The effects of climate change have become more apparent than ever within the last 100 years. Increasing climates have been proven; with the warmest temperatures in 30 years being recorded (Houghton, 1994). Suggested cause of this increase is population change, the ever increasing demand for natural resources to sustain economic growth has resulted in exploitation of ecological systems at a rate never recorded before. These huge changes to the planet will have a knock on effect to individual and global ecosystems resulting in varying levels of positive feedback. Throughout this essay I will be discussing on various ways climate change effects the ecology of the planet.
The planet shows fluctuations of temperature from millions of years ago.

Evidence such as the rising of sea level by 17cm in the last century or the 150-250km3 loss of Greenland ice per year between 2002-2006 (NASA, 2014) proves that climate change is happening to us currently and the effects are immediate.
The Carbon Cycle consists of the vital components for all animal and plant lives. It is primarily a reflection on primary and secondary production (Krebs, 2009). As seen in Figure 2, carbon levels have not been constant throughout history. Figure 3 represents the basic components of the Carbon cycle. The diagram shows that the oceans are the largest sink of carbon, and is at a constant equilibrium of atmospheric CO2 and aqueous CO2. The increase in atmospheric CO2 levels causes ocean acidification by decreasing the pH of the oceans. PH values are said to have dropped by 0.1pH units since pre industrial levels and are expected to drop a further 0.3 units by the end of the 20th century (Scott C Doney, 2007). This chemical change will have knock on affects in many marine ecosystems, which will be discussed later.
However, there are positive results of the rapid increase of CO2 in relation to plants a; CO2 enrichment will no longer be a limiting factor of photosynthesis. Evidence of this is results from 3,586 separate
What is climate change exactly? Climate change happens when long-term weather problems occur. For example: global warming can be a part of climate change because the weather changes and the heat increase very slowly. Climate change is becoming a huge problem and is affecting the world's ecosystems and communities. The world could become one huge oven or it won't. Nobody knows.
An Introduction to Ecosystem Sustainability and Climate Change: Anthropogenic activities have been pouring greenhouse gases into the atmosphere which is evident from the increasing trends of changes in global temperature, precipitation, climate induced hazards/disasters, pest distribution, etc. It is alternating the habitable areas of species, their distribution, rate of survival and reproduction, food web interactions, ecosystem services, and their conservation. Ecological managers need to invent smart solutions to control and mitigate further erosion of ecosystems.
This increase in oceanic inorganic carbon has offset the seawater carbonate chemistry by causing increasing concentrations of CO2 and bicarbonate, while causing decreasing concentrations of carbonate and pH levels (Dedmer 2013). Rost and colleagues (2008) express that emissions of fossil fuel have caused an immense increase in the levels of atmospheric CO2, which are then deposited into the surface water of oceans. This increase in carbonic acid is in turn decreasing the pH balance, which poses a threat to marine organisms.
It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).
Before the industrial revolution, atmospheric CO2 was steady for at least 1,000 years.The anthropogenic CO2 emissions of 2010
The studies of Earth have shown that in the last hundred years, the temperature has gone up one degree Fahrenheit. Even just one degree can make a big difference to the Earth’s natural form. The warming of the Earth has caused the snow and ice to melt much faster and the ocean levels to rise. In the next hundred years the effects will be more severe.
Between present day and the beginning of the Industrial Revolution, the concentration of CO2 dissolved in our oceans has risen by more than 30% (1). This is because nature wants to exist in equilibrium (2), so our oceans are absorbing CO2 until the concentration of the molecule is the same or similar to that of the air around it. Since the amount of carbon dioxide in the air is increasing, the amount absorbed into the sea is increasing as well. Experts say that if the levels of CO2 continue to increase at a similar rate, the end of the century will sea the ocean 150% more acidic than pre-Industrial Revolution (2,7). These rates have not been seen in more than 20 million years (2,7).
Leading up to the present, levels of CO2 have fluctuated due to geochemical processes such suspension of the gas in sediment, silicate rock weathering, and volcanism. Also, human activity plays a large part in carbon deposition into the atmosphere predominantly through the burning of fossil fuels and the cultivation of livestock. On a drastically larger time-scale the carbon cycle is ever so slightly reducing atmospheric CO2 , which will ultimately bring the concentration down near zero, causing all life on the planet to be wiped out. The carbon cycle, including both terrestrial and aquatic processes, is the foundation under which photosynthesis is possible. Aside from the carbon cycle, CO2 is a key element in many other natural processes and phenomena such as the “Greenhouse Effect” and “Global Warming”.
Climate change means the fluctuation changes of the climate in a period of time, this period of time could means several decades or centenaries, the fluctuation could be regional or global. At present, what we talked most is the effect of the environment policy on the climate, in another words is the effect of human factor on the climate, especially the questions about the global warming, and climate change is one of the greatest challenges facing the world, it’s extremely urgent, people wonder that if the power of an individual can slow down the global warming, if we join with scientists, business enterprise and the government, start from small details, we can do a big contribution for the reduce of greenhouse gas emission.
Climate change has also had a negative impact on the aquatic life. For instance, fish normally thrive and reproduce in cool waters. Global warming results in a very high rise in temperatures; however, the effect is not normally felt since water covers more than two-thirds of the earth’s surface and therefore absorbs much of the rise in temperature. The Ocean temperatures have therefore risen to very high levels that are not conducive for reproduction of fish; this has resulted in a significant reduction in the population of fish species with others becoming extinct while others try to migrate to regions where ocean temperatures are lower (Harley et al., 2006). The reduction in the population of fish has resulted in a great imbalance in the ecosystem and food chain as other ocean creatures that would feed on fish have to look for other predators or also die.
In a world filled with seven billion people minding their own business, very few will take a second and look at the world around them and how it has been ravaged, even damaged beyond repair since our first evolutionary ancestors took their first few steps in this planet from being mere apes. Whole ecosystems, which used to flourish, are now nonexistent. Entire species of plants and animals, who used to dot the various landscapes of the world, are now nearly extinct if not already extinct. Greenhouse gases emitted from human activity has also resulted in a higher likelihood of extreme weather anomalies to occur due to the side effects of climate change on the planet (Buhaug, 2016). If drastic measures are not taken in due time,
In another matter, this is not the first time that climate change has affected the planet in the past there were many problems to the earth millions of years ago. There were five major ice ages from the longest and first scientists believe occurred was two point four to two point one billion years ago during the early Proterozoic Eon there was an ice age formed and it was the Huronian. The second ice age was the cryogenian and it has been known that it produced a snowball earth in which permanent sea ice extended to or very near the earth's equator; this period occurred from eight hundred and fifty to six hundred and thirty million years ago. The third ice age that occurred was the Andean-Saharan it occurred during the Paleozoic from fout
Anthropogenic CO2 release into the atmosphere has led to increasing temperatures in the atmosphere and in the ocean (CITA). Greater amounts of CO2 is causing the oceans to become more acidic (Caldeira & Wickett, 2003; Ross et al., 2011).
You have been bitten, that pesky mosquito flies away. You wait unaware of what’s about to happen. You begin to feel unwell, you 're fever rages as you begin to seize. You have Malaria but live in Europe. Climate change is classed as any alteration in global weather patterns over a period of time. However the climate change the earth is currently experiencing is far from anything ever experienced before and its 99% certain that it has been caused by human industrialisation. Like anything that affects the earth on a global scale it affects everything including microorganisms and therefore disease. Climate change is causing disease to spread and increase in severity. The main adverse effects causing the spread of disease from climate change is global warming, El Niño and human migration due to climate change.
The development of society and economy has caused varieties of environmental problems in the past decades. Carbon dioxide (CO2), the most common greenhouse gases has caused a great impact on climate change, and to reduce the emission of CO2 becomes a worldwide agenda. (Christopher R.I, 2013) While, Buildings, taking up third of the total UK greenhouse gas emissions (CCC, 2014http://www.theccc.org.uk/charts-data/ukemissions-by-sector/buildings/), have a great potential to reduce the greenhouse gas emissions and improve the sustainable development in the future. One of the non-neglect issue to reduce the energy use and CO2 emission of building is in the construction phases. The embodied carbon accounting 20-50% of the total
