即時溫室氣體濃度計
大氣中的碳量已達到80萬年來最高。 我們看不見溫室氣體，所以很容易忽略大氣中的碳在迅速積累。
計數器上的數字，是根據麻省理工學院的科學家發明的碳測量方法。其中涵蓋了所有在京都和蒙特婁議定書内界定，臭氧和氣溶膠除外，共計24種不易散去、長期存留於空氣中的溫室氣體。目前在碳計數器上，大氣中長期存留于空氣中溫室氣體數量的讀數為3.64兆噸，每月增長約20億噸左右。碳計數器的即時顯示，是根據最新的測量數據來推算當前的數值。同時預測值會隨著每個月接收到的數據重新進行校正。
碳計數器本身為碳平衡－－以低風險的碳信用額度抵消其能源使用。而電子數字是使用40,960個低耗能的LED燈來顯示的。
數據也提供24小時網路查詢服務，網址為http://www.know-the-number.com

外來種的危害229年

鼠患為害229年 阿拉斯加鼠島鼠蹤絕跡 路透 更新日期:"2009/06/13 15:42"
（路透安克拉治12日電）美國阿拉斯加州鼠島（Rat Island）終於不見鼠蹤！229年前一艘日本船隻在阿留申群島（Aleutian）發生船難後，船上充斥的溝鼠便「移民」這個地處偏遠的小島，大量殘害當地鳥類。
美國魚類暨野生動物管理局（Fish and WildlifeService）表示，去年秋季，當局花了一週半的時間，出動懸掛吊桶的直昇機向鼠島空投毒鼠藥，如今溝鼠（Norway rat）不見蹤影，且有些鳥類重現小島。
鼠島自1780年以來一直鼠滿為患，美國聯邦政府和自然保育暨小島保護機構（Nature Conservancy andIsland Conservation）合作推動耗資250萬美元的滅鼠計畫，堪稱全球最野心勃勃的清除島上外來危害物種行動。
當地跡象顯示，數種鳥類，包括阿留申雁、雷鳥、遊隼和黑蠣鷸重新開始在這個面積10平方英里（26平方公里）的小島築巢。
安克拉治的魚類暨野生動物管理局發言人伍茲（Bruce Woods）表示，鼠島的溝鼠完全絕跡目前還言之過早，須再經2年監測才能確定永絕鼠患。中央社（翻譯）

6/8世界海洋日
2009 Theme: "one ocean, one climate, one future"
About the theme: We live on a blue planet, dominated by the ocean which covers 70% of its surface. The world’s ocean and climate are inextricably linked: the ocean plays a crucial role in maintaining the Earth's climate, and ocean life is vulnerable to climate change. Likewise, in our interconnected world, the ocean affects us and we affect the ocean. A healthy ocean helps to absorb excess carbon dioxide, provides jobs and food to people the world over, and regulates climate and temperature.
