Global Climate Change and Its Impacts

and social adaptation strategies through surveys and case studies. In some developing coun-
tries, residents in impoverished areas are often more vulnerable to climate shocks, such as
droughts causing crop failures that threaten food security. Social groups with different cultur-
al backgrounds also exhibit variations in their perceptions and responses to climate change.
Challenges persist when integrating climate science with sociological theories and meth-
odologies. Sociological research emphasizes the complexity of individual/group behaviors
and sociocultural influences, differing from traditional climate science approaches rooted in
physical laws. To achieve effective integration, mixed research methods combining quanti-
tative climate data analysis with qualitative sociological investigations should be adopted.
Establishing interdisciplinary platforms to facilitate joint participation of climate scientists
and sociologists in research projects will enable multidimensional analysis of climate issues
and propose comprehensive solutions.

Data Quality and Sharing Issues in Climate Change Research

Data quality and sharing play a crucial role in climate change research. High-quality
data forms the foundation for accurately understanding climate change processes, building
reliable models, and formulating effective policies. However, numerous challenges exist in
data quality control within climate change research. Observational data may be affected by
instrument errors, changes in observation environments, and human operational errors. For
instance, temperature sensors at weather stations might experience aging due to prolonged
use, leading to inaccurate measurements. In ocean observations, seawater salinity measure-
ments can be compromised by issues such as inaccurate sensor calibration and biofouling. To
ensure data quality, rigorous data quality control processes must be established. This includes
regular calibration and maintenance of observation instruments, along with standardized
protocols for data collection and processing. Data verification and cross-validation methods
should be employed, using multiple observation techniques to mutually corroborate data and
enhance reliability. Concurrently, uncertainty assessments should be conducted to clarify er-
ror margins in the data, providing references for subsequent analysis and applications.
Data standardization is also a crucial component in climate change research. Due to
variations in data formats, units, and temporal resolution among datasets collected by dif-
ferent regions and institutions, significant challenges arise in data integration and analysis.
Establishing unified data standards can facilitate the global sharing and utilization of climate
change data. Under the framework of the Global Climate Observing System (GCOS), stan-
dardized specifications for meteorological, oceanic, and terrestrial observation data have
been developed, including requirements for data formats and metadata descriptions. By ad-
hering to these standards, nations and institutions can more efficiently exchange and share
data, thereby enhancing data compatibility and usability.
Establishing effective data sharing mechanisms is crucial for promoting global collabo-
ration in climate change research. While several international data sharing platforms current-
