क्षति के कारण अपार रूप से प्रकाश तथा उष्मीय ऊर्जा उत्सर्जित कर रहा हैं। पृथ्वी प्रति सेकंड सूर्य की जितनी ऊर्जा अवशोषित करती हैं, उतनी ऊर्जा से एक ट्रेन लगातार दश वर्षो तक बिना रुके चलाई जा सकती हैं। स्वाभाविक है कि ऊर्जा के इतने अपार रूप से हुए अवशोषण से पृथ्वी का द्रव्यमान सदियो से बढ़ रहा है। लेकिन पृथ्वी के द्रव्यमान के सापेक्ष यह उपेछणीय हैं। </p>    </div><noscript><img
