The Earth is dangerous place than ever. The reports of natural disaster occurring constantly with intensity. We, the human beings are the one that changed the world. This creates a situation in which ordinary events like earthquakes and hurricanes become increasingly elevated to the level of natural disasters that cause heavy losses in human life and property. The earth is warming. Earth’s average temperature has risen by 1.4F over the past century. This has affected the worlds climate and the ecosystem we live. Many places have seen changes in rainfall, resulting more floods, drought, or intense rain as well as more frequent and severe heat waves. Oceans are warming and becoming more acidic, ice caps are melting and the sea levels are rising.
Why is this happening? There are several causes of climate change, such as biotic processes, variation in solar radiation received by earth, plate tectonics and volcano

Once it dissolves in the ocean, carbon dioxide reacts with sea water to form carbonic acid. As people put more carbon dioxide into the atmosphere, the oceans absorb some of this extra carbon dioxide, which leads to more carbonic acid. An increasingly acidic ocean can have negative effects on marine life, such as coral reefs.Although some forests may derive near-term benefits from an extended growing season, climate change is also expected to encourage wildfires by extending the length of the summer fire season. Longer periods of hot weather could stress trees, and make them more susceptible to wildfires, insect damage, and disease. Climate change has likely already increased the size and number of forest fires, insect outbreaks, and tree deaths, particularly in Alaska and the West. The area burned in western U.S. forests from 1987 to 2003 is almost seven times larger than the area burned from 1970 to 1986. In the last 30 years, the length of the wildfire season in the West has increased by 78
This paper will investigate the role of forest health and climate change in changing fire behavior. The paper will explore how human impact has changed fire, and what measures scientists, managers, and practitioners can take to reverse the damage and bring the regions forests back to more
Changes occurring in the sun itself can affect the climate change on Earth. The intensity of the sunlight reaching the Earth can cause either warming or cooling. The sun flows a natural 11 year cycle of small ups and downs in intensity, but the effect of it on the Earth’s climate is negligible. However, over the past years, the sun’s intensity has been lower than the mid 20th century, and therefore does not explain the recent warming of the Earth. • Also
Running states “Warmer temperatures appear to be increasing the duration and intensity of the wildfire season in the western United States” (Running 927). The reason how rise in temperature would lead to wildfires is due to high temperatures creating less snowpack in the Mountain ranges. Less snowpack in the mountain leads to less runoff and more drought and dry conditions for the lower elevations. Running goes to to estimate that “snowpacks are melting 1 to 4 weeks earlier than it did 50 years ago” (Running 927) For Mojave Desert specifically it is the Sierra Nevada Mountain range that is receiving less snowpack and contributing to the perpetual drought conditions of this area. And with drought, high temperatures, low water and comes dry, flammable vegetation creating the perfect combination for
Population growth has continued to grow and people have continued to use up the earth’s resources. Climate change is an issue caused by humans and their disregard for the planet. Humans have used up so much of the earth’s resources that it poses a threat to all things living. Animals are becoming extinct and their habitats are being lost. Humans need to expand and build more places to live because there is not enough space for everyone due to population growth.
Therefore these effects could be substantial. Scientists believe that the destruction of trees is a adding reason to the cause of global warming. Also the IPCC has estimated that if the climate rises 1.5 degrees celsius to 2.5 degrees celsius that 20% to 30% of plants would have high risks of extinction. The same would go for animals if the temperature continue to increase the same percentages of animals could face extinction as well. Now in the last 50 years heat waves, droughts, and flood have all increased.
He also said “Over the last decade fire deaths have increased by 30%, he said. ”(“America is still burning’: Fire departments are struggling to recruit as climate change and modern materials make the job deadlier than ever”). Wildfires have also been increasing in size, intensity, and duration due to climate change. “The standard line from the US Forest Service about the number of wildland firefighters in the agency has been 10,000 wildland firefighters nationwide, but in recent years they have been unable to fill all of their positions due to difficulties in recruitment and
In another article written by Amanda Macmillan summarizes the effects global warming has on nature due to the cause of overload of carbon dioxide and forest deforestation. First, the text states earth’s rising “temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes”, which is not good news for us living here on planet earth. And it doesn’t stop there-there are also the effects of global warming creating even more “intense allergy seasons”, and the frequent sea level rise happening around the world.obviously these problems are not convenient for us we shouldn’t ignore this any more change must come. Other major examples found on a website called livescience.com it states “heavier flooding and precipitation” will come in result of global warming, and over the last 100 years the global temp has gone up .4 degrees celsius. These stats might not seem like a lot but they are having drastic effects on our
It is evident since the advent of agriculture that human interaction has drastically altered the face of the earth. There is no doubt that human interaction is applying more and more pressure to the planet and to us humans as well, it is not only an issue of climate change. Drastic climate change can alter the world as we know it. Natural wonders, feats of humankind, and almost all infrastructure is threatened by the era we live in. In the modern age, we spend a great amount of time dedicated to discover the scope of the change humans have caused unto the Earth, it allows people to study patterns and possibilities while making observations.
Climate change is essentially a significant and long-term change for the statistical distribution of weather patterns over periods of time. Climate change is a change in the regular weather patterns such as more or fewer severe weather events. (Greenfleet, 2011) The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse gases affect identified. In the late 19th century, scientist first argued that human emissions of greenhouse gases could change the climate.
Texas was once a republic; hence, it has more history than other states. The Lone Star State has enough history to have a mandatory full-length class in high schools, colleges, and universities—not many other states could say the same. Cowboy hats, cowboy boots, and jeans remain the image that most people have when they imagine Texas, but Texas and Texans are beyond that. Furthermore, “Texas is the second largest state […and] the second most populous state” (Neilsen-Gammon 1). All throughout the distinct State of Texas, the weather significantly varies from one region to another; thus, more variations in the climatic zones exist than in other states.
When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Hot and dry conditions cause earth surface to be drier and this lead to massive wildfires which destroy wildlife habitat and inject huge amount of carbon dioxide into the atmosphere. There are some positive impacts of wildfires on the environment, wildfires clean up a forest of dead and decaying matter. They maintain ecosystem balance by removing diseased plants and harmful insects and regeneration of seeds through sunlight. They kill invasive species, allowing for indigenous species to continue thriving. Wildfires can engender flash flood conditions and enable soil erosion, with an increase in water runoff.
Homero Castro Ms. Cabaj English IV, 3rd period 12 February 2018 Global Warming Global Warming is affecting the entire world. The issue of global warming is important because it’s affecting everyone.
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
For example, the rises of sea levels, glaciers, and polar ice caps are melting; numerous animals are emigrating to find other places to exist; trees are in bloom sooner. Scientists have confirmed that the temperature will keep on rising up for the next decades because of human activities in the industry (Alina). One of the biggest problems facing us now is global warming. It not only affects animals and plants but also the human population, which is indeed scary (Markham).
