CO2 fertilization |
|---|
|
The journal Nature Climate Change published a new study on the study of effects of carbon dioxide level on the greening on our land, according to the Environmental News Network. Defined as the ?amount of carbon dioxide in the atmosphere that has resulted from the rising anthropogenic emissions that help the growth of plants by using carbon dioxide during photosynthesis,? the carbon fertilization results from the anthropogenic emissions that we are fully responsible of. Carbon fertilization is known to increase the crop yields, seemingly beneficial to the farmers. Plants use energy through the process of photosynthesis. During this process, using sunlight, plants combine carbon dioxide from the air along with water and nutrients gained from the soil to produce glucose. The sugar produced during photosynthesis are mainly used for the fuel. Carbon dioxide fertilization makes this process way more complicated. Studies indicate that the increasing level of carbon dioxide encourage the plant growth, while increasing the greenhouse level in much faster rate. This overall increases the temperature and nitrogen concentration. However, because other factors – such as the nitrogen concentration, climate change by rising temperature,precipitation and the amount of sunlight changes- all impact the greening effect, Carbon dioxide fertilization has been studied using the data from the NASA- MODIS (Moderate Resolution Imaging Spectrometer) and NOAA(National Oceanic and Atmospheric Administration)-AVHRR (Advanced Very High Resolution Radiometer) satellites sensors in order to measure the accurate contribution of carbon dioxide to greening of the Earth. The data from the studies indicated that the carbon dioxide fertilization influences around 70 percent of the green effect, according to professor Ranga Myneni at the department of Earth and Environment at Boston University. Through this data, we were able to clearly see the heavy influence carbon dioxide has on the greening process. The trends show that the greening will continue, negatively impacting our weather and trigger droughts, floods, sea level rises, and ocean acidification.

@Arushi, first of all, I would like to apologize for checking out your comment so late!
I'm so grateful for your further research, your passion always amazes me <3
I'm glad you enjoyed the article, It fascinated me as well...
I'm actually very well aware of CO2 fertilization not only because of environmental interests I have but also from all the science classes! )
I definitely agree with you on how scientists are not clear of this situation.
Partially because researches all give different results that confuses scientists.
What I definitely believe though, is that CO2 will have definite impact on our climate pretty soon and that we-both scientists and environmental activists like us as well as, really, anyone around us - need to pay more attention to this problem and do more studies on it.

Yuna, thanks for informing us about CO2 fertilization. I hope Arushi has provided very detailed information according to your report. Learnt a lot from your article, and hope to meet your wonderful writing again soon! Have a great day!

Good concept. More research will clarify the situation better. Thanks for the post.

Thanks for posting on time, Yuna! and thanks Arushi for further research! I don't have much to talk about this new research, i'll definitely have some homework to do. i'll try to find more on the topic and read about it. thanks for giving us the latest discovery to think about!

Thanks for sharing such an interesting and new(for me) concept-CO2 fertilisation. I had never heard of it. After reading your report, I further researched on web to know more about it. Scientists are not very clear if it is real or an extremely risky assumption.
The potential CO2 benefit or so called CO2 fertilisation effect (CFE) only applies to some crops. It does not apply to maize and many other. Despite the potential positive effects on yield quantities, elevated CO2 may, however, be detrimental to yield quality of certain crops. For example, elevated CO2 is detrimental to wheat flour quality through reductions in protein content.
Also, even there is modest brief CO2 crop increase from the fertilization it is not expected to do anything for food/nutrition security under global climate change.
But it does seem to be a mixed blessing. Thanks again for adding to our knowledge.
