العالم يكسر رقمه القياسي في الحرارة – مجددا

climate Council of Australia

كشف تقرير أعده مجلس المناخ الأسترالي أن معدل درجة حرارة العالمي قد بلغ ذروته لسنة 2015، كاسرا بذلك الرقم القياسي المسجل لعام 2014 بزيادة قدرها 0.16 درجة مئوية، و علما أن سجلات الحرارة العالمية بدأت تُدون منذ العام 1880. و سَجلت تلك الحرارة القياسية 0.9 درجة مئوية زائدة عن المعدل العالمي للقرن العشرين، آخذة بذلك الاعتبار لنزعة حرارية متواصلة الارتفاع منذ العام 1970 حتى أواخر القرن الماضي

و تغطي هذه النزعة الحرارية مناطق مختلفة على الخريطة العالمية بما فيها الشرق الأوسط و شمال أفريقيا، اللذان يُعدان من المناطق الأكثر عُرضة للخطر البيئي. وقد اتضح هذا الخطر في يوليو الماضي عندما تَسبب مرتفع جوي اجتاح المنطقة لخلق قبة حرارية كانت قد خيمت فوق جنوب العراق و مناطق من إيران، مسببة بدورها درجات حرارة و نسب رطوبة غير مسبوقة في تلك الأماكن الحارة أصلا. ففي مدينة السماوة العراقية على سبيل المثال، بلغت درجة الحرارة المعلنة 48.5 درجة مئوية، بالإضافة إلى درجة تكثف بقيمة 29.5 مئوية – مما يجعل ناتج الحرارة المحسوسة عن طريق جلد الإنسان تبلغ 71 درجة مئوية. أما في البحرين، بلغت تلك الحرارة المحسوسة 53 درجة مئوية

هذا التغيير في المناخ العالمي و ارتفاع معدلات الحرارة هو نتيجة طبيعية للارتفاع الكبير في كمية الغازات الدفيئة المنبعثة إلى المجال الجوي من قبل الصناعات المعتمدة على حرق النفط و الغاز و الفحم، و من المتوقع أن تزداد الأمور سوءا إن لم يتم العمل على خفض تلك الغازات الضارة. و في هذا الصدد، اتفقت 195 دولة في  مؤتمر باريس للمناخ في ديسمبر الماضي على برامج شبه ملزمة قانونيا تهدف إلى تفعيل تغييرات من شأنها الحد من ارتفاع معدل الحرارة العالمي بنسبة درجتين مئويتين حتى نهاية القرن الحالي

The Hidden Components Powering the Renewable Energy Revolution

A rooftop solar system looks simple: panels, an inverter, a battery and a few cables. But beneath that simplicity lies a bill of materials thousands of lines long, where tiny current sensors, magnetic cores, gate drivers, capacitors and connectors quietly determine efficiency, safety and lifespan. These overlooked components—not the solar panels themselves—are why today's residential solar systems are smaller, smarter and far more reliable than those of a decade ago.
