請從每一個我開始,並鼓勵您的所有親友一起投入抗暖化行動吧!

你我他都能做到的抗暖化錦囊

聯合國統計司資料,全球二氧化碳 10大元兇依序為美國、中國、俄羅斯、印度、日本、德國、加拿大和英國、南韓、義大利。

以排放總量排名,台灣居第 22位,但以人均排放量計,台灣高居全球第3名(11.9 公噸或12公噸),僅次於美國(19.9公噸)和澳洲( 19.4公噸)。
這不是台灣驕傲,而是全球危機。

在氣候變遷下的未來,預測 2050年左右,阿爾卑斯山上的滑雪聖地有70﹪不再有雪可滑 ;

世界最大的珊瑚族群大堡礁,可能在 2100 年之前消失,同時間台灣包括台北盆地內的台北車站、國父紀念館,甚至101 大樓 4樓將完全淹沒,而中國北京將被沙塵暴掩埋。

抗暖,是人類的第三次世界大戰,你我他都不能幸免!以下抗暖化錦囊由國家地理頻道提供,請從當下開始力行吧!

一、 下班電腦關機,一台電腦持續開一整晚,消耗的能源可列印一萬張資料。

二、 每使用一公升汽油,會產生 2.4公斤二氧化碳。而撘乘大眾運輸系統使用的燃料,每 1.6公里只有汽車消耗量一半左右。

三、 隨時保持輪胎在充氣狀態,能減少 6﹪汽油消耗。定期保養引擎,能減少 15 ﹪至50 ﹪汽油消耗。

四、 手機充好電,立刻拔掉充電器插頭,只要全球 10﹪行動電話使用者做到,省下的能源,相當於 6萬戶歐洲家庭耗電量。

五、 每天煮東西加鍋蓋,所需要的能源消耗量能減少多達 90﹪。

六、 只要回收一公噸重的紙,就能節約:17 棵樹; 2桶油;足以供應一戶人家 5個月所需的電力;或減少 25公斤的空氣污染。

I found an interesting experiment about greenhouse effect(溫室效應)

*****************************
The Earth's climate has changed many times in the past. Subtropical forests have spread from the south into more temperate (or milder, cooler climates) areas. Millions of years later, ice sheets spread from the north covering much of the northern United States, Europe and Asia with great glaciers. Today, nearly all scientists believe human beings are changing the climate. How can that be?

Over the past few centuries, people have been burning more amounts of fuels such as wood, coal, oil, natural gas and 5.gasoline. The gases formed by the burning, such as carbon dioxide, are building up in the atmosphere. They act like greenhouse glass. The result, experts believe, is that the Earth heating up and undergoing global warming. How can you show the greenhouse effect?


1.Two identical glass jars
2.4 cups cold water
3.10 ice cubes
4.One clear plastic bag
5.Thermometer


1.Take two identical glass jars each containing 2 cups of cold water.
2.Add 5 ice cubes to each jar.
3.Wrap one in a plastic bag (this is the greenhouse glass).
4.Leave both jars in the sun for one hour.
5.Measure the temperature of the water in each jar.

In bright sunshine, the air inside a greenhouse becomes warm. The greenhouse glass lets in the sun's light energy and some of its heat energy. This heat builds up inside the greenhouse. You just showed a small greenhouse effect. What could happen if this greenhouse effect changed the Earth's climate?

Another version of a greenhouse is what happens inside an automobile parked in the sun. The sun's light and heat gets into the vehicle and is trapped inside, like the plastic bag around the jar. The temperature inside a car can get over 120 degrees Fahrenheit (49 degrees Celsius).

[ 溫暖化](Global Warming)的成因?

  在自然界規律的運作之下,地球的大氣層中含有適量的溫室氣體,使得我們的環境舒適且適宜人居。但是,由於人類經濟活動的快速成長,製造了太多的化學品及空氣污染物,尤其是大量化石燃料燃燒所產生的二氧化碳(CO2)。這些污染物排放進入大氣,改變了大氣的組成,溫室氣體含量增加了,使得地表所釋出之長波輻射難以逃離我們的大氣層而逸散到外太空。越來越多的熱量蓄積在地表,造成不正常的人為溫室效應,而使地球表面溫度逐漸升高。

  在太陽系中,金星是溫室效應的典型代表,除了因為距離太陽較近外,它的大氣壓力為地球的9 0 倍,其中又以二氧化碳的含量最多( 9 6 % ),溫室效應嚴重,導致表面溫度高達4 8 0 ℃!相信你我都不希望我們的地球未來會變成這樣吧?

PS:480 degree? me faint.

there r more than the above reasons resulting the global warming, like the hair spray / air conditioner / refrigerator ...

pay a little attention, do a little more than u want, this tiny and old earth needs helps and we all can help, no matter how little, it counts.

对照这6条,我能做到的有:
1.及时关电脑,这点要努力改正,经常没关机就跑出去玩,
2.这条很容易做到而且我一直都在做到,因为我没有车
3.同上
4.已经做到了
5.做不到,因为我没有自己做饭
6.不知搞清洁的阿姨把我扔的纸回收没有,不过我平常很少用纸了写东西了,
除了练练画画之外
