The Earth's temperature has risen by about one degree Celsius since 1880. Why do some people think global warming isn't real? There are many signs of a hotter climate.

Some rabbits can't change their fur quickly enough and are at risk. 翻译：自1880年以来，地球气温上升了约1摄氏度。为什么有些人认为全球变暖不是真的？气候变暖有很多迹象。冰雪消融导致海平面上升。雨水减少导致树木难以生长。鱼类迁往更凉爽的地方。气温高时，雪来得晚。一些兔子无法迅速换毛，并处于危险之中。

Polar bears live in the cold Arctic. The frozen Arctic is their home and the ice is their hunting ground. A polar bear usually stands on the sea ice to hunt for seals when they come up for air. But the ice has started to melt earlier each year. As the ice melts, some polar bears have lost their homes. Homeless polar bears have to move from ice to land earlier and stay on land longer. They become very hungry because they can't find enough food. 翻译：北极熊生活在寒冷的北极。冰冻的北极是它们的家园，冰层是它们的狩猎场。当海豹浮出水面呼吸空气时，北极熊通常会站在浮冰上捕食海豹。但是，冰开始融化的时间一年比一年早。随着冰层的融化，一些北极熊失去了家园。无家可归的北极熊不得不更早地从冰上转移到陆地上，并在陆地上停留更长的时间。由于找不到足够的食物，它们变得非常饥饿。

The Arctic is at the top of the world. It is a huge ocean with frozen snow and ice all year round. Arctic animals like polar bears and arctic foxes usually have thick fur to keep energy in their body. One interesting fact is that many are as white as snow. That's how they save themselves. Sadly, as the Earth gets warmer, more and more ice is melting, and it has made some animals homeless. 翻译：北极位于世界的最顶端，是一个巨大的海洋，终年被冰雪覆盖。北极熊和北极狐等北极动物通常有着厚厚的皮毛，以保存体内的能量。有趣的是，它们中的许多动物像雪一样白，这样它们可以保护自己。遗憾的是，随着地球变暖，越来越多的冰正在融化，这使得一些动物无家可归。

Seals are an example of why sea ice matters. Mother seals usually put their babies on ice to feed them before they can hunt for food by themselves. However, as the ice melts more quickly, the first six weeks of the seals' lives are not in their hands any more. They have to get into the cold water earlier. They may not find enough food to eat. Moving ice makes it hard for them to come up for air. As a result, seals are in great danger. If we don't take action, we will let them down. 翻译：海豹就是一个说明浮冰为何重要的例子。海豹妈妈通常会把它们的幼崽放在冰上喂养，直到幼崽能够自己捕食。然而，随着冰层融化得越来越快，海豹生命的前六周不再由它们掌控。它们不得不更早地进入冰冷的海水中，可能无法找到足够的食物。漂移的冰块让它们很难浮出水面呼吸。因此，海豹的处境非常危险。如果我们不采取行动，就会让它们失望。
