Recently there was something called Earth Day. Here is a blog that believes many positive developments are taking place on Earth. His top ten:
10) The growing season across the Northern Hemisphere is expanding;
9) Precipitation has increased across the mid-to-high latitudes of the Northern Hemisphere (where most of the world’s crops are grown);
8 ) Higher CO2 levels are leading to more productive plants, including crops such as corn, wheat, and rice …
7) … and contributing to an increasing global output of food products;
6) The combination of the above is leading to a true “greening” of the environment;
5) Global tropical cyclone activity has been declining over the past 20 years and is now near its 40-yr low;
4) The rate of sea level rise has slowed during the past decade;
3) The rate of global temperature rise has remained moderate and likely below the central value of climate model projections for the past 30 years;
2) Evidence continues to mount against high climate sensitivity values.
And, the NUMBER 1 positive climate development for Earth Day 2012,
1) Together, these beneficial trends, along with
enhancement of our energy and other technologies, has the net result of
increasing public health and welfare. For example across the globe, the life expectancy at birth is the longest it has ever been, and continues to climb upwards.
