Based on the data gathered by the scientists, the temperature has been rising and the Earth is getting warmer compared to the climate from the past. More ice caps and glaciers are melting at a faster rate due to the increase in global temperature.

Climate change is the result of the rise in global temperature. This event causes unusual weather patterns which are harmful to the ecosystem, especially to many plant and animal species. When plants and animals are not able to adapt in these new climate conditions, they will die, thus a decline in biodiversity would occur. It becomes crucial and threatening if keystone species become extinct because it will cause an entire ecosystem to collapse. When this happens, the ecosystem services are affected.

To address global climate change, scientists have already conducted numerous researches to recognize the problem in the environment. They have gathered data to analyze the problem and causes. Using this powerful information, they continue to guide the people on how we can make changes in our ways and behaviors to reduce the effects of climate change.

Since there are already scientific data and evidence from the scientists and the awareness of most people, the government of all the nations must also make a move. The next action is to enforce international laws that protect and preserve our nature. In this way, this problem is taken seriously by all people. There are serious consequences if this problem is not addressed as soon as possible.

According to the climate models of scientists, the variable that affects the most in terms of the increase in the global temperature is the emission of greenhouse gases in the atmosphere. This is caused mostly by human activities such as deforestation, burning of fossil fuels, and pollution. During the current century, the temperature increase is somewhere between 0.3 to 1.7 degrees Celsius. If the greenhouse gas emission continues, the increase would be around 2.6 to 4.8 degrees Celsius in the next century.

The sea ice in the polar region affects global climate because the ice itself reflects the heat back into space, instead of absorbing it like what the sea water does. If the temperature in the polar region gets warm, the ice caps would start to melt. The melting would cause the sea levels to rise. If this happens, the ocean circulation and weather patterns are affected. If the ocean absorbs more heat from the solar radiation, the Earth would get warmer. This would result in abnormal climate conditions, such as stronger storms and hurricanes, and an increase in the acidity of the ocean.

According to scientists, the temperature increase at the present time is somewhere between 0.3 to 1.7 degrees Celsius. This increase was caused by human activities such as the burning of fossil fuels, deforestation, and pollution. These events result in the increase of carbon dioxide and other greenhouse gases in the atmosphere. If the greenhouse gas emission continues, more heat is trapped in the air, thus the increase would be around 2.6 to 4.8 degrees Celsius in the next century.

If the Earth gets warmer, it leads to climate change and the melting of ice caps. The melting would cause the sea levels to rise and an increase in the acidity of the ocean. If this happens, low-lying lands would sink, and the ocean circulation and weather patterns are affected. Stronger storms, hurricanes and other natural disturbances would devastate the ecosystem and human systems. If life-forms in their natural habitats can no longer sustain these new climate conditions, they are likely to become extinct.
