We know that:

• Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880, much of this in recent decades. NASA's Goddard Institute for Space Studies has confirmed this.

• The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, as shown by climatology scientists. The United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850. This statistic was likewise confirmed by NASA.

• Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004. Once again, NASA investigated and confirmed this.

• Arctic ice is disappearing at an alarming rate, and the region may have its first completely ice-free summer by the year 2040 or even earlier. To add to this, polar bears and other native species are already suffering from the sea-ice loss.

• Glaciers and mountain snows are rapidly melting. For instance, Montana's glacier park now has only 27 glaciers, compared to the 150 that existed in 1910. In the Northern Hemisphere, thaws a week earlier than usual and freezes end a week later than usual.

• Coral reefs suffered the worst bleaching since 1998 (when they're destroyed by stress from temperature change), with some areas seeing bleach rates of 70%. Scientists expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise causing the currents to change.

• An upsurge in the amount of extreme weather events (such as heat waves and tropical storms) has come with the climate changes.

We also know that:

• Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all of which are greenhouse gases.

• Humans are putting more carbon dioxide into the atmosphere faster than plants and ocean algae can absorb it.

• These gases persist in the atmosphere for years, so that even if such emissions were reduced or completely eliminated today, it would still not cause global warming to immediately cease.

• Scientists have proven that natural cycles in Earth's orbit can alter the planet's exposure to sunlight, which may explain part of the current trend.

We're not entirely to blame, but we are accelerating the process. We do need to pay more attention to what we dump into the world, because if we don't, we're in trouble. Global warming is not some elaborate hoax conjured up by the scientists so they can obtain more money, but it's certainly not our fault alone as some claim.
