Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. According to the National Oceanic and Atmospheric Administration (NOAA), the amount of CO2 in the air in May 2020 hits an average of slightly greater than 417 parts per million (ppm), the highest monthly average value ever recorded. What we need now is a new era of development - a development that is forceful and at the same time socially and environmentally sustainable. If we fail to follow it, we will follow the failure of humanity through a systematic extinction instead of development and well-being.

1. CARBON EMISSION OR GLOBAL DEVELOPMENT:
WHICH SHOULD BE CONSIDERED FIRST?

2. Introduction
• “The world is entering a new geologic epoch, sometimes called the
Anthropocene, in which human activities will largely control the evolution of
Earth's environment. Carbon emissions during this century will essentially
determine the magnitude of eventual impacts and whether the Anthropocene
is a short- term, relatively minor change from the current climate or an
extreme deviation that lasts thousands of years.” (National Research
Council, 2011).
• Globally, 2020 was the hottest year on record, effectively tying 2016, the
previous record. According to the National Oceanic and Atmospheric
Administration (NOAA), the amount of CO2 in the air in May 2020 hits an
average of slightly greater than 417 parts per million (ppm), the highest
monthly average value ever recorded.
• The rising temperatures of both the atmosphere and oceans are altering
worldwide weather patterns while there is a strong link between Carbon
dioxide (CO2) emissions, prosperity and standards of living as the
correlation between real GDP, energy consumption, and carbon emissions
are very tight.

3. SLOW YET
SIGNIFICANT
DEBACLE
• “The past few decades have
been warmer than any other
comparable period for at least
the last 400 years, and possibly
for the last 1,000 years or
longer” (National Research
Council, 2010).
• Continuing the planet’s long-
term warming trend, 2020’s
globally averaged temperature
was 1.84 degrees Fahrenheit
(1.02 degrees Celsius) warmer
than the baseline 1951-1980
mean

4. CONTEMPORARY
CLIMATE CHANGE
IS FUELED
PRIMARILY BY
HUMAN
INFLUENCE
• While greenhouse gases exist
in the atmosphere naturally,
human activity, particularly
since the start of the industrial
age in roughly 1850, has
increased the concentrations of
carbon dioxide (CO2), which
has increased principally due
to greater fossil fuel use since
the industrial revolution and
from deforestation.
• Emissions have continued to
proliferate; we now emit over
36 billion tonnes each year.

5. What is Coming Next?
• The Arctic was previously considered a carbon sink, a very
recent study terrifyingly finds melting permafrost could unleash
way more carbon than we thought. It is estimated that the
world’s permafrost contains up to 1,700 billion tonnes of
carbon, which is almost double the amount of carbon in the
Earth's atmosphere and four times more than what has already
been emitted by humans since the Industrial Revolution.
Patzner et al. (2020) has shown that the melting Arctic may
unleash far more carbon than even our worst-case models have
predicted.

6. Who Contributes to
CO2 Emission?
• Until well into the 20th century,
global emissions were
dominated by Europe and the
United States. In 1900, more
than 90% of emissions were
produced in Europe or the US;
even by 1950, they accounted
for more than 85% of emissions
each year. Emissions have
continued to proliferate; we
now emit over 36 billion tonnes
each year.

7. Who Contributes to
CO2 Emission?
• On a production basis, the
richest (high and upper-middle-
income) countries accounted
for half of the population but 86
per cent of emissions. On a
consumption basis, the result
is the same, but resulting from
the fact that upper-middle-
income countries primarily
export emissions to high-
income countries.

8. Ethical Concerns about Low Carbon
Policy Implementation?
• At low levels of human development, increased greenhouse gas
emissions can be considered a human right as they are linked to the
fulfilment of basic human needs (e.g. energy access, development of
basic infrastructure etc.)
• In contrast, increased emissions in rich countries are often
associated with luxurious consumption
• Hence, Equity and justice concerns have been central to the
international negotiations of the UNFCCC from the outset.

9. What if We Do Not
Restrict CO2
Emission?
• With concentrations already
exceeding 417 ppm and
emissions at record levels,
warming is likely to exceed 2ºC
in the long term unless a sharp
and sustained decline of at
least 80 per cent in emissions
by 2050 compared to 1990 is
underway before 2020.
• Under “business as usual”
emissions scenarios, the 2ºC
warming is likely to be reached
globally by 2060 or earlier, and
temperatures will continue
rising well beyond that time
(Joshi et al., 2011; Rogelj et al.,
2011).

10. Ways Forward
• We are using 50 per cent more resources than the Earth can provide, and unless we change the
course, that number will grow very fast - by 2030, even two planets will not be enough.
• However, we do have a choice …….
• We can produce the food we need without expanding our agriculture footprint –through reducing
waste, which now claims much of the food we grow, using better seeds and better cultivation
techniques, bringing degraded lands back into production, and changing diets – particularly by
lowering meat consumption in high-income countries.
• We need to establish water management regimes that involve a broader range of stakeholders and
that manage river basins as the complex, richly diverse living systems that they are.
• We can meet all of our energy needs from sources like wind and sunlight that are clean and abundant
and further cut our total energy use in half using that from renewable sources

11. Ways Forward
• We all need to play a role in keeping this a living planet – with food, water and energy for all, and the
vibrant ecosystems that sustain life on Earth
• We all have to follow the followings:

12. Conclusion
• Emerging economies are posing risk not meeting their aspirations for improved living standards,
and high-income countries and communities risk seeing their current well-being eroded
• All together the humanity risks facing a complete extinction
