Brazil at a Crossroads
The report argues that Brazil's plan to increase oil and gas production by 20% by 2030, largely driven by Petrobras, carries significant economic and climate risks. It finds that a majority of Petrobras' new projects would be economically unviable in a 1.5°C warming scenario and recommends that the government curb expansion, redefine Petrobras' mandate toward a transition plan, and redirect investment to avoid potential stranded asset losses of USD 13 to 36 billion.

CoastalDEM v2.1 A New, High-Accuracy and High-Resolution Global Coastal Elevation Model Trained on ICESat-2 Satellite Lidar
CoastalDEM v2.1 is a near-global digital elevation model (DEM) developed by Climate Central to provide more accurate land elevation data for coastal flood risk assessments. By utilizing a sophisticated convolutional neural network trained on NASA's ICESat-2 satellite lidar data, the model corrects the positive vertical bias common in satellite radar-derived DEMs, which often mistake building rooftops for ground level. Testing shows that CoastalDEM v2.1 virtually eliminates global median bias in the critical 0 to 5 m elevation band, significantly outperforming other publicly available global DEMs such as NASADEM, TanDEM-X, MERIT, and AW3D30, particularly in densely populated urban areas.
