This of course then will put an end to any food shortage that may be occurring and provide a new sense of prosperity to countries throughout the world which have been struggling to survive. Many of the changes and effects listed above are already taking place today on a smaller scale of course. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. Amounts and patterns of precipitation are changing as well but only slightly in comparison to what has been predicted for the future.
Climate change is also resulting in more habitat fragmentation. As Arctic ice melts, polar bears are affected by increased shipping activities and a rise in opportunities for oil and gas development. (WWF,2017) As the Climate Changes Understanding causes and consequences of climate-related shifts in ecosystem functioning, as well as the role of focal species in these processes, is currently a dominant theme in ecology. In the Arctic, temperature has increased at a rate two to three times faster than at southerly latitudes (Post et al.,
Over the past few years the issue of climate change has become an extremely relevant issue in our society. It has large impacts on a lot of things including wildfires, droughts, and increasing temperatures, just to name a few. One fairly recent impact that climate change is having is on the skiing industry. This year alone we are seeing the massive effect that climate change is having. With increasing temperatures many ski resorts are having a hard time staying open.
Climate change is an adjustment of global weather and atmospheric conditions and its effects on all other areas of life. Scientists have known that the conditions on earth have a tendency to change over the past 650,000 years, however, not only are we experiencing a rate of change greater than ever before, it is also 95% likely that human activities are the origin of the problem. Scientists can gather evidence about past climates and the planet’s responses from ice cores, tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. From this information, it is calculated that current warming conditions are occurring approximately 10 times faster than ever. This fluctuation in temperatures has caused surface temperatures to rise, ice sheets to shrink, ocean levels to rise, and ocean acidification.
This is due to the thinning observed at glacier snouts. For information, global sea level are currently rising at rate about 3 mm per year, Davies (2014). Hence, the amount of higher sea level will not only depends on the glacier recession, temperature and warming of the ocean but also the dynamic behaviour of West Antartic Ice Sheet. It receives high snowfall and also contribute high tendency to melt, which receive more number of days above 0℃ during summer months. Due to high temperature and thinning glacier, it will become thin and easy to diminish which make more easier to float.
According, to the Sanford Solar Center(SSC), The average global temperatures will increase by 2.5-10.4º F by the end of the 21st century. Sounds like no big deal rigt but SSC stated "The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC." Because of our actions will result in more hot days, which leads to Warmer ocean water, changes in precipitation, intense and frequent tropical storms and hurricanes and other weather patterns. Warmer climates causes sea levels to increase. The next century, melting glaciers and expanding seawater will affect wildlife that cannot survive in hotter environments. They may become extinct.
The climate for the past almost 2 decades has not significantly been increasing, however the climate has increased since 1990 by about 0.34 degrees Celsius. This warming and the warming of the oceans is believed to be the cause for the decline in Arctic sea ice, however the sea ice in Antarctica has been increasing so it is uncertain why sea ice levels continue to decline at such a fast rate. Carbon dioxide has increased since 1960 and is projected to continue will the world going through development and yes temperature has risen with carbon dioxide levels but it is not accurate to say that the
Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006). Warmer temperatures have led to increased melting of glaciers and sea ice, and shortening of
Canadians Combatting Climate Change Climate change, produced by global warming, is the natural fluctuations in global or regional climate patterns. Global warming affecting this would primarily alter the Earth’s weather patterns to lead into numerous consequences. This worsening issue has affected numerous regions of the world with bizarre events and catastrophes ranging throughout the entire world. Among these regions, Canada is one that is often affected with its Arctic Circle and colder regions altered by the heat of the Earth, what’s worse is the fact that the temperature is also rising. From 1948 to 2013, the average annual temperature of Canada has raised by 1.6 °C (Government of Canada, 2015) with the temperature affecting other factors
Unit 1- Activity 4: Paraphrasing Paraphrasing exercise: The temperature of the earth is controlled by the cold waters of Antarctica and the warm waters of the tropics. The rising of Antarctica's water cools not only other seawater, but also the air. Now, humans have begun to disrupt this natural occurrence through global warming and pollution.
