مهرداد جان استاد بنده هستند و نظرشون واسه من خیلی محترمه:گل:
بهرحال ایشون منابع خودشون رو دارند و بنده هم همینطور.
منابع من میگن که از دوشنبه همین هفته تا روزهای پایانی هفته کشور ما درگیر بارش به شکل باران و برف و کاهش محسوس دما خواهد شد.
برای هفته دوم دی ماه هم فعلا نظر خاصی ندارم.

It’s Not Too Late to Limit Global Temperatures - But Almost
By Michael D. Lemonick
Follow @MLemonick
For a couple of years now, climate scientists have agreed that to avoid the most serious consequences of global warming we need to cap the planet’s average temperature at no more than 2 degrees C (or 3.6°F) above where it stood in the 1800s. The temperature has already risen by about 1°C -- the longer we wait to rein in greenhouse-gas emissions, the harder it will be to reach that goal — and the recent international climate talks in Doha made it clear that emissions aren’t likely to be reined in anytime soon.
This raises the question of how much more those emissions could grow before the 2°C target becomes physically impossible to achieve. And a recent paper in Nature Climate Change has a somewhat encouraging answer. Even if annual emissions nearly double by 2020 from today’s 30 billion tons or so, it would still be possible to cap the temperature rise at 2°C, or at worst, rise slightly above that level before coming back down.

That’s the good news. The bad news is that “possible” doesn’t mean “easy,” by a long shot. Capping temperatures after such a large increase in emissions would be “technically feasible,” co-author Brian O’Neill said in an interview, “but so many things would have to go right that you’d have to be a very optimistic person to bet that it would actually happen.”
O’Neill said the problem is that emissions would have to be cut quickly and drastically after 2020. The technology for doing so already exists, including nuclear power, biofuels and the capture and storage of carbon from power-plant smokestacks before it can enter the atmosphere.
“It would have to be feasible to scale all of them up globally, and they couldn’t be prohibitively expensive,” he said. “You’d have to retire most of the world’s coal-burning plants, and countries would have to work together to make it all happen.”
The good news, say the study’s authors, is that emissions needn’t double by 2020, especially if energy-hungry nations put some effort into improving the efficiency of cars, buildings, factories and other energy hogs.

“If we did nothing other than reduce energy demand through efficiency and lifestyle changes before 2020,” O’Neill said, “we could meet the 2°C target even if we didn’t build more nukes, or if we put limits on the amount of land devoted to biofuels” — two options that would otherwise be impossible.
Still, without some strong new agreements on emissions, meeting the 2°C target is likely to be a tall order given that nations would have to work together.
“Politics is a separate question,” O’Neill said, noting that the 2°C number is an international target that many countries have publicly agreed to in principle. “Whether they’re serious about it or not, we’re not judging.”
But this kind of study can still be useful. “It can inform what’s technically and economically feasible,” O’Neill said. “People need to understand implications of the temperature targets they’re agreeing to. I’m not sure they always do.”

دوستان این تصاویر رو امروز صبح از فراز قله زو - آب و برق گرفتم.
فقط دلم میخواد مقایسه کنید:
نمایی از شهر مشهد به سمت شمالی و شمال شرق که هزار مسجد و دامنه های جنوبیش به همراه اژدر کوه کاملا مشخص هستند. البته سمت راست بالای تصویر جنوب شرق مشهد ( فرودگاه و آلودگی هوا که غوغا میکنه)
نمایی به سوی شرق و جنوب شرق مشهد که آلودگی وحشتناکه:
و در انتها نمایی زیبا از هوای پاکیزه و تمیز در نواحی غربی و شمال غربی شهر مشهد:
سلام
البته اصلا نگران نباشید چون همکاران و دوستان محترم بنده از دوهفته پیش بزرگراه کمربندی جنوبی مشهد رو آغاز کردند و شاید از همین کوهها هم مسیرش عبور کنه و اون وقته که متاسفانه محیط زیست و البته هوای اونجا هم مثل بقیه نقاط شهر میشه!!!:ناراحت:

سلام جناب میری عزیز
متسفانه کاملا درسته خبرش رو چند روز پیش شنیدم!
حالا واقعا پروژه داره استارت میخوره!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
میشه جزئیات بیشتری از این بزرگراه رو در اختیار من و سایر دوستان عزیز قرار بدید.
خیلی ممنون

بارش اولین برف در شهرستان سمنان اول دی ماه 91(تفاوت رو احساس کنبد بیشتر نواحی سرد سیر بارون امده سمنان برف)
بقیه در لینک زیر

بزرگراه کمربندی جنوبی مشهد به طول 27 کیلومتر از بزرگراه برونسی فعلی شروع میشه و با حرکت به جنوب از پشت کوههای منطقه آب و برق و هاشمیه و ... عبور میکنه و تنها در برخی نقاط به شهر دید داره و بعد به امتداد بزگراه کلانتری ادامه پیدا میکنه و در عوارضی اگه اشتباه نکنم تموم میشه
پروژه شروع شده و بنیاد مسکن هم پیمانکار اون هست و البته برای اجرا هم فکر کنم نگرانی زیادی ندارن چون شهرداری کارفرماست و شهرداری جز پول امتیازات دیگه ای هم میتونه بده مثل تراکم و ....

[h=2]It Could be a White Christmas After All
[h=6]By Alex Sosnowski, Expert Senior Meteorologist [h=5]December 21, 2012; 1:50 PM

It could be a white Christmas after all in Pennsylvania, New Jersey, New York, New England and other areas across the nation.
Despite the fact that 2012 likely to finish up as the warmest year since at least 1950 in the United States, enough cold air is on the move to spread snow to locations that haven't seen that much over the past couple of years for Christmas.
The most recent storm, a major blizzard, put down a swath of heavy snow from Colorado to Michigan, and it is not done yet.
Part of a new storm, currently north of Hawaii, has a chance of tracking in just the right manner to spread a swath of snow beginning from the central Appalachians to the northern mid-Atlantic coast and southern New England spanning Christmas Eve into Christmas Day.
In the most likely scenario, the storm is not expected to become very strong, but rain showers and mild air would still be drawn northward into the Tennessee and Ohio valleys, the Carolinas, the Virginias, Maryland, Delaware and southern New Jersey.
As the storm glides toward the Atlantic coast, a change to snow is possible from the central Appalachians to areas farther east near the Mason-Dixon Line.

However, even with this portrayal, there is a chance of a period of accumulating snow from Harrisburg and Scranton, Pa., to Hartford, Conn., and Boston, where the air would stay cold enough on the front side, middle and tail end of the storm. In the swath from northern Maryland, Philadelphia and northern Delaware to central New Jersey, New York City and Long Island, part rain and part snow are most likely.
There is a remote possibility that the snow will mix in near the end of the storm system in Washington, D.C., and Baltimore, Md. Snow could also be flung as far north as Albany, N.Y., and Portland, Maine.

White Christmas Chances
If the storm were to grab sufficient moisture, accumulations would shift from a scenario bringing a coating to an inch or two to a scenario producing a half a foot of snow in some locations near and north of the Mason-Dixon Line to near the I-95 corridor in southern New England.
Areas from the Alleghenies to the Poconos, Catskills and Berkshires have the greatest potential to get several inches of snow from such a storm.
If the storm were to remain very weak, only rain showers and snowflakes would affect the mid-Atlantic with no significant accumulation.
In the wake of the Christmas snow potential in the Northeast, a second and larger storm is in the making beginning Christmas Eve and Christmas Day in the West.
That storm would also become much stronger than the East Coast system and will unload heavy snow from the Sierra Nevada to the Wasatch and central and southern Rockies spanning Christmas Eve and Christmas Day.
By the day after Christmas, as many seek to return their unwanted gifts or head home after visiting friends and family, the second storm is forecast to evolve into a monster over the middle and lower Mississippi Valley.
By then the second storm will have windswept snow on its northwest flank over part of the southern Plains and the Ohio Valley states, drenching rain to its east into the southern Appalachians and severe weather in the South.
That second storm is forecast to set its sights on the Northeast Wednesday night and Thursday with strong wind, areas of rain, thunderstorms and perhaps a blizzard on its northwest flank.
The exact track of the storms next week will determine where the rain/snow line sets up.
