　气候变化正影响着我们生活的方方面面，像英国铁路部门就正面临着气候变化带来的种种挑战。  
　　Changes to the climate could pose a "serious threat" to the UK rail network, scientists have warned.

2 g8 }4 h, K# q/ p5 R* B$ k9 T　　Extreme weather events - wet winters and hot summers - are projected to become more common over the next 50 years as a result of global warming.

　　A new study, in the Quarterly Journal of Engineering Geology and Hydrogeology, predicts this could lead to more landslides and floods.

　　To reach their conclusions, scientists from the University of Southampton and Network Rail studied the number of landslides and floods that resulted in delays of more than eight hours to rail travel.

! Q$ `0 m; T0 L8 |2 h, y　　She added one of the most "at risk" areas was the south-east of England, because much of London's rail network is built on soft clay, which is particularly prone to landslides.

　　In a separate study by Network Rail, engineers concluded that half of the UK's 10,000km (6,000 miles) of railway cuttings and embankments were in "poor" or "marginal" condition, leaving them vulnerable to extreme weather events.

　　Earlier this year, eight people were injured when a train was derailed between Glasgow and Oban as a result of a landslide following heavy rain. In another recent incident, 40 tonnes of rock blocked a Dorset railway line resulting in major delays.
