In this lecture you will be introduced to Earth system science a new holisitic approach to studying the Earth as a whole system of many interacting parts.
The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. We observe different stars in the sky at different times of the year.

The freeze-thaw threshold of 0°C is crucial in polar regions. Large changes in physical, biological, and human systems occur when temperature crosses this threshold. Therefore, any climate change that shifts the freeze-thaw line, whether in space or time, will bring about important impacts

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.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
"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.

How is energy distributed to the earth’s surface?
What are greenhouse gases and the greenhouse effect?
Impact of an increase in atmospheric CO2
on greenhouse effect
Recent changes in greenhouse gas concentrations
Relationship between the greenhouse effect and global
warming
5. The “Greenhouse Effect”
The Earth’s surface thus receives energy
from two sources: the sun & the
atmosphere
– As a result the Earth’s surface is ~33°C warmer
than it would be without an atmosphere
Greenhouse gases are transparent to
shortwave but absorb longwave radiation
– Thus the atmosphere stores energy

• Carbon Dioxide (CO2)
– Source: Fossil fuel burning, deforestation
Anthropogenic increase: 30%
Average atmospheric residence time: 500 years
Methane (CH4)
– Source: Rice cultivation, cattle & sheep ranching, decay
from landfills, mining
Anthropogenic increase: 145%
Average atmospheric residence time: 7-10 years
Nitrous oxide (N2O)
– Source: Industry and agriculture (fertilizers)
Anthropogenic increase: 15%
Average atmospheric residence time: 140-190 years
14. Summary
Greenhouse gases absorb infrared radiation and prevent it
from escaping to space.
Carbon dioxide, methane, and nitrous oxide are very good
at capturing energy at wavelengths that other compounds
miss
15. Greenhouse Effect & Global Warming
• The “greenhouse effect” & global
warming are not the same thing.
– Global warming refers to a rise in the
temperature of the surface of the earth
• An increase in the concentration of
greenhouse gases leads to an
increase in the the magnitude of the
greenhouse effect. (Called enhanced
greenhouse effect)
– This results in global warming
17. Climate Change vs. Variability
Even in a stable climate regime, there will always
be some variation (wet/dry years, warm/cold
years) A year with completely “average” or
“normal” climate conditions is rare
Climate variability is natural.
The challenge for scientists is to determine
whether any increase/decrease in precipitation,
temperature, frequency of storms, sea level, etc.
is due to climate variability or climate change.
19. Radiation is not evenly distributed over the
Surface of the earth. The northern latitudes have an
energy deficit and the low latitude/ equator has an excess.
But the low latitudes don’t indefinitely get hotter and the
northern latitudes don’t get colder.
Why?
The atmosphere and ocean transfer energy from low
latitudes to high
