تعطي قراءة آنية لجودته.. بالتعاون بين هيئة تطوير الرياض ورئاسة الأرصاد
تشغيل 15 محطة لمراقبة تلوث الهواء في العاصمة
تحسين نوعية الوقود من شأنه خفض التلوث البيئيالرياض - محمد الغنيم
تعمل الهيئة العليا لتطوير مدينة الرياض والرئاسة العامة للأرصاد وحماية البيئة على تفعيل مراقبة جودة الهواء في مدينة الرياض من خلال تشغيل وتركيب 15 محطة مراقبة في مواقع محددة تم تخصيصها في أرجاء المدينة حيث ستعطي قراءة آنية لحالة جودة الهواء في المدينة.
ويأتي ذلك ضمن البرنامج التنفيذي للتحكم بمصادر تلوث الهواء الذي يتضمن سلسلة من الإجراءات التي تقوم عليها الجهات المعنية للتحكم في مصادر تلوث ومن ذلك الخطة التي تقوم عليها وزارة البترول والثروة المعدنية من خلال شركة أرامكو لتحسين نوعية الوقود في المملكة لتتوافق مع المعايير العالمية.
وتقوم الهيئة في هذا المحور على برنامج إدارة جودة الهواء الذي يشمل بناء نموذج رياضي لمحاكاة حركة الملوثات وارتباطها بالمصادر وتطوير مؤشرات جودة الهواء في المدينة والاستفادة من قواعد المعلومات البيئية بما في ذلك استخدام نظم المعلومات الجغرافية GIS بالإضافة إلى تشغيل وصيانة نظام المراقبة الدائم الذي يشمل محطات المراقبة والنموذج الرياضي وقواعد المعلومات البيئية، وزيادة التوعية والعمل على تدريب المختصين حول هذه الأنظمة.

UN Climate Change Conference COP15
Copenhagen, Denmark, 7-18 December 2009
Copenhagen Accord marks first step towards legally binding global climate agreement
Copenhagen
Copenhagen… moved the process forward. British Prime Minister Gordon Brown said the agreement had almost universal support. “Let’s remember, a year ago nobody thought this sort of agreement was possible.” But most are not satisfied. Among the reasons for disappointment are that it is not a legally binding treaty. However - neither was Kyoto… initially
The Kyoto accord only became legally binding 9 years later in 2005, and only then because that was when Russia signed the agreement. The protocol had to be ratified by enough nations to account for at least 55% of greenhouse gas emissions in order to become a valid, binding treaty, and once Russia signed, that threshold was reached. And really it took from 1992, when the Rio agreement focused attention on the problem; till 2005 for it to become legal and binding. These things take time
The good news is that this time, unlike Kyoto, every nation is included. For the first time, China, India and the US were participants in a worldwide agreement that deep cuts in global emissions are required to hold the increase in average global temperatures to less than 2 C above the pre-Industrial Revolution level
The bad news is that this is not enough to save Tuvalu. Like the Maldives, they will be the first of us to go. If the entire world had agreed to the The U.N. Framework Convention on Climate Change in 1992 and acted swiftly, we might have. We needed to keep the average global temperature rise (average means add some snow in Texas plus even more drought in Australia = global average added together is still hotter) to no more than 1.5 degrees C to save Tuvalu
But it’s to be expected that there are losses. As the decades roll by and we don’t switch to clean renewable energy fast enough, it will get harder and harder to come out of these international agreements to do something about the problem, because less and less will be achievable..
EARTH PLANET
EARTH Is in danger, with so many people using so much we could use up our natural resources in a very short time.Not only do all living things depend on our natural resources, but each living thing in the food chain depends on the other to survive That's why it is important that we take care of our planet and everything in it

STOP GLOBAL WARMING
What is causing global warming
Scientists agree that the burning of fossil fuels like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees). Trees soak up carbon dioxide, one of the greenhouse gases, from the air
Global warming" refers to the increase of the Earth's average surface temperature, due to a build-up of greenhouse gases in the atmosphere. "Climate change" is a broader term that refers to long-term changes in climate, including average temperature and precipitation
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that become extinct (disappear completely) because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming
