NASA Scientists Link Earlier Melting Of Snow To Dark Aerosols
It's not easy to see aerosols in Earth's atmosphere, but they're there. And NASA scientists say these tiny particles are having a profound effect on snowpack and spring climate in the Northern Hemisphere. At any moment, millions of tons of aerosols lifted by winds and generated by wildfires and the burning of fossil fuels are traveling across the globe. In snowcovered regions, certain kinds of aerosols can darken the snow and ice causing it to absorb more of the sun's energy and melt faster. Scientists call this phenomenon the snow darkening effect.
The snow darkening effect is basically another way of saying what happens when snow gets dirty. Snow that has become darkened by aerosols absorbs more sunlight, than snow that is pristine. This may not seem significant, but it can actually have a big effect on the melting during spring. Using a NASA climate model, researchers studied the impact of three types of aerosols on snowpack in the Northern Hemisphere spring, specifically dust, black carbon, and organic carbon. The areas colored red to purple on this map show where the surface absorbed more energy from the sun.
Due to snow that has become darkened by these aerosols. This surface warming resulted in reduced amounts of snow in spring, shown here in areas colored blue. These reductions might reflect an earlier melting of winter snowpack and ground warming of areas normally covered by snow. In some places, temperatures are up to about 10 degrees Fahrenheit warmer than it would be if the snow were pristine. As we add more of these aerosols to the mix, we are changing the makeup of particles in the air and snow, potentially increasing our overall impact on Earth's climate.
The Beast Ebike by Daymak Toronto, Ontario
Gas prices are on the rise pollution is getting worse traffic is not getting any better the solution to city driving riding ebikes are much more popular these days and now people are using them as their main means of transportation but they do have limitations you or you can only ride them on paved roads you need to plug them in. We spent over two years developing this product. We wanted something different something unique we came up with the beast the beast is an on road and an offroad bike that goes.
Anywhere and charges anywhere just imagine you can ride anywhere from the beach to the trails offroad or in in the city what makes his bike unique it's a solar battery pack that we developed it features three solar panels that trickle charge battery continuously it adds up to ten kms per day or seven miles for every 10 hours of daylight so while you're sitting or what you're writing the bike is recharging you go to work you come back and your batteries are charged California Utah Nevada it also comes with USB ports we can plug in your iPod to iPod on your notebook.
And it is actually portable so you use it as a battery backup generator this ebike thanks to this technology is one of the greenest vehicles on the market today it's been really exciting riding the Beast electric bicycle around people's reaction has given us a lot of feedback that we have incorporated in our Design we at Daymak believe in creating cool products that reduce the carbon footprint we believe with the Beast we have actually accomplish that and then some it's useful it goes anywhere and it's a green product the Beast.
Keeping Campus Open and Accessible During Winter Weather Events
We make all of the snow disappear. Shovel sounds That's roughly 90 miles of sidewalk, 300plus buildings. We use saltbrine applications for snow events and ice and then we also use plows, brooms, blowers, whatever we need to get the snow off of the walk. We pretreat the roads and what that allows us to do is put salt on the road that stays on the road so the bond between the snow that falls and the weather that comes in doesn't bond to the roads. so the roads are easier to plow.
Plow sounds We have our bag of ice melt and our snow shovels we will get all of that into a big Brute Barrel that way we can take it from entrance to entrance. We do like to plow the snow off the walk before people walk down so if you see us rushing in front of you that's what we are usually trying to do, clear the path for you. It is a team effort, it does take all of us working together. We have a great staff of people here.
Steps to protect your home from snow and ice
OVER THE THE FLOOR. THEY ARE ARE NOT SURE AT THIS PUNT HOW MUCH DAMAGE WAS DONE. SNOW AND ICE BUILDUPS ARE CAUSING SERIOUS DAMAGE TO HOMES. NEWSCENTER5 KELLEY TUTHILL TONIGHT LAYS OUT THE STEPS YOU NEED TO TAKE TO PROTECT YOUR HOME AND YOU WALLET. THE AT HOMES THROUGHOUT NEW ENGLAND THEY ARE CHIPPING AWAY AT ICE AND SCRAPING DOWN THE SNOW IN A BATTLE TO SAVE THEIR HOMES FROM MOTHER NATURE'S WRATH. I HAVE BEEN LUCK. SO FAR, NO WATER YET. SO I GOT TO GET THIS HERE DONE.
OTHER HOME OWNERS HAVE NOT BEEN AS LUCKY. USING BUCKETS AND RAGS TO SOAK UP WATER LEAKING INSIDE. AARONSON INSURANCE IN NEEDHAM IS FIELDING 30 CALLS A DAY. THEY SUGGEST EVEN IF IT IS JUST A SMALL DRIP FILE A ERROR THE WITH YOUR INSURANCE COMPANY IN CASE IT GETS WORSE. SO IF YOU ARE HAVING A PIPE BURST OR JUST A LOT OF WATER COMING INTO THE HOUSE, THEY WANT TO GET IN AND CLEAR OUT THE WALLS AND TRY TO GET SOME FANS ON THEM TO MITIGATE MOLD. TAKE PICTURES OR VIDEO OF ANY.
DAMAGE AND KNOW THAT MANY POLICIES ONLY COVER WATER DAMAGE TO YOUR HOME NOT THE YOUR BELONGINGS. ONE OF THE FIRST THINGS WE TELL THEY WILL IS THEM IS TO REMOVE ANY FURNITURE OR ELECTRONICS, TV'S FROM THE ROOM. DON'T HAVE REPAIRS DONE WITHOUT PRY ARE APPROVAL FROM THE INSURANCE COMPANY AND THE STATE IS WARPING THAT MANY COMPANIES ADVERTISE THEY ARE LICENSED WHEN IN FACT THEY ARE NOT. YOU DON'T NEED A LICENSE FOR THAT TYPE OF SNOW REMOVAL AND ICE REMOVAL BUT YOU DO NEED A LICENSE PORE MINOR ROOF REPAIRS.
