Summary
Climate heterogeneity significantly impacts transportation CO2 emissions in cold regions. Targeted energy-saving strategies, like reducing energy intensity, are crucial for peaking emissions by 2028.
Area of Science:
- Environmental Science
- Energy Policy
- Transportation Engineering
Background:
- Climate heterogeneity significantly impacts transportation CO2 emissions, particularly in cold regions due to high energy consumption for heating and low electric vehicle adoption.
- Cold regions face unique challenges in reducing transportation carbon dioxide (CO2) emissions, necessitating region-specific strategies.
- Addressing these challenges is vital for achieving early CO2 emission peaks in the transportation sector.
Purpose of the Study:
- To predict the CO2 emission trends of the urban transportation sector in a typical cold Chinese province.
- To propose targeted emission reduction measures for peaking CO2 emissions as soon as possible in cold regions.
- To evaluate the effectiveness of different emission control scenarios.
Main Methods:
- Construction of an integrated Long-range Energy Alternatives Planning (LEAP) system model.
- Incorporation of multi-transportation modes and multi-energy types within the LEAP model.
- Simulation of five distinct emission control scenarios for future trends (2017-2050).
Main Results:
- Projected CO2 emission peaks range from 704.7 to 742.1 thousand metric tons (TMT) between 2023 and 2035.
- The Energy-saving-low-carbon scenario (ELS) is identified as optimal, with a peak of 716.6 TMT in 2028.
- Decreasing energy intensity is the most dominant factor in reducing CO2 emissions, followed by increasing public transport and reducing fossil fuels.
Conclusions:
- Energy intensity reduction is the primary strategy for mitigating CO2 emissions in cold region transportation.
- The ELS scenario offers a viable roadmap for achieving early CO2 emission peaks.
- Findings provide a practical reference for other cold regions to formulate effective CO2 reduction strategies.

01:27Frost Action on Concrete
162
Concrete structures in cold climates, such as those along roadsides, can retain moisture. This moisture makes them susceptible to frost-related damage when temperatures fall below freezing. Adding moisture worsens the damage during temperature fluctuations, leading to repeated freezing and thawing. De-icing salts, spread over these structures to melt ice, add to the freeze-thaw cycle, and draw even more moisture into the concrete.

01:50Global Climate Change
24.9K
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.

01:27Cold Weather Concreting
122
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.

142
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

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...
