If human industry increases atmopheric Co2 from 200ppm to 450ppm, what change in degrees C to the earths energy budjet is attributed to the 250ppm increase in Co2

The increase in atmospheric CO₂ from 200 ppm to 450 ppm has significant implications for the Earth’s energy budget and climate. Let’s explore this:
Pre-Industrial CO₂ Levels:
Before the industrial revolution, atmospheric CO₂ levels were around 278 ppm¹.
This value serves as the pre-industrial baseline for CO₂.
Current CO₂ Levels:
As of March 2021, atmospheric CO₂ levels have reached approximately 417 ppm¹.
This represents a 50% increase over the pre-industrial average.
Impact on Global Warming:
The rise in CO₂ contributes to global warming by enhancing the greenhouse effect.
Scientists estimate that if CO₂ doubles (reaching around 550 ppm), it could raise the average global temperature by 2 to 5 degrees Celsius².
However, we are currently halfway toward this “doubled-CO₂” scenario.
Equilibrium Climate Sensitivity (ECS):
ECS is a benchmark used to quantify long-term future global warming.
The current CO₂ rise corresponds to approximately 50% of doubled-CO₂.
If CO₂ levels continue to increase, we may surpass this threshold.
Future Projections:
At the current rate, CO₂ levels are expected to exceed 500 ppm within 50 years ³.
Such levels could lead to temperature increases of more than 3 degrees Celsius (5.4°F), impacting weather patterns, sea levels, and ecosystems.
In summary, the 250 ppm increase in CO₂ significantly affects the Earth’s energy balance, contributing to ongoing global warming. It underscores the urgency of addressing climate change through mitigation efforts and sustainable practices

It’s a logarithmic function. Each time [CO2] is doubled, according to the logarithm, there should be 4 W /m/m in forcing.
