Abstract. Many metrics for comparing greenhouse gas emissions can be expressed as an instantaneous Global Warming Potential multiplied by the ratio of airborne fractions calculated in various ways. The Forcing Equivalent Index (FEI) provides a specification for equal radiative forcing at all times at the expense of generally precluding point by point equivalence over time. The FEI can be expressed in terms of asymptotic airborne fractions for exponentially growing emissions. This provides a reference against which other metrics can be compared.

Abstract Landfill is a place where waste reaches the final stage. The piles of waste can generate greenhouse gas emissions that cause global warming the potential of climate change. The greenhouse gas emission generates from the piles of waste is CH4 emission. The research purpose is to count CH4 emission in the waste landfill in Medan city located in Terjun, projection CH4 emission for ten years later is 2020-2029 and decisive the effort reduction of CH4 emission. The scenarios of reducing CH4 emission in Terjun waste landfill reduce the potential CH4 emission for ten years later. The calculation of CH4 emission from the piles of waste in Terjun waste landfill using FOD method (First Orde Decay) by IPCC (Intergovernmental Panel on Climate Change) in 2006. In 2019, CH4 emission in Terjun waste landfill was 12,350.750-ton CH4 and had an uplift in 2029 can reach 17,143.087-ton CH4. There are two scenarios for reducing CH4 emission in the Terjun waste landfill; the first is the processing of waste in the source (composting), and the second is reducing the waste by using incineration technology Terjun landfill. The first scenario (composting) can reduce CH4 emission by 14.80%. The second scenario can reduce by 63.37% the CH4 emission in Terjun waste landfill. The chosen alternative scenario for reducing CH4 in the Terjun waste landfill is the first scenario, the processing of waste in the source (composting).

Automotive Emission

This report explains how California has historically enacted regulation curtailing conventional pollutants and greenhouse gas emissions. By examining previous California automotive emission controls that have led to the development of similar standards across the country, it can be argued that California has the capacity to be a leader in climate change policy and greenhouse gas emission standards in the future. This means that the air pollution problems of the state are not a burden, but rather an incentive to develop a policy countering global warming at the federal level. In this analysis, a rationale is established for interest groups to aim at California state regulations if they wish to improve automotive emission policy in the United States, and potentially reduce the effects of global warming worldwide [...]

Abstract The wave of national net zero CO2 and greenhouse gas emission targets could, if fully implemented, reduce best estimates of projected global average temperature increase to 2.1–2.4°C by 2100 and could bring achievement of the Paris Agreement within reach. 127 countries are discussing, have announced or have adopted net zero targets, which together cover 63% of global emissions. Together, these net zero targets could significantly lower projected global warming compared to currently implemented policies (2.9 to 3.2°C) or to the pledges submitted to the Paris Agreement (2.6 to 2.9°C).

Surge Height

In order to evaluate the future storm surge risk at the national scale, it is necessary to evaluate typhoon characteristics for a country-specific in prior to conducting storm surge simulation using them. When projecting future changes of tropical cyclones (TC) by using the atmospheric general circulation model (AGCM), there are several uncertainties due to model resolution, model physics parameterization, given sea surface temperature (SST) under future climate condition, and global warming scenarios. The uncertainties stemming from physics and numerical modeling configuration can be reduced by improving the accuracy of AGCMs, while those from the global warming scenario and future SST condition are unable to be. This study assessed uncertainties in projecting future change to typhoon properties such as tracks, frequency and intensity and extreme storm surge height (SSH) depending of future SST and greenhouse gas emission scenarios.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/Wzp35k4tyhM
