In recent years, the rapid development of the global economy has led to an increasing impact of the ongoing climate warming phenomenon on the hydrological cycle. In this context, the runoff changes affected by human activities are more severe. This study classifies climate scenarios based on carbon emission levels into "low-carbon" (SSP1-2.

Introduction: There is increasing prevalence of single-use flexible laryngoscopes in Otolaryngology. This study aims to quantify and compare the environmental outcomes of single-use disposable flexible laryngoscopes (SUD-Ls) and reusable flexible laryngoscope (R-Ls).
Methods: The ISO 14040 standardized Life Cycle Assessment (LCAs) was utilized to estimate the environmental footprint of SUD-L and R-L.
Deciphering the Vulnerability of Pollen to Heat Stress for Securing Crop Yields in a Warming Climate.

Climate change is leading to more frequent and severe extreme temperature events, negatively impacting agricultural productivity and threatening global food security. Plant reproduction, the process fundamental to crop yield, is highly susceptible to heatwaves, which disrupt pollen development and ultimately affect seed-set and crop yields. Recent research has increasingly focused on understanding how pollen grains from various crops react to heat stress at the molecular and cellular levels.

To clarify the characteristics of greenhouse gas emissions （CO, CH, and NO） and the comprehensive greenhouse effect from vegetable fields with different organic planting years, the differences in greenhouse gas emission flux, emission intensity （GHGI）, and warming potential （GWP） and their influencing factors among vegetable fields with different organic planting years in Songhuaba, including 10 years, 6 years, 3 years, and conventional planting, were analyzed. The results showed that the CO emissions from organic planting treatments were higher than those from conventional planting, whereas the NO and CH emissions were the opposite. Compared to those from conventional planting, the CO emission fluxes and cumulative emissions from organic cultivation for 10, 6, and 3 years increased by 121.

The wastewater treatment industry is an energy-intensive industry and one of the main sources of high warming potential greenhouse gases （GHG） such as CH and NO. The GHG reduction in this industry is an important part of achieving global climate goals. In 2019, there were 4 359 urban wastewater treatment plants in China, with a total wastewater treatment volume of 63.
