Global Climate Change and Its Impacts

and property, and reduced economic losses from flood disasters. In drought-prone regions,
international funds primarily focus on investing in irrigation facilities to ensure agricultural
water supply. Through constructing large irrigation reservoirs and deploying high-efficiency
water-saving irrigation pipelines, these initiatives have improved water resource utilization
efficiency, effectively alleviated climate change impacts on agricultural production, and en-
sured food security.
However, it cannot be overlooked that current international funding support has re-
vealed issues of insufficient effectiveness and targeting during actual implementation. In the
fund allocation process, the lack of scientific, rational, and widely recognized standards has
resulted in countries with high greenhouse gas emissions, low economic development levels,
severe climate change impacts, and urgent funding needs failing to receive funds commen-
surate with their actual requirements, while some nations experience idle funds or inefficient
utilization.
For instance, in certain countries that received international funding, unreasonable proj-
ect planning and insufficient execution capacity have led to funds lying idle in accounts for
extended periods, failing to be timely invested in climate change response projects, resulting
in resource waste.To genuinely enhance the effectiveness and targeting of financial support,
the top priority is to establish a fund allocation evaluation system based on developing coun-
tries’ actual needs and climate action progress. This system should comprehensivelyconsid-
ermultiple key factors, including a country’s greenhouse gas emissions—where nations with
higher emissions bear greater responsibilities in emission reduction tasks.The greater the
pressure, the more funding is required for emission reductiontechnologiesR&D and project
implementation; the level of economic development - economically disadvantaged coun-
tries often lack sufficient funds to address climate change and should receive more financial
support; the degree of climate change impact - countries frequently affected by extreme
climate events such as floods,droughts, hurricanes, etc., require substantial funding to build
climate-resilient infrastructure and implement disaster response projects. Through compre-
hensive assessment of these factors, funds can be precisely allocated to ensure they flow to
countries and projects most in need. Simultaneously, it is crucial to strengthen whole-process
supervision of fund utilization, establish strict fund usage reporting systems and audit mech-
anisms, guarantee that funds are specifically dedicated to climate change response projects,
enhance funding efficiency, and maximize the benefits of every allocation.
(2) International Technical Support Mechanisms
International technical support is of paramount significance for developing countries
to break through technological bottlenecks and achieve a leapfrog improvement in their
climate change response capabilities. In key areas such as renewable energy technologies,
energy-saving and emissionreduction technologies, there exists a significant gap between
developing and developed countries. This technological gap severely constrains the opera-
tional capabilities and effectiveness of developing countries in addressing climate change.
