Hydrogen is a gas that can be emitted from industrial activities. Increasing production levels of hydrogen indirectly contributes to rising global temperatures. It is important to understand how much hydrogen was in the atmosphere in the past, so we can quantify how much it contributes to rising temperatures. Antarctic ice cores contain a record of trapped hydrogen gas, so measuring the amount of hydrogen gas in the ice core can help us understand how much hydrogen was in the atmosphere in the past. Here, we present a method that has produced the first measurements of hydrogen gas in Antarctic ice. Preliminary results show that the amount of hydrogen trapped in the ice is lower than the amount of hydrogen in the air today. Ongoing work aims to make a precise connection between the amount of hydrogen measured in the ice and how much hydrogen was actually in the air in the past.
