Global Climate Change Is A Fact

1326 words - 5 pages

Climate change, or global warming, has become a more prevalent issue in our society as the years pass by. Science is making great leaps and advances towards predicting future correlations between nature and human events. Many lines of evidence have been presented to the public to prove that climate change is and has been in progress for years now. The five most prevalent of these lines of evidence are: radiative forcings, climate models, correlations, observed changes in climate systems above the norm, and unnatural changes in the earths natural variation such as rising ocean temperatures and levels.
What are radiative forcings? As stated in the IPCC report of 2013, radiative forcings (RFs) quantify the changes in energy fluxes caused by changes in these drivers (natural and anthropogenic substances and processes that alter Earth’s energy budget) for 2011 relative to 1750. Positive RF leads to surface warming and negative RF leads to surface cooling. According to the data collected from numerous sources for the IPCC, the total radiative forcing is positive, which has led to a large uptake in energy by the climate systems. The largest known contributor to the positive total radiative forcings is caused by the increase in the atmospheric concentration of CO2, since 1750.
Climate models have been there to support the claims and theories of climate change. Climate models reproduce observed continental scale surface temperature patterns and trends over many decades, as reported by the IPCC, and have improved since the assessment report #4 (AR4). These observations include those of rapid warming since the 20th century and cooling immediately following volcanic eruptions. Climate models are able to show us that although there was an observed period of cooling, it was only due to the high volcanic activity causing cooling, as well as the timing with the downward phase of the 11-year solar cycle. In the climate model above (Figure 1) surface temperature change from 1901-2012 was observed and derived from temperature trends obtained from a data set. This model shows an obvious global increase of at least 0.6˚C. We are likely to see increases in temperature everywhere, but if temperature were to increase 1˚ at the equator, it would increase 12˚ at the poles, showing us that climate change will not act equally around the world. Climate models have also been able to show the human influence on the atmosphere and the ocean (increased CO2 and temperatures). It has been concluded in the IPCC report that more than half of the observed increases in global temperature averages are due to anthropogenic increases in greenhouse gas emissions.
It can be said that there are many correlations between the increase of natural events and human actions. The planet we live on is quite amazing in the ways that is functions, such as the redistribution of heat through ocean currents. Recently the globe has been experiencing many changes, some of which...

Global Warming: Climate Change is Happening Now

1100 words - 4 pages I believe the world is being faced with a serious issue of global climate change due to the greenhouse effect. The greenhouse effect is a naturally occurring process in the Earth's atmosphere that warms the planet. Without the greenhouse effect, on average, the Earth's surface would be about 60oF colder. The greenhouse effect occurs when visible light from the sun passes through the atmosphere and is absorbed by the Earth's surface. Some of that

Introduction The aim of this report is to evaluate to what extent anthropogenic greenhouse gas emissions are responsible for recent global climate change (Karl and Trenberth, (2003), and to identify the main uncertainties associated with future climate modelling. These queries are firstly explored by analyzing the effects that natural causes such as solar volcanic eruptions and solar output have had on recent global climate. This is then
