تخریب ۱۴ درصد از صخره های مرجانی جهان طی یک دهه

نتایج یک بررسی نشان می دهد: یک دهه تغییرات آب و هوایی منجر به از بین رفتن ۱۴ درصد از صخره های مرجانی در جهان شده است.

 بین سالهای ۲۰۱۸ تا ۲۰۰۹ میلادی افزایش مداوم دمای آب دریاها موجب از بین رفتن ۱۴ درصد از صخره های مرجانی در جهان شده که وسعت آن بیشتر از مساحت مجموع صخره های مرجانی استرالیاست.
کارشناسان شبکه جهانی نظارت بر صخره های مرجانی، اطلاعات ارائه شده توسط بیش از ۳۰۰ محقق از ۷۳ کشور جهان را در طول ۴۰ سال جمع آوری کردند که شامل دو میلیون مشاهدات فردی بوده است.
این بررسی نشان داد که تقریبا کاهش شدید پوشش مرجانی با افزایش سریع دمای سطح آب دریا مطابقت دارد و نشان دهنده آسیب پذیری آنها در برابر افزایش دماست و مشخص شد که از بین رفتن صخره های مرجانی با گرم شدن کره زمین ادامه می یابد.
به نقل از سایت اطلاع رسانی سازمان ملل، صخره های مرجانی دارای بالاترین تنوع زیستی در بین اکوسیستم های جهان هستند که آنها را به لحاظ بیولوژیک پیچیده و با ارزش کرده است.
