    Your summer in extreme weather

    California drought

    Since May, California has faced a historic drought, resulting in the loss of 63 trillion gallons of water. 95.4 percent of the state is now experiencing "severe" drought conditions, which is only a marginal improvement from 97.5 percent last week.

    A recent study published in the journal Science found that the Earth has actually risen about 0.16 inches in the past 18 months because of the extreme loss of groundwater. The drought is particularly devastating for California's enormous agriculture industry and will cost the state $2.2 billion this year, cutting over 17,000 jobs in the process.

       

    Meteorologists blame the drought on a large zone (almost 4 miles high and 2,000 miles long) of high pressure in the atmosphere off the West Coast which blocks Pacific winter storms from reaching land. High pressure zones come and go, but this one has been stationary since December 2012.

    Great Plains tornadoes

    From June 16-18 this year, the Midwest was slammed by a series of four tornadoes, all ranking as category EF4--meaning the winds reached up to 200 miles per hour. An unlucky town called Pilger in Nebraska was hit especially hard, suffering through twin tornadoes, an extreme event that may only occur every few decades. The two that swept through the town killed two people, injured 16 and demolished as many as 50 homes.   

    "It was terribly wide," local resident Marianne Pesotta said to CNN affiliate KETV-TV. "I drove east [to escape]. I could see how bad it was. I had to get out of there."   

    But atmospheric scientist Jeff Weber cautions against connecting these events with climate change. "This is not a climate signal," he said in an interview with NBC News. "This is a meteorological signal."

    Michigan flooding

    On Aug. 11, Detroit's wettest day in 89 years -- with rainfall at 4.57 inches -- resulted in the flooding of at least five major freeways, leading to three deaths, more than 1,000 cars being abandoned on the road and thousands of ruined basements. Gov. Rick Snyder declared it a disaster. It took officials two full days to clear the roads. Weeks later, FEMA is finally set to begin assessing damage.   

    Heavy rainfall events are becoming more and more common, and some scientists have attributed the trend to climate change, since the atmosphere can hold more moisture at higher temperatures. Mashable's Andrew Freedman wrote on the increasing incidence of this type of weather: "This means that storms, from localized thunderstorms to massive hurricanes, have more energy to work with, and are able to wring out greater amounts of rain or snow in heavy bursts. In general, more precipitation is now coming in shorter, heavier bursts compared to a few decades ago, and this is putting strain on urban infrastructure such as sewer systems that are unable to handle such sudden influxes of water."

    Yosemite wildfires

    An extreme wildfire burning near Yosemite National Park forced authorities to evacuate 13,000 nearby residents, while the Madera County sheriff declared a local emergency. The summer has been marked by several wildfires due to California's extreme drought, which causes vegetation to become perfect kindling.   

    Surprisingly, however, firefighters have done an admirable job containing the blazes. According to the L.A. Times, firefighters with the state's Department of Forestry and Fire Protection have fought over 4,000 fires so far in 2014 -- an increase of over 500 fires from the same time in 2013.

    Hawaii hurricanes

    Hurricane Iselle was set to be the first hurricane to make landfall in Hawaii in 22 years. It was downgraded to a tropical storm and didn't end up being nearly as disastrous as it could have been, but it still managed to essentially shut down the entire state for a day, as businesses and residents hunkered down in preparation, with many boarding up their windows to guard against strong gusts. The storm resulted in downed trees, 21,000 people out of power and a number of damaged homes.

    Debbie Arita, a local from the Big Island described her experience: "We could hear the wind howling through the doors. The light poles in the parking lot were bobbing up and down with all the wind and rain."

    Florida red tide

    A major red tide bloom can reach more than 100 miles along the coast and around 30 miles offshore. Although you can't really see it in the above photo, the effects are devastating for wildlife. This summer, Florida was hit by an enormous, lingering red tide, also known as a harmful algae bloom (HAB), which occurs when algae grow out of control. HABs are toxic to fish, crabs, octopuses and other sea creatures, and this one resulted in the death of thousands of fish. When the HAB gets close enough to shore, it can also have an effect on air quality, making it harder for people to breathe.   

    The HAB is currently closest to land near Pinellas County in the Gulf of Mexico, where it is 5-10 miles offshore.

    Pond de l'Archeveche - hundreds thousands of padlocks locked to a bridge by random couples, as a symbol of their eternal love. After another iconic Pont des Arts bridge was cleared of the padlocks in 2010 (as a safety measure), people started to place their love symbols on this one. Today both of the bridges are full of love locks again.

    On a weekend trip to buffalo from Toronto we made a pit stop at Niagara Falls on the Canadian side. I took this shot with my nexus 5 smartphone. I was randomly shooting the falls themselves from different viewpoints when I happened to get a pretty lucky and interesting shot of this lone seagull on patrol over the falls. I didn't even realize I had captured it in the shot until I went back through the photos a few days later

    Lucky timing! The oxpecker was originally sitting on hippo's head. I could see the hippo was going into a huge yawn (threat display?) and the oxpecker had to vacate it's perch. When I snapped the pic, the oxpecker appeared on the verge of being inhaled and was perfectly positioned between the massive gaping jaws of the hippo. The oxpecker also appears to be screeching in terror and back-pedaling to avoid being a snack!

    This wave is situated right near the CBD of Sydney. Some describe it as the most dangerous wave in Australia, due to it breaking on barnacle covered rocks only a few feet deep and only ten metres from the cliff face. If you fall off you could find yourself in a life and death situation. This photo was taken 300 feet directly above the wave from a helicopter, just as the surfer is pulling into the lip of the barrel.
