Abstract Marine invertebrate gametes are being spawned into an ocean simultaneously warming, acidifying and increasing in pCO2. Decreased pH/increased pCO2 narcotizes sperm indicating that acidification may impair fertilization, exacerbating problems of sperm limitation, with dire implications for m...
