Climate change refers to long-term shifts in weather patterns due to human activities like burning fossil fuels and deforestation that release greenhouse gases. This leads to an average rise in global temperatures, causing effects like sea level rise that threaten coastal regions and glacial melting that endangers wildlife. While some climate change occurs naturally from phenomena like volcanic eruptions, human activities are the main driver of currently observed changes like increased droughts and extreme weather events. Reducing greenhouse gas emissions through measures like improving fuel efficiency, expanding renewable energy, and increasing carbon sequestration can help mitigate further climate change impacts.
The Earth’s climate is dynamic and characterised by trends, aberrations and quasi-periodic oscillations varying over a broad range of time-scales [1], which are governed by external (extraterrestrial systems) and/or internal(ocean, atmosphere and land system). Trends are largely controlled by plate tectonics, and thus to change gradually on million year time scale. Aberrations occur when the certain thresholds are passed and are manifested in the geological record as the unusual rapid (less than a few thousands of years) or extreme change in climate. The quasi-periodic oscillations are mostly astronomically paced; they are driven by astronomical perturbations that affect the earth’s orbit around the sun and the orientation of earth’s rotation axis with respect to its orbital plane. These perturbations are described by the three main astronomical cycles: eccentricity, precession and obliquity, which together determine the spatial and seasonal pattern of insolation received by the earth [2], eventually resulting in climatic oscillations of ten to hundreds of thousands of year [3].Sun being the main source of energy for the earth system controls the climate of it. Variation in solar activity and cosmic ray intensity has direct influence over climatic features such as cloudiness, temperature and rainfall [4]. Volcanic eruptions also force all elements of the climatic systems up to a varying degree but producing long term climatic signals in the ocean. The cumulative volcanic cooling effect at present offsets about one third of anthropogenic warming [5].Other than these causes paleoclimatologists also relates the past climate changes with movement of solar system[6], interplanetary dusts and influence of asteroids[7].However the recent variability in climate what earth is experiencing is unlikely due to any of the individual above factors rather it is due to the compound effect of complex interactions of all the natural as well as anthropogenic forcings.

"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.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.
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.

3. What is Climate Change?
If the climate doesn’t remain constant, we call it climate change.
The key question is what is a significant change – and this depends upon the
underlying level of climate variability
Climate is the averageweather at a
given point and time of year, over
a long period (typically 30years).
We expect theweather to change a
lot from day to day, but we expect
the climate to remain relatively
constant.
4. First of all, we should know
that weather and climate is
not the same thing.
5. WEATHER is what’s
happening outside of
our window right now.
WEATHER IS:
• Short term
• Limited area
• Can change rapidly
• Difficult to predict
6. CLIMATE IS:
• Long term
• Wide area
• Seasonal changes
• Measured over long
spans of time
CLIMATE is the average of
many years of weather
observation.
7. Effects of Climate Change
An average increase in Earth’s temperature during the last
century
Migrating birds are forced to change their time and place of
migration
Melting of glaciers will lead to higher sea level, which will
cause floods and put many low-elevation regions at risk of
disappearing under water
Longer summers can disrupt animal habitation
New and widespread diseases because of warm climate
Damaged crops due to sudden climate change and floods
Average precipitation increase around the world
Melting of polar ice—polar bears and other animals are
drowning
Droughts, heat waves, extreme winters and storms, hurricanes,
typhoons
13. HUMAN CAUSES (Anthropogenic
or Man-made cause)
Greenhouse
gases
Deforestation
Coal mining
Burning of
fossil fuels
Industrial
processes
Agriculture
14. In a way, the earth is like a glasshouse. The earth has
some very important gasses in the atmosphere that
keeps us warm.
Some of these gases are water vapour, carbon dioxide,
nitrous oxide and methane.
When the sun heats the earth, these gases keep the heat
on the earth's surface. Without these gases, heat would
escape back into space and Earth’s average
temperature would be about 60°F colder.
15.
16.
17. Deforestation, clearance,
clear cutting or clearing
is the removal of a forest
or stand of trees from
land which is then
converted to a non-forest
use. Deforestation can
involve conversion of
forest land to farms,
ranches, or urban use.
18. The burning of fossil fuels by
humans is the largest source of
emissions of carbon dioxide,
which is one of the greenhouse
gases that allows radioactive
forcing and contributes to global
warming
22. Introduce automobiles with
new fuel system which
reduces 90% pollution
Engages with businesses to
reduce carbon emissions
Make others aware about the
problem
Build E-waste recycling
factory
Reduce vehicle use
Improve energy-efficiency in
buildings
Develop carbon capture and
storage processes
Triple nuclear power
Improve soil carbon
management strategies
23. Produce more fuel-efficient vehicles
Invest in renewable energies
Decrease deforestation/plant forests
Protect plants
24. Summary
Global surface temperatures have risen by
about 0.6°C since 1900
It is likely that this warming is larger than for
any century since 200AD, and that the 1990s
were the warmest decade in the last millennium.
The warming differs in different parts of the
world, but over the last 25 years, almost
everywhere has warmed, and very few places
have cooled.
Other changes have occurred, e.g.:
Sea level has risen by about 20 cm,
Ocean heat content has increased,
Almost all mountain glaciers have
retreated
Coincident with this global warming, levels of
CO2 (and other ‘greenhouse’ gases) have
dramatically increased, to levels higher than
those experienced for maybe millions of years.

the end..??

Now..Its Upto Us..What
We can Do..??
