![]() Many of these gases are greenhouse gasses, which cause the Greenhouse Effect (i.e., global warming and climate change). With these processes, there are by-products of many sorts including gas emissions such as carbon dioxide (CO2), methane, nitrous oxide, carbon sulphide, hydroflurocarbon (HFCs), and more. Since the industrial revolution, we have been producing energy for heating, building, manufacturing, transport, electricity, agriculture, living and waste, and more. There has been a rapid change in our climate across a very short period of time, since the industrial revolution in the 1750s. With more mouths to feed, we required more food, more technology and more changes in how we live. And we have been growing faster and faster in population ever since, with only a recent slowing of the population growth rate. With more food available, our population could increase. Homo sapiens (i.e., modern humans) invented agriculture about 10,000 years ago, which provided more access to food. Modern Humans have been around for about 200,000 years, with ancestors ranging back millions of years. More recently, within the past 650,000, there have been 7 cycles of glacial advance and retreat, with the end of the last Ice Age occurring about 11,700 years ago. ![]() Indeed the climate has continued to change since life first formed on earth approximately 4 billion years ago, following the formation of the oceans about 4.41 billion years ago. The Earth’s climate has been changing across its 4.54 billion year life-span. We will look at the training required of a scientist to be able to perform quality research that guides our understanding of our climate, and briefly look into the kinds of sources of information to trust on this issue. This extended blog will review a brief history of climate change and how the evolution of the human mind works against us through cognitive biases, when we attempt to understand climate change science, and the change required to curb global warming.
