Opportunities to tackle short-lived climate pollutants and other ...

1. Introduction. To limit the global temperature increase to below 1.5 °Celsius (C), it is critical to not only reduce carbon dioxide (CO 2), but also a particular group of non-CO 2 greenhouse gases (GHGs) and precursors, and short-lived climate pollutants (SLCPs), including emissions of black carbon, methane (CH 4), tropospheric ozone, and fluorinated gases such as hydrofluorocarbons (HFCs).

"Gold Recovery for Dummies?"

Take filter with clean gold mud and gently squeeze of any excess water and place filer with mud into crucible for melting. 16. Once melted, the gold will again take on the appearance of metal. If you've followed the instructions carefully and used filters, the gold will be 999.5 % Pure with virtually no losses.
