What is global warming? What causes climate change? Since humans started using the Earth's resources in more incredible and wonderful ways we've seen a rise in global temperatures and changes to weather patterns that could have drastic consequences for future generations - but how much of this is due to the lives we lead today is still heavily debated. With rising sea levels and greenhouse gases increasing, one thing is for certain - the environmental impact of climate change can be felt today.
Rising sea levels is one of the most worrying consequences of global warming, threatening over 100 million people living in vulnerable coastal areas. But measuring the rate of the rise is fraught with difficulty.
We're all aware of some of the more publicised impacts of global warming: rising sea levels, extreme weather events, retreating glaciers. But amongst the despair there may be one small ray of hope: tiny horses.
