planet's warmest March since record keeping began in 1880, and was also the warmest month relative to average of any month in the historical record, said NOAA's National Centers for Environmental Information (NCEI) on Tuesday. In the NOAA database, March 2016 came in a full 1.22°C (2.20°F) warmer than the 20th-century average for March of 12.7°C (54.9°F), as well as 0.32°C (0.58°F) above the previous record for March, set in 2015.
