CLIMATIC EFFECTS OF NUCLEAR WAR, INCLUDING NUCLEAR WINTER : REPORT OF THE SECRETARY-GENERAL
Birks concluded Etrat snoke from extensive forest, oil and gas fires tollowing a nuclear war nould drastically reduce the amount of sunlight reaching Ehe Earthrs surface. As a conseguence, it was estimated t.hat agricultural produclion in the nort,hern hemisphere would be almost totally eliminated. (...) Both effect,s were caused by the absorption of sunlight by the smoke aerosol. As a resultr a massive t.emperature inversion formed so that narmerair overlay cold air near the surface. (...) We have very little confidence in Ehe near-term ability to predict this phenomenon quantit.atively, either in terms of the amount of sunlight obscured and the related temperature changes, the period of t,ime such conseguences may Persist' or of the levels of nuclear attacks which might initiate such consequences. ...'

Not only do they have a negative impact on human health but they can also induce atmospheric cooling by reflecting sunlight back to space, or by absorbing sunlight in the atmosphere so that it never reaches the ground. (...) The measurements indicate that atmospheric aerosol amounts continue to decrease (see Figure 5), consistent with the decrease in the light extinction by particles (that is, the collective impact of aerosol particles reducing the amount of sunlight that reaches the ground, whether by absorbing or reflecting sunlight) that began in the 1980s for Central Europe and North America and in the 2000s for Northern Asia, South America and most of Africa (IPCC, 2021). This decrease indicates the effectiveness of air quality policies in reducing atmospheric aerosol particles and their precursors; however, such reductions also increase the amount of sunlight (and thus heat) reaching the Earth’s surface.

All of this within tiny cells with no access to natural sunlight or running water. As a signatory of the Convention Against Torture and Other Cruel, Inhumane and Degrading Treatment and of the Convention on the Rights of the Child, the Government of Australia should, by all means necessary, comply with the stipulations herein and immediately halt the inappropriate treatment of children at Don Dale.

Are vitamin D supplements needed if individuals are not exposed to sunlight due to lockdowns? Vitamin D can be made in the skin by exposure to sunlight or obtained through the diet from natural sources (e.g. fatty fishes such as salmon, tuna and mackerel, fish liver oils, beef liver, cheese and egg yolks), or from vitamin D-fortified foods or vitamin D-containing supplements.   In situations where individuals’ vitamin D status is already marginal or where foods rich in vitamin D (including vitamin D-fortified foods) are not consumed, and exposure to sunlight is limited, a vitamin D supplement in doses of the recommended nutrient intakes (200-600 IU, depending on age) or according to national guidelines may be considered.

(...) Ground-level ozone — formed when pollutant emissions (e.g. nitrogen oxides) from cars and other sources react with other pollutants in sunlight — affects plant growth and is estimated to cause relative global crop losses for staple foods like soy (6%-16%), wheat (7%-12%) and maize (3%-5%) . (...) Mosses as monitors of pollution Since 1990, naturally growing mosses have been sampled every five years in the framework of ICP Vegetation.

They have the ability to produce food using the energy from sunlight. As other living beings cannot produce food, they depend on plants for nutrition. (...) Soil is the Foundation of Nutrition on Earth Plants are known as the “primary producers” on Earth as they can produce food using energy of sunlight. Plants are the starting points of food chains and food webs. (...) Reasons for Soil Salinization Both natural processes and human activities are causing soil salinization.
