Are There Climate Consequences of Using Hydrogen as a Replacement for Coal, Gas and Oil?

By: Keith Shine There are many possible avenues to reduce carbon dioxide emissions. One of these is a shift to using hydrogen (H2) as a fuel source; it could potentially be used for many current CO2-emitting activities, including industry, heating … Continue reading

Why should we care about sea ice floes?

By: Adam Bateson One of the most frequently used visual devices to illustrate climate change is that of a polar bear on sea ice surrounded by open ocean (Fig. 1). Polar bears are today identified as a vulnerable species, with sea ice decline the … Continue reading
