How Will Global Warming Affect The Future Generation

How Will Global Warming Affect The Future Generation – Greenhouse gas concentrations in the atmosphere will continue to rise unless annual emissions are drastically reduced by billions of tons. It should increase concentration.

Many greenhouse gases stay in the atmosphere for a long time. As a result, even if emissions stop rising, the amount of greenhouse gases in the atmosphere will increase and remain high for hundreds of years. Furthermore, if we stabilize rates and the composition of the current atmosphere remains stable (which would require significant reductions in current greenhouse gas emissions), surface temperatures will continue to warm. In fact, heat-storing oceans take many decades to respond to high levels of greenhouse gases. The oceans’ response to greenhouse gases and higher temperatures will continue to influence climate for decades or even hundreds of years.[2]

Warming Across Generations

Because it is difficult to remotely predict future emissions and other human factors affecting the climate, scientists have developed a series of scenarios using various assumptions about future economic, social, technological, and environmental conditions.

This figure shows projected greenhouse gas concentrations for four different emission pathways. The first scenario assumes that greenhouse gas emissions will continue to increase this century. The downward trajectory assumes emissions peak between 2010 and 2020 and decline thereafter.

We have seen global warming in recent decades. Future temperatures are expected to change even more. Climate models project the following important temperature-related changes.

Projected changes in global average temperature over four emission pathways (rows) for three different periods (columns). Temperature changes are relative to averages from 1986 to 2005. Trajectories come from the IPCC Fifth Assessment Report: RCP2.6 is very low emissions, RCP4.5 is medium emissions, RCP6.0 is a medium-high emissions trajectory. and RCP8.5 is a high emission trajectory (emissions are assumed to increase throughout the century).

Climate Change In The United States

The vertical bars on the right show the temperature variation at the end of the century, while the lines show the average of the climate models. Changes are relative to the 1986-2005 average.

Rain and storm conditions are expected to change, including rain and snow. However, some of these changes are less certain than temperature-related changes. Forecasts show that future changes in rainfall and tides may vary seasonally and geographically. Some areas may have less rainfall, some may have more, and some may have little or no change. Precipitation during the monsoon season is likely to increase in most regions, while hurricanes are expected to move poleward.[2] Climate models predict the following changes in precipitation and hurricanes.

Climate Change, Coastal Impacts, And Protecting Heritage And Future Generations

The maps show changes in precipitation at the end of this century compared to 1970-1999 under the high-emissions scenario. For example, during the winter and spring climate models agree that the northern regions of the United States will be wetter and the southern regions will be drier. There is little certainty as to where the transition from wet to dry areas will take place. Confidence in predicted changes is highest in areas marked with diagonal lines. Due to natural variability, the changes in white areas should not be more than expected. Source: United States National Climate Assessment, 2014. Click the image to enlarge.

Arctic sea ice is shrinking.[2] The extent of ice cover in the Northern Hemisphere has decreased since about 1970.[2] Permafrost temperatures in Alaska and much of the Arctic have increased over the past century.[1] Due to recent advances in ice and snow. To learn more about changes, visit the Ice and Snow page in the Indicators section.

Over the next century, sea ice is expected to continue to decline, glaciers to shrink, ice cover to shrink, and permafrost to melt. Possible changes in ice, snow and permafrost are discussed below. These maps show sea ice loss in the Arctic and Antarctic. Maps a) show average sea ice accumulation (relative area covered by sea ice) from 1986 to 2005. Maps b) and c) show climate models of sea ice thickness in late February and September. 21 Low (b) and high (c) emission conditions. In the Arctic, February should have less snow (more blue); September should be snow free (almost completely blue). The proposed changes to Antarctic sea ice are more subtle.

Uncovering Climate’s Secret Ally. Nature Has Slowed Global Warming…

Global sea levels have risen by about 7.5 inches since 1870. [2] Estimates of future sea levels vary by region, but global sea levels are expected to rise faster in the coming centuries than in the past 50 years.

Studies predict that global sea level will rise between 30 and 1.2 feet by 2100, with an uncertain range of 0.66 to 6.6 feet.[1]

The contributions of warming, ice sheets, and small glaciers to sea-level rise are relatively well studied, but the effects of climate change on the Greenland and Antarctic ice sheets are poorly understood and represent an active area of ​​investigation. Changes in ice sheets are expected to be responsible for 1.2 to 8 inches of sea level rise by the end of this century.[3]

Past and projected sea level rise from 1800 to 2100. The orange line on the right shows the current projected sea level rise of 1 to 4 feet by 2100. The wide range (from 0.66 feet to 6.6 feet) reflects uncertainty about how glaciers and ice sheets will respond to climate change. Source: NCA, 2014. Click image to enlarge. Regional and local factors will influence future relative sea level rise on coastlines around the world. For example, relative sea level rise depends on changes in land elevation, which are caused by subsidence (subsidence) or uplift (elevation). Assuming these historical geologic forces continue, a two-foot rise in global sea level by 2100 would result in the following relative sea-level rise:[4]

Argumentative Essay On Climate Change

Relative sea level rise depends on changes in local currents, winds, salinity, and water temperature, as well as the proximity of shrinking ice sheets.[2]

Ocean acidification negatively affects many marine species, including plankton, molluscs, clams, and corals. As the acidity of the ocean increases, the supply of calcium carbonate decreases. Calcium carbonate is an important component of the shells and skeletons of many marine organisms. If it is CO in the atmosphere

Although concentrations are currently increasing, the combination of global warming and ocean acidification could reduce coral growth by 50% by 2050.[5]

As carbon dioxide (CO2) emissions from the atmosphere enter the oceans, the oceans are becoming more acidic. This change is measured on the pH scale, with lower values ​​being more acidic. Ocean pH has decreased by 0.1 pH units since pre-industrial times, equivalent to a 30% increase in acidity. As the graph and map above shows, ocean pH is expected to decline further by the end of the century, as CO2 levels are expected to increase in the near term.[1][2]Source: IPCC, 2013, Chapter 6. .
