    I want to be her best friend! I have been telling people this stuff for years and it’s nice to finally see another Christian who is also a scientist that shoots straight and tells the truth about what is happening in the world. Thank you, Katharine! God Bless and keep up the great work!!!

    The response to climate change always seems to focus on what governments and big business need to do. Individuals and familes can make a difference by planting trees and native plants on their own properties. Trees provide shade (cooling the earth) and take in carbon dioxide and release oxygen. Individuals and families can also encourage their local policy and law makers to have pro-tree ordinances and practices.

  • I thank God for you Katharine! I love your spunk and enthusiasm and I admire your courage. May God protect and bless you. Rock on

  • Billy from Brazil

    Hello, very few people that know me!!! My name is Katharine and I am christian!!! Now, let me preach you about… socialist policies to satisfy UN’s will!!! This woman smells, looks and tastes like a big FRAUD!!!

  • Billy from Brazil

    The woman wants to use Science to enforce her worldview… And she EXPLICITLY DECLARES THAT!!! How unprofessional is that??? And people are going to fake she IS NOT doing exactly that??? Lol…

    • Haylie

      Really? you scare people with your negative attitude. What Katherine is stating is factual. Try looking at NASA reports. Look for the positive instead of the negative. What are you doing to help preserve the earth or with climate issues?

    • Stephen Willis

      Don’t you just hate it when people use verifiable, science-based facts to support their claims? How outrageous that anyone would actually base their beliefs on true facts, instead of something they were told to believe.

    This was a warning on 21 -2 – 2013 after satka meteorite on 18 – 2 -2013 that strike satka-Russia. the warning concentrate if this meteorite comes from the moon. so i was afraid that some rocks of the moon are separated, and enter earth field. this happens because we have sent many spaceflights to the moon. so we add more masses on the moon. that lead the moon to go farer from earth – according to my law that i have discovered it on 1993 and published it on 1994. this law is a simple and strict relation between masses and distances. NASA declared after my declaration about 9 years, that the moon is getting more far from earth. if they listen we may avoid many earth disasters, happened and happen…why not?…this may charge USA about many disasters that strike our planet earth.

    someone can sure, what i did say happened or not.

    read what i have written as it is. In next blogs i will explain more about sedrah low and marina’s theories. i wish i simplify and clear what i want to say.

    I have warned before and since satka meteorite-Russia, and i have launched my predictions. have a look and see what i have launched and what is going on. My launches are true: spaceflights
    #earthquakes#land slides#meteorite of satka in Russia, i have warned what is happening now. I have warned how much and how many disasters will the world face if this meteorite is extracted from the moon. why the world keep no action. i publish it for many times, wishing reporters and writers take their responsibility to do something.
    again this what i delivered and ready to deliver more:
    “#Russia#NASA&Caltech#Esvenska#Manituba questions and answers about a Meteorite exploded above the town of Satka, near the city of Chelyabinsk in Russia.
    At the very first we should ask about the meteorite from where it came…is it a random patrolling space object?…if so no major problem up to date. However, if it is a moon’s extraction, this will be so critical case. How do we proof this suggestion?.
    NASA agency-Pasadena- California said that may be 8 or 9 years ago, this from my archive “verify the exact year!…”: the motion of the earth rotation has slow down to be 24H 1.5M and 1.8mili second. Moreover, from their instruments, they founded that the moon had gone away 18 centimeters; they said the moon is farer 3.8 cm/year.
    In addition, from Sedrah law 1994 ” mine “, it has been proofed that the moon is getting away from earth, before nasa declaration more than 9 years. Nevertheless, the scientists of NASA and Caltech-you can have the post and E-mails sent to scientists of both- had disregarded this law before and after their declaration these information about the moon.
    How can we have an answer – proof – whether this extraction is from the moon or not and what are the disasters if so?
    1- Because NASA has a periodic record about the moon distance from earth. Look at the record that before meteorite strike the earth and after it. If the moon slow down its getting far, this piece is-extremely probable-from the moon.
    2- If this the motion comes from farer to nearer that means many meteorites or pieces had been extracted from the moon from the invisible portion, all over the years from the first launch on moon.
    3- This from Sedrah’s law that statements: if we add to or remove a load “mass” from a rotating space object around another, this rotating object will be farer or nearer by a distance estimated from Sedrah’s law and with a speed from another law “not declared yet”. Look at the photos associated on face book you will find a photo from the Egyptian patent office “Sedrah law and marina’s theories” &Svenska letter, Manitoba letter, E-mails…this for journalist and reporters: ensure the date of NASA declaration and declaration of Sedrah law and marina theories.
    4- Earth is getting to be nearer to the sun may be now how much meters is?.
    5- What are the consequences of this meteorite impact:
    a- The temperature will be more 2 or 3 degrees at the conical region of from entering atmosphere to the impact, the next few weeks.
    b- It will lead to successive of earthquakes that strike the earth few weeks coming not so harmful, only if this meteorite is a patrolling space object, cause effect.
    c- If it is extracted from the moon it will be cause and pre sign and will lead to harmful series of earthquakes that strike earth north east latitude20 to 60 up to the area from 15 south west to 35 North West( from 180 east to 180 west). In addition to earth landslides, collapse and tsunamis’.
    d- We should correct the relation between tsunami and earthquakes and this is the correct relation between tsunami and earthquakes: Tsunami occur first leading to series of earthquakes…why? Ask why first and you have the clues. This correction leads to more successful prediction of earthquakes.
    e- Finally, what is the relation between “earthquakes” and “Sedrah law & marina theories”, to raise more the probability of more accurate prediction?…”

    Going to more details

    we should see on papers what is happening on nature

  • Eric Marsh

    I bet Katharine gets some grief from within the conservative evangelical community.

    • Glenn Shrom

      Actually, there is not much about evangelical Christianity to tell us what practical steps we should take to protect our environment, nor to tell us the science of what effect our actions are having on it. We basically are commanded to be good stewards of God’s creation, and then it is up to us to figure out what that looks like. A lot of liberals would not be happy if they had to give up all digital communications and media in order to save the environment. It’s funny how the carbon footprint of our technology gets overlooked, yet air travel gets flack, yet the two have about an equal effect according to science (2% of global greenhouse gas emissions each). Al Gore does not seem happy to tear down his mansions to plant trees that trap carbon on that land instead.

  • Shari Smith

    Who can believe science and therefore the so-called facts any more when so I-called scientists such as the Penn State professor are found committing fraud in his research? And these are the people involved in peer review? Right, we’re supposed to fall in line not questionong the frauds. Then we read that an ubdersea volcano has been found in the Arctic Sea northeast of Norway , also that methane has been observed bubbling up in the Arctic Sea. It doesn’t take a genius to see that either one of these phenomena will cause arctic ice to melt. Anyone can see that, except for those blinded by their bias. So these people want to wreak ecomical mayhem on middle class people who are already staggering under the weight of the Left’s failed economy.

  • Ben Franklin

    Wow, Shari, you are not very well informed. I suggest you watch a bit more NOVA and a bit less FOX news. Dr. Mann was not found committing any “fraud” – not sure what you are talking about there. And the carbon cycle is much better understood than you present – though we continue to find new information all the time.

    Thank God for this woman!!
