GLOBAL WARMING
‘Global warming‘ refers to the effect of human activities on the climate, primarily the fossil fuels (coal, oil, and gas) and huge deforestation, which together lead to large releases of ‘greenhouse gas emissions,’ most significant of which is carbon dioxide. As these gases absorb infrared radiation, the Earth’s surface remains warmer than it would otherwise be because they create a blanket over it. Global warming is totally a result of this Climate Change. The science behind the ‘greenhouse effect,’ which causes global warming, is well recognized. Numerical climate models that incorporate the essential dynamical and physical equations characterizing the entire climate system are used to gain more detailed knowledge.
Numerous of the likely characteristics of the consequent climate changes may be determined, for example, more frequent heatwaves, increased rainfall, and increased frequency and intensity of many extreme climate events. Significant uncertainties remain in our understanding of some of the climate system’s feedbacks (which affect the overall magnitude of change) and much of the complexity of expected regional change.
On Global Warming Serious Concern
Global warming is the most serious environmental concern the world faces because of its severe effects on human communities (including significant sea-level rise) and ecosystems. To mitigate the inevitable repercussions, both adaptation and mitigation are necessary. The scientific and political groups throughout the world are taking action on a global scale. The greatest difficulty, given the need for immediate action, is to transition quickly to considerably higher energy efficiency and non-fossil-fuel energy sources.
Since the 1880s, the average global temperature has risen by around 1.1 degrees Celsius. Satellite measurements and the analysis of hundreds of thousands of independent weather station observations from around the world have both corroborated this. The rapid loss of the planet’s surface ice cover adds to the evidence, according to scientists. This rate of global warming is at least an order of magnitude faster than any documented in paleoclimate records dating back 65 million years.
IMPACT
Climate change has an impact on human existence as well as the means of production that support our economy. We measure climate change by its impact on human life, physical capital, and the environment–
-
Livability and workability :are two terms that come to mind while discussing livability:
Heat stress could impair people’s ability to work outside or, in the worst-case scenario, put their lives in jeopardy. Temperature rises may potentially change disease vectors, affecting human health.
-
Food systems are important:
Droughts, harsh heat, and floods all have the potential to damage food production, yet a changing climate may improve food system performance in some areas.
-
Physical assets are what you have:
Extreme precipitation, tidal flooding, forest fires, and other risks could harm or destroy physical assets such as buildings.
-
Infrastructure services are provided:
Infrastructure assets can lead to a reduction in the services or an increase in the cost of those services, as they are a type of Physical asset and can have their functions interrupted.
- Natural capital is a term that refers to the value of Climate change is causing ecosystems to shift and natural capital to vanish, including glaciers, forests, and ocean ecosystems, all of which provide vital services to human populations. This negatively impacts both the human habitat and the economy.
Various risks, such as flooding, forest fires, hurricanes, and heat, can destroy assets or impede services provided by infrastructure assets. According to statistics, damage to capital stock from riverine floods might treble by 2030 and triple by 2050.
WHAT SHOULD POLICYMAKERS DO
Faced with these problems, policymakers, and corporate leaders will need to put in place the correct tools, analytics, procedures, and governance in order to properly assess climate risk, adjust to risk that has already been locked in, and decarbonize in order to prevent additional risk accumulation.
Societies have been adapting to changing climates, but the rate and scale of adaptation will almost certainly need to accelerate. Protecting people and assets, strengthening resilience, decreasing vulnerability, and ensuring that proper funding and insurance are in place are all important adaptation measures. For a variety of reasons, putting adaptation measures in place could be difficult. In some geographies, such as those subject to increasing sea levels, the economics of adaptation may deteriorate with time.
In some geographies, such as those subject to increasing sea levels, the economics of adaptation may deteriorate with time. Technical or other factors may limit adaptation. In other cases, there may be difficult trade-offs to consider, such as who and what to protect and who and what to relocate.
While adaptation is now critical and there are numerous adaptation options, climate science suggests that the only way to prevent future warming is to achieve net-zero greenhouse gas emissions. Although decarbonization is not the focus of this study, it will be necessary to include decarbonization expenditures alongside adaptation efforts, particularly in the transition to renewable energy. Stakeholders should evaluate their decarbonization potential as well as the benefits of decarbonization.
