Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

Until then, it would appear that it is your assertion that the carbon dioxide filled bottle heated faster and become hotter than the air filled bottle because the carbon dioxide has a higher mass than does air, i.e., «Much smaller mass means they can hold much less heat, just as a smaller cup holds less boiling water.»

During extreme heat events, nighttime temperatures in the region's big cities are generally several degrees higher28 than surrounding regions, leading to increased heat - related death among those less able to recover from the heat of the day.36 Since the hottest days in the Northeast are often associated with high concentrations of ground - level ozone and other pollutants, 37 the combination of heat stress and poor air quality can pose a major health risk to vulnerable groups: young children, the elderly, and those with pre-existing health conditions including asthma.29 Vulnerability is further increased as key infrastructure, including electricity for potentially life - saving air conditioning, is more likely to fail precisely when it is most needed — when demand exceeds available supply.

You are probably also aware already that water vapor is as much if not more of a so called greenhouse gas than carbon dioxide is and there is a lot of evaporating ocean water on the planet not to mention clouds and high tropical humidity because hot air provides added space in the atmosphere for water vapor gas to become a major component of air.
