As scientific terms go, “climate change” is failing. Good terms are specific, descriptive and help people to understand complex concepts. Climate change is ambiguous, referring perhaps to the most pressing human-generated environmental problem of the century, or to other kinds of changes that happen through natural forces and have been going on since long before humans arose.Last week I chatted with Columbia University paleontologist Dennis Kent about some new work he and his colleagues published in the Proceedings of the National Academy of Sciences about the surprisingly big influence of Venus and Jupiter on the climate of Earth. The gravitational tug of the second and fifth planets from the sun act to stretch Earth’s annual orbit like a rubber band, pulling it into a more oblong ellipse and then back to something very close to a perfect circle over a cycle of 405,000 years. And that leads to big changes in our climate – or the climate of whatever creatures … [Read more...] about Inspiring Terms Are Simple. ‘Climate Change’ Isn’t.

The Captain's log book from an old sailing ship may hold the key scientists need to understanding climate change in our region. Scientists are now poring over the records of a journey to the Antarctic that took place 84 years ago. In 1935, the Discovery II was unknowingly writing its own page in the history books through its log book. Antarctica's past key to our future The battle against blizzard like conditions to restore Hillary's history Opinion : Frozen in time in Captain Scott's Antarctic hut NIWA is a part of an international data collection group that is taking data like the Discovery's and putting it into international databases so past climate can be reconstructed. "Around New Zealand obviously there's a lot of ocean so there's no climate station in the ocean, so a huge resource of data that's just beginning to be tapped into is ship's log books," climate scientist Petra Pearce told Newshub. "We're just starting to uncover millions, there's millions, … [Read more...] about Battle against climate change turns to historic ship’s log books
The man chosen by Donald Trump to be the new head of Nasa is a “climate change denier” who has “made a career out of ignoring science” and might disregard scientific advice about the safety of launching astronauts into space, US senators have warned. Giving Tea Party Congressman James Bridenstine the final say on whether to launch a manned space mission would, it was claimed, be “terrifying”. But Mr Bridenstine was still confirmed in the job this week in a vote that split 50-49 along party lines - in contrast to the unanimous senatorial approval granted to all 12 previous Nasa leaders. Read more Every mention of global warming deleted from White House website The confirmation of Mr Trump’s nominee came despite Mr Bridenstine telling Congress in 2013 that “global temperatures stopped rising ten years ago. Global temperature changes – when they exist – correlate with sun output and ocean cycles.” Not only did … [Read more...] about Trump’s new Nasa chief Jim Bridenstine a ‘climate change denier’ who could make ‘terrifying’ decisions, US senators warn
Story highlights Hunter-gatherers survived abrupt climate change events Data combined human activity and climate record analysis Climate change would impact modern lives in different ways, expert says (CNN)Imagine if, instead of heat this summer, we were faced with a sudden, dramatic cold front that lasted the next 100 years. That is what our hunter-gatherer ancestors lived through 11,000 years ago. Findings from a Middle Stone Age site named Star Carr in North Yorkshire, England, show that our ancestors resiliently survived the century-long drop in temperature, according to a new study in the journal Nature Ecology & Evolution on Monday. How they responded to such abrupt climate change could hold key insights for us as we face a different kind of climate change, the researchers said. Ancient climate change Paleoclimatologists, who study climates of the past, know that Earth's climate was not as stable for our ancestors as it has been for us.

0 Have your say Throughout my seven years with Christian Aid, working to mitigate and adapt to the impact of climate change in Latin America and the Caribbean, I am always struck by the resilience and commitment of our local partners. No matter how much they try to bring about lasting change, they face seemingly constant knock-backs as weather patterns become more unpredictable. Last year, hurricane after hurricane threatened to unleash destruction on Central America and the Caribbean, including El Salvador. Each time a new hurricane was announced, be it Irma, José, Katia or Maria, I felt anxious about my colleagues and our local partner organisations, as these are my climate heroes and heroines, Christian Aid’s climate champions. I especially remembered the words of Carolina Amaya, who works at our partner organisation UNES (the Salvadoran Ecological Unit): “There is no plan B. There is no planet B.” But … [Read more...] about Gaby Drinkwater: Climate change needs a big shift in thinking – some nations can’t wait
