قله هاش که معلومه برف میاد
روستاهاش چی ؟

خوب عکس برفی از روستاهای هرمزگان گیر نیاوردم
اونچه که مسلمه از 1800 متر به بالا بارش برف زمستانه حتی در مناطق هم عرض و چسبیده به ساحل خلیج فارس ( مثل کوه گنو در 20 کیلومتری بندر عباس) اتفاق میفته پس میشه انتظار داشت در مناطق شمالی هرمزگان اگه روستایی حدود 1600 به بالا ارتفاع داشته باشه حداقل در زمستانهای پر بارش برف رو ببینن


1800 متر گنو 20 کیلومتری شمال بندر عباس

به گزارش مجله شبانه باشگاه خبرنگاران،،چابهار،بهشت گمشد ايران است.نگریستن به زیبایی های خلقت در چابهار خلیج چابهار زیباترین جلوه گاه طلوع و غروب خورشید در دریاست.

خلیجي که کمتر بین ايرانیان شناخته شده اما زيبايي هاي طبیعي اش آنقدر زياد است که اين منطقه را جزو بي نظیرترين مناطق گردشگري دنیا محسوب کرده است. در اين نوشتار به تعدادي از اين جاذبه هاي طبیعي اشاره م يکنیم.

تالاب ليپار

871008_129.jpg


لیپار از مناطق زيبا و طبیعى منطقه است. تالاب لیپار در 15 کیلومترى شرق چابهار نزديکى روستاى رمین و در در مسیر جاده ساحلى چابهار- گواتر قرار گرفته است. لیپار چشم انداز فوق العاده اى دارد. رويش گونه هاى بلوط و گزنه در آب صحنه فوق العاده زيبايى خلق کرده که در هیچ جاى ديگر ايران ديده نمى شود. در اين تالاب زيبا، پرندگانى چون لک لک، طاووس، کبک و مرغ ماهى خوار زندگى م ىکنند. کنار اين تالاب زيبا نیز دشتار قرار دارد که بومیان به آن عروس نیز م ىگويند.

علت اين نامگذارى، زيبايى منطقه و وجود درختان سرسبز و خرم است که می تواند پذيراى علاقه مندان به طبیعت باشد. دشتار در زبان بلوچ به دخترانى اطلاق مى شود که هنوز عروسى نکرده و به عبارتى در مرحله نامزدى به سر مى برند. در اين منطقه پنبه هايى وحشى به عمل م ىآيد که بومیان از آن تشک و بالش تهیه مى کنند.

همچنین اين منطقه، تاريخى طولانى را يدک مى کشد و داراى جاذبه هايى از جمله چاه هاى عمیق و گورستان هاى تاريخى است. جنگل حرا اين جنگل زيبا در ناحیه ساحلي خلیج گواتر در نزديکي محلي که رودخانه باهوکلات به درياي عمان مي ريزد قرار دارد حرا درختچه اي است که در مرداب هاي نواحي گرم در کرانه هاي عربستان، مصر و جنوب ايران مي رويد.

این جنگل زیبا در ناحیه ساحلی خلیج گواتر در نزدیکی محلی که رودخانه باهوکلات به دریای عمان می ریزد قرار دارد. حرا درختهچه ای است که در مرداب های نواحی گرم در کرانه های عربستان، مصر و جنوب ایران می روید.

رودخانه باهوكلات

اين رودخانه يکي از پرآب ترين رودهاي بلوچستان و عامل اصلي حیات در جنوب اين منطقه محسوب مي شود، اينجا محل زندگي تمساح ايراني است، اين جانور بازمانده خزندگاني است که در حدود 265 میلیون سال پیش مي زيسته اند. در حوزه حیات وحش نیز تمساح پوزه کوتاه برجسته ترين موجود منطقه چابهار است که به طور طبیعى و آزاد زندگى می کند.

871070_355.jpg


تمساح پوزه کوتاه در برکه هاى راسک، باهوکلات و باتلاق هاى دلگان و کلانى زندگى مى کند و تنها نوع تمساح ايران است که ارزش ملى و بین المللى دارد طول اين جانور تا چهار متر مى رسد و قوى ترين عضو آن دمش است.

اگر هم روزی تصمیم گرفتید که یک دریا واقعی و تمام عیار برید حتما به ساحل دریای بزرگ چابهار سر بزنید. منظورم خلیج چابهار نیست.

من یک بار در خرداد ماه اونجا رفتم و فوق العاده زیبا بود و دریایی زلال - شفاف - مرجانی با امواج سهمگین!!!!!!!!!!!

به جرات می تونم بگم در هیچ جایی از ایران یک همچین دریایی بافت نمی شود:

سه تصویر از مکانی تفریحی به نام دریای بزرگ در چابهار که چون دریا از اینجا مستقیما به اقیانوس وصله، به آن دریای بزرگ میگن. طول موجهای اینجا گاهی وقتها به 9 متر هم میرسه. مکان تفریحی زیبا وخوبیست و به خاطر امواج خروشان دریا در اینجا دمای هوا بسیار خنک تر از جاهای دیگه ی این شهره. البته از لحاظ خدمات توریستی و رفاهی و امکانات زیاد جالب نیست.

White House Rolling Out Sweeping Climate Measures

In a landmark day for U.S. climate science and policy, the Obama administration is set to announce a broad range of policies aimed at addressing global warming, including for the first time directing the Environmental Protection Agency to limit emissions of manmade greenhouse gases from both existing and proposed coal-fired power plants.
The president is scheduled to announce the "Climate Action Plan" during a speech at Georgetown University at 1:55 p.m. ET on Tuesday — his first address devoted solely to climate change. It follows several prominent speeches in which he mentioned the need to address the issue, most recently in Berlin last week.

The proposals, none of which require congressional approval, address everything from how federal agencies should take climate change risks into account when funding construction projects, to the need to slash emissions of global warming gases in addition to carbon dioxide (CO2). They amount to a sweeping climate plan, which includes measures to help the country adapt to near-term challenges, including more frequent and severe weather events, and the growing vulnerability of coastal locations to sea level rise and storm surge.
“President Obama is really resetting the climate agenda,” said Andrew Steer, president of the World Resources Institute in Washington.
The centerpiece of the administration’s proposal is the president’s request for the EPA to begin the rulemaking process for limiting greenhouse gas emissions from more than 1,000 existing coal-fired power plants. The EPA is already in the process of enacting rules governing emissions from new coal-fired power plants. In 2007, the Supreme Court paved the way for the EPA to regulate carbon dioxide, the most important long-lived greenhouse gas, under the Clean Air Act.

The new EPA proposal is likely to face court challenges from industry, since it will impose additional costs on electric utilities. And the process of devising, finalizing, and defending the rules in court may ultimately last well beyond the rest of Obama’s second term.

“We know that we have to get to work quickly in order to not only propose, but also finalize the rules,” said a senior White House official during a conference call with reporters on Monday.
“Climate change is no longer a distant threat,” the official said, noting that 2012 was the hottest year on record in the continental U.S., when one-third of all Americans experienced 10 days or more of 100-degree heat. The White House official also cited rising food prices due to drought, the fact that the 12 hottest years on record globally have all come in the past 15 years, and the growth in asthma cases related to air pollution as examples of why action is needed.

“In spite of these trends, Congress has not acted,” the official said.
No plan to address the U.S. contribution to global warming could be effective without addressing emissions from the power sector. About 87 percent of all manmade emissions of greenhouse gases in the U.S. are energy-related, according to a White House report sent to Congress in March, and existing coal power plants are responsible for 34 percent of annual energy-related U.S. greenhouse gas emissions.
The proposed measures would put the U.S. on course to meet its near-term emissions reduction targets set in the Copenhagen Climate Accord in 2009, in which President Obama pledged to reduce its greenhouse gas emissions by 17 percent below 2005 levels by 2020.

“Today, the president remains fully committed to that goal,” said the senior White House official.
The president’s speech on Tuesday comes in the midst of a transformation in the domestic energy industry, with a doubling in the use of wind, solar, and geothermal energy during the president’s first term, and the rise of natural gas at the expense of dirtier coal-fired power plants. The Obama administration is expected to propose to once again double domestic renewable energy production, this time by 2020, including by siting renewable energy infrastructure, such as wind turbines and solar panels, on public lands and buildings.
During the past five years, energy-related greenhouse gas emissions have fallen, allowing for some progress to be made toward meeting the Copenhagen Accord target. The White House report to Congress found that the biggest reason for the decline in energy-related emissions was the economic downturn that began in 2007, and that as the economy gains steam, energy-related emissions will increase again unless other policies are put in place to limit them. And in fact, the U.S. saw emissions rise more than 7 percent in the first quarter of this year as utilities started using more coal when natural gas prices increased.
The switch from coal to natural gas and renewables, as well as energy efficiency improvements, have played key roles in driving energy-related emissions lower in recent years. In 2012, net oil imports fell to their lowest level in 20 years, and the U.S. became the world’s leading natural gas producer.

“This is a moment that’s been 20 years in the making . . . and most of the past 20 years unfortunately has not been very well spent,” said David Hawkins of the Natural Resources Defense Council (NRDC), an environmental advocacy group. The NRDC released a report earlier this year that found that limiting emissions from coal-fired power plants would cost the industry about $4 billion in compliance costs, but would provide $25 billion to $60 billion in net benefits, including through improved public health and reduced costs from long-term climate change.
In addition to taking action to reduce greenhouse gas emissions, the Obama administration also announced several measures aimed at preparing the country for the impacts of global warming.
For example, the president is expected to mention in his Georgetown speech that he is directing federal agencies, including the Departments of Transporation and Housing and Urban Development, to ensure that any new projects built with taxpayer dollars are able to withstand increasing risks of inland floods and, at the coast, sea level rise. Parts of the coastal U.S. have already seen more than a foot of sea level rise during the past century, and some models project another 3 feet of sea level rise by 2100.
Another climate adaptation initiative includes the formation of a task force of state and local officials to work with the federal government to make it easier for communities to invest in more resilient infrastructure, and amend or eliminate federal programs that provide incentives that increase vulnerability to weather and climate extremes. This may involve reforms to federal loan programs and disaster assistance funding. Already, the EPA is planning to integrate climate change considerations into some of its clean water funds and brownfields recovery programs.
The plan also includes provisions to help farmers prepare for and withstand climate change-related disruptions, including precipitation extremes, through the support of seven "regional climate hubs" in the Agriculture Department to provide climate information and related support to farmers.
In 2012, farmers in the Great Plains and Midwest endured one of the most intense droughts since the Dust Bowl-era, only to see flooding rains come a year later.
The Obama administration's action plan includes an “open climate data initiative” that would make climate data more readily available and applicable to the public and local officials, including the development of new sea level rise mapping tools that would allow people to better visualize the potential impacts of climate change on their lives. (A report from Climate Central in early 2012 produced just such a tool, called Surging Seas.)



The White House also plans to build on some of its notable energy and climate-related successes, such as the most stringent motor vehicle fuel economy standards in U.S. history. Those standards require passenger vehicles to have an average performance equivalent of 54.5 miles per gallon by 2025, which the White House claims will eliminate 6 billion metric tons of carbon pollution – more than the U.S. emits in an entire year.
The administration plans to work to enact post-2018 fuel economy standards for heavy duty trucks, buses, and vans, by working with the auto industry.
In addition, the White House is working with other nations, including China, to reduce emissions of non-CO2 greenhouse gases, such as hydrofluorocarbons, or HFCs, which are used as refrigerants but are powerful global-warming agents. The impact of phasing out HFCs by 2050 would be equivalent to the elimination of two years’ worth of greenhouse gas emissions from all sources, the White House said in a fact sheet accompanying its climate plan.
At the international level, the president is expected to announce an end to U.S. government support for public financing of new coal plants overseas, except for facilities deploying technology to capture and bury greenhouse gas emissions, or in poor countries where no other economically feasible alternative exists. For decades, the U.S. and multilateral development banks, such as the World Bank, have funded the construction of large, heavily polluting coal plants in developing countries in order to expand the availability of cheap and reliable electricity, despite the costs to the climate.
The administration's climate plan does not include a decision on whether to grant a permit for the controversial Keystone XL pipeline, which would carry Canadian tar sands oil from Alberta to the Gulf Coast. A White House official said that decision still rests with the State Department, and is "not yet ready for a decision."
