Or, if their view at least agrees that we humans are supposed to be good stewards of the world, then the matter can be settled quite simply: Each generation of humans should leave the world to the next generation with the
same carbon dioxide concentration in the atmosphere that existed when it «inherited» the world.
«A significant challenge for the future is increasing
carbon dioxide concentrations in the atmosphere,» said senior author Tobias Erb, a research group leader at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany.
«We argue that it was the establishment of the modern deep ocean circulation — the ocean conveyor — about 2.7 million years ago, and not a major change in
carbon dioxide concentration in the atmosphere that triggered an expansion of the ice sheets in the northern hemisphere,» says Stella Woodard, lead author and a post-doctoral researcher in the Department of Marine and Coastal Sciences.
The last time researchers believe
the carbon dioxide concentration in the atmosphere reached 400 ppm — between 3 and 5 million years ago during the Pliocene — Earth was about 3.5 to 9 degrees Fahrenheit warmer (2 to 5 degrees Celsius) than it is today.
The carbon dioxide concentration in our atmosphere has increased by 25 percent in just the past 70 years, allowing the plant to amass enough carbon dioxide without fully opening its stomata.
However,
the carbon dioxide concentration in the atmosphere — roughly 290 ppm (parts per million)-- was ca. 110 ppm lower than the current level, as ice core data from the Antarctic shows.
The dataset includes e.g. information on the future development of winds and temperatures in the Antarctic, and is based on the assumption that
the carbon dioxide concentration in the atmosphere will reach 700 parts per million by the year 2100.
The cause of those anomalies varied by region, the researchers discovered when they looked more closely at OCO - 2 and other satellite data showing changes in biological productivity,
carbon dioxide concentration in the atmosphere and other measurements.
Researchers at the Department of Medical Biochemistry and Biophysics at Umeå University have been working during the last years to develop methods that allow for refinement of climate models, to assess the role of plants to reduce
the carbon dioxide concentration in the atmosphere, and also to elucidate how plant metabolism is affected by climate change.
«This will cause carbon loss from the soil which means an increase in
carbon dioxide concentration in the atmosphere, which will further worsen global warming,» said Takeshi Ise from the Japan Agency for Marine - Earth Science and Technology.
Hence, increase of
carbon dioxide concentration in the atmosphere is not the cause of global warming which has a solar origin and is a part of natural two - century cycle»
Let's start with a brief overview of the most important data and facts about the increase in
the carbon dioxide concentration in the atmosphere:
The carbon dioxide concentration in the atmosphere is self - regulating, depending on its physical properties together with natural laws like the thermodynamics.
Is there any evidence that
carbon dioxide concentrations in the atmosphere, prior to the industrial revolution, ever approached the concentrations that we are seeing now?
Furthermore, the authors hail this as a harbinger of good things to come, explaining «the net effect of continued warming and rising
carbon dioxide concentrations in the atmosphere is most likely to be beneficial to humans, plants and wildlife.»
The authors of the new report say «the net effect of continued warming and rising
carbon dioxide concentrations in the atmosphere is most likely to be beneficial to humans, plants, and wildlife.»
«rising
carbon dioxide concentrations in the atmosphere will spur plant growth, increasing agricultural yields and literally making deserts bloom.»
