Scientists propose guidelines for solar geoengineering research
Solar geoengineering has been proposed as a way to block solar radiation with sulfur particles, much as volcanic eruptions have done. An international team of scientists led by the NSF NCAR has published a paper proposing specific guidelines for evaluating stratospheric aerosol intervention (SAI) research, emphasizing the need to assess both the technical feasibility and potential ecological and societal impacts of injecting sulfur dioxide into the stratosphere to cool Earth by reflecting incoming solar radiation. The new paper outlines eight comprehensive research criteria for assessing SAI developments including monitoring by satellite observations validated with in situ measurements, and recommends regular, globally representative assessment reports. The purpose is to provide policymakers and the public with the best possible scientific understanding of this controversial geoengineering approach.

The Great Barrier Reef waters were the warmest in 400 years over the past decade, Australian study finds
Ocean temperatures around the Great Barrier Reef have surged to their highest levels in 400 years resulting in severe coral bleaching events. Reconstructed sea surface temperature data from 1618 to 1995 coupled with sea surface temperature data from 1900 to 2024 demonstrate that this exceptional thermal stress over the last decade, attributed to anthropogenic climate change, jeopardizes the reef's survival. The study suggests significant threats to global coral reefs as they approach critical warming thresholds.

New Data Show U.S. Oil & Gas Methane Emissions Over Four Times Higher than EPA Estimates, Eight Times Greater than Industry Target
New aerial measurements from MethaneAIR indicate that U.S. oil and gas producers are emitting methane at rates over four times higher than EPA estimates and eight times above their own emissions targets, highlighting a critical need for accurate emissions data collection and reporting. This new data will inform policy and regulatory developments, particularly as the EPA updates its reporting program to incorporate advanced measurement technologies such as satellite observations, ensuring transparency and accountability in emissions management.

Antarctic temperatures soar 50 degrees above norm in long-lasting heat wave
East Antarctica is experiencing an extraordinary heat wave, with temperatures soaring over 50 degrees F (28°C) above average marking the region's second such event in just two years. Antarctic warming is progressing at twice the average global rate, raising concerns that these extreme temperature anomalies will occur more frequently, destabilizing critical polar systems like sea ice and atmospheric circulation which are essential for regulating global climate patterns.

New Zealand’s sea temperatures hit record highs, outstripping global averages
New Zealand's sea temperatures have surged to record highs, with some regions experiencing warming rates three times higher than the global average. This unprecedented increase in ocean temperatures, measured to be double the global per-decade average, highlights significant changes in marine conditions around the island nation.

Category 5 Hurricane Beryl makes explosive start to 2024 Atlantic season
Hurricane Beryl's record-setting rapid intensification to Category 5 in early July, 2024 highlights the importance of long-term climate observations. This unusual early development, driven by record-warm ocean temperatures and changing atmospheric conditions, underscores the need for ongoing monitoring to understand and prepare for evolving hurricane patterns due to climate change.

Hawaii’s Mauna Loa Observatory just captured ominous signals about the planet’s health
Hawaii’s Mauna Loa Observatory reports that atmospheric CO2 levels are rising at an unprecedented rate, faster than observed over 66 years. CO2 levels are nearing 427 parts per million in the most recent readings, more than 50% above pre-industrial levels.

Record-breaking increase in CO₂ levels in world’s atmosphere
A record-breaking surge in atmospheric CO2 levels, driven by fossil fuel use and the recent El Niño, has alarmed scientists. The global average concentration in March increased by 4.7 ppm compared to March last year, an annual increase that has never been observed before.
