Humidity refers to the amount of water vapor in the air. There are three main types of humidity: absolute, relative, and specific. Absolute humidity is a direct measure of the mass of water in a given volume of air. Relative humidity compares the actual water content of the air to the maximum amount the air can hold at a given temperature. Specific humidity measures the ratio of water vapor to total air mass. Relative humidity is affected by temperature and the amount of water in the air. High humidity can impact climate, plants, animals, human comfort, and more. The most humid areas tend to be near the equator and coastal regions.

Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. It is expressed as grams of moisture per cubic meter of air (g/m3).
The maximum absolute humidity of warm air at 30°C/86°F is approximately 30g of water vapor - 30g/m3. The maximum absolute humidity of cold air at 0°C/32°F is approximately 5g of water vapor - 5g/m3.
Relative humidity also measures water vapor but RELATIVE to the temperature of the air. It is expressed as the amount of water vapor in the air as a percentage of the total amount that could be held at its current temperature.

Water is hydrosphere is made up of all the water on Earth. This includes all of the rivers, lakes, streams, oceans, groundwater, polar ice caps, glaciers and moisture in the air (like rain and snow). The hydrosphere is found on the surface of Earth, but also extends down several miles below, as well as several miles up into the atmosphere. So, there is a need for study of water as a scarce resource.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
2. Humidity
A measure of the
amount of water in
the air
Water is added to
the air by the process
of EVAPORATION.
3. Humidity
Humidity indicates the
likelihood of
precipitation, dew, or
fog.
Humidity is as well
as relative humidity
measured in %
The amount of
water that is
actually in the air
measured in g/mᵌ
5. ABSOLUTE HUMIDITY: Absolute humidity (expressed as grams of water
vapor per cubic meter volume of air) is the mass of water in the air.
Types Of Humidity
6. • RELATIVE HUMIDITY is the amount of water in the
air compared to the amount of water the air could
possibly hold.
• Humidity values are usually given as Relative Humidity.
Examples:
if the air is holding half the water it could hold, it’s Relative
Humidity is 50%.
If the air is holding no water, relative humidity is 0%
If it holding a quarter of the water it could hold, 25%
Types Of Humidity
7. Factors that Affect Relative Humidity
•Amount of water: If you increase the
amount of water in the air (by adding it due
to evaporation), Relative humidity will go up.
•Temperature: Since warm air can hold more
water than cold air, if you lower the
temperature the Relative Humidity will go up,
even if you don’t add more water.
Types Of Humidity
8. • Specific humidity is the ratio of the mass of water vapor to the total
mass of the moist air parcel.
• Water (mass) mixing ratio is the mass of water vapor compared to
mass of dry air
Types Of Humidity
11. If the air is holding ALL the water it can hold it is saturated
and the relative humidity is 100%
Saturation
12. • DEW POINT is the temperature at which
condensation will occur. The Dew point is the
temperature the air must be in order to be
saturated.
Dew Point
15. • WARM AIR CAN HOLD MORE WATER VAPOR THAN COLD AIR, so
with the same amount of absolute/specific humidity,
• cooler air will have a HIGHER relative humidity, and warmer air a
LOWER relative humidity.
6/12 *100=50% 6/24*100=25%
Facts
18. • Relative Humidity is measured using a PSYCHROMETER.
– A psychrometer is made of two thermometers. One is
covered with a wet cloth. When air moves over the wet cloth,
evaporation occurs and lowers the temperature on that
thermometer. If you compare the temperature on the two
thermometers you can get the relative humidity.
Measuring Humidity
19. • In the area of the vegetation, relative humidity is high whereas in the
bare land there is less moisture and relative humidity is also less.Vegetation
• The relative humidity increases as the altitude increases. Because as we
go higher, there is the decrease in the temperatureAltitude
• At the higher elevation than 800m relative humidity is less compared to
sea level.Orographic effect
• The average maximum diurnal relative humidity occurs in early morning
and the minimum diurnal humidity occurs in the early afternoon.Transfer of humidity
Factors which affect the humidity
20. Humidity affects global climate in in two major ways.
• First, water vapor in the atmosphere contains "latent" energy. During
transpiration or evaporation, this latent heat is removed from surface liquid,
cooling the earth's surface. This is the biggest non-radiative cooling effect at
the surface. It compensates for roughly 70% of the average net radiative
warming at the surface.
• Second, water vapor is the most abundant of all greenhouse gases. It absorbs
the infrared energy emitted (radiated) upward by the earth's surface.This
selective absorption causes the greenhouse effect.
Global Climate
23. Spatial distribution
• The most humid cities on earth are generally located closer to the equator, near
coastal regions.
• Cities in South and Southeast Asia are among the most humid. Kuala Lumpur,
Jakarta, and Singapore have very high humidity all year round because of their
proximity to water bodies and the equator and often overcast weather. Some
places experience extreme humidity during their rainy seasons such as Kolkata,
Chennai and Cochin in India, and Lahore in Pakistan.
• Sukkur city located on the Indus River in Pakistan has some of the highest and
most uncomfortable dew point in the country frequently exceeding 30 °C (86 °F)
in the Monsoon season.
• Shanghai and Hong Kong in China also have an extreme humid period in their
summer months.
• In cooler places such as Northern Tasmania, Australia, high humidity is
experienced all year due to the ocean between mainland Australia and Tasmania.
