\chapter{Introducion}
\section{Motivation}
Climate change is causing a shift in the precipitation patterns and an
increase in the global mean temperature. In response to this the spatial
distribution of snow cover, and its corresponding depth, water equivalent
and melting factor are changing \cite{IPCC 2014}. This study will evaluate
the relationship between these variables, and the changes in precipitation
and temperature during the last 30 years, and then comment on what we might
expect in the years 2011-2100.

答案1
文件存在的问题.bib：
- 作者应该总是用单词 分隔
and。不是逗号，不是&。 - 我认为引用键中不能有空格，因此请使用
IPCC2014，而不是IPCC 2014。 - 您知道，大多数条目末尾都缺少括号。
¨Rubel 等人的引文中有一个额外内容。- 我认为不会导致错误，但是有一个
editor字段例如用于 IPCC2014。 - 您需要在
IPCC2007作者字段周围添加括号，因为它会被两次出现的 所混淆and，因此它会将其解析为三个作者。不过，我建议为该条目找到一个更好的作者。 - 例如
Giorgi，最好只在 周围使用括号CORDEX，而不是整个标题。其他条目也是如此。（参见评论来自 moveve以下。）
