surface. The End-Triassic extinction was caused when Pangaea split, which created substantial volcanic activity, filling the atmosphere with carbon dioxide, leading to global warming.

6. The four greenhouse gases that are being measured by the simulation are carbon dioxide, water vapor, methane, and nitrous oxide.
7. The average temperature in the "Today" simulation is 59-60F. Adding clouds appears to do little, maybe up one degree. In 1750, the average temperature was around quite a bit lower, around 53-54F. The gas levels are as follows:

is proof that the rapid cooling did exist and did last for one thousand years. This evidence shows that natural disasters can trigger global climate changes without human intervention. However, anthropogenic climate changes do occur.
For example, during the colonial times of the United States, the amount of deforestation that occurred thanks to the coming of new settlers, led to increased rainfall according to some historians. " . . . described a change in climatic conditions in the North American colonies, and linked this favorable change to the ongoing settlement that produced increased drainage and deforestation" (Storch, 2012, p. 268). Although there is no real example of anthropogenic climate changes because of the… Continue Reading...
As shown in Figure 1 above, the 10 warmest years over this 136-year range took place since 2000, and the warmest year on record was 2016 (Global climate change facts, 2017). Indeed, if current projections are accurate, the long-term effects of global warming will be catastrophic, including an increase of between 3 and… Continue Reading...
coastal forest in the region, it has also been burning the brunt of global climate change. For instance, torrential and unpredictable rainfalls, tenacious drought, and other extreme and devastating weather conditions have been ravaging some parts of the regions including Mozambique, Kenya and Tanzania. The effects of the climate change which is usually followed by flooding, dearth, loss of agricultural yields, cyclones, and coastal erosion, has made surviving here more difficult for both plant and animals in the forest. With the prediction of worse weather conditions ahead, it must be noted that more threats await these already imperiled inhabitants of the region (“Coastal… Continue Reading...
they are habitats for a huge portion of the world’s biodiversity and essential in global climate change (Addis, p.5). Ocean or marine biodiversity is recognized across the globe as an essential component of life not only in the oceans, but also on Earth. The Federal Ministry for Economic Cooperation and Development states that ocean or marine areas are key components of the Earth’s ecosystem to an extent that without them life on Earth would be difficult and relatively impossible in its current form (p.3). The significance of ocean or marine areas to life on Earth is attributable to their role in regulating the climate… Continue Reading...
