MY課題(全球氣溫變暖)

1、1為何選擇此現(xiàn)象或問題進(jìn)行調(diào)查，該問題或現(xiàn)象解決又有何實(shí)際意義或應(yīng)用價(jià)值結(jié)果顯而易見，全球變暖是不爭(zhēng)的事實(shí)。這不僅僅是一個(gè)環(huán)境問題。它影響我們的公共健康和國(guó)家安全。這是一個(gè)緊迫的問題我們每個(gè)生存在這個(gè)星球上的人-最緊迫的當(dāng)是如今人類所面臨的威脅。這將采取行動(dòng)，從你和我們大家的共同努力中。全球變暖不是主觀臆斷，它是科學(xué)事實(shí)，科學(xué)家告訴我們?nèi)祟惢顒?dòng)已經(jīng)對(duì)我們賴以生存和生活安樂的星球產(chǎn)生巨大的影響世界領(lǐng)先的科技期刊報(bào)告說，冰川融化以十倍的速度上升可能超過先前預(yù)期，即大氣中的溫室氣體已經(jīng)達(dá)到的水平?jīng)]有看到了數(shù)百萬年之久，而且物種的消失是由于氣候變化的影響。他們還報(bào)告了極端天氣事件，長(zhǎng)期干旱，海平面上升

2、。幸運(yùn)的是，科學(xué)還告訴我們此刻我們還可以作出重大的彌補(bǔ)，試圖扭轉(zhuǎn)這些影響，但只有通過立即采取行動(dòng)。這就是為什么我們研究這個(gè)課題希望大家一起加入遏制全球氣溫變暖行列。遏制全球變暖只是一個(gè)課題，但其目的卻是真實(shí)的。希望通過眾人的傳播與身邊的人們一起，迫使那些無意識(shí)的人們關(guān)注，團(tuán)結(jié)起來為世界出一份力。地球作為一個(gè)生態(tài)系統(tǒng)正在發(fā)生變化，很大程度上的原因是在于全球化的影響和人為因素。更多的二氧化碳排放于大氣層現(xiàn)在已經(jīng)比過去六十五萬年。這種碳在大氣中停留，就像是溫暖的毛毯，并擁有在熱-因此得名全球變暖。 我們存在于這個(gè)星球上的原因，是因?yàn)榈厍虻淖匀唤缣峁┪覀冏銐驘峥諝?，其中的溫度保持在一個(gè)非常狹窄的范圍內(nèi)

3、這創(chuàng)造了讓我們可吸入的空氣，干凈的水，以及氣候這一切決定了我們生存于此的條件。但是，這種平衡的打破已開始提示人類。我們超負(fù)荷的生產(chǎn)力大量的溫室氣體從我們的汽車，工廠和電廠被排向大氣。如果我們不開始解決目前這一問題，我們正在對(duì)我們的環(huán)境做毀滅性的變化。我們將體驗(yàn)極端溫度，海平面上升和風(fēng)暴吹襲難以想象的破壞。最近，令人震驚的事件，是符合科學(xué)預(yù)測(cè)氣候變化的影響的，這一切已經(jīng)變得越來越普遍。正因?yàn)槎鄶?shù)人都認(rèn)為世界問題，環(huán)境問題與之無關(guān)。所以，當(dāng)面對(duì)這一切的時(shí)候都處于漠然的態(tài)度。更多人卻仍然毫無意識(shí)肆意的破壞著這已奄奄一息地我們賴以生存的地球。所以我們呼吁，身為當(dāng)代大學(xué)生，受到各方面知識(shí)普及的我們，為我

5、我們也正為這全球變暖做著一份貢獻(xiàn)，雖然只是短短的一小時(shí)卻節(jié)省了 電，而 卻可以產(chǎn)生 熱。而我們要做的不只是一小時(shí)，是生活中的每一天每一刻。2你們是如何調(diào)查研究，采用何種方法，簡(jiǎn)單的說明調(diào)查研究的過程 04年6月11日在自然雜志上公布的一項(xiàng)研究結(jié)果表明,隨著溫室氣體的增加,亞馬遜雨林最深處的樹種結(jié)構(gòu)發(fā)生了顯著的變化全球變暖可使熱帶雨林變草原雨林消失全球變暖導(dǎo)致花期提前動(dòng)物北遷2004年11月11日發(fā)表于自然氣候變暖導(dǎo)致真菌流行病蔓延2006年1月12日援引最新一期英國(guó)自然雜志發(fā)表Learn MoreThe results are in and the reality of global warm
