Antarctica's Ice Shelves Shrinking Fast: Key Climate and Nature Updates - Week in Review

Antarctica's Ice Shelves Melting: Weekly Climate and Nature Highlights

Discover the most crucial updates from the realm of climate and nature over the past week.

1. Over 40% of Antarctica's Ice Shelves Melted Since 1997

Recent findings reveal that more than 40% of Antarctica's ice shelves have undergone significant shrinkage since 1997, largely due to the consequences of climate change. According to researchers from the University of Leeds, a concerning aspect is that half of these ice shelves show no signs of recovery. This investigation reports a substantial loss of 7.5 trillion tonnes of ice between 1997 and 2021, with 67 trillion tonnes melting in the west while 59 trillion tonnes were added to the east. The culprit, as explained by Dr. Benjamin Davison, lies in the varying ocean temperatures and currents around Antarctica.

2. Crucial Methane Emission Cuts Urged to Combat Global Warming - IEA

A groundbreaking report from the International Energy Agency (IEA) underscores the vital importance of reducing methane emissions from fossil fuels. Surprisingly, the report suggests that swift cuts in methane emissions could have a more significant impact on the fight against climate change than removing all cars and trucks from the road. Reducing methane emissions could potentially prevent a temperature increase of up to 0.1 °C by mid-century. Methane is responsible for nearly 30% of the global temperature rise since the Industrial Revolution, and the IEA estimates that existing technologies could avoid over 80 million tonnes of annual methane emissions by 2030.

3. Climate Change Disrupts the World's Water Cycle - Key Insights

Human-induced climate change is unsettling the global hydrological cycle, a comprehensive report from the World Meteorological Organization (WMO) reveals. The "State of Global Water Resources 2022" report emphasizes the need for significant policy shifts, improved monitoring, data sharing, cross-border collaboration, and increased investments to manage the repercussions of extreme conditions.

4. Other Noteworthy Climate and Nature Developments

- A study shows that extreme weather has cost the world a staggering $16 million per hour over the last two decades, including losses from storms, floods, heatwaves, and droughts.

- Scientists warn that almost half of the world's known flowering plants, including vital crop species, are at risk of extinction. Additionally, over 2 million species of fungi remain unidentified.

- Natural disasters and extreme weather events cost China $42 billion in direct economic losses during the first nine months of 2023.

- A plausible increase in extreme weather events could lead to global economic losses of up to $5 trillion, according to Lloyd's of London.

- The indigenous communities of the Amazon call upon the Brazilian government to declare a climate emergency as drought plagues their villages, resulting in water, food, and medicine shortages. This aligns with the findings of World Weather Attribution, which attributes South America's recent heatwave to global warming.

5. Exploring More on the Climate Crisis

- Plastic pollution remains a pressing challenge in the ASEAN region, with an annual generation of over 31 million tonnes of plastic waste in six out of ten ASEAN countries. Collaborative efforts among governments, businesses, and civil society are essential to tackle this crisis.

- Carbon removal is imperative for businesses to achieve net zero emissions. Investment in carbon removal is critical, and digital MRV (Monitoring, Reporting, Verification) systems enable businesses to take immediate action.

- Carbon Brief investigates the Royal Botanic Gardens, Kew, research on habitat loss and climate change as primary extinction risks for plants and fungi, presenting five key findings from the "State of the World’s Plants and Fungi" report.
