Scientific Agreement On Climate Change

The world is warming because of the increase in greenhouse gas emissions. Measurements show that greenhouse gas concentrations in the atmosphere are well above levels observed for thousands of years. Further global climate change is expected and the effects are expected to increase as time goes by. Reducing the future effects of climate change will require a substantial reduction in greenhouse gas emissions. [63] “The warming of the climate system is clear and, since the 1950s, many observed changes have been unprecedented for decades to millennia. The atmosphere and the sea warmed, the amount of snow and ice decreased and sea levels rose. 13 “Human influence on the climate system is clear, and the latest anthropogenic greenhouse gas emissions are the highest in history. Recent climate change has had a significant impact on human and natural systems. 14 In May 2011, the American Society of Agronomy (ASA), the CSSA (CSSA) and the Soil Science Society of America (SSSA) adopted a common position on climate change with regard to agriculture: an important aspect of this debate is that we are trying to define a single figure in order to present a number of opinions that have many nuances. First, as Oreskes says, “it is often difficult to determine what the authors of the paper think about global climate change.” In addition, published surveys differ in methodology. They do not ask the same questions in the same format, are grouped by different sampling methods and evaluated by different people who may be prejudiced.

These topics are the subject of much discussion in the literature on climate change, including in the articles we are debating here. Over the past century, there has been a rapidly growing world population and much more intensive use of resources, resulting in a sharp increase in emissions of gases such as carbon dioxide and methane, the burning of fossil fuels (oil, gas and coal), agriculture, cement production and deforestation. The geological record corresponds to physics, which shows that the addition of large amounts of carbon dioxide into the atmosphere warms the world and at: higher sea level and low-lying flooding; Highly modified precipitation patterns; High ocean acidity; and reduced the oxygen content of seawater. There is now concern that the earth`s climate will become more warming, not only because of the lingering effects of the carbon already added to the system, but also because of other additions, as the human population continues to grow.
