​​​​​​​Essay Example on Climate Change

The science of climate change is often wrapped up in a discussion on entropy and us, the human species. How will our current population set the stage for the next hundred years? Overflowing rivers are one of the threats expected to threaten human survival in the future. Humans are disproportionately impacted by the changing climate. While scientists warned us of the potential repercussions of global warming, now, populations are being displaced because of larger, yet more frequent floods. Anthropogenic global warming, the burning of fossil fuels, and population change are teamed to create a future marked by human displacement due to floods. Researchers argue that the decisive driver of climate change is the greenhouse effect fueled by greenhouse gas emissions, and combined with high population and low resources, the risk of displaced populations is high. Global warming and population change will make it harder and harder to live there in the future, and one major indicator for this is the building and restoration of natural habitats. The different ground and water types make it challenging to keep and maintain the building and develop the land. Julia Rosen and Gabriel Siguan along with David Bresch both use research studies in their article. “In Julia's article “The average global temperatures have increased by 2.2 degrees Fahrenheit, or2.2 degrees Celsius, since 1880, with the greatest change happening in the later 20th century.” “Land areas have warmed more than the sea surface and the arctic has warmed the most by more than 4 degrees Fahrenheit since the 1960s.” In article 2 Gabriel) The author used eyewitness reports, data, and statistics, evidence from scientific experiments and studies. They also used data and methods by combining projection of flood hazard and population distribution, and then apply a vulnerability function to calculate displacement risk.                

The calculation is made using the open-source software CLIMADA (CLIMate ADAptation) which comes in six different global hydrological models. Julia in recent years we have seen severe weather and natural disasters. High winds, hail, excessive precipitation, and wildfires. When the atmosphere warms, the effects of violent storms are getting worse. Article2 The data and methods used to calculate the population exposure to river floods and displacement show that the globally averaged risk of people being displaced by river floods is projected to double (+110%) by the end of this century under a more optimistic scenario that is in line with the target of the Paris agreement (RCP2.6-SSP1), while this displacement risk is projected to increase by 350% under a scenario more in line with business as usual (RCP6.0-SSP4).

“The concentration of methane, the second most important greenhouse gas, has more than doubled.” “We’re now emitting carbon much faster than it was released 56 million years ago.” “These rapid increases in greenhouse gases have caused the climate to warm abruptly.” Article 2 “Future research could explore how displacement risk may be reduced by adaptation measures such as new protective infrastructure and land-use planning to encourage development in areas less exposed to flooding hazard.” “As well as factors that may increase or decrease the effectiveness of these and other ways to manage flood risks.” 

Julia “The years of research scientist uncovered that it’s an old organic matter by looking for carbon-14, which is radioactive and decays over time.” “They also figure out that the water vapor is the most abundant greenhouse gas in the atmosphere.” Article 2 Gabriela and David used six different global hydrological models (GHMs), (GCMs), (CM1P5), (CaMa) flood, GHG showed a significant increase in human displacement due to river floods and flood caused by global warming. Julia Rosen and Gabriel Siguan along with David Bresch all use an informative tone throughout they article. Julia” We also know that climate change is happening because we see the effects everywhere.  Ice sheets and glaciers are shrinking while sea levels are rising. Arctic sea ice is disappearing. In the spring, snow melts sooner, and plants flower earlier. Animals are moving to higher elevations and latitudes to find cooler conditions.” Gabriela “more frequent flood events in a warming climate contribute to the increase of river flood displacement risk, the growth of the population in flood-prone areas also increase this risk.” Julia’s:” The common source of confusion when it comes to climate change is the difference between weather and climate.” “Weather is the constant that we experience when we step outside.” Whereas climate is the long-term average of those conditions, usually calculated over a 30-year period.” Article 2.  “Future research could explore how displacement risk may be reduced by adaptation measures such as new protective infrastructure and land-use planning to encourage development in areas less exposed to flooding hazard.” “As well as factors that may increase or decrease the effectiveness of these and other ways to manage flood risks.” Julia’s The years of research scientists uncovered that it’s an old organic matter by looking for carbon-14, which is radioactive and decays over time.” “They also figure out that the water vapor is the most abundant greenhouse gas in the atmosphere.” Article 2. “To consider only the contribution of climate change to displacement risk, we also run simulations where only the flood hazard sets change with time, but the population distribution is kept constant at the year 2000 baseline. By mid-century, both RCP2.6 and RCP6.0 result in similar projections of displacement risk at around +50% (figure 1 (b). At the end of the century, RCP6.0 shows a further rise to around +150% increase of displacements risk, whereas the risk in RCP2.6 remains stable near +150%” Julia Rosen considers herself a scientist and hold a Ph.D. in the subject as to author’s Gabriela do not have a Ph.D. in the subject David does have a Ph.D. in the field Weather and Climate Risks. However, Gabriel and David do have some education and background to comment on the subject.  I look at several websites and found that Julia Rosen has more publications than Gabriela and David.  Her writing has appeared in Nature, Science, High Country News, National Geographic, and many other publications.

The Science of Climate Change Explained: Facts, Evidence and Proof and Global warming and population change both heighten future risk of human displacement due to river floods are similar as they both (are) both use research studies and getting worse due to greenhouse gas. Although Julia Rosen and Gabriel Siguan, along with David Bresch both, use research studies and an informative tone, Rosen has better credentials, and more publications as a result, Rosen's article is a more credible source than Gabriel and David’s. However, to prevent these river floods and climate change we need to burn less fossils fuels recycle more so that like product go into the landfill. We can use public transport, use renewable energy like solar power, wind power and hydroelectric power. Grow more plants also global warming has many other negative effects like overheating of plants more natural disasters more animals like polar bears will become extinct. The sea levels will rise increase probability of droughts leading to malnutrition, ice cap melting, more forest, and wildfires. Overall, I think we need avoid using fossil fuels and use other alternatives like renewable energy sources and we should try to develop and developing countries so that the population dose not increase drastically, and we can slow down the rate of Global warming if we all make a few changes to our lives.
