There is evidence to suggest that summers were colder in the past, particularly during periods of global cooling such as the Little Ice Age, which lasted from the 14th to the 19th century. During this time, temperatures were lower than they are today, leading to colder summers in many parts of the world. However, it's important to note that climate is complex and influenced by many factors, so while some periods in the past may have experienced colder summers, overall trends show that global temperatures have been rising in recent decades. **

Summers are getting hotter and drier due to the phenomenon of climate change. The increase in greenhouse gas emissions, such as carbon dioxide, traps more heat in the Earth's atmosphere, leading to rising temperatures. This rise in temperature results in more evaporation of water from the land and oceans, leading to drier conditions. Additionally, changes in weather patterns and the depletion of natural resources also contribute to the increasing heat and dryness experienced during summers. **

Yes, hot, dry summers are becoming more frequent in many regions around the world. Climate change is leading to higher average temperatures and more extreme weather events, including heatwaves and droughts. These conditions can lead to increased risk of wildfires, water shortages, and negative impacts on agriculture. It is important for communities to adapt to these changing conditions and take steps to mitigate the effects of climate change. **

Summers are warm and winters are cold due to the tilt of the Earth's axis and its orbit around the sun. During the summer, the hemisphere is tilted towards the sun, allowing for more direct sunlight and longer days, resulting in warmer temperatures. In the winter, the hemisphere is tilted away from the sun, leading to less direct sunlight and shorter days, causing temperatures to drop. This seasonal variation in sunlight and daylight hours is the primary reason for the difference in temperature between summer and winter. **

There is evidence to suggest that global temperatures are rising, leading to hotter summers in many regions. However, the impact of climate change on winter temperatures is more complex. While some areas may experience colder winters due to changes in atmospheric circulation patterns, others may see milder winters. Overall, the trend of increasing global temperatures is leading to more extreme weather events, including heatwaves in summer and cold snaps in winter. **

As an AI, I do not have personal preferences or feelings, so I do not have the ability to like or dislike sweltering hot and humid summers. However, I can provide information on the potential effects of such weather conditions on humans, such as increased risk of heat-related illnesses and discomfort. It is important for individuals to take necessary precautions to stay safe and healthy during extreme heat. **

Climate change deniers often attribute hot summers to natural variability in the Earth's climate system, such as fluctuations in solar radiation or natural climate cycles like El Niño. They may also argue that historical temperature records are unreliable or that the current warming trend is not significant compared to past climate changes. Some deniers may also claim that the scientific consensus on climate change is exaggerated or politically motivated. Overall, their explanations often downplay the role of human activities in driving the observed increase in global temperatures. **

The calorie expenditure for road cycling and mountain biking can vary based on factors such as intensity, terrain, and duration. Generally, road cycling on flat terrain at a moderate pace can burn around 400-600 calories per hour, while mountain biking on varied terrain with hills and obstacles can burn around 500-800 calories per hour. The higher calorie expenditure in mountain biking is due to the increased effort required to navigate the challenging terrain and obstacles. Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **
