Life affects the composition of the atmosphere and therefore the climate because different life forms take in and release gases like carbon dioxide, methane and oxygen at different rates. As the climate changes, species and ecosystems respond by adapting, migrating or reducing their population.

The atmosphere protects us from UV and other short wavelength light that would otherwise do a lot of damage to the DNA of living organisms. The atmosphere is also important because it contains oxygen, which we and other living organisms breathe.

The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.

Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.

Climate change and poverty are deeply intertwined because climate change disproportionally affects poor people in low-income communities and developing countries around the world. Those in poverty have a higher chance of experiencing the ill-effects of climate change due to the increased exposure and vulnerability.

Climate change isn’t simply a political or economic issue. It’s a human rights issue, perhaps the biggest one in human history. If we continue spewing greenhouse gases into the atmosphere, we not only destroy ecosystems and drive species to extinction, we indirectly violate human rights.

States have a human rights obligation to prevent the foreseeable adverse effects of climate change and ensure that those affected by it, particularly those in vulnerable situations, have access to effective remedies and means of adaptation to enjoy lives of human dignity.

Increases in pests and diseases and more frequent and intense droughts and floods, reduce the availability of food. Heat-stress causes poor yields, or worse, crop failures. Reducing short-lived climate pollutants gives us our best chance to rapidly limit global temperature rise and reduce the risks to food security.

If we want to prevent at least some of these changes, action must be taken in all areas of life over the next two decades. The responsibility for tackling climate change lies with decision-makers, industry, and ordinary citizens.

The legislative, executive, and judicial branches all have a role to play in reducing U.S. greenhouse gas emissions and building resilient communities. Congress is responsible for authorizing laws to address the climate challenge and appropriating funding for relevant programs.

The Carbon Majors Database report names the following 10 companies as those which belch most carbon dioxide into the atmosphere:

• China Coal 14.3 %
• Saudi Aramco 4.5 %
• Gazprom OAO 3.9 %
• National Iranian Oil Co 2.3 %
• ExxonMobil Corp 2.0 %
• Coal India 1.9 %
• Petróleos Mexicanos 1.9 %
• Russia Coal 1.9 %

the developed world is responsible for most of climate change situation today. Over 70% of the greenhouse gases emission was due to the developed countries, while India’s contribution is just 3%. There was overconsumption by the people in the developed world.

100 companies are responsible for 71% of global emissions, study says. Just 100 companies have been the source of more than 70% of the world’s greenhouse gas emissions since 1988, according to a new report…

The federal government has the industry’s back Catering public lands to fossil fuel extraction is highly irresponsible. They already contribute greatly to the climate change problem: Over 20 percent of total U.S. climate emissions come from oil, gas and coal extracted on those lands.

Global emitters (1965 to 2017)

According to the study, a 330ml can of Coca-Cola sold in Great Britain has a carbon footprint of 170 grams and the same sized can of ‘diet Coke’ or ‘Coke Zero’ has a footprint of 150 grams. A 330ml glass bottle of ‘Coca-Cola’ has a footprint of 360 grams.
