co2 why what where

Graham Westbrook Professor of Geophysics at the University of Birmingham, warns: if this process becomes widespread along Arctic continental margins, tens of megatonnes of methane per year – equivalent to 5-10% of the total amount released globally by natural sources, could be released into the ocean.

The team is carrying out further investigations of the plumes; in particular they are keen to observe the behaviour of these gas seeps over time.

I currently believe that climate change is real but not the effect of human activity. Why do politicians (particularly liberals) love climate change so much?
Please do not try to convince me that climate change is real or fake. That is NOT my question. Thanks!

the observed warming

Scientists at the National Oceanography Centre Southampton working in collaboration with researchers from the University of Birmingham, Royal Holloway London and IFM-Geomar in Germany have found that more than 250 plumes of bubbles of methane gas are rising from the seabed of the West Spitsbergen continental margin in the Arctic, in a depth range of 150 to 400 metres.

Methane released from gas hydrate in submarine sediments has been identified in the past as an agent of climate change. The likelihood of methane being released in this way has been widely predicted.

Assuming all the light, water and food was provided and only the CO2 level was raised how high would the CO2 level have to get to harm the plants?
The minor drops in temperature right after 1900 and after 1960 coincide with reduced solar activity. To be sure, while this simple calculation may be enough to explain the observations, it is not a mathematical proof that the warming that has occurred since the days of James Watt is entirely due to human activity. It merely represents the simplest possible explanation.

Weather forecasting is an initial conditions problem. Climate forecasting is a boundary condition problem.
Initial condition that define the current state of the atmosphere are updated with every iteration of a forecast model. Beyond the first set, the initial conditions for each successive iteration are based on the output of the model and could be in error. These errors accumulate with each future iteration and the weather forecast skill deteriorates with time.
Measured initial conditions are therefore useless to climate prediction models, which are weather forecast models adapted for assessing climate change.
Rather than initial conditions, boundary conditions are described:
“Climate forecasts are produced in a different fashion, as here the problem is fundamentally a boundary value one. The circulation of atmosphere and ocean in such a climate model is not dependent on the initial state of the model but rather on the boundary conditions like the input of solar energy and the chemical composition of the Earth’s atmosphere (e.g. greenhouse gases). You cannot predict the weather for individual days with a climate forecast (for example, the question of the temperature in Hamburg on the 23.12.2005 is meaningless), but you can say something about the average conditions for an area (e.g. the average January temperature between 2010 and 2020), as well as the probability and magnitudes of deviations from this average.”
In other words, the little unknowable details are less valuable in a predictive sense than are large scale parameters confined to within a range of likely variability when assessing climate change.

And how many loaves of bread are made each day worldwide?
Hence how many tons of CO2 are generated each day from bread rising?
Can switching to unleavened bread significantly contribute to reducing the production of CO2?
Actual figures of CO2, and number of loaves worldwide per day, are what I’m really after.
