全球變暖的福利 花香濃九倍

Its most ardent advocates say that global warming is gradually ruining our parts of our planet.
環境保護者們在奔走相告，警告我們全球變暖會毀掉地球上的人居環境。

But the effects of the phenomenon might be felt more positively a little closer to home, after scientists claimed that it will make flowers smell sweeter.
不過全球變暖也許能在家門口產生更積極的效果，科學家發現，全球變暖會讓花兒聞起來更香。

Some flowers could give out a smell that is nine times more fragrant than they currently produce, according to a report.
一項研究報告指出，一些花朵會產生比當前濃烈九倍的香氣。

It says that a temperature increase of between 1C (34F) – 5C (41F) will vastly increase the ability of flowers to produce their sweet smells.
這項報告稱，當溫度上升1℃-5℃，花朵製造香氣的能力會大大增強。

The study suggests that plants are able to produce more terpenes – the chemicals that give them their smell - in hotter conditions.
這項研究指出，在更溫熱的氣候條件下，植物會製造出更多的萜烯 ——爲植物提供香氣的化學物質。

Despite the environmental risk linked to climate change, the effect on flowers could also help bee populations as the stronger smells make flowers easier to find and pollinate.
雖然氣候變化會導致環境惡化，但是它卻對植物產生多方面有益的影響，在植物的數量上，由於香氣更加濃郁，昆蟲將更容易找到花朵併爲花朵授粉。

It also found that the effect could be more significant in cooler countries such as the UK and would have a stong impact on fruit trees.
研究還發現，這種對植物的影響在英國這樣氣候溼冷的國家更爲明顯，對果樹的產量也會有很大影響。

Last year, experts from the Intergovernmental Panel On Climate Change warned the average global temperature had risen by 0.5C in 50 years.
去年，跨政府氣候變遷小組的專家指出，全球平均氣溫在50年內已經上升了0.5℃。

They predicted temperatures will increase by 3C over the next century, causing a rise in sea levels, flooding, disease outbreaks and mass migration of refugees.
他們預測到下個世紀，溫度還將上升3℃，海平面將會上升，造成洪水、瘟疫、流民遷徙等災害。

The researchers from the global ecology unit at the Autonomous University of Barcelona looked at a variety of plants, including holm oak, yellow fleabane, heather and Spanish broom.
來自巴塞羅那自治大學全球生態小組的研究者對多重植物進行了研究，包括麻櫟、黃菀、石南花和金雀花。

In the paper the researchers said: ‘The species with the highest increases in emissions were those with the lowest [fragrance] rates.’
在研究論著中，研究者說道：“香味釋放量增長最多的植物品種是之前釋放香氣最少的品種。”
