We Need To Speak Out Against Policies That Are Exacerbating Climate Change

Governments worldwide are increasingly undermining efforts to tackle climate change, despite mounting scientific evidence of its severe impacts on human health and the environment. A recent report from the US National Academies of Sciences, Engineering, and Medicine highlighted the clear dangers posed by greenhouse gases such as carbon dioxide and methane. However, the US Environmental Protection Agency (EPA) has moved to rescind its 2009 Endangerment Finding, which classified these emissions as pollutants harmful to public welfare, signalling a rollback of crucial climate regulations. This regulatory backsliding, largely influenced by fossil fuel industry lobbying, threatens to stall progress on reducing emissions and addressing the climate crisis. The consequences of climate change are becoming increasingly visible, with extreme weather events growing in frequency and intensity across the globe. March 2026 was recorded as the second-warmest March since 1850, illustrating the accelerating pace of global warming. Compounding the problem, meteorologists in the US face challenges in forecasting severe weather due to reduced data collection from weather balloons, which are critical for accurate predictions. Interruptions in these data streams hinder the ability to provide timely warnings, leaving communities more vulnerable to sudden and devastating storms. Agriculture, a vital sector for global food security, is also deeply entwined with climate issues, particularly through its reliance on energy-intensive fertilisers. Nitrogen-based fertilisers, predominantly produced using fossil fuels, contribute significantly to greenhouse gas emissions, including nitrous oxide. New low-carbon production methods offer promising alternatives, potentially reducing emissions and decoupling fertiliser supply from fossil energy. Emphasising circular agricultural practices, such as composting and biological crop protection, alongside empowering local farmers, could enhance sustainability and resilience within food systems. Marine ecosystems are similarly affected by warming oceans, with species such as southern right whales serving as indicators of environmental stress. Research indicates that shifting feeding grounds and declining prey availability, driven by rising sea temperatures, are impacting the reproductive success of these whales in regions like Western Australia. This decline underscores the broader ecological consequences of climate change, highlighting the interconnectedness of species survival and habitat conditions. Finally, the scientific community faces significant challenges due to funding cuts and political interference, which jeopardise ongoing research crucial for understanding and mitigating climate change. The departure of key researchers and reduced support for environmental studies threaten to limit the evidence base needed for informed policy decisions. Without sustained investment in science, efforts to address climate change and its multifaceted impacts risk being severely compromised.
