Cyclical climate change refers to natural fluctuations in the Earth's climate that occur over long periods, often driven by factors such as solar radiation, ocean currents, and volcanic activity. These cycles can include glacial and interglacial periods, which significantly impact global temperatures and weather patterns. While human activity has accelerated recent climate change, understanding these natural cycles is essential for contextualizing current changes in the climate system.

Climate significantly influences the rate of limestone weathering, primarily through temperature and precipitation levels. In warmer and wetter climates, chemical weathering processes, such as carbonation, are accelerated, leading to faster dissolution of limestone. Conversely, in colder or drier climates, the rate of weathering typically slows down due to reduced moisture and lower temperatures. Additionally, variations in humidity can impact biological activity, further affecting limestone erosion rates.

The climate in the Llano Uplift, located in central Texas, is characterized as a humid subtropical climate. It experiences hot summers with temperatures often exceeding 90°F (32°C) and mild winters, with average lows around the 30s°F (-1 to 4°C). Rainfall is moderate, averaging about 30-40 inches annually, with the majority occurring in spring and early summer. The region can also experience occasional droughts, as well as severe weather events like thunderstorms and tornadoes.

The impact of climate on Nubians differs significantly due to their geographical location and lifestyle. Nubians, primarily residing along the Nile in northern Sudan and southern Egypt, have historically adapted to the arid desert climate through agriculture reliant on seasonal flooding of the Nile. In contrast, climate impacts in other regions may involve more diverse ecosystems and agricultural practices, often influenced by varying rainfall patterns and temperature changes. Thus, the Nubians' adaptation strategies are specifically tailored to their unique environmental conditions.

Several factors do not contribute to Earth's climate, including the presence of artificial satellites in orbit, specific human-made structures, and isolated local events like a single volcanic eruption. Additionally, short-term weather phenomena, such as a temporary rainstorm or a heatwave, do not influence the long-term climate patterns. Lastly, the Earth's internal heat from radioactive decay has a minimal impact on climate compared to external factors like solar radiation and atmospheric composition.
