    1) Global temperatures have risen 0.85°C between 1880-2012 and the rate of warming has doubled since 1979. 2) Global temperature is likely to rise above 1.5°C between 2030-2050, exceeding the targets set in the Paris Agreement. 3) Limiting warming to 1.5°C compared to 2°C would significantly reduce impacts to ecosystems, health, and weather, but meeting this target requires unprecedented changes across energy, land, and other systems through investments in low-carbon technologies and efficiency.

    Global Temperature

    Rise

    Background
    ■Global phenomenon of gradual increase in
    average temperature of earth surface and
    oceans due to anthropogenic activity and
    natural activity.
    ■Climate remained stable over the one or
    two thousand year before 1850(pre
    industrial period) except regionally varying
    fluctuations.
    ■Currently, the average global temperature
    is approximately 1°C above pre industrial
    level.
    Trends of temperature rise

    �1880 and 2012, the


    global average (land
    and ocean) surface
    temperature
    increased by 0.85
    [0.65 to
    1.06] °C. Since 1979
    the rate of warming
    has approximately
    doubled
    (0.13±0.03 °C per
    decade,
    against 0.07±0.02 °C 
    per decade) Temp diffrence
    Alaraming
    ■Global temperature is likely to rise above
    1.5 °C between 2030 and 2050.
    ■All country committed under the paris
    agreement to limit the global temperature
    rise to 1.5˚C and not to exceed 2˚C. 
    ■We are not in track to meet climate change
    target and rein in temperature increase.
    What is 1.5% goal ?
    ■ Limiting global temperature rise to 1.5 °C
    compared with 2°C to reduce challenging
    impacts on ecosystem, human health and
    well-being" .
    ■ And that a 2 °C temperature increase
    would exacerbate extreme weather, rising
    sea levels and diminishing Arctic sea ice,
    coral bleaching, and loss of ecosystems,
    among other impact.
    What diffrence half degree
    could make ?
    1.5˚C 2˚C 2˚C Impacts
    Extreme heat 14% 37% 2.6X
    Sea ice free arctic At least 1 every At least 1 every 10x worse
    100 year 10 year

    Sea level rise 0.40 meter per 0.46 meter per 0.6 m more
    year year

    Species loss 8% 16% 2x worse


    -plant
    Species loss – 4% 8% 2xworse
    vertebrates
    Ecosystem shift 7% 13% 1.86% worse
    Coral reefs 70-90% 99% up to29 % rise
    decline
    permaforset 4.8million km 6.6 million sqaure 38% worse
    Net zero emission
    �In addition to large emissions cuts in the
    next decade emissions will be on average
    need to reduce to zero by mid century
    �Air pollution leading to climate change
    must be addressed
    �Critical role of short lived but highly potent
    pollutants such as methane and
    hydrofluorocarbons
    �Co2 dominates long term warming,
    reduction of other pollutants can
    contributes to the 1.5 goal
    Reducing the emisions
    �Annual emissions need to be about half  by
    2030 to limit warming to 1.5˚C
    �behavior and technologies will need to shift
    across the board in order to achieve these
    emissions reductions. 
    �Energy efficency and fuel switching for
    transportation ,reducing energy demand
    ,improving efficency of food production
    reducing food loss and waste have
    significant potential to reduce emmisions
    Unprecedeted
    �There is no precedent in our documented
    history for the rate of change at the scale
    required for limiting warming to 1.5˚C
    �Shifting will need to be made across land
    energy industries urban and other systems
    �monumental shift will require substantial new
    investments in low-carbon technologies and
    efficiency
    �investments in low-carbon energy technology
    and energy efficiency will need increase by
    roughly a factor of five by 2050 compared to
    2015 levels.
    Thank you
