Over this same period, world population increased by 45%,[227] atmospheric CO2 increased by 10%,[228] and the average global surface temperature (as calculated by NASA) increased by 0.9ºF (0.5ºC).[229] found that a principal measure of worldwide vegetation productivity increased by 6.2% between 19.

We hereby release a random selection of correspondence, code, and documents.

For example, between 19, sea level rose by about 6 inches in the tropical Western Pacific while falling by about the same amount in San Francisco.[238] * The average global sea level has been generally rising since 1860 or earlier, which is about 45 years before surface temperatures began to rise and 75 years before man-made emissions of CO2 reached 1% of natural emissions.[239] [240] [241] * If the trend of the 20th century continues, the average worldwide sea level will rise by about 7 inches (18 cm) during the 21st century.

The 2007 IPCC report uses certain models that project an acceleration of this trend, and the report predicts sea level increases ranging from 7 to 31 inches (18-79 cm) from 1990 to 2100.[242] * Scientists have estimated worldwide sea levels going back to the year 1700 using data from local tide gauges, which are instruments that measure the level of the sea relative to reference points on land. According to some predictions, not long after Bangladesh feels the impact, up to 60 percent of the present population of Florida may have to be relocated. [254] * In 2008, scientists with the Center for Environment and Geographic Information Services in Bangladesh announced that their study of satellite images and maps shows that Bangladesh gained about 1,000 square kilometers of land since 1973.[255] [256] [257] * Coral reef islands are typically found in the Pacific Ocean and are primarily composed of gravel, silt and sand that has accumulated on coral reefs.

It is the “leading international body for the assessment of climate change,” * The first IPCC report (1990) contains the following graph of average global temperature changes over the past 1,000 years based upon proxies.

It shows a “Medieval warm period” that was warmer than the present era and a “Little Ice Age” that was cooler.
