One could say that we have a beef with the rising amount of methane (CH4) in the atmosphere: although this powerful greenhouse gas breaks down much faster than carbon dioxide, it traps 86 times more heat than CO2 over a 20-year span. Human activity has been the chief source of the increase in modern CH4 levels, having increased by about 150 percent since 1750, with about half of all human-generated methane coming from our livestock — particularly from the planet’s 1.5 billion cows. However, a new study has found that spicing a cow’s feed with simple seaweed can cut a burping bovine’s methane production by up to 99 percent.

 June 2017 was the third-hottest month of June on record, according to the National Oceanic and Atmospheric Administration (NOAA), putting 2017 on track to be the second hottest year on record. On the surface, this sounds like good news, but this means that 2017 will still be hotter than the years before 2014-2016’s record-breaking El Niño, an event that pushed 2016 into being the current temperature record holder.

A new study published in the journal Nature has illustrated that the global rise in sea levels is worse than originally anticipated, and the rate of increase is accelerating. Between 1993 and 2014, the rate of increase jumped by 50 percent, with the average rise in 1993 being 2.2 millimeters (0.87 inches), and 2014 showing a rise of 3.3 millimeters (0.13 inches). This study follows an earlier paper that found that sea level increases are now nearly triple that of their pre-1990 levels.
