Earth and Space Science: Global Warming
What is Global Warming?
Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth’s climate system and its related effects.
I chose Global Warming as my key point because I think it is very important for people to know the impacts that global warming can cause and that Global warming should be dwelt with, with serious action instead of with a little look at and deal with it later approach.
Real Life Application/Situation:
Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
Many species have been impacted by rising temperatures. For example, researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
The sea level has been rising more quickly over the last century.
Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
Precipitation (rain and snowfall) has increased across the globe, on average.
Some invasive species are thriving. For example, spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).
Hurricanes and other storms are likely to become stronger.
Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
Some diseases will spread, such as mosquito-borne malaria (and the 2016 resurgence of the Zika virus). Ecosystems will change: Some species will move farther north or become more successful; others won’t be able to move and could become extinct.
Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier. Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay.
He fears that if sea ice disappears, the polar bears will as well. Meaning that the only polar bears you will see are in zoos.
The two websites that I chose that help explain my key point are conserve-energy-future.com and livescience.com. I those these two websites because they both give clear understanding to what global warming is and that they both give warning to what will happen if this continues. These websites also give some pictures as to what the earth would look like if this continues. Livescience.com gives some documentaries as to what is happening around the world and it gives some explanation about how we can stop it.
The book that I used is called Global Warming by Bill Freedman, Laurie Duncan and K. Lee Lerner from gale. This book is very good at making my topic understandable because the book gives very clear knowledge to my key learning point. It gives pictures of what global warming has done to Earth so far. This book gives many definitions to all words that look very different or words that don’t make many sense.
Could there be Global Warming,
On such a lovely morning,
Or is it just a little lie,
To blind us as our people die.

Global Warming Effects: Global Warming is already affecting the human kind, plant and animals in number of ways through increased ocean levels, droughts and changed weather patterns. Global warming is well recognized by scientists around the world as a serious public health and environmental concern.
The globe is heating up. Both land and oceans are warmer now than record-keeping began in 1880, and temperatures are still ticking upward. This temperature rise, in a nutshell, is global warming. Here are the bare numbers, according to the National Oceanic and Atmospheric Administration (NOAA): Average surface temperatures rose a total of 1.71 degrees Fahrenheit (0.95 degrees Celsius) between 1880 and 2016.
