HENRY M. PAULSON JR. – There is a time for weighing evidence and a time for acting. And if thereâ€™s one thing Iâ€™ve learned throughout my work in finance, government and conservation, it is to act before problems become too big to manage. For too many years, we failed to rein in the excesses building up in the nationâ€™s financial markets. When the credit bubble burst in 2008, the damage was devastating. Millions suffered. Many still do. Weâ€™re making the same mistake today with climate change. Weâ€™re staring down a climate bubble that poses enormous risks to both our environment and economy. The warning signs are clear and growing more urgent as the risks go unchecked.
