Dear Researchers: I am wondering why we say the Climate is Changed. I think it doesn't make sense, because in science, the word "Change" is used to describe a situation when a phenomenon changes from One State to Another State without returning to its Initial State, correct?
But, Climate components, e.g., temperature and precipitation, have been going through Temporal Variability over the scale of days, weeks, months, years, decades, centuries, and ..., due to Temporal Variability in Solar Activities, correct (please, exclude the yearly seasonal variability due to the rotation of Earth's axis)?
If we think about the two periods in our Geological History such as the Ice Age and the Warming Era, it can prove that climate had been historically varying over Temporal Scales, correct? And, those Variabilities had nothing to do with human and human activities when at the Ice Age and the Warming Era, no human existed on the Earth, correct?
So, who was in charge of those variabilities if humans were not existing on Earth?
Sun and Temporal Variability in Solar Activities?
And, the last but most important question, when air temperature varies/fluctuates over two consecutive days, do you think the amount of greenhouse gases, especially the criminal one, CO2, can be that much increased/decreased Over A Day to cause the variations in air temperature?
Or, the Variations in Air Temperature for the most part is because of the Variations in Solar Activities with subsequent Variations in Solar Heat Release?
And the 2nd last question, can the horrifying words "Climate Change" with further implications made out of it to blame Humans as the main driver of "Climate Change" significantly influence our minds and hearts to Easily Accept the Depopulation of our Planet Earth by ...?
And the 3rd last question, can a substantial decrease in the CO2 level of our Earth's Atmosphere have some sort of side effects (negative impacts) on our Earth's Environment in coming years? And, do we know what would be the optimum amount of CO2 level in our Earth's Atmosphere? And, can we take enough well-representative samples from the Atmosphere to figure out a very good estimate of CO2 level as the Atmosphere is vastly distributed in multidimensions with no clear boundaries and with very dynamic behaviors over spatial and temporal scales?
Updates on April 20, 2024: First, many thanks to all contributors to this discussion for sharing their thoughts and ideas. I want to expand the scope of this discussion after reading all the answers provided by the contributors to this discussion, as follows:
Please, also consider that asking these questions doesn't mean I am against environmental pollutants; instead, I advocate for having clean environments and thus saving lives, for example, by manufacturing electric cars or generating electricity following the green (more environmentally friendly) approach using wind turbines or solar panels.
However, we may not be able to avoid the consumption of fossil fuels in our lives as most of the appliances used in houses, cars, factories, industries, etc, are plastic-based and made from fossil fuels.
So, if it is impossible to avoid the consumption of fossil fuels in our lives and given that the produced CO2 from burning fossil fuels is a food source for plant growth and flourishing on the Earth, what other things, beyond the green approach of generating electricity, could be done to protect the environment and reduce the pollutants?
We know that environmental damage & pollution are highly related to poverty. Could the consumption of fossil fuels, by filtering out the pollutants (not the CO2, as it is not a pollutant to air since plants are consuming it during daily photosynthesis and producing it during nocturnal respiration) in the refineries and factories, boost the economy of producer and consumer countries of fossil fuels and thus reduce poverty around the world?
If so, may the world leaders and rulers care more about patriotism & nationalism than wrongly defined globalism and thus help to elect a person in each country to improve their economy and eventually reduce poverty?
May following this approach help to minimize environmental destruction and pollution and further consequences such as water and migration crises around the world?
Dear Khodabakhsh Zabihi Afratakhti,
There is a broad consensus among climate scientists affirming the reality of climate change, and human actions predominantly drive it, specifically the release of greenhouse gases such as carbon dioxide (CO2) and methane (CH4). While natural factors can impact Earth's climate, the evidence strongly supports the conclusion that contemporary climate change is primarily a result of human activities. Although natural elements like fluctuations in solar activity can influence the climate, their effect is comparatively minor when contrasted with the impact of human activities. Rigorous monitoring of solar activity has failed to reveal any significant upward trends that could account for the recent global warming.
Best regards,
Thanks, Brook Legese Dadi for your contributions to this discussion! But, why the rigorous monitoring of solar activities has failed in this modern era of science and technology?
If failed, how could we say the effect of solar activities on climate is less than the effect of human activities on climate?
Dear Khodabakhsh Zabihi Afratakhti;
Monitoring solar activities has not failed; rigorous monitoring has thrived in the modern era. Nowadays, with the aid of advancements in science and technology, our understanding of solar activity has significantly deepened, surpassing previous levels. We now profoundly grasp the sun's behavior, encompassing sunspots, solar flares, solar irradiance, and solar cycles.
While solar activity indeed plays a role in shaping Earth's climate, its current impact is deemed less significant compared to the influence of human activities, particularly the release of greenhouse gases. This conclusion is the product of extensive scientific research, thorough data analysis, sophisticated modeling, and an overwhelming body of evidence substantiating it.
If there were indeed a failure in monitoring, how would they have been able to conduct a comprehensive analysis and arrive at a conclusion?
Thanks, Brook! Do you think whatever is published in science could be 100 % correct, and there won't be any uncertainty associated with it due to any driving factor in our contemporary science?
And, why the contemporary climate should behave differently than the historical climate? I mean the driving factors of climate variability.
Dear Khodabakhsh Zabihi Afratakhti,
You are right, especially regarding publications related to climate change. Given the intricate nature of this issue, it is difficult to claim that all the research comprehensively covers every contributing factor, even though achieving such comprehensiveness is impossible.
The present-day climate can diverge from historical patterns due to a combination of natural variability and the considerably heightened impact of human-induced changes. As you know in the past, human activities had a relatively minor influence on the climate. However, with the global population's growth and the expansion of industrialization, our planet is now grappling with the challenge of maintaining its ecological balance, as it has exceeded its carrying capacity.
Thanks, Brook for your contributions to this discussion. I agree with you that human activities may to some extent influence climate, but we need transparency in science.
I mean the impacts of both variability in solar activities, causing variability in solar heat release, and human activities on the climate variability need to be Cleared Out and Teased Apart to see who is the most influential driver.
I am sharing a short article about solar activities with you and all who read this discussion from the NASA website that I read a few months ago and now it says the page is not available. But, I found other sources who added that article on their websites as follows:
https://www.nasa.gov/centers/goddard/news/topstory/2008/solar_variability.html
https://phys.org/news/2008-05-solar-variability-climate.html
https://www.sciencedaily.com/releases/2008/05/080512120523.htm
Unless the main driver of climate variability is not cleared out, may the current worldwide efforts of decreasing CO2 levels in the atmosphere drive our Earth's environment into a different environment than it was supposed to be a normal one?
Khodabakhsh Zabihi Afratakhti ,
we do not say the climate has changed. We say that the climate is changing and if nothing is done to stop the changes the new state will be catastrophic for mankind.
The evidence for the changes is here https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt
however it has been found that presenting evidence to climate sceptics like yourself only makes them more convinced that they are correct.
Thanks, Alastair Bain McDonald for your contributions to this discussion and for providing those records of data!
However, I am confused with this data. Could you please explain to us why temperatures in the hottest months of the summer season, such as July and August, were negative in 1880-1980?
Do we have a record of climate data before 1880 to compare century-to-century patterns of climate data? If not, how could we prove our claims based on this dataset with very strange negative records of temperatures during summer seasons?
My concern is that who is the most responsible factor for the climate variability? Human activities or Solar activities? I also added a couple of concerns at the end of my question today.
Hello, first and foremost, climate change is the result of a combination of man-made and natural factors.
Second, to answer this question, a complex system of behaviors and system performance should be considered.
Third, we have evidence that human activities and population dynamics will exacerbate climate change in some areas. Over-harvesting of surface and underground water, threats to biodiversity, extensive changes in land use, excessive emission of greenhouse gases and various types of air pollutants, are all examples of climate change at the spatial and micro levels differences. They are very important.
Thanks, Habib Sadeghi for your contributions to this discussion! A question may be raised here is how much of that variability is related to Human Activities versus Solar Activities.
