Changing weather patterns spell doom for humanity because this, among other things, contributes to food insecurity and negatively impacts on economies which heavily rely on agriculture such as most of those on the African continent.
Climate change is defined as a long-term change in the statistical distribution of weather patterns over periods of time that range from decades to millions of years. It may be a change in the average weather conditions or in the distribution of weather events with respect to an average, for example, greater or fewer extreme weather events.
There are various causes of climate change which include greenhouse gas emissions, such as those emitted by the manufacturing and construction sector; generation of electricity and heating and the transport sector. There is burning of fossil fuels such as coal, oil and gas to support the various sectors. This burning of fossil fuels greatly increases the atmospheric concentration of greenhouse gases, trapping more of the sun’s energy near the Earth’s surface. In response, our planet is warming at an unprecedented rate and ecosystems such as forests and swamps are changing. Forests are steadily disappearing and swamps drying up.
