As world leaders convene for the UN climate summit in Brazil, the situation regarding climate change remains dire. Despite decades of discussions and commitments, greenhouse gas emissions have surged by a third since the first climate conference, and fossil fuel use continues to increase. This trend poses a significant threat, as global temperatures are expected to exceed critical limits, leading to potentially catastrophic consequences. The urgency for effective cooperation in addressing climate change has never been more pressing.

A recent study reveals that climate change significantly contributed to the rapid intensification of Hurricane Melissa, making it six times more likely to occur. This finding highlights the urgent need to address climate change, as it not only affects weather patterns but also increases the severity of natural disasters, impacting communities and ecosystems.

A recent Lancet report highlights a concerning rise in heat-related deaths, now at 546,000 annually, due to increasing global temperatures. In an insightful discussion with Emilia Carrera from the Rockefeller Foundation, we explore how cities can take proactive steps to mitigate these impacts and safeguard the health of their residents. This conversation is crucial as urban areas face unique challenges from climate change, making it imperative for city planners and policymakers to prioritize health in their climate strategies.

A recent study from the University of Queensland warns that the Great Barrier Reef is facing a 'grim future' with rapid coral decline expected over the next few decades due to global heating. However, the research also suggests that if global temperature rise is limited to 2 degrees Celsius, there is still a chance for recovery. This finding is crucial as it highlights the urgent need for climate action to protect one of the world's most iconic ecosystems, emphasizing that our choices today can significantly impact the reef's future.
