Global climate change has positive and negative effects on marine and terrestrial ecosystems. The cause of global climate change is said to be because carbon dioxide is being emitted through the large scale burning of oil, coal and gas, with an additional contribution coming from clearing of tropical forests and woodlands which results in wildlife life destruction. The carbon dioxide traps heat from the sun in the earth's atmosphere and prevents it from being sent back out into space. The heat that stays trapped in the atmosphere causes the global temperature to increase. Globally, average temperatures are expected to increase between 1.5 to 6.1 degrees Celsius in the next hundred years.

These effects have been demonstrated mainly in controlled environments such as growth chambers, greenhouses, and plastic enclosures.
Higher levels of atmospheric CO2 also induce plants to close the small leaf openings known as stomatas through which CO2 is absorbed and water vapor is released. Thus, under CO2 enrichment crops may use less water even while they produce more carbohydrates. This dual effect will likely improve water-use efficiency. At the same time, associated climatic effects, such as higher temperatures, changes in rainfall and soil moisture, and increased frequencies of extreme meteorological events, could either enhance or negate potentially beneficial effects of enhanced atmospheric CO2 on crops. Meteorological Events such as hurricanes and heavy storms damage trees and hence reduce productivity. Droughts disrupt crop rotation, many plants are not adapted to such environments and are therefore unable to survive hence productivity is reduced.

For interior regions, there might be beneficial gains in agricultural production resulting from the indirect effects of a warmer climate and adequate precipitation, especially in higher latitudes across Canada and Russia. The increased carbon dioxide might also directly increase plant growth and productivity as well. In fact, this theory, known as the Carbon dioxide Fertilization Effect, has led some scientists to controversially suggest that the Greenhouse Effect
In chapter five, they begin the autopsy of Tutankhamen, this chapter digs into how old he at the time of his death and what the reason was behind his death. His mummy measured at 1.63 m long but considering the shrinkage from the mummification he was 1.67 m, 5 feet 7 inches, at the time of death. Derry determined that Tutankhamen's wisdom teeth were just beginning to push through his gum line. This discovery along with the study of the growth plates Tutankhamen died between the ages of eighteen and twenty-two. There were a few people that believed that he died as young as sixteen, Leek, and as old as twenty-seven, Harris, but most thought that Tutankhamen was eighteen years old when he died. Now, the more significant question, what caused him
2. Climate has a considerable impact on agricultural production. However, along with climate change, extreme weather tends to be more frequent and more intense that destructively affects framing. To diminish the effects of climate change, farmers in Australia take climate change adaptations; while in sub-Saharan Africa, climate information and early warning system are used, and farmers diversify their livelihoods and cropping practices that are less sensitive to climate.
As photosynthetic rates decrease, this greatly affects the growth and reproduction of the plants and therefore affecting crop abundance (Peterhansel and Maurino, 2011). However, crop abundance could largely be increased by decreasing or preventing photorespiration from occurring (Peterhansel and Maurino, 2011). Increasing amounts of CO2 while decreasing amounts of O2 can do this. Inhibiting photorespiration would free up more energy and enzymes that were being used to fix O2 to know fix CO2 instead (Peterhansel and Maurino, 2011). This would lead to an increase in carbon
More than half of the increase in carbon dioxide in the past 100 years is because of human activity. (Burning fossil fuels) In 2010, carbon dioxide levels were higher than they have been in over 650,000 years. The CO2 levels are the cause for the increase of the Earth’s temperature. Greenhouse gases produced by humans will continue to cause climate change in the atmosphere because carbon sinks cannot absorb all of them. Carbon sinks, in 2009, were only absorbing about half of the human produced greenhouse gases, while the other half remained in the atmosphere. According to computer models, increased levels of human produced greenhouse gases will cause global warming and other climate changes. Although the models are not certain of how much warming will occur/how the climate will be affected, they all
Secondly, different crops respond to climate differently as they depend on carbon dioxide, temperature, solar energy, and precipitation (Walthall et al. 2013). Each plant species do well at an optimum concentration of the above requirements. Therefore any alteration to these levels in the atmosphere will lead to a decline in crop yield or plants would adapt to the changes over time. Also, temperature and precipitation changes also lead to an increase in the number of dry days and hot nights (Hatfield et al. 2014). The increase in the number of dry days and hot nights has a devastating effect on crop and animal production.
Everyone talks about climate change and how the Earth is slowly deteriorating, but no one seems to have specific examples. In Linnea Saukko’s “How to Poison the Earth,” she does use specific examples of what is causing climate change. She uses satire with a hint of sarcasm in her essay. She gives the reader specific examples of how to poison the Earth, but not really wanting to poison the Earth. Gretel Ehrlich writes her essay, “Chronicles of Ice,” a little differently. She uses personal experiences of visiting a glacier and the way that it is falling apart to explain climate change. She uses detailed, sensory description to explain
Changes in CO2 are affecting us and our environment in many ways. the most predominant effect of carbon dioxide changes is on the weather and oceans. Unpredictable heat waves are occurring in unforeseen parts of the world (i.e. Europe) and global temperatures as a whole are rising. The rise in the temperatures can not only affect us but the flora and fauna around us. With hotter temperatures, some plants and animals may be unable to adjust which would result in a chain reaction. Heat is affecting the oceans as well and many long standing glaciers or ice shelves to melt and alter the oceans temperature, levels and salinity. These, resultantly, are causing disruptions to the thermohaline conveyor and are effecting islands or seaside town as the water level
Hypothesis- If excess carbon dioxide is added to plants’ environment/normal habitat, then the growth of those plants will increase exponentially.
Climate change is a rising issue of importance in our day and age, and one that is threatening our global society on many levels. In the past few decades, scientists have discovered that our planet’s climate has been changing at an alarming rate. The way in which we have changed the land to
Climate is the average condition of temperature, amount of water vapor in air that is humidity and rainfall that has persisted over years and centuries and millenniums. Does climate ever change? Yes! It had changed! Earth, when newly made, was hot and red! Eventually it cooled and biological life started. Then Ice age eclipsed whole of the Earth, with chilled winds blowing all over the place. Gradually, the climate again changed to normal. Then the question arises, “What is actually normal temperature?” It might be the range of level of mercury in which life can persist. The climate, therefore, has changed, starting from hot to normal to cold and then it began reversing
This produces the so-called greenhouse effect that prevents a drastic cooling of the Earth during the night. Increasing the amount of CO2 in the atmosphere reinforces this effect and is expected to result in a warming of the Earth's surface. Currently carbon dioxide is responsible for 57% of the global warming trend.
The Impact that agriculture has on climate change is one of the largest in the world. Climate effects temperature and water availability, weather extremes and flooding and changing CO2 levels in the atmosphere. All of this impacts a shift in crop production patterns across agro ecological zones.
Greenhouses are controlled environments for plants to grow in prime conditions. Greenhouses are designed to trap solar radiation to create a warmer environment for the plants and allow the plants to grow where they normally would not. The Earth has a natural greenhouse effect and is vital in supporting life. Greenhouse gases create a sort of barrier to trap some radiated energy. However, the drastic production of greenhouse gases increases this barrier and creates a warmer temperature for the planet [Nature 476.7358, 2011]. Destabilizing the greenhouse effect of the planet can lead to major consequences which has already occurred such as:
U.S. Conditions like Florida and other states with a high range of hot spells are perfect
