California’s Ongoing Drought Linked To Climate Change

Using a sophisticated combination of computer simulations and statistical techniques, scientists at Stanford University have shown that the extreme atmospheric conditions associated with California’s lengthy drought are likely caused by today’s global warming conditions.

The new research shows that the immediate cause of the California drought appears to be a stubborn “blocking ridge” over the northeastern Pacific, which climate scientists have charmingly dubbed the Ridiculously Resilient Ridge, or “Triple R.” It prevented winter storms from reaching California during the 2013 and 2014 rain seasons. And according to lead researcher Noah Diffenbaugh, this persistent region of high atmospheric pressure was much more likely to form in the presence of modern greenhouse gas concentrations.

"Our research finds that extreme atmospheric high pressure in this region – which is strongly linked to unusually low precipitation in California – is much more likely to occur today than prior to the human emission of greenhouse gases that began during the Industrial Revolution in the 1800s," noted Diffenbaugh in a Stanford statement.

The new research, which will be added as a supplement to this month’s issue of The Bulletin of the American Meteorological Society, is being described as one of the most comprehensive studies to investigate the link between climate change and California’s ongoing drought. More from the Stanford statement:

Blocking ridges are regions of high atmospheric pressure that disrupt typical wind patterns in the atmosphere. “Winds respond to the spatial distribution of atmospheric pressure,” said Daniel Swain, a graduate student in Diffenbaugh’s lab and lead author of the study. “We have seen this amazingly persistent region of high pressure over the northeastern Pacific for many months now, which has substantially altered atmospheric flow and kept California largely dry.”

Blocking ridges occur periodically at temperate latitudes, but the Triple R was exceptional for both its size and longevity. While it dissipated briefly during the summer months of 2013, it returned even stronger by fall 2013 and persisted through much of the winter, which is normally California’s wet season.

"At its peak in January 2014, the Triple R extended from the subtropical Pacific between California and Hawaii to the coast of the Arctic Ocean north of Alaska," said Swain, who coined the term "ridiculously resilient ridge" last fall to highlight the unusually persistent nature of the offshore blocking ridge.

Like a large boulder that has tumbled into a narrow stream, the Triple R diverted the flow of high-speed air currents known as the jet stream far to the north, causing Pacific storms to bypass not only California but also Oregon and Washington. As a result, rain and snow that would normally fall on the West Coast was instead re-routed to Alaska and as far north as the Arctic Circle.

Using the Triple R as a benchmark, the researchers compared geopotential heights (i.e. an atmospheric property related to pressure) between two sets of climate model experiments. One set represented the current state of our climate and the associated levels of carbon dioxide and greenhouse gases, while the other was kept at a level similar to those that existed prior to the Industrial Revolution.

Computer modeling showed that the conditions associated with the Triple R are far more likely to occur now.

"In using these advanced statistical techniques to combine climate observations with model simulations, we’ve been able to better understand the ongoing drought in California," Diffenbaugh added. "This isn’t a projection of 100 years in the future. This is an event that is more extreme than any in the observed record, and our research suggests that global warming is playing a role right now."

Snowflakes are actually the perfect metaphor for people. Each one IS unique, but we all have the same structure and are pretty similar in spite of our differences. And really, with as many around as there is, aint no one gonna notice your differences unless they care enough to look closely.

People are also similar to snowflakes in that it is difficult to drive when there are too many of them piled up on the road.

Well that took a turn I didn’t expect

        When school was dismissed Anne marched out with her red head held high. Gilbert Blythe tried to intercept her at the porch door. “I’m awfully sorry I made fun of your hair, Anne,” he whispered contritely. “Honest I am. Don’t be mad for keeps, now.”
        Anne swept by disdainfully, without look or sign of hearing. “Oh how could you, Anne?” breathed Diana as they went down the road half reproachfully, half admiringly.
        "I shall never forgive Gilbert Blythe," said Anne firmly. "And Mr. Phillips spelled my name without an ‘e,’ too. The iron has entered into my soul, Diana."

Last Night in Ferguson (9.28-9.29): Last night’s protest was one of the in Ferguson this month, proving once again that the residents of Ferguson/STL County are some of the most resilient and inspiring in all the land. The police were literally holding peaceful protesters hostage late into the night (folks who were complying with all police requests) so they could negotiate with the remaining folks to leave, but the protesters didn’t back down. Eventually all arrestees were released, and many plan to be back out there tonight.

Injustice in Ferguson continues, but despite it, community now thrives too. This is still happening. Are you still paying attention? #staywoke #farfromover

attention passengers this is your pilot speaking, we’re going to be experiencing some heavy turbulence shortly so please strap in. this loser just bet that i couldn’t do a 360 barrel roll in this thing and let’s just say i’m about to be $20 richer real soon
