  1. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO).

  2. The IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change:

    Increased Flooding: not detected, no attribution.

    Increased Meteorological Drought: not detected, no attribution.

    Increased Hydrological Drought: not detected, no attribution.

    Increased Tropical Cyclones: not detected, no attribution.

    Increased Winter Storms: not detected, no attribution.

    Increased Thunderstorms: not detected, no attribution.

    Increased Hail: not detected, no attribution.

    increased lightning: not detected, no attribution.

    Increased Extreme Winds: not detected, no attribution.

    There is no climate crisis.

    The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change:

    Pages 1761 – 1765, Table 11.A.2 Synthesis table summarising assessments

    Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution.

    Agricultural Drought: 31 out of 45 global regions low confidence in observed trend

    (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence).

    Ecological Drought as above.

    Hydrological Drought: 38 out of 45 global regions low confidence in observed trend.

    43 out 45 low confidence in human attribution (2 medium confidence, no high confidence).

    So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!

    There is no objective observational evidence that we are living in a global climate crisis.

    The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed:

    Air Pollution Weather (temperature inversions),
    Aridity,

    Avalanche (snow),

    Average precipitation,

    Average Wind Speed,

    Coastal Flood,

    Agricultural drought,

    Hydrological drought,

    Erosion of Coastlines,

    Fire Weather (hot and windy),

    Flooding From Heavy Rain (pluvial floods),

    Frost,

    Hail,

    Heavy Rain,

    Heavy Snowfall and Ice Storms,

    Landslides,

    Marine Heatwaves,

    Ocean Acidity,

    Radiation at the Earth’s Surface,

    River/Lake Floods,

    Sand and Dust Storms,

    Sea Level,

    Severe Wind Storms,

    Snow, Glacier, and Ice Sheets,

    Tropical Cyclones.

    How about some quotes from the UN's IPCC AR6?

    "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions."

    "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions."

    "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)."

    There is no objective observational evidence that we are living through a global climate crisis. None.

  3. People who sabotage to gain benefits are the threats to human beings, not the climate. Climate is the best thing ever for life. Greedy minds of oligarchs is the worst thing ever for the human race! Take your AI narrator and shut it.

  4. This video has the United Nations Climate Change disclaimer. Global warming was officially stated at 1.1°C in 1991 and 1.06°C in 2022. There is no mechanism that would allow greenhouse gas behavior to cause global warming.

    The back of the United Nation's IPCC science report states it took its greenhouse gas samples at 20,000 meters altitude where it is common high school level knowledge there is no greenhouse radiant energy. This is typical practice for deceptive marketing to state legal data transparency protecting the perpetrators from fraud prosecution. The IPCC has been transparent with its data acknowledging it is not dealing with active greenhouse gases.

    Earth's greenhouse effect is frequently used as a primary example to high school students of a system always in saturation from the strong greenhouse gas water vapor absorbing all the greenhouse radiant energy from the earth with greenhouse gases within 20 meters of the radiating surface that is all around us everyday and can't have its overall effect changed. There is no further greenhouse radiant energy to interact with greenhouse gases. At 1% average tropospheric water vapor over 99% of earth’s greenhouse effect is from water vapor. Water vapor would hold earth's greenhouse effect in saturation if it were the only greenhouse gas in the atmosphere.

    Arctic warming is taking place with the proving mechanism being warm Atlantic Ocean waters migrating deeper and more frequently into the Arctic Ocean warming it and the region. That warmer water is causing a few weeks less of reflective snow and ice coverage resulting in more solar heat gain to the Arctic region surface.

    Atmospheric CO2 levels of 1200 ppm about three times what they are today would greatly invigorate C3 plants the majority of plant life on earth greatly greening the planet.

    0.4% of the atmosphere is CO2 and on average 1% is H20 water vapor. (1% H20)/(0.4% CO2) = 25. Water vapor is 25 times more present in the atmosphere on average than CO2. Water vapor has an CO2e of 18, 18 X 25 = 450 CO2e total for water vapor to 1 CO2e for CO2.

    The Earth’s oceans have 3-1/2 million sea floor volcanic vents warming the water and changing it’s chemistry that have not been systematically accounted for.

  5. Subject:

     It will be possible to avert Climate Change, but considered proactive support of governments of developed and developing nations is mandatory. Let India play a lead role in this regard.

    Climate Change has become  a global survival issue now. Since it is a global issue, it needs to be addressed at global scale. 

                 Moreover, instead of wasting costly resources in wars and related wasteful activities, which are due to false ego, greed and undue fear of security among nations, it will be prudent to utilize these resources in mitigating global warming, which is causing climate change. Hence, let us all swear to shun wars, to stop production of machines of mass destruction and to support global peace.

              The unprecedented rains, floods, land slides, etc. are due to climate change. These calamities are causing untold sufferings to all the living beings globally and they will not spare any one in the near future. Therefore, governments of all the nations must have to act fast to avert climate change, before it is too late.

              The innovator of Carbon-sink plant reitrates that if these plants are installed globally at coal/fossil-fuel fired power plants and  industries, they will effecrively prevent discharge of colossal amount of  CO2, which is one of the major causes of global warming, while wars will further enhance the pace of global warming. Hence, in order to ensure survival living beings, wars must be stopped immediately.

               The Carbon-sink  plants can fix SOx and capture CO2 in very large amounts from flue-gases of the above said industries. An integrated Stripping plant will release the captured CO2. The released CO2 can be utilized to produce Ethanol, Methanol, Urea, salts, CO2 hydrates etc.

                Thus, Carbon-sink plants can effectivly mitigate global warming, but these plants cannot be installed without consudered involvement of governments of developed and developing nations, because these are very costly plants. Moreover, when there is an issue of survival, the cost and all other issues become insignificant.

               Therefore, the innovator of Carbon-sink plant is seeking an urgent response and support of the heads of governments of the above said nations, before it is too late.

              The innovator will be glad to share the concept of Carbon-sink plant with the experts of the above said nations. In this regard, please contact the innovator at this email ID:
