Nitrogen is not a greenhouse gas because it does not absorb and trap heat in the atmosphere like other greenhouse gases such as CO2, CH4, and H2O.

Hydropower is the most widely used renewable energy source worldwide, accounting for about 54% of global renewable electricity generation.

Energy efficiency refers to the use of less energy to perform the same task or achieve the same level of output.

Agroforestry is a sustainable land use practice that integrates trees and shrubs with crops and/or livestock. It helps to improve soil fertility, reduce erosion, and increase biodiversity.

The primary goal of climate adaptation is to reduce the vulnerability of human and natural systems to the impacts of climate change, such as rising sea levels, extreme weather events, and changes in agricultural yields.

Increasing fossil fuel production is not a climate adaptation strategy because it contributes to greenhouse gas emissions, which exacerbate climate change.

Energy transition refers to the process of shifting from fossil fuels to renewable energy sources, such as solar, wind, and hydropower.

Energy efficiency reduces energy consumption, which in turn reduces greenhouse gas emissions.

Carbon Capture and Storage (CCS) involves capturing carbon dioxide from industrial sources or the atmosphere and storing it underground or in geological formations.

Investing in coal-fired power plants is not a climate mitigation strategy because coal is a fossil fuel that emits greenhouse gases when burned.

Climate-smart agriculture refers to agricultural practices that aim to increase productivity, adapt to climate change, and reduce greenhouse gas emissions.

Constructing dams is not a common climate adaptation measure in coastal areas because it does not address the specific challenges posed by sea-level rise and coastal erosion.

Reducing Emissions from Deforestation and Forest Degradation (REDD) is a climate mitigation strategy that aims to reduce greenhouse gas emissions from deforestation and forest degradation.

Increasing fertilizer use is not a common climate adaptation strategy in agriculture because it can contribute to greenhouse gas emissions and water pollution.

Sustainable transportation refers to transportation practices and systems that reduce greenhouse gas emissions and other negative environmental impacts.
