fires, global warming

I am sorry that the news is not truthful about a lot of things. I have a long time class mate that fights fires all over the west. Last year 16 of the fires in California was caused by PG&E bad maintenance. After consulting with a foreman that works for Parr electric out of Texas repairing and replacing high power transmission lines. I found the above to be true, Yes we have had less rain than in years past, but it does not give our power companies and out of control (CONTROLED) forest service burns the right to kill and destroy our personal property and forests. We complain about the timbers being cut down and our wild life not having a place to live. Wake up people. The forest fire not only displace our animal population, but also destroys it. My fire fighting friend has told me stories of animals running across the fire roads on fire. We need responsible people to step up and do something about it instead of being lied to about the facts. Than blaming everyone and thing except themselves where the responsibility lies.

SoCal North

I just moved from San Diego to Eugene a few months ago, only to find the region is turning into Southern California North.

Hoq many more years of this can we take before the rivers run dry and the hydro plants fail?

Forest Fires

...and proper forestry management.

This is getting really scary, such little rain!!

The Farmer's Almanac has been close most years, but this year it's the roll of the dice....Here in Brookings we usually get a lot of rain, but this year its horrible...Great weather but its not normal for this time of year, what is going to happen next spring and summer when everything is really dry?? We already had a scary 190,000 acre fire 2 years ago that came 5 miles from town, my heart goes out to all those people in Paradise CA who lost their homes and lives....Time to pray for rain folks!!

Pray for Rain

We concurr completly!!!!! We are praying every day for rain. This is very very scary..and it seems to coincide with pple moving to the pnw en mass. HORRIBLE. We are in issaquah and see heat syress on the red cedars and Tolt River drying up. Heart breaking

Low rainfall!

I'm in agreement Ron and am getting quite fearful as to what next summer will bring. This past winter was relatively dry then we went through a long, hot summer. I have ponds on my land and they aren't filling up. Usually torrential rains during late October and November would have done the job. My wife noticed no geese or ducks. I said there's little water for them to have an easy take off once landing. We usually have flocks of them coming in. We're not too far from the Ridgefield National Wildlife Refuge. The have access to the river and estuaries associated withe Columbia River, but streams and inland ponds that need rainfall are low to dry. I had to dig a grave for one of my pets. The ground was like concrete below several inches and this was in an area of rich topsoil. All we can do is hope and pray. : |

Climate change ... this is going to get worse till Co2 levels dr

You have to understand that c02 is the thermostat of earths biosphere. It really does regulate how much heat is allow to escape into space or hold onto it raising the temperatures. Earth has seen one case of climate change 52 million years ago. But that took thousands of years for animals to adapt. This time around, its only been 138 years since the industrial revolution where co2 has spiked 410 ppm. Co2 has normally moved up and down from 180 to 280 ppm for 6,000 years.


I work outside for a living and the weather patterns are scary I've never in 30 yrs experienced the heat we have had and now not enough snow pack stress on plant material I take care of is obvious I fear for my child and the earth she will and is inheriting

Western Washington Weather

Last year Old Farmer's Almanac stated that we would have a colder than normal winter here in the Seattle area and we didn't see any frost until near November, no snow until Christmas Eve. This year, it says we are to expect a warmer than normal winter.

If last year was colder than normal, then this year it might as well be a rainy summer. I'm hoping that the prediction is wrong and that it actually gets cold this year.
