The heat is on this summer as sweltering temperatures are felt throughout the U.S., all thanks to the “tipping point”— a warning once echoed in the 2015 Paris accord. The “tipping point,” a 2 degrees Celsius of warming above pre-industrial levels that was forewarned in 2015, has arrived and hit the U.S. with extreme climate change , leaving 34 million people living in areas that are rapidly heating. Related: Climate change will push 120 million into poverty The fastest state to experience such extreme warming is Alaska , a state where summer temperatures generally range from 55 to 70 degrees Fahrenheit, has seen a recent increase of heat waves and wildfires . Other areas of the Northeast, including New Jersey, Connecticut, Maine, Massachusetts and Rhode Island, who was the first state to pass the 2 degree Celsius, have also seen climes beyond normal. According to the Washington Post, most regional increases were due to warmer winters rather than summer heat waves. Less snowfall and ice mean those areas aren’t as likely to reflect solar dispersion during the winter months, ultimately feeding into a warming period. Although scientists can’t figure out why the Northeast is warming so rapidly, some experts believe the 2-degree Celsius hotspots are a glimpse into our future. Aside from the higher than average regional temperatures, there are also other factors that pose a threat to U.S. communities such as cold, heat, flooding, drought and even rising sea-levels. Four of the top five cities with the “lowest degree of readiness” are in Southern California alone (Anaheim, San Bernardino, Santa Ana and Riverside) and have all reached between 1.8 degrees Celsius and 2.1 degrees Celsius of warming compared to pre-industrial levels. While it may be summer in the U.S., some communities have experienced a real climate crisis , signaling climate change needs to be addressed now. Via Grist, Washington Post Image via Isengardt

Tipping points accelerated climate change in the last Ice Age, new research shows

Comments Off on Tipping points accelerated climate change in the last Ice Age, new research shows

Could reaching environmental tipping points really impact the Earth’s climate all that much? New research from an international team of four scientists says yes. Their study is the first to show that in our planet’s past, gradual changes in carbon dioxide (CO2) concentrations led to tipping points that then set off temperature spikes of as much as 10 degrees Celsius in only a few decades. Scientists led by Xu Zhang of the Alfred Wegener Institute were able to show how sudden changes in our climate, or Dansgaard-Oeschger events, came from CO2 concentrations that rose gradually. Researchers had known temperatures shot up thanks to Greenland ice core samples, but they weren’t sure why – and the new study provides some answers. Zhang said in a statement, “With this study, we’ve managed to show for the first time how gradual increases of CO2 triggered rapid warming .” Related: Scientists warn of uncontrollable climate change amid drastic Arctic melt The team drew on a climate model to find how interactions between the atmosphere and ocean currents led to the temperature spike of 10 degrees Celsius, or 18 degrees Fahrenheit, in Greenland during the last Ice Age, which ended around 11,700 years ago. Here’s how it works. Increased CO2 strengthened Central America trade winds, and the eastern Pacific Ocean warmed more than the western Atlantic Ocean. From there more moisture left the Atlantic, so the salinity and density of that ocean’s surface waters increased. These changes resulted in an abrupt amplification of the circulation pattern of the Atlantic, which according to Zhang can lead to sudden temperature increases. Will we see rapid changes if we hit tipping points today? Gerrit Lohmann of the institute and the University of Bremen said, “We can’t say for certain whether rising CO2 levels will produce similar effects in the future, because the framework conditions today differ from those in a glacial period. That being said, we’ve now confirmed that there have definitely been abrupt climate changes in the Earth’s past that were the result of continually rising CO2 concentrations.” The journal Nature Geoscience published the research online this month.

Artist "attacks" buildings with clutter to remind us of how much stuff we own

Comments Off on Artist "attacks" buildings with clutter to remind us of how much stuff we own

Torres has been working and living in Quebec for over a decade, where much of his artwork has been publicly displayed. “Tipping Point” was brought to Ottawa after the artist was invited by Canadian Heritage and EXMURO arts publics for an early July installation. Kayaks, construction cones, children’s toys, and patio chairs in bright, alarming colors seem to explode out of the side of the wall as observers pass by the piece. Related: Artist Veronika Richterová turns plastic bottles into beautiful plant and animal sculptures The piece is much like earlier works at a Quebec City event, named “Overflows” and “Stock in Transit”. The former portrays an explosion of multicolored plastic equipment bursting out of a tipped storage container, a metaphor for our disturbing reliance on accumulating as many things as we can buy. Each piece is meant to feel imposing and overwhelming, just like the western world’s love affair with “disposable” plastic objects. Most recently Torres’ “Canopy” piece was featured in Edmonton’s The Works Art & Design Festival . Visitors walked underneath and amongst exposed and covered passageways. The experience is meant to represent nomadism, a key theme in the artist’s life and creative work. +José Luis Torres Images via José Luis Torres

US coastlines will be flooding 30 times a year by 2050

Comments Off on US coastlines will be flooding 30 times a year by 2050

By 2050, huge areas of the US coast could be subject to more than 30 days of flooding each year, thanks to accelerating sea level rise from global warming. Recent data from the National Oceanic and Atmospheric Association identifies 2050 as the “tipping point” for nuisance flooding, which refers to floods that see water levels 1 to 2 feet above local high tide. The NOAA says these tipping points will affect all US coastlines , and they’ll even be exceeded in many areas.
