As earth entered a warming trend, mammals which were used to the cold could not survive but became extinct when glaciers retreated. Tundra gave way to lush thick forests and the animals who were once used to the cold climate could not adapt like the mammoth and the wooly rhinoceros. Humans who once hunted these animals now has to switch to smaller animals and then start to rely on gathering plants for food. The earth is currently in an interglacial period. What remains of the continental ice sheets are located in Greenland and Antarctic.
These problems are not going to fix themselves without help the plant will warm up 0.6 celsius without any greenhouse gases influence. According to meteorologists from 1890 to 1990 temperatures have risen 0.72 degrees fahrenheit to 1.26 degrees fahrenheit. In fact through the 20th century global temperatures have rises 1.4 degrees fahrenheit which could lead to surface temperatures increasing. There has been efforts to help with global warming considering from 1998 to 2009 $99 billion dollars have been spent on climate change. Therefore these effects could be substantial.
Global Warming is the most controversial issue that we face today, because throughout the years we have been releasing greenhouse gases that are harmful in the long run and will affect the future generations. The temperature throughout the twentieth century has been increasing steadily by 1.4 degrees Fahrenheit a year. The cause of global warming is from the release of gases called GreenHouse gasses such as carbon dioxide, methane and several more. Factories ,cars, and other working companies release these gases while extracting fossil fuel from the earth 's crust. Alternatives sources of energy can be implemented because if we keep on using energy that releases these GHG then we might tear up the ozone layer.
As the polar ice caps melt further toward the poles every summer, it makes the polar bears job of hunting and staying alive harder and then eventually, impossible. This creates an empty niche in the northern ecosystem. (Williams et. al. 2011) While making it difficult for the polar bears to hunt, shrinking ice caps make it easier for orcas to move further north and reach new food sources such as narwhal and seals.
Glaciers have an impact on the rise in sea level the glaciers melt and causes about .03 inch rise in the sea level per year this is equivalent to 571 trillion pounds of water! Glaciers are responsible for ⅔ of the sea level rising in almost a decade. If it continues it can and will lead to loss in homes, land, and beaches. And the rise if sea level is not just the glaciers, it’s also the ice sheets of Greenland and the ice sheets of Antarctica. If all the world 's glaciers would melt the sea would rise 24 inches, scientist speculate that Greenland’s and Antarctica 's ice sheets melt it has potential to raise sea level a little under 220 feet (66 meters.)
Global warming exists, and it is not only affecting the environment. Many, many animals are going endangered and even extinct because of human caused climate changing. One of those notable examples is the polar bears, which only have a population of 20,000-25,000. The reason polar bears are going extinct is because warmer temperatures in the north is causing the ice caps to melt more, and in the summer, polar bears use the ice caps to travel to get food after hibernating. But if the ice caps melt too much and break away, then polar bears
Ice cores also have to do with climate change when ice cores fluctuate the temperature rises leaving the mammoths in terrible conditions. So we are always weary if another ice age occurs. I think that another ice age will probably occur in a couple of centuries since the climate seems quite
It also evaluates the effectiveness of these solutions. Global warming is an issue that is not new to us. It has already warmed by 1.5 degrees Fahrenheit since 1900s ("Global Warming Is Happening Now"). Ecosystems are feeling the heat and are struggling to maintain their lives. It is easy to observe that the effect of global climate change on the Earth.
With continuous Ocean and atmospheric warming, sea levels will continue to rise at a higher rates than currently recorded this year. According to the NOAA tide data the sea rises Between 0.8 to 3.3 mm Per year with an average rate of 1.8 per year. Greenland and Antarctica together hold enough ice, that if it all melted sea levels would rise more than 80 meters. Rising tide data published by NOAA has suggested that low lying coastal areas will be affected the most by this problem. Places Like the low lying parts of the Netherlands, Brazil, Egypt, America, Japan, India, Indonesia, Vietnam and
Climate change has been a prevalent topic in our world for some time now and for good reasons. Global temperatures have not only risen twice as fast as fifty years ago, but have risen 1.3 degrees Fahrenheit since the nineteenth century. Some may say that this is a normal occurrence as the past has shown that the earth undergoes cooling and warming periods; but scientists were kind enough to provide a graph of average world temperatures in 2012 that proved otherwise. The chart showed that temperatures have remained relatively constant for several hundreds of years, but they have turned sharply upward during the last hundred becoming what is now known as the hockey stick graph (Central 1). This sharp curve has been carefully analyzed, and as one might have guessed the most logical and proven reasons for it is industrialization and the burning of fossil fuels.
Now here were are in the 21st century surrounded by all this technology and environmental resources. Are we going to trust these new found theories of the Anthropocene, or wait until it’s entirely too late? The devastation would be much worse, from polar ice caps melting to natural disasters. The sea level is rising at 0.14 inches per year due to global warming. (Scantron 4) Although that does not seem like a lot it adds up over several years; it is equivalent to a foot over a lifetime.
In 2014, the average amount of global carbon dioxide rose to 397.7 parts per million, and comparing that to the emissions of the year 1750 which was 278 million parts per million (Fleur 2). They are expecting the average amount of carbon dioxide in the atmosphere to surpass 400 million parts per million by 2016, which is less than a year away ( Fleur 1). Which if carbon dioxide reaches 560 parts per million it would cause water vapor and clouds in the atmosphere (Fleur 2). The amount of carbon dioxide does not just leave the atmosphere after being emitted into the air but about 900 parts per million will still be in the air after 100 years (Mooney 2). Now not only has carbon dioxide caused major problems in the atmosphere but also gases such as nitrous oxide, methane, greenhouse gases, and
