Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of Mendelian genetics, one common hypothesis was blending inheritance. But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
I strongly believe that global warming is a phenomenon caused by human activities, which results in a raise in greenhouse gases in the atmosphere. The scientific panel studying climate change stated that the proof of a warming is clear and the human activity has been the major reason for the change. Global warming is the result of warming of earth and sea due to the increased concentration of greenhouse gases. The main cause of global warming is the human activities which emit greenhouse gas which is known as the greenhouse effect. When sunlight reaches the earth it is absorbed by the earth and warms it.
