Energy Imbalance and Feedback Mechanisms

The main reason for Earth's energy imbalance is the excess of incoming solar radiation over outgoing long-wave radiation.

Cooling Feedback Mechanisms

The feedback mechanism that generally causes cooling in the Earth's atmosphere is the ice-albedo feedback.

Water Content and Outgoing IR Radiation

High water content in the atmosphere reduces outgoing IR radiation, leading to an increase in the greenhouse effect.

Feedback Mechanisms and Temperature

The feedback mechanism associated with an increase in the greenhouse effect due to a rise in temperature is the water vapor feedback.

Cloud Feedback and Climate

Cloud feedback is likely to have a positive effect on climate, amplifying the warming trend.

Global Mean Energy Budget Imbalance

The main reason for the current global mean energy budget imbalance is the increasing levels of greenhouse gases, such as CO2, in the atmosphere.

Factors Contributing to Habitability

One factor that is NOT contributing to the habitability of Earth is the absence of a strong magnetic field.

Convection in the Atmosphere

The main function of convection in the atmosphere is to distribute heat from the equator to the poles.

Roles of Water and CO2

Water and CO2 play a crucial role in the atmosphere, with water being a potent greenhouse gas and CO2 being a key contributor to the greenhouse effect.

Surface Temperature Response

The expected response of Ts (surface temperature) to the existing energy imbalance is to continue to rise.

Negative Feedback Mechanisms

The ice-albedo feedback is currently operating as a negative feedback mechanism, cooling the planet.

Clouds and Climate

Clouds affect climate by influencing the Earth's energy balance, with low-level clouds generally cooling the planet and high-level clouds warming it.
