Simulating 195 million years of global climate in the Mesozoic

The Mesozoic, which stretched from about 252 million to 66 million years ago, was a pivotal period in Earth's history. In addition to being the age of the dinosaurs, it was when the supercontinent Pangaea began to separate into the fragmented continents we're familiar with today. Together with elevated levels of carbon dioxide and the brightening Sun, tectonic changes influenced the global climate, producing warm and humid greenhouse conditions. A detailed understanding of the factors that drove Mesozoic climate trends will not only provide insight into Earth's history but also help scientists study the consequences of human-caused warming of our planet.

Decline in CO2 cooled Earth's climate more than 30 million years ago

New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2.

New pathway to mitigate climate change and boost progress on UN Sustainable Development Goals

A world that combats climate change while simultaneously improving on all 17 Sustainable Development Goals (SDGs) is possible, a new study finds. Scientists from the Potsdam Institute for Climate Impact Research (PIK) and the German Development Institute have developed a new integrated strategy that combines ambitious climate action with dedicated policies for development, food and energy access, global and national equity, and environmental sustainability. It sheds new light on bottlenecks, but also synergies for boosting progress towards climate and sustainable development targets.

Are women climate scientists judged for speaking out? Not so much, research suggests

Many scientists are likely to be invited for media appearances in the run up to COP26, the international negotiations on global heating that will take place in Glasgow in November 2021. Journalists will ask climate scientists to help place the talks in context and to discuss the value of particular options for reducing emissions, or to explain how climate change may have contributed to particular weather events. Given the exposure these opportunities afford, it’s no surprise that some climate scientists take the chance to lend their support to particular measures.

Climate crisis could kill 83 million people by 2100, study finds

The climate crisis would cause an estimated 83 million excess deaths by 2100, according to a new study. The research paper, published on Wednesday, uses a new metric called the “mortality cost of carbon” to estimate the number of deaths caused by the emissions from putting one additional metric ton of carbon dioxide (CO2) into the atmosphere.

To fight climate change, don't neglect agricultural R&D

With the Senate's recent vote to advance the $1 trillion bipartisan infrastructure deal - a deal limited to "hard" infrastructure like roads, railways and bridges - advocates for climate action are shifting their sights to a budget reconciliation bill. By bypassing the filibuster, reconciliation would provide Democrats with the opportunity to accomplish many of the Biden administration's more ambitious and partisan priorities. In all the excitement, however, agricultural research and development - a crucial climate mitigation strategy - is at risk of being overlooked.

An English castle stood for centuries. Climate change prompted its collapse.

KEYHAVEN, England - Fearful of a French invasion after breaking with Rome, Henry VIII erected a line of massive coastal forts along the English Channel, and one of the most imposing is called Hurst Castle. It has stood on its sandy spit since 1544, through the Napoleonic Wars and World War II. Its garrison protected the Allied forces on D-Day.
