In the past two millennia, planetary mean temperatures have increased to the highest levels in millennia. This warming has been amplified in the Arctic and subsurface sea ice. Global mean temperatures are expected to rise by as much as ten degrees Celsius. This warming is consistent with the CO2 greenhouse effect, and the adverse impacts of such dramatic climate changes are incalculable. But the true cause of global warming is Human activity, which is primarily responsible for the increase in greenhouse gases, such as carbon dioxide.
Humans are the primary cause of global warming
It has been long thought that natural factors alone can explain the warming trend we’ve seen in recent decades, but new research indicates that humans are the primary cause. Using fossil fuels to heat up homes and power our cars has increased https://www.carbonclick.com/personal-footprint-calculator/ concentrations in the atmosphere. During the Industrial Revolution, humans began burning these fuels in large quantities. This has caused a dramatic rise in the concentration of carbon dioxide in the atmosphere. CO2 is the most significant contributor to global warming and has increased the greenhouse effect. Since 1950, humans have contributed to global warming more than any other human activity.
Carbon dioxide
Although scientists have long debated the contribution of carbon dioxide to global warming, there is no doubt that it is a contributing factor. Moreover, carbon dioxide is a natural component of the atmosphere. It constantly exchanges between the land, ocean, and microorganisms. Absent human impacts, the amount of CO2 in the atmosphere tends to balance out. But carbon dioxide emissions and removal are a result of human activities.
Methane
One major source of methane emissions in the atmosphere is landfills. More people should be recycling to reduce landfills. Landfills also pollute the atmosphere and soil. By reducing the amount of methane released into the atmosphere, we can limit global warming. However, methane buildup may continue and can increase greenhouse gas concentrations. So what can be done about it? We can take steps to reduce methane emissions by using greener energy and reducing waste.
Deforestation
Deforestation is the systematic destruction of forests, a process that robs climate change fighters of a key weapon and creates further emissions. Most carbon is stored in plants and soil, but also in rocks and minerals beneath the planet’s surface. As the population increases, big business has been able to profitably clear forests and plant mega-crops like soy and oil palm.
Subsistence farmers, meanwhile, are removing trees to grow crops to feed their families.
Natural forcings
The study of the Earth’s average temperature has revealed that it was more or less stable before industrialization. Since the earth’s average temperature is known, researchers can calculate radiative forcing based on a reference year. The Intergovernmental Panel on Climate Change has selected 1750 as the baseline year. The model’s results suggest that global warming could increase by 0.3 K each year. The question remains, what are the causes of global warming?
Climate change
While the US and Europe are making progress in cutting back on carbon emissions, developing countries are lagging behind. China has overtaken the US as the world’s biggest emitter of greenhouse gases. In 2007, China surpassed the US as the world’s largest emitter. The United States has emitted 50.7 billion tons of carbon since 1950, but India and China have four times more population. Furthermore, over 60 percent of all industrial carbon dioxide is produced in these countries.
Climate emergency declarations
The Canadian House of Commons passed a non-binding climate emergency resolution this week that characterized climate change as an emergency. But the Trudeau government approved a controversial pipeline expansion, underscoring the inherent problem of climate emergency declarations. The Trudeau government has repeatedly declared an emergency in response to climate change, but its policies contradict that declaration. This article examines how climate emergency declarations are flawed and discusses the potential downsides of the policy.
