Carbon dioxide levels fluctuated between 180-300 parts per million in the last 800,000. This level is unprecedented and will continue to rise. But the increase is not the only difference. Climate can be affected by many factors.
Recent research shows that carbon dioxide levels in the early days of life were less than 10 times as high as they are today. They may have been 50 million years old. They were much warmer than today's levels of CO2 and not too far from the current levels.
It is clear that carbon dioxide is a greenhouse gas. But it is important that we also consider temperature. Researchers have been able examine Earth's atmosphere for more than a century. Our atmosphere's composition has been known for 800,000. The relationship between temperature and CO2 is still not fully understood. This team of researchers has developed a new chemical method that can be used in order to estimate CO2 levels in a distant past.
The technique involves determining the ratio of boron to calcium in the shells of ancient single-celled marine algae. Tripati's group has calculated the atmospheric carbon dioxide levels in the past by using averaging the rates for boron/calcium over a period of 1000 years. The carbon dioxide level was at 280 parts of million at the time.
Tripati's team will continue pushing the record back for the next 20,000,000 years. They are confident that they will be able make accurate estimates for carbon dioxide levels throughout the entire period. If this method proves successful, we might finally understand how CO2 contributes to global warming.
The data can be incorporated with Earth system model models to get a complete picture of the carbon dioxide exchange with the atmosphere. Data assimilation is a combination of model simulations and actual measurements in order to give the most accurate view of the CO2 exchange through the atmosphere.
OCO-2 satellite launched in 2014 to measure atmospheric CO2 at regional scales. Ground-based sensors have previously been used to track measurements. These methods have been widely used to track rising CO2 concentrations for decades.
As the Earth warms, CO2 levels should increase. The average atmospheric carbon ppm will reach 600 parts per Million by the 21stcentury. The oceans will also warm by 0.2C every decade during the same time period. Global warming is greatly influenced by the ocean, which absorbs more heat than land.
However, the US Energy Information Administration has stated that fossil fuel consumption is down by almost 47% over 20 years. Although this is a very small number, it is an indication of the future.
While global temperatures have not increased in the past decade but they have been increasing rapidly, the atmospheric carbon has been growing at an alarming pace. Unless action is taken to slow CO2 emissions, we will see a further rise in our carbon dioxide levels.

What are the environmental and social effects of climate changes?
Climate change has many impacts on society and the environment. Climate change can have many effects on the environment. These changes can have serious implications for human populations, creating instability in communities, intensifying poverty and insect-borne diseases, altering human migration patterns, and destroying vital habitats.
Already, climate changes are having wide-ranging and profound effects on the environment worldwide. As global temperatures rise, this trend is likely to intensify in the near term.
One of the most widespread effects of climate change is the rising ocean levels due to melting of ice caps. This leads to shoreline erosion at many coasts as well as an increased risk for flooding for coastal communities. Saltwater intrusion is also a problem, and can negatively impact freshwater supplies along the coasts of many countries.
Due to climate change, extreme weather phenomena such as heatwaves/droughts frequently occur across many countries in the world. These events result in mass destruction of homes or businesses and can lead to relocation or complete loss of life. Extreme storms can also cause flooding and landslides, which increase the damage to infrastructure like roads and railways.
Also, wildfires due to climate change are occurring more often than ever. These fires can cause severe damage to habitats and the lives of people living close by.
These dramatic changes in living conditions can often lead to displacement and even refugee crisis when people leave their homes voluntarily or involuntarily due to their changing climate.
An increase in aridity means that dust storms can occur more frequently, making people with asthma and other respiratory illnesses like asthma particularly vulnerable. Furthermore, pest infestations are predicted to rise in tandem with warmer temperatures. This phenomenon is known as the 'greenhousebug'. Global food insecurity will continue to grow as fewer crops have lower nutritional qualities. This could potentially lead to more hardships for people already struggling to make ends work.
