Global warming is the most worrying problem on the planet.Global is the process in which heat from the sun is trapped in the earth’s atmosphere as a result of pollution.Scientists think that the Earth’s surface temperature has risen 1 degree Fahrenheit over the last 100 years.One degree over many years may not seem like much, but global warming can be devastating to our planet. Arctic sea ice is melting earlier and forming later.Glaciers are disappearing.Heat waves, storms and floods are becoming more extreme.Insects are emerging sooner and flowers are blooming earlier.In some places, birds are laying eggs before they’re expected and bears have stopped hibernating. When the world’s temperatures get warmer, a few things happen:the water cycle speeds up, causing more rain, droughts, wildfires and extreme heat waves.There will be more greenhouse gases in the air, as the atmosphere reaches capacity of how many gases it can absorb.Arctic ice will melt sooner and faster and won’t be as thick or expensive when it reforms.The oceans will warm and cause sea levels to rise more quickly, which can cause flooding on land and water contamination. If scientists are right, each one of us is at least a little bit responsible for global warming.So each of us has to decide what we’re going to do about it, and what kind of world we want to live in. No matter what changes lie ahead, our planet isn’t going anywhere.And neither we are.But what we do now could have a big effect on what our lives could be like in the near future.
