Rising ocean temperatures are driving great white sharks further north than ever recorded, with experts warning they are already visiting UK waters. Climate change is forcing shifts in marine habitats, potentially paving the way for tropical species like hammerheads.
The UK is experiencing its third heatwave of the year, with temperatures exceeding 35C and record-breaking heat across Europe. Health services are strained, schools closed, and businesses like supermarkets face operational challenges due to extreme heat.
The UK is experiencing an "extreme" marine heatwave with ocean temperatures 2C warmer than usual, potentially causing mass-mortality events for marine species. Scientists link this to Europe's recent heat dome and El Niño conditions, warning of significant ecosystem disruption.
Sydney's famed surf breaks are overshadowed by fear following a spate of shark bites, including a critical injury to Leah Stewart. Experts like Rob Harcourt and Daryl McPhee cite rising trends, influenced by warming waters and increased seal populations, while questioning the efficacy of traditional shark control measures.
El Nino has set in, according to the European weather agency, with Pacific Ocean temperatures crossing the 0.5°C threshold, likely to impact global weather and the Indian monsoon.
Kiribati derives over 70% of government revenue from selling tuna fishing licenses to foreign fleets, the highest proportion of any nation. The country's EEZ of 3.4 million sq km generates $137m annually, but climate change threatens to push tuna eastward to cooler waters, potentially costing more than $10m per year by 2050 under high emission scenarios.
