Essay On the CLimate change
Humanity's largest effect on local climate is likely to have resulted from land use, irrigation, deforestion and agriculture fundamentally change the environment.Marine mammals are also affected because of the greenhouse gases released out which is the main cause of global warming. This will change the climate underneath the water. Marine mammals have evolved to live in the ocean, but the effects of climate change may be altering primary product their habitat more rapidly than they can adapt to the changes.
Remains of beetles can be found in the sea, this is because climate change made the beetles unable to adapt to the climate, evantually the beetles die in the sea.
Climate changes can be caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities.Fossil fuels, aerosols and cement manufacture are the main cause of climate changes.
A single eruption of the kind that occurs several times per century can affect climate, causing cooling for a period of a few years. For example, the eruption of Mount Pinatubo in 1991 affected climate substantially. Huge eruptions, known as large igneous provinces, occur only a few times every hundred million years, but can reshape climate for millions of years and cause mass extinctions. Initially, scientists thought that the dust emitted into the atmosphere from large volcanic eruptions was responsible for the cooling by partially blocking the transmission of solar radiation to the Earth's surface. However, measurements indicate that most of the dust thrown in the atmosphere returns to the Earth's surface within six months.
