What are two factors that contribute to the earth having an energy budget less than zero?

The Earth's energy budget can be less than zero due to factors such as increased greenhouse gas emissions, which trap heat in the atmosphere and lead to an imbalance in energy absorption and radiation. Additionally, deforestation and land-use changes can reduce the planet's albedo, affecting how much solar energy is reflected back into space. These factors disrupt the natural energy balance, contributing to a net energy deficit.
