Philippine Climate Change
Climate change is taking place at a rapid rate for the last fifty years (IPCC AR4). It has been observed that carbon emissions, greenhouse gas concentration accelerated by anthropogenic activity are the main cause of the Earth's warming. An average of 0.2 oC increase in temperature has been seen since the 1970s with 2% increase in precipitation observed for the last one hundred years (IPCC, 2007a). Based on climate change scenarios from the United Nations IPCC, increase in temperature will continue in the future on a larger scale. Biodiversity is at risk with the onset of rapid climate change and its effects may be aggravated by anthropogenic activities (Thomas et al, 2004). Species thrive in distinct environments brought by an area's climate …show more content…
Philippine climate can be classified according to four types largely based on the dry and wet seasons (Corona, 1920). Type I climate experiences rainfall from June to November with the rest of the year dry. Type II climate is characterized by predominant wet season year-round with increased rainfall during November to February. Dry season in a Type III area is from February to April. Type IV areas experience even rainfall all year. Climate change planning and projections are being done by government units with most research done by the Philippine Atmospheric, Geophysical and Astronomical Services (PAGASA). Data collected from 1951 to 2009 were used in establishing climate trends. Projections for 2020 and 2050 were done. Findings indicate that there will be an increase of 0.65ºC in the mean annual temperature ranging from 0.1ºC and 0.35ºC. Frequency of hotter temperatures, qualified as days exceeding 35ºC, will increase. There may also be increased dry days and heavy rainfall, especially in Luzon and Visayas (Cinco et al, …show more content…
For climate change projections, minimizing the impact of climate change on the natural environment through human activities is considered adaptation (Mawdsley et al, 2009). Adaptation will depend on the species' fitness to the environmental pressures it will undergo. Adaptive responses have been classified in three ways by Gienapp et al (2007): 1) Dispersal to more suitable regions, 2) adjustment to altered environments in the short term, called phenotypic plasticity (Bradshaw, 1965; Przybylo et al, 2000) and 3) changes in genetic composition. These responses will depend on the organizational level as individuals, species, populations, ecological networks and the ecosystem (Bellard et al,
Why Is The Brush Tail Possums Considered Microevolution?
713 Words | 3 PagesEnvironmental change plays an important role in evolution. When an environmental change occurs, it can be a physical or chemical change. It can also be a gradual process such as the formation of mountains, or it can be a rapid and unexpected change, such as a natural disaster. When changes in organism’s environments occur, they must adapt to their new environment, this can cause ample amounts of selective stress and pressure on organisms, causing some species to eventually die out, while other organisms strive and evolve to be better adapted to this change.
Pan-Canadian Climate Change
1180 Words | 5 PagesUnder the assessment and evaluation of current environment situation, the federal government have developed the Pan-Canadian Framework on Clean Growth and Climate Change and other collective actions to address climate change. Under the federal consideration of climate change, there exists four pillars including pricing carbon pollution, taking action in each sector of the economy, adapting to climate change and supporting clean technologies, innovation and job creation. As carbon pollution is the majority factor influencing climate in earth, much attention has been put on this area. In order to control the carbon pollution to climate, government will collaborate with the territories and indigenous people to assess the practice of carbon
Fox Squirrel Research Paper
828 Words | 4 PagesA good example are squirrels in the Northeastern United States. Fox squirrels(Scirus niger) and gray squirrels(S. carolinesis) although share similar habitats, the way they are distributed are quite different across the region(Derge and Yahner 355). Fox squirrels dwell more on the edges of forests, whereas gray squirrels tend to move inwards, also fox squirrels prefer habitats with smaller percentage of small shrubs versus habitat space(355). Another aspect Derge and Yahner would mention that has made the assemblage a success is the fact that the two species are possibly active during different parts of the day, so as not to impede on localized resources and
Dbq Essay On Climate Change
711 Words | 3 PagesPeople may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.
Annotated Bibliography: How Climate Change Is Affecting Our Planet
190 Words | 1 PagesAnnotated Bibliography: How Climate Change Is Affecting Our Planet Controversy statement: Climate change is been debated for over centuries now. People all around the world are taking action and reducing burning fossils to minimize the gasses in the atmosphere. Many people believe that climate change doesn't exists. But there are a lot of controversial topics that proves that climate change is real. In my opinion, climate change is slowly killing us and destroying our planet.

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.

When graphed, in both plots we notice a curve. This to correlates within the SAR theory in a small area. As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review.

Pollution Essay: The Effects Of Climate Change Toward The Environment
1719 Words | 7 PagesOne of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
