In the Middle Ages, the Catholic Church introduced people, exchanging donations for their paper slips, which promised to give them less time in purification after their deaths. Less controversially, today anyone who overestimates the supply of tea may be forced to pay a replacement fee. Are carbon se fuses more similar to the former or the latter?
There are many reasons why you might try to fass off part of your carbon footprint, whether it evokes a general sense of guilt for your lifestyle, definitely covers the estimated emissions of the flight, or just does something beneficial to the environment. Regardless of the motivation, all these efforts are predicted on the assumption that the money you actually paid will result in the removal of the promised amount of CO.2 From the atmosphere. Otherwise, you’re paying for a lie – or at least you’ll get less tea than you ordered.
It’s really hard to tell if you’ve been lied to. Here’s what you need to know.
Reducing the carbon cycle
Carbon dioxide in the atmosphere is part of a bio-geo-chemical dance called the carbon cycle. Carbon regularly cycles in form and field codes, atmosphere, ocean, ecosystems and bedrock. Plants take carbon atoms from CO2 To grow in the air. Vegetarians consume plants and emit carbon as CO2 Again. Weather Rocks CO. Draws2 Volcanoes out into the air release it into the atmosphere. These are just some of the exchanges of the carbon cycle.
Before the Industrial Revolution, these currents were in equilibrium, maintaining a constant concentration of CO.2 In the atmosphere. But then we found fossil fuels for fun and profit and ways to light them on fire. It took in more and more carbon that had spent millions of years closing it underground and releasing it into the atmosphere. Some of that carbon (actually, a little over half) was taken up by oceans and land ecosystems. But the rest accumulated in the atmosphere, pushing the concentration of greenhouse gases more and more.

Billions of tons of C.O. In, this is the best estimate of the current carbon cycle flow2 Per year.,

This is how much CO2 We have been emitting since 1850, minus the amount taken by oceans and land ecosystems.
To stop the growth of this greenhouse gas, our CO. Total total emissions of2 It is easy to reach zero. We can participate there by eliminating emissions from some of our activities. But we have to compensate for the current emissions to reach pure zero.
Some carbon sequestration projects help achieve this goal by preventing emissions that would have happened otherwise. Others promise that in terms of the carbon cycle it is referred to as someone “sinking” – forests such as a sustainable form of carbon or mineralized carbonate into the soil. These se fassets are not always the same for inhibited emissions, as they may have a different climate effect from carbon. For example, forests may be darker than their surroundings, so their expansion affects local sunlight as more sunlight is absorbed. But deforestation also has the potential to provide other ecosystem services such as animal habitat. So there are many factors beyond carbon to consider.
Make like a tree and leaves
Planting trees is an easy answer to climate change. (For evidence, see: Knee shock internet comments.) But our ability to store carbon in this way is limited. We can undo the emissions caused by past deforestation, but we never plant enough to consume enormous amounts of fossil fuels. But, even if you accept that limitation, a lot can go wrong after your seedlings get mixed up in the dirt.
Assuming you have found a program that you can really trust to plant the promised trees, a lot of things will affect the impact of their carbon cycle over time. The first way is that the tree species grows. Some are growing rapidly, accumulating a lot of carbon in acres over the past decade or so, providing immediate support to our carbon emissions balance sheet. But fast-growing trees are generally less ga ense than slow-growing species, so the final amount of carbon stored per acre is lower.
Fast-growing species also tend to have shorter lives. If the trees in this plantation are managed for pruning, life will end sooner. So where does the carbon go? Some can be converted into wood, at which time its value as a carbon sink depends on how long the lumber lasts, the remaining plant material decays or burns, releasing carbon back into the atmosphere, which His time ends as an end. Drowning,
Even if planted trees are not pruned, their carbon can be released in other ways. Of course, old trees die and rot. The bug infestation rips through forests, and cuts down trees. Wildfires can do the same. Some of these risks are increasing due to climate change, meaning that in many areas forest carbon storage is becoming less and less secure over time.
