Global Climate Change and Historical Trends in Climate Indicators

Öz

The main cause of climate change is an increase in greenhouse gas emissions, which alters the physical characteristics of the atmosphere and causes climatic perturbations. Rising global mean temperatures have resulted in elevated dew point temperatures and diminished relative humidity. This study thoroughly examines the alterations in global climatic indicators from 1970 to 2023, analyzing trends in critical parameters like air dry bulb temperature (Tk), dew point temperature (Td), dew point depression (DPD), absolute humidity (w), relative humidity (RH), and density (ρ). The findings indicate that climate change is progressing rapidly, heightening the likelihood of drought and severe weather occurrences. In addition, the necessity for immediate action regarding future environmental and socio-economic adaptation strategies was underscored. In this study aims to enhance understanding of the impacts of global climate change and to develop suitable policies grounded in long-term data and climate models.

Küresel İklim Değişikliği ve İklim Göstergelerindeki Tarihsel Eğilimler

Öz

İklim değişikliğinin temel nedeni, atmosferin fiziksel özelliklerini değiştiren ve iklimsel bozulmalara yol açan sera gazı emisyonlarının artmasıdır. Küresel ortalama sıcaklıkların artması, çiğ noktası sıcaklıklarının yükselmesine ve bağıl nemin azalmasına neden olmuştur. Bu çalışmada, 1970-2023 yılları arasında küresel iklim göstergelerindeki değişimler ayrıntılı olarak incelenmiş ve kuru termometre sıcaklığı (Tk), çiğ noktası sıcaklığı (Td), çiğ noktası depresyonu (DPD), özgül nem (w), bağıl nem (RH) ve yoğunluk (ρ) gibi kritik parametrelerdeki eğilimler analiz edilmiştir. Bulgular, iklim değişikliğinin hızla ilerlediğini, kuraklık ve şiddetli hava olaylarının olasılığını artırdığını gösteriyor. Ek olarak, gelecekteki çevresel ve sosyo-ekonomik uyum stratejileriyle ilgili acil eylem gerekliliği vurgulanmıştır. Bu çalışmada, küresel iklim değişikliğinin etkilerinin daha iyi anlaşılmasını ve uzun vadeli veriler ve iklim modellerine dayalı uygun politikaların geliştirilmesini amaçlamaktadır.
