Progress—and Room for Improvement—in UNEP’s Annual Report (United Nations Environment Programme)

How effective is the United Nations Environment Programme (UNEP)’s work on the fight against climate change? Its Annual Report analyzed the work it has done over the past year to do so. The UNEP supports key areas in which progress has been made, including waste reduction through the Global Framework on Chemicals and global instrument on plastic pollution, biodiversity protection efforts through various frameworks, and loss and damage mobilization through COP28.

UNEP’s “climate action” efforts include efforts to expand reporting and analysis, mitigate greenhouse gas emissions, aid community adaptation, generate finance, and revive water systems. Its “nature action” efforts include sustainable biodiversity governance and accountability, mainstreaming biodiversity, and countering desertification. The analysis also took in UNEP’s “pollution action” efforts included limiting—chemical, air, and plastic pollution. Across these three streams of activity, international cooperation, support of conflict-affected nations, and gender mainstreaming remain key priorities.

The new report also emphasizes which strides must be made in the near future to keep up the fight. The world’s greenhouse gas emissions were far above the amount necessary to limit global warming to 1.5C by 2030. Further, most of the Sustainable Development Goals remain far off track to match the 2030 agenda. Thus, the UNEP’s analysis emphasizes the dire need to accelerate progress faster than the climate crisis progresses.

Climate Security as a Key Concern in the Munich Security Report (Munich Security Council)

Before high-level officials met in mid-February at 2024’s Munich Security Conference, the event’s organizers produced the Munich Security Report, which outlined various security issues in several regions, as well as key cross-cutting issues. The report emphasized the need for collaboration rather than solely focusing on national interests across security concerns, including climate security.

The report emphasized four key points related to climate security. First, countries which prioritize their own national priorities risk hindering international climate cooperation. Additionally, competition between the U.S. and China can either spur innovation or hinder necessary cooperation. Transatlantic cooperation is likewise hindered by friction on subsidies and carbon prices which are meant to prioritize domestic interests. Finally, meaningful cooperation between high- and low- income countries is necessary to meet net-zero targets and align climate priorities, specifically when considering critical minerals and climate finance.

Balancing domestic interests with international cooperation with allies, adversaries, and emerging partners is a key theme throughout the report, and in the climate chapter specifically. It observes that policymakers must strike this delicate balance while strengthening domestic green industry and prioritizing key international partnerships. Doing so will ultimately reduce clean technologies’ vulnerability and meet global decarbonization goals as soon as possible to limit the impact of climate change.

Rain-on-Snow Events Create Devastating Environmental Impacts (Yale Environment 360)

Rain is not a common phenomenon in the Arctic, but with rising global temperatures over the past 20 years, it has become more frequent. Sea ice, glaciers, and, notably, Greenland’s ice cap, are impacted by these increased rates of rainfall, which alter and accelerate the melting process of snow and ice. So-called “rain-on-snow” events are understudied, but they may have devastating implications for sea level rise and local ecosystems.

Animals native to the region, including muskoxen, caribou, fish, and bird species, have been negatively impacted by the changes in climate. Not only is their existence necessary for the functioning of the Arctic ecosystem, but Indigenous peoples use their meat and byproducts for their survival and livelihoods.

As the issue worsens, it is becoming increasingly difficult to conduct research in the region. Half of the weather stations in Canada have been shut down, and there is a lack of researchers on the ground examining the impacts of rain on snow events on local species and communities. Past solely regional significance, any melting of the Greenland ice cap from rain-on-snow events or other causes will create an outsized impact on global sea levels.”
