‘We have the knowledge and the tools to act. We have a choice. Future generations will not’
A new report released just days before the start of the Paris climate talks makes it clear why there is so much interest in reaching an agreement to cap global warming. The World Meteorological Organization said it’s all but certain that 2015 will be the hottest year on record.
The global average temperature for the year will probably cross a symbolic threshold, reaching 1.0 degrees Celsius above the pre-industrial era, capping a five-year span that is also the warmest on record, the WMO said, blaming a strong El Niño and human-induced global warming.

FRISCO — For many people, the concept of global climate change remains abstract until they feel the impacts of global warming first-hand — just ask the residents of Sandy Hook, New Jersey or Boulder, Colorado.
That’s completely understandable, and ultimately, the impacts of global warming will mostly play out in the arena of day to day, month to month and year to year weather.
Some areas, like the Southwest, are already starting to see longer and more intense heatwaves and droughts, while other areas, like the coast of Alaska, see rising sees encroach on the land.

FRISCO — High-impact climate extremes and record warmth in many parts of the world marked the 2000-2010 period, according to the World Meteorological Organization, which last week released a report detailing the globe’s climate during the first 10 years of the 21st century.
It was the warmest decade since the start of modern measurements in 1850, with more national temperature records broken than in any previous decade. Along with analyzing global and regional temperatures and precipitation, the report took a close look at extreme events, including heat waves in Europe (2203) and Russia (201o), Hurricane Katrina in the United States of America, Tropical Cyclone Nargis in Myanmar, droughts in the Amazon Basin, Australia and East Africa and floods in Pakistan.
“It is vital that we continue to invest in the observations and research that will improve our knowledge about climate variability and climate change,” said WMO Secretary-General Michel Jarraud. “We need to understand how much of the extra heat captured by greenhouse gases is being stored in the oceans and the consequences this brings in terms of ocean acidification and other impacts,” Jarraud said in the statement.

FRISCO — The New Year is barely a week old, but extreme weather continues, this time in the Southern hemisphere, where parts of Australia reached unprecedented high temperatures, in some cases ranging upward of 120 degrees Fahrenheit. For the sake of comparison, Death Valley reported a reading of 136 degrees way back in July, 1913.
Warmer stratosphere, active polar vortex help speed seasonal recovery

FRISCO — Relatively warm stratospheric temperatures helped limit the size of this year’s Antarctic ozone hole, which disappeared completely by Nov. 10, earlier than in recent years.
Using data gathered from ground stations and weather balloons, the World Meteorological Organization said the warmer temps at an elevation of about 20 kilometers limited the formation of polar stratospheric clouds which, through a chemical chain reaction between water, nitric acid and halogenated reservoir gases cause ozone loss. In this respect, the 2012 ozone hole was similar to the one in 2010, when a sudden stratospheric warming in July and August gave rise to a smaller amount of polar stratospheric clouds than usual.
