Almost every country in the world has signed up to the Paris Agreement’s goal of keeping warming well-below 2C and pursuing efforts to limit it to 1.5C.
This Southern Ocean warming and its associated impacts are effectively irreversible on human time scales, because it takes millennia for heat trapped deep in the ocean to be released back into the atmosphere. This means changes happening now will be felt for generations to come – and those changes are only set to get worse, unless we can stop carbon dioxide emissions and achieve net zero.
Greenland’s vast ice sheet is undergoing a surge in melting, with the amount of ice vanishing in a single day this week enough to cover the whole of Florida in two inches of water, researchers have found.
Scientists just completed one of the most comprehensive investigations of Earth’s climate history—and the findings aren’t favorable. They found that the planet could eventually warm to levels it hasn’t reached in at least 34 million years.

The climate crisis is damaging the mental health of hundreds of millions of people around the world but the huge costs are hidden, scientists have warned. Heatwaves are increasing rates of suicide, extreme weather such as floods and wildfires are leaving victims traumatised, and loss of food security, homes and livelihoods is resulting in stress and depression. Anxiety about the future is also harming people’s mental health, especially the young, the scientists said in a report.
1.5 °C scenarios reported by the Intergovernmental Panel on Climate Change (IPCC) rely on combinations of controversial negative emissions and unprecedented technological change, while assuming continued growth in gross domestic product (GDP). Thus far, the integrated assessment modelling community and the IPCC have neglected to consider degrowth sce- narios, where economic output declines due to stringent climate mitigation. Hence, their potential to avoid reliance on negative emissions and speculative rates of technological change remains unexplored. As a first step to address this gap, this paper compares 1.5 °C degrowth scenarios with IPCC archetype scenarios, using a simplified quantitative repre- sentation of the fuel-energy-emissions nexus.

The number of countries announcing pledges to achieve net zero emissions over the coming decades continues to grow. But the pledges by governments to date – even if fully achieved – fall well short of what is required to bring global energy-related carbon dioxide emissions to net zero by 2050 and give the world an even chance of limiting the global temperature rise to 1.5 °C.
Scientists say ice equivalent to 1-2 metres of sea level rise is probably already doomed to melt
Where it’s no longer credible to deny climate change, the fossil fuel giant puts the focus on ‘risk’ and blame on consumers, in echo of tobacco industry PR, researchers find.

The framing of climate change, in particular, as something that wouldn’t be an issue if “we” had all just made better consumer choices has been persistent and effective. Every Earth Day, we’re bombarded with tips about how to minimize our personal carbon footprints; meanwhile, it’s 2021 and the GOP is still suggesting tree-planting as climate policy.
