SLCP – A Danger To MankindA report on the dangers that SLCPspose to mankind and some usefulsolutions to tackle it’s growth andspread.
WHAT ARE SLCPs ? Short-lived climate pollutants (SLCPs) are agents that have relatively shortlifetime in the atmosphere - a few days to a fewdecades - and a warming influence on climate. The main short lived climate pollutants are: Black carbon Methane Tropospheric ozone Hydroflourocarbons
BLACKCARBON Black carbon create thick winterhaze that hugs the southernfoothills of the Himalayas & thishaze warms the atmosphere andmay contribute to rising regionaltemperatures, melting glaciers. While CO2 is the primary culprit,recent studies suggest that blackcarbon (BC) may play as large arole in warming the HKHT region

METHANE Emissions from fossil fuel production —specifically methane released from oil and gaswells and coal mines — accounts for nearly half asmuch again near-term warming as combustionitself. As global fossil fuel production and useexpands, vented and leaked methane willexacerbate the CO2 Fortunately, technology fixes to reduce methaneemissions abound.
TROPOSPHERIC OZONE Tropospheric ozone (O3) is the ozone present inthe lowest portion of the atmosphere (up to 10-15km above the ground). It is responsible for a large part of the humanenhancement of the global greenhouse effect. It is formed by sunlight-driven oxidation of otheragents in particular methane (CH4)
HYDROFLOUROCARBONS HFCs are man-made greenhouse gases used in airconditioning, refrigeration, solvents, foamblowing agents, and aerosols Though they represent a small fraction of thecurrent total greenhouse gases, their warmingimpact is particularly strong and, if leftunchecked, HFCs could account for nearly 20 % ofclimate pollution by 2050.
Why Dealing With SLCPs isImportant ? SLCPs represent as much as a 33% increases in averageglobal temperature. Due to their short lifetimes, actions to reduce emissionsof short-lived climate pollutants will quickly lower theiratmospheric concentrations. Action on SCLPs can help buy time in addressing the moreimportant and longer-term greenhouse gas (GHG)emissions.
