Current Feed ContentCO2 levels rising faster than predicted - Greenpeace responseResponding to findings by the Global Carbon Project, published in the “Proceedings of the National Academy of Sciences” this week, that atmospheric CO2 levels have risen 35% faster than expected since 2000, Gavin Edwards, Head of Climate at Greenpeace International said: “Today’s extremely worrying findings add to the overwhelming scientific evidence of the intensity of the climate crisis. We have no more time to waste in tackling climate change. "The science is clear. The solutions are clear....Study says CO2 levels rising faster than anticipatedThe concentration of carbon dioxide (CO2) in the atmosphere is increasing faster than expected, according to a new study published in Tuesday's edition of the Proceedings of the National Academy of Sciences. The study said that rising levels of CO2, the main greenhouse gas blamed for climate change, threaten to accelerate global warming. The study attributes the change in CO2 levels to increased use of fossil fuels and a decline in the amount of gas being absorbed by the oceans and land. CO2...How Climatic Change Effects the Crop Growth and Development1. Effects of enhanced CO2 on crop growth Plants grow through the well-known process of photosynthesis, utilizing the energy of sunlight to convert water from the soil and carbon dioxide from the air into sugar, starches, and cellulose--the carbohydrates that are the foundations of the entire food chain. CO2 enters a plant through its leaves. Greater atmospheric concentrations tend to increase the difference in partial pressure between the air outside and inside the plant leaves, and as a... |
