Summary: Although climate change affects diversification, its effects are inconsistent and less widespread than localized climate or species accumulation. This study focuses on highly speciose orchid subfamily and reveals that historic global cooling, not time or other climate factors, drives speciation in terrestrial orchids. With extensive data and analysis, the study demonstrates that global cooling played a significant role in contemporaneous diversification in all major orchid bioregions. This research provides valuable insights into the long-term impacts of global climate change on biodiversity.

Summary: The water tank heat storage system is mainly affected by the structural parameters of the water tank, while the phase change material heat storage system is more affected by the thermal performance parameters of the material itself. Thermochemical heat storage pays attention to both the material thermal performance parameters and the reaction bed structure parameters. Water tank heat storage is completely feasible in the global market, phase change material heat storage has a stronger application prospect in moderate climates compared to tropical climates, and thermochemical heat storage system could be economically feasible around 2030.
