Summary
China
Area of Science:
- Environmental Science
- Urban Planning
- Sustainable Development
Background:
- Coordinating new urbanisation and carbon emissions (NU-CE) is vital for sustainable urban planning in China.
- Understanding the temporal and spatial dynamics of NU-CE coupling is crucial for effective policy development.
Purpose of the Study:
- To evaluate the past and future coordination states of new urbanisation and carbon emissions in China.
- To analyze the spatio-temporal evolution characteristics of the NU-CE coupling relationship across 30 provinces.
- To propose policy recommendations for enhancing NU-CE coordination.
Main Methods:
- An improved coupling coordination degree (CCD) model was utilized.
- Spatial auto-correlation analysis was employed to assess spatial dependencies.
- Grey GM(1,1) prediction model forecasted future CCD trends.
Main Results:
- New urbanisation levels are rising with significant spatial heterogeneity, concentrated in eastern coastal areas.
- Carbon emissions show slight fluctuations with regional disparities, lowest in Shanxi and Inner Mongolia.
- NU-CE coupling coordination degree continuously improved, exhibiting a declining pattern from east to west.
- Positive spatial correlation in NU-CE CCD was observed, with high-high clusters shifting centrally and low-low clusters moving northwestward.
- Future predictions indicate a growing trend in NU-CE coordination and strengthening spatial correlations.
Conclusions:
- China's NU-CE systems demonstrate improving coordination, albeit with persistent spatial inequalities.
- Policy interventions should address regional differences to foster balanced low-carbon urbanisation.
- Future trends suggest enhanced coordination, necessitating proactive strategies for sustainable urban development.

01:50Global Climate Change
24.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:14The Carbon Cycle
39.4K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

01:23Insulation Coordination
215
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times...
