If you wonder where today’s temperature fits in with the grand scheme of time on Earth since the dinosaurs were wiped out, here’s the history. We start with the whole 65 million years, then zoom in, and zoom in again to the last 12,000 from both ends of the world. What’s obvious is that in terms of homo sapiens history, things are warm now (because we’re not in an ice age). But, in terms of homo sapiens civilization, things are cooler than usual, and appear to be cooling.

OCEAN ACIDIFICATION IS A MYTH

INTRODUCTION

Climate alarmists believe the world is warming, and that this is caused exclusively by man-made carbon dioxide. ‘Global Warming” is now stretched to Climate Change”, but it must be stressed that carbon dioxide can only produce warming: the deceptive change of name does not change the alleged process.

To demonise carbon dioxide further it is supposed to cause ‘acidification’ of the oceans. They claim that anthropogenic carbon dioxide causes the ocean to become more ‘acid’, which dissolves carbonate. This despite the fact that the oceans are alkaline, and have never been acid throughout their existence on Earth. We are implored to reduce the production of anthropogenic carbon dioxide to ‘protect’ the ocean. In this article I show that such claims are baseless, and indeed that carbon dioxide is beneficial to the ocean.
