The Global Warming Solution:- Evidence that humans are causing climate change is unequivocal, but the question of what to do about it remains divisive. Economic, sociological, and political issues all play a role in future planning.

Scientists use the phrase climate change to express the complex transformations already altering our planet’s weather and climate systems. A global discourse that began with concern over warming has now shifted to the larger term climate change. Climate change consequences include not only rising average temperatures, but also extreme weather events, shifting wildlife populations and habitats, rising sea levels, and a variety of other factors. As humans continue to emit heat-trapping greenhouse gases into the atmosphere, all of these effects are becoming apparent.

With the Paris Agreement in 2015, countries from all around the world recognized the need to act on climate change and pledged to reduce greenhouse gas pollution. The Intergovernmental Panel on Climate Change (IPCC), which synthesizes scientific consensus on the subject, has set a goal of keeping warming below 2 degrees Celsius (3.6 degrees Fahrenheit), with a goal of 1.5 degrees Celsius being pursued (2.7 Fahrenheit).

How is global warming caused?

Those two objectives are in peril. According to a UN report released at the end of 2018, major countries are already lagging behind on their pledges, and emissions levels in 2030 must be 25 to 55 percent lower than they were in 2017. According to previous research, even if countries complete their carbon reduction goals, those efforts will not be enough to prevent severe warming.

What options do we have for The Global Warming Solution?

There is no one-size-fits-all solution to addressing climate change. Nonetheless, nearly all of these solutions are already in place, and many of them rely on humans changing their behavior and shifting how they produce and consume energy. Changes in technology, behavior, and policies are all needed to encourage less waste and better resource management. Improved energy efficiency and vehicle fuel economy, as well as increased wind and solar power, biofuels from organic waste, carbon pricing, and forest protection, are all effective strategies to lower the quantity of carbon dioxide and other gases trapping heat on the globe.

Scientists are also researching on ways to manufacture hydrogen, which is now derived primarily from natural gas, in a sustainable manner in order to fuel zero-emission fuel cells for mobility and electricity. Other initiatives include developing better batteries to store renewable energy, designing a smarter electric system, and capturing carbon dioxide from power plants and other sources with the objective of storing it underground or converting it into valuable fuels like gasoline. Despite worries about safety, water use, and toxic waste, others say that nuclear power should be part of the answer because nuclear reactors do not emit any direct air pollution while in operation.

While it is vital to reduce new greenhouse gas emissions, scientists have also stressed the importance of removing existing carbon dioxide from the atmosphere. More fantastical proposals for cooling the world, such as spraying sunlight-reflecting particles into the air or blocking the sun with a big space mirror, have been mostly ignored since they may entail more environmental concerns than benefits.

Planting trees, restoring seagrasses, and increasing the use of agricultural cover crops, on the other hand, could help remove considerable amounts of CO2. Restoring trees that have been cut down in Brazil, for example, could remove 1.5 billion metric tons of CO2 from the atmosphere, according to recent research published by the National Academies of Science, and the world’s forests and farmland could store 2.5 gigatons of CO2. Given previous carbon emissions of 2.2 trillion metric tons, those are small numbers, yet every contribution is essential to change the world’s current course.

Adapt or face the consequences

Adaptation must be an element of the response to climate change, according to communities all around the world. A new wave of programs focuses on building resilience, from flood-prone coastal communities to regions suffering greater droughts and fires. Land erosion must be managed or prevented, microgrids and other energy systems must be built to survive disruptions, and structures must be designed with increasing sea levels in mind.

Recent works like Drawdown and Designing Climate Solutions have presented bold, comprehensive, yet easy solutions for reversing our current trajectory. Although the concepts differ, the message remains the same: we already have many of the instruments needed to combat climate change. Some of the proposals are big and require governments and corporations to execute them, but many others entail simple changes that anybody can do, such as eating less meat or rethinking your modes of transportation.
