Climate change and the Trump presidency

Donald Trump has said that no-one really knows whether climate change is real. Scientists tend to disagree. But what will the new presidency have in store for the US approach to climate change? read more

expert reaction to study of the growth rate of atmospheric CO2

A pause in the growth rate of carbon dioxide in the atmosphere is reported in the journal Nature Communications with the researchers also reporting a decline in the fraction of man-made emissions remaining in the atmosphere despite an increase in the levels of those emissions. read more

The state of the climate

This time last year, climate scientists came to the SMC to brief journalists ahead of the Paris negotiations. As the next COP meeting in Marrakesh approaches, those same scientists talked about the latest in climate science. What do the most recent observations show and has anything significantly changed? What trajectory are we on, and is the policy response in step with the science? What are scientists expecting to happen to temperatures and the earth’s response to greenhouse gases? And are we moving fast enough with clean energy technologies? read more

pause in Antarctic Peninsula warming

The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. The stabilisation of the ozone hole, changing wind patterns and natural variability were significant in bringing about this change. Together these factors have caused the peninsula, which makes up 1% of the Antarctic, to enter a temporary cooling phase. Temperatures remain higher than measured during the middle of the 20th Century, so glacial retreat is still taking place. Scientists predict that if greenhouse gas concentrations continue to rise at the current rate, temperatures will increase across the Antarctic Peninsula by several degrees Centigrade by the end of this century. read more
