With the changing times it is predictable that the future will be faced with changed climate. Many scenarios in the climate change project that greenhouse gas concentrations will increase as time goes by. This will also lead to increase in the global temperatures. (IPCC 2007) The rates at which the temperatures in the earth will increase are still not yet known. This is due to the uncertainty of the future greenhouse gas, emissions from aerosols and the response of the earth to the conditions that are changing.
There are also natural influences like change in the sun and the volcanic activity which may affect the temperatures of the earth in the future. It is however hard to predict the degree of change because it is hard to predict the timing and the intensity of natural influences.
The future temperatures will not depend only on the direct effects of the influences of nature and mankind. The temperature change may also be due to the feedback in climate. They can either decrease or increase the direct effect. For example, a positive feedback that may arise from the warming is the increase in low clouds from increased evaporation. The addition of the low clouds could lead to thick clouds which will result to cooling of the climate hence decreasing the warming.
Some of the possible projections of the future temperature change are increase of the temperatures by 20 C. This is to happen by the end of the 21st century. There will be a difference in the warming of the land areas and the sea areas due to the ability of water to store heat.
(Botkin, 2010) In the energy sector it is slated that by 2050 the will be reduction in the emission of carbon dioxide, methane and other greenhouse gases to approximately 80% lower than it is now. This means that there should be enormous reinvention of the economy of the energy globally. If we fail to do so there is bound to arise a major catastrophe within the sector. To arrive at this major achievement there will have been better insulations, getting rid of the incandescent light tubes and inflation of the tires. There will be scaling of every energy source with low carbon production available at the moment; these include the wind, solar and the nuclear energy.
By 2050 solar power will be harnessed. This is a very essential source of energy and very economical because you only need to buy the gadget and install; minimal maintenance chargers are incurred and there is no production of carbon. Hydro power which is power generated from water will also be utilized which is also economical and environment friendly.
Biofuels which are beyond the ethanol technology will be common in these times. Other energy sources that should be fully operational in many countries are wind power, safer nuclear energy, geothermal energy and cleaner fossil fuels.
(Sperling, et al 1994) By 2050 it is projected that there will considerable improvements in the transport sector in many countries. The systems are expected to be safer. For instance in aircrafts it is estimated that the planes will have a skin for absorption, smoothing, conducting, cosmetic and reflective purposes. This will make them to be safer.
There will be alternative for fuel in the planes as well as the vehicles because the available sources are not able to cater for the fuel need by then. Electricity is most going to be a common alternative for most fuel needs of the transport machines
