The best proxy data for Tuvalu appears to come from nearby American Samoa, where NOAA maintains online climate records dating back to the late 1950s. There are absolutely no significant trends in monthly or annual precipitation since the 1970s or 1990s, nor are there any monthly or annual trends in temperatures over the past quarter-century. These non-trend results for the region around Tuvalu arent surprising, since Queensland on the northeastern tip of Australia closest to Tuvalu hasnt seen a trend in annual precipitation since records began in 1900, and certainly no trends since 1970 or 1990. Nor has Queensland seen any significant trends in summer, autumn, winter, or spring precipitation since 1900, 1970, or 1990, either. And Queenslands annual, summer, autumn, winter, or spring temperatures do not exhibit a significant trend over the past quarter-century.
