Selected intervals in the past that were as warm or warmer than today can help us understand what the Earth may be like under future global warming.

A latest assessment of past warm periods, published today in Nature Geoscience by an international team of 59 scientists from 17 nations, shows that in response to the warming ecosystems and climate zones will spatially shift and on millennial time scales ice sheets will substantially shrink.

Coal power versus wind and solar energy – debates about the Paris climate targets often centre around electricity supply. Yet, even in a world of stringent climate policies and a clean power generation, the remaining use of fossil fuels in industry, transport and heating in buildings could still cause enough CO2 emissions to endanger the climate targets agreed on by the international community, an international team of researchers finds. Published in Nature Climate Change, their elaborate study is the first to focus specifically on the residual fossil fuel emissions from sectors that are not as easily decarbonized as power generation.

A quarter of the seafood tested from Metro Vancouver grocery stores, restaurants and sushi bars is not what you think it is.

Limiting global warming to 2 degrees Celsius will require not only reducing emissions of carbon dioxide, but also active removal of carbon dioxide from the atmosphere. This conclusion from the Intergovernmental Panel on Climate Change has prompted heightened interest in "negative emissions technologies."

Last summer, my daughter and I hiked the Sulphur Skyline trail in Jasper National Park. As it was mid-week, we had hoped it would not be as crowded as it can be on a weekend.
