Effect Of Climate Change On Marine Mammals

All over the world there is a subject that has an effect on us all, and that subject has come to be known as climate change, or more commonly global warming. Climate change has a huge impact on Sea Turtles and their nesting grounds. Specifically referring to the Sea Turtle’s ability to reproduce. Especially within the last ten to fifteen years.

This study directly relates to my question because it provides two consequences of climate change; sea ice reduction and increase in primary productivity due to the warming of the oceans. As to how it is effecting the polar bears reproduction, results show that in one subpopulation's body size, condition, and reproductive success increased or remained stable due to an increase their prey ringed seals, due to increase in productivity. In the other subpopulation, there was lower recruitment and an overall smaller body size of the bears with a location that had fewer periods of reduced ice and no significant increase in productivity. This suggests that climate change can improve reproductive success of polar bears in some locations and decrease in

Global warming is a gradual increase in the average temperature of the earth's and its oceans and a change that is believed to permanently changing the earth’s climate.

The ozone layer surrounding our earth is slowly getting thicker allowing heat to get through but not get out this is a major concern as the world’s temperature carries on rising increasing the decline in ice. This is also drying up our water supplies making the world suffer.

Global warming is affecting oceans and seas, they temperature is increasing and is becoming higher the concentrations of carbon dioxide, making the oceans more acidic, Is impacting the coral reefs, the are at risk, there are dying, and important fact is that in 2050 is the global warming remain, the coral will die, including the animals that live in there. The oceans and seas are becoming worst, animals are dying for temperature or by the contamination that humans produce. Contamination effect to Global warming. The temperatures are becoming worse every year.

The ozone layer is in the Earth’s stratosphere and the necessity of this layer is to protect the Earth from the sun’s harmful ultraviolet radiation rays. “Since the late 1970s, an ozone hole has formed over Antarctica each austral spring (September / October), in which up to 66 percent of the total ozone is depleted” (Ozone Layer Protection). What directly causes holes in ozone are Chloroflourocarbons (CFCs), which rapidly damage the ozone layer. However, with the rising global warming temperature the CFCs’ process is catalysed, further damaging the ozone layer. “According to the estimates made by Dasgupta and Bhaumik (1995), it is likely that 10% decrease in ozone will lead to 20% increase in UV irradiance” (Gangul and Iyer 2006). Once an uncontrolled amount of UV radiation is exposed to lifeforms, especially to humans, “According to the estimates made by Vander Leun and De Gruijl (1993), 1% decrease in total stratospheric columnar ozone (SCO) will lead to 2.3% increase in non-melanoma skin cancer, 2% increase in cutaneous melanoma and 0.5% increase in the incidence of cataracts” (Gangul and Iyer 2006). More devastating effects from the depleting ozone layer are more destruction to agricultural fields, warming of oceans and increased acidity which is diminishing the amounts of phytoplankton, which can immensely affect the stability of the food chain. Therefore, the depletion of

Greenhouse gases in our atmosphere act almost like a blanket between the earth and frigid space. At lower levels, greenhouse gases trap some heat in our atmosphere

In 2008 the bears were listed by the U.S. Endangered Species Act due to global warming (1). This listing happened because of the ongoing loss of critical habitat for polar bears survival. The arctic sea ice sheets are the primary habitat for the bear. The bear lives, and hunts exclusively on these arctic ice sheets. Increasing global temperatures in the world’s oceans are shrinking the arctic ice for longer periods of time during the late summer months, leaving polar bears with limited hunting and breeding

Since late 1800s earth's average temperatures worldwide has risen by 1.4 degrees Fahrenheit. Global warming is gradual heating of the earth's surface, oceans and atmosphere. We are causing the global warming by burning fossil fuels such as oil, coal, and natural gas this fuel are used in factory and other places. Global warming has dramatic effect on wildlife animals such as polar bears, penguins, turtle and many other animals. Today we are going talk about the global warming effect on polar bears. The polar bear was listed as a threatened species.

Global warming has effected the world. The earth has had a drastic and devastating aftermath since humans have decided to release greenhouse gases into the atmosphere. This resulted in the ground (above or below water) temperature to rise; the very definition of global warming. This has warmed up the waters and the fish of the ocean are now living in an environment that is too hot for them to live in.

Global warming is the name given to the increase in the earth’s surface temperature. It is caused by the collection of greenhouse gases, carbon

Reviews provided by top organization, Intergovernmental Panel on Climate Change indicate that climate change is likely to induce changes in temperatures and adjustment associated with ocean circulation, sea level, and ice coverage. Impact of climate change on marine mammals occur differently according to type of mammal and its dwelling place either deep-sea dweller or surface sea dwellers (Aguirre, Ostfeld, & Daszak, 2012). Marine species distribution is affected by multiple factors; ecological, habitat related and anthropogenic factors. Habitat distributed

The Troposphere is the lowest layer from Earth of Earth’s atmosphere. In the troposphere is where all weather takes place. The second layer is the Stratosphere which has warmer layers than most of the atmosphere. The Mesosphere is the third layer of Earth’s atmosphere. In this layer temperature decreases with altitude. It also includes the coldest places on Earth. The next layer is the Ozone. In the Ozone layer gases and chemicals protect us from harmful Uv radiation from the sun. The last and final layer of the atmosphere is the Thermosphere. In the Thermosphere Uv radiation is captured by the sun and warms up this layer. This is the warmest layer of all of Earth’s atmosphere. Also in this layer radio waves are refracted due to the solar radiation interfering with

Much like the glass of a greenhouse, gases in our atmosphere sustain life on Earth by trapping the sun 's heat. The Earth’s atmosphere contains several different gases that act like a blanket, keeping the Earth warm. Water vapour and some trace gases like CO2, CH4 (methane), O3 (ozone), N2O (nitrous oxide), are “IR active”, i.e. they absorb heat energy, and stop the warmth from escaping into space. Without the entrapment of heat, the earth’s mean temperature would be -180 C and life, as we know it today, would not be possible. These gases are present in the atmosphere in tiny quantities compared to the amounts of oxygen and nitrogen. But even a small change in the concentration of these gases may create an effect that could change our

Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
