The Stop Global Warming calculator shows you how much carbon dioxide you can prevent from being released into the atmosphere and how much money you can save by making some small changes in your daily life. It’s our hope that the calcula
Ultimately, what really matters isn’t the amount of greenhouse gas emissions; what matters is the higher temperatures and their impact on humans. And on that front, a gas like methane is much worse than carbon dioxide. It drives the temperature up immediately, and by quite a bit. When ...

If you decide to include real-time regional carbon intensity numbers in your calculation, then imagine this scenario; You release a code change and your carbon metric goes up. Did your code change make the application worse or has the electricity become dirtier? In ...
The carbon captured from the atmosphere during this process is also used as the structural foundation for creating organic compounds essential for growth and development. Photosynthesis uses other mechanisms – light and dark reactions with photosystems I and II to absorb light. To understand these me...
As climate change stokes larger and more intense wildfires, firestorms are likely to become more common. Here’s why they occur and what makes them so dangerous.
The ultimate goal of the carbon credit system is to reduce the emission of GHGs into the atmosphere. Key Takeaways Carbon credits were devised as a mechanism to reduce greenhouse gas emissions. Companies receive a set number of credits that decline over time. They can sell any excess credits ...
