Did you know that the oldest organism on Earth is believed to be a microorganism found in 3-million-year-old permafrost in Siberia? There, it was living at a cosy average temperature of -10 °C at 14 m depth. Or did you hear that some other Arctic soil microorganisms can happily live at extreme temperatures down to …[Read More]
The illustration above shows a sketch of the evolution of Arctic sea ice for different levels of warming and the different months of the year, based on the simple extrapolation of observations. A new study, in which I was involved, uses the latest available global climate models and shows that the Arctic Ocean could become …[Read More]
Understanding the climate evolution of our planet is not an easy task, but it is essential to understand the past if we are to predict the future! Historic climate cycles provide us with a glimpse into a period of time when the Earth was warmer than it was today. Our image of the week looks …[Read More]
Declining sea ice in the Arctic is definitely one of the most iconic consequences of climate change. In a study recently published in Science, Dirk Notz and Julienne Stroeve find a linear relationship between carbon dioxide (CO2) emissions and loss of Arctic sea-ice area in summer. Our image of this week is based on these …[Read More]
