According to a joint report by the FAO and WMO, extreme heat could make agricultural work unsafe for up to 250 days a year by the end of the century in regions like South Asia, tropical sub-Saharan Africa, and parts of Central/South America. This risk threatens over 1 billion livelihoods and reduces labour capacity, as heat stress causes, crop yields to fall.

According to a joint report by the FAO and WMO, extreme heat could make agricultural work unsafe for up to 250 days a year by the end of the century in regions like South Asia, tropical sub-Saharan Africa, and parts of Central/South America. This risk threatens over 1 billion livelihoods and reduces labour capacity, as heat stress causes, crop yields to fall.
Key Impacts of Extreme Heat on Agriculture:
Unsafe Working Days: -
Over two-thirds of the year could become unsafe for outdoor labor, particularly affecting farming in tropical and subtropical regions.
Health Hazards: -
Farm workers are already 35 times more likely to die from heat exposure than other workers, with risks including heatstroke and chronic kidney disease.
Declining Yields: -
Crop yields are expected to fall by 7.5% per 1'C rise in temperature.
Livestock Mortality: -
Heat stress begins for common species at about 25∘C, reducing dairy yields and causing cardiovascular shock in pigs and chickens.
Compound Risks: -
Extreme heat is a "risk multiplier," intensifying the effects of drought and leading to lower yields and higher wildfire risks.
To address this, experts call for greenhouse gas reduction and strengthening climate resilience in food systems. 
Specific adaptation strategies (e.g., changing crop types, adjusting work hours).

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.
