Yet they reflected a common reality: climate change no longer distinguishes between developed and developing nations. Spain recorded temperatures of 43.7 degrees celsius , the Czech Republic reached 41.9 degrees celsius, while Germany experienced 41.7 degrees celsius. Erratic rainfall patternsThis growing contrast illustrates one of climate science’s most important observations: climate change increases variability as much as it changes averages. Human-induced climate change effectively raises the baseline upon which natural variability operates, making both droughts and floods more severe. Climate change is reshaping economies, public health, infrastructure and national security in real time.
