the impact of salting roadways

fri, 09 mar 2018 09:32:21 +0000

did you know that the salt used to deice roads harms the environment? the salty runoff gets into water ways, making our water taste salty and hurting plants and animals nearby. you can advocate to change unhealthy salting practices by talking to your local department of transportation today!

to adopt or to adapt: that is the question

mon, 22 dec 2014 10:22:22 +0000

i’m from a small town called eastchester, new york, just north of new york city. for me, climate change could mean no more farmers’ markets with my grandmother after sunday mass. upstate agriculture will be plagued by excessive heat once temperatures increase by more than 3 degrees celsius and farm fresh vegetables on the dinner table will be replaced with pre-packaged “alternatives.”

specialized agricultural techniques may not be enough to keep the food coming, according to william nordhaus’s climate casino.

it’s not just my sunday trips that will change, though – based on the national climate assessment, everyone in the northeast region of the country should be wary of increasing temperatures, precipitation and sea level rise. the evidence is growing larger as our time to act is shrinking. we’re on the path to finding out what climate change means for us the hard way.

this is one risk we should not be willing to take. even if there was a way to maintain my favorite broccoli and cauliflower supply at the market, getting the food to town poses another significant problem.

the predicted 71% increase in heavy precipitation will permanently flood the bronx river parkway. major traffic on other routes will become the norm as families struggle to clock in on time for work and have a tedious experience even grabbing a good burger in the next town over.

the bronx river parkway has its name for a reason. water originally filled the route before we came along with cement and a tractor, and all signs are pointing toward water filling it again. all solutions are costly, but with no place for another parkway, elevating the roads might be the only viable option unless people want to start kayaking around the county.

frequently traveling by water is one thing – drinking it is another. the quality of water is also greatly at risk.

sea level rise will increase salt-water intrusion into the hudson river. the hudson river runs into the state’s water supply, meaning drinking water quality is guaranteed to diminish. costco will prosper due to the increase in water bottle sales. everyone else will pay the price.

eastchester is in the same position as the rest of the globe. the best solution is prevention. we cannot save our crops once we go beyond the point of no return and there is no conceivable way to drain inches of water from the ocean. between increasing temperatures, precipitation and sea levels, the earth is slowly consuming our habitat. nature is supposed to be an ally of mankind, but we are slowly turning the environment into an undefeatable adversary.

new yorkers need to adopt favorable climate practices before they are forced to adapt to an unfavorable climate.

salt-free farming

mon, 19 mar 2012 17:03:41 +0000

unsw’s associate professor greg leslie has developed new technology that could offer new hope to farmers in drought-affected and marginal areas by enabling crops to grow using salty water.

the new technology uses reverse osmosis membranes to filter salty water and direct the water directly to the plants’ roots without damaging the crops.

adapting our lives, changing our legacies

vietnam is one of the 10 countries considered most vulnerable to climate change. how are the people there coping with the changes? what are they doing to adapt? pisa, partnerships for international strategies in asia, is a project based out of the george washington university that has a long history working in southeast asia. we went to a rice growing community in nam dinh province in vietnam to discover what adaptation strategies are taking place there.

science nation – marshes and sea level rise

mon, 25 jul 2011 16:48:19 +0000

with support from the national science foundation, villanova university marine scientist nathaniel weston studies how both land use and climate change can impact habitat in tidal marshes, including how rising sea levels may affect microbes and other plants and animals. rising sea levels can actually cause marshes to grow in very different ways. his experiments are already simulating different amounts of sea level rise in several tidal creeks in the delaware river estuary. he studies how salt-water intrusion impacts freshwater marsh stability, which is something a lot of regions around the world will be dealing with during climate change events.

thorium molten salt reactors – the silver bullet

sun, 10 jan 2010 14:00:00 +0000

they say there’s no such thing as a silver bullet when it comes to environment and energy. however, the liquid fluoride thorium reactor – lifter – comes pretty close.

peaking petroleum and a tight uranium equation have promped a surge in interest for new sources of energy. 9-11 has resulted in additional safeguards being placed on the nuclear business-as-ususal, meaning gallopping costs and hesitant investors. all of the northern hemisphere was exposed to the cold snap, a result of a quiet sun and a pacific decadal oscillation taking on a cold phase.

is there really such a nuclear system that 1) eats way the longlived waste, 2) has built-in-stability against runaway, 3) is cheap and massproducable and 4) is unattractive for military purposes ? well, fortunately yes.

the lifter is only a few years of relevant test runs away, building on the immense experience gathered at oak ridge national labs in the late 60s. it will provide affordable, depoyable, abundant, practical, easy and versatile power to industrialised and developing nations alike. the usamas of this world will not be tempted since the hurdles to illicit bombmaking are many and fundamental.
