Oregon says yes to coal-free electricity
Oregon says yes to coal-free electricity The Oregon legislature has adopted a first-in-the-nation plan to phase out electricity from coal, a major source of climate-changing greenhouse gases. The state’s environmental community had been gearing up for a ballot initiative this year that would have forced the state’s utilities to abandon coal as a fuel for electricity. But negotiations between […]
February’s global temperature spike is a wake-up call
February’s global temperature spike is a wake-up call Global temperatures for February showed a disturbing and unprecedented upward spike. It was 1.35℃ warmer than the average February during the usual baseline period of 1951-1980, according to NASA data. This is the largest warm anomaly of any month since records began in 1880. It far exceeds the records set […]
Can Geology Tell Us What is Warming the Climate?
Can Geology Tell Us What is Warming the Climate? On Monday this week, and rather late in the day, Dr Colin Summerhayes from the Scott Polar Institute, Cambridge University, left this lengthy comment at the end of the thread on Prof. Richard Lindzen’s post called Global Warming and the Irrelevance of Science. I wanted to respond to some of the […]
Food Insecurity: Arctic Heat Is Threatening Indigenous Life
Food Insecurity: Arctic Heat Is Threatening Indigenous Life Subsistence hunters in the Arctic have long taken to the sea ice to hunt seals, whales, and polar bears. But now, as the ice disappears and soaring temperatures alter the life cycles and abundance of their prey, a growing number of indigenous communities are facing food shortages. An […]
Meltdown Earth: the shocking reality of climate change kicks in – but who is listening?
Meltdown Earth: the shocking reality of climate change kicks in – but who is listening? Parts of the Arctic were 16℃ warmer than normal in February.

January 2016 broke the record for the largest monthly temperature anomaly. […]
In-depth: the scientific challenge of extreme weather attribution
In-depth: the scientific challenge of extreme weather attribution © Gene Blevins/LA Daily News Working out whether human activity is supercharging extreme events, such as floods, storms, droughts and heatwaves, is one of the youngest branches of climate science. But it’s moving at breakneck pace. So much so, that the US National Academy of Sciences has fast-tracked a report, […]
Global Warming and Food Prices
Global Warming and Food Prices Given that we all have to eat and that there are some concerning environmental developments out there, here’s an interesting question: has global warming led to higher or lower food prices (thus far)? As always the answer depends on how this affects the balance between supply and demand. Assuming that […]
Does Methane Threaten Life?
Does Methane Threaten Life? The question of whether methane (CH4) in the atmosphere is a threat to life is extraordinarily complex and generally not well understood. But, yes it is a serious threat, very serious and horribly real. Okay, but don’t scientists understand this, and why aren’t they speaking out? They are speaking out but […]
