Is Climate change Helping the Orca Population

Orca whales of the Pacific Northwest could be encountering a time of increased birth rates.  This is an unprecedented event. There has been very low birth among this species and only lately did their population increased at this rate. The climate change that is responsible for increasing the ocean water temperature, may have brought this about.

Seen close British Columbia’s Active Pass by researcher Jeanne Hyde and boat captain Spencer Domico of the Pacific Whale Watch Association, the calf, named J52, is the fourth orca calf to be seen in the area in three months.

The Center for Whale Research (CWR), a non-profit organization that studies the orca whale populace in the Pacific Northwest, has affirmed the sighting, adding that they will need to lead their own detailed observation to figure out who the mother is.

At the point when initially watched, the calf still had its fetal folds, which implies that it was at most a couple of days old. It seemed healthy to the whale watchers, the CWR said.

The whale watchers were watching a little gathering of whales called J16, a subgroup of the J unit, one of three units in the locale. They at first confounded the new calf with another calf, J50, which had been conceived three months back.

“And as they passed in front of the boat, I saw a small calf surfacing next to J16 and said,’ there’s the baby.'” That is the point at which I told Spencer, ‘I think there are two calves!'”

The CWR screens three major pods of orcas in the area; the J pod, K pod, and L pod, as indicated by the bunch’s website. With the conception of this new orca it brings the populace to the J pod to 27 whales, as indicated by the CWR. The group assessed the aggregate wild populace of this kind of orca to be at 81, yet this won’t be officially measured until the first of July, when the whale evaluation is taken, in view of the quantity of whales alive on July 1 of each year. Analysts need to hold up until the K and L units to come back from their waterfront “forays,” which is usually in June, as indicated by the CWR.

The orca populace in the locale has been in a state of chaos as of late. The whales survival depends on Chinook salmon swimming into the Salish Sea, yet the salmon populace has likewise ended up depleted in recent years and are presently delegated undermined under the Endangered Species Act, as indicated by the Marine Science Center at Fort Worden State Park on Puget Sound. This leaves orcas needing to travel longer distances looking for a relentless sustenance supply and the outcome has been an ascent in malnourishment in some orcas, as per the report.

“J-Pod is certainly doing all it can to rebuild the ranks,” clarifies Michael Harris, Executive Director of the Pacific Whale Watch Association, in the press conference.

    34 years of CO2 science being 97% certain proves they couldn’t be certain and 34 years of climate action failure and global disbelief proves it 100%.
    So how close to unstoppable warming would your science gods have take us before being certain?
    Quote one single CO2 scientist that says they are not allowed to and stop exaggerating and fear mongering like neocons.

    The birth of four new calves in the last couple of months is incredibly good news for the Southern Resident orcas, and something to celebrate, which we all are doing. We must keep in mind, however, that these are the only calves to survive so far in the last two and a half years. The population cannot recover with such a low survival rate. The birth of the new calves also means there are four more very hungry mouths to feed.
    In the last decade the orcas’ death to surviving birth rate has been two to one, with deaths winning. Robust chinook salmon populations are the answer, climate change or not. We must do everything we can to recover chinook.
    Historically, the Southern Residents have depended on the Snake River/Columbia River basin for chinook. Dams built in the 1960’s and 1970’s have blocked this once free flowing river and caused the Snake’s salmon populations to crash. The Southern Residents’ population has declined with the decline of the Snake River salmon.
    The Snake River dams are old and getting older. They are unreliable, inefficient and costly. Taxpayer money now being used to support them can be better spent on more efficient dams with better fish passage measures.
    If we can convince our politicians that the Snake River dams should be breached with minimal costs to taxpayers, we can save the Southern Residents, save salmon and save taxpayer money. This is a win-win-win situation.
