this respect, he notes that currently, the world has more than seven billion people, and that every year, about 80 million individuals are added to the statistic. Attenborourgh (2009) notes that the world has a carrying capacity beyond which it cannot sustain a growing human population. Taking note of this factor, he believes that the way to go in respect of ensuring that the world remains sustainable is taking responsibility for our growth in populations such as by using contraceptives. This paper analyses Attenborourgh’s views in light of past studies and professional views.
Real Climate (2014) notes that there are several indications that human activities have contributed to the high levels of carbon dioxide in the environment. In this respect, he notes that over the last 15 decades, the concentrations of carbon dioxide on earth haves grown from about 280 to 380 ppm (parts per million). This state of affairs has come in place as a function of such activities as clearing and burning of forested land and burning fossil fuels which are commonplace events ever since the industrial revolution. The Royal Society (2014) concurs with Real Climate in regard to human contribution to climate change. The Society states that the concentration of carbon dioxide in the atmosphere has increased by more than 40% since the industrial revolution began, most of this rise having occurred since 1970. These levels are higher than have been seen in the last 650,000 years according to the Intergovernmental Panel on Climate Change (IPCC) (BBC 2007).
Some of the evidences that show that climate change is a reality today include the decline in Arctic sea ice and the increase in the average temperature of the earth (global warming). Worth noting is that the average temperature of the earth’s surface has increased by roughly 0.8 °C since 1900 (The Royal Society 2014). Although this figure seems small, experts are quick to warn on its significance on human life, flora and fauna.

The study explores some of the consequences of the inattention of the climate change literature, and especially the mainstream U.S.-based legal scholarship on climate change. Then it outlines some of the normative advantages of city-inclusive governance in the context of climate change regulation and some possible solutions to address the concerns addressed before.
The result of global warming in animals and on agriculture and the effect on human inhabitants is indeed frightening. The earth is already on warming periods even before human predominance. Based on studies, from 1000 AD until 1850 AD, the rising of earth temperature is caused by the changes in activities on the sun and some volcanic eruptions.
Peoples evidently observed the melting of the glaciers in the North Pole, the increase of sea level in tropical zones at an average rate of 1.8 [1.3 to 2.3]mm/yr since 1993 and the warming of the earth which affects the cycle of vegetation and farm life (Intergovernmental Panel on Climate Change, 2008).
Climate change can be due to: Natural variability – warming or cooling due to sun spot activity, solar radiation Human activity – burning of fossil gases into the atmosphere, causing enhanced greenhouse effect However, there is much debate about what causes climate change, and the UN Framework Convention on Climate Change refers to a change of climate that is attributed directly or indirectly to human activity that alters the global atmosphere.
There is glaring evidence to prove the rising temperature. This evidence includes the drastic changes in the weather and climate that sees the occurrence of intense floods, drought, rising sea levels, melting of icecaps, and the acidification of water bodies.
It is necessary that the energy demand and the population growth are assessed so as to make proper sustainability strategies. This is why the energy strategies meeting the worlds growing population demand are crucial undertakings that must be considered by the every nation.
The study has evaluated two different sources against the population simulations in two different times. The results clearly indicated that the precipitation variability hindered the overlap of larvae and plants, increasing larval mortality. The study concluded that climate change accelerated the extinction of the butterfly species.
